With nearly 3,000 GitHub stars and active development since 2014 through version 14.2.0, Yopass eliminates the universal bad habit of sharing passwords and API keys through Slack messages, email threads, and ticket systems by encrypting secrets entirely in the browser using OpenPGP before anything reaches the server. The Go backend stores only ciphertext — it never sees plaintext — while the React frontend handles all encryption and decryption client-side, generating one-time URLs that self-destruct after a single viewing or when the configured expiration of one hour, one day, or one week passes. File upload support streams encrypted files with configurable size limits, and optional custom password protection adds a second encryption layer beyond the URL-embedded key. The server supports Redis or Memcached as storage backends with automatic key expiration, deploying via Docker Compose in under five minutes or as Kubernetes manifests for production environments. Built-in TLS support works alongside reverse proxy configurations for Nginx, Caddy, and Traefik with automatic Let's Encrypt certificate provisioning. Prometheus metrics expose HTTP request counts, latency histograms, and secret lifecycle counters for Grafana dashboard integration and alerting. Read-only mode enables split-instance deployments separating secret creation from retrieval across different network zones. Multi-language support localizes the interface for international teams. The open-source core under Apache 2.0 provides full self-hosted functionality with no account management required. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. Apache-2.0 licensed.

With 2,600+ GitHub stars, MetaMCP solves the MCP server sprawl problem by aggregating any number of upstream servers into a single authenticated endpoint that any MCP client connects to once. Group servers into namespaces — development tools in one, data sources in another — then publish each namespace as its own SSE, Streamable HTTP, or OpenAPI endpoint with API-key authentication in headers or query parameters, or full OAuth per the MCP Spec 2025-06-18 standard. The aggregation engine discovers tools, resources, and prompts from all active servers in parallel, prefixes tool names with server identifiers to prevent collisions, and applies configurable middleware including tool filtering to reduce context-window bloat and description overrides to improve LLM comprehension. The web management UI lets you configure MCP servers with stdio, SSE, or Streamable HTTP transports, toggle servers active or inactive per namespace, create and revoke API keys per endpoint, and inspect discovered tools with their schemas. Nested MetaMCP support enables hierarchical architectures where one MetaMCP instance consumes another, creating multi-level tool organization with automatic name resolution. Compatible with Claude Desktop, Claude Code, Cursor, Open WebUI, and any MCP-compatible client through a single connection URL. The Docker container packages the TypeScript backend with PostgreSQL for configuration persistence, exposing the management UI on port 12005 and MCP endpoints on configurable ports. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. MIT licensed.

Deploy on RepoCloud with a dedicated VPS, keeping all financial data private under the GPL-3.0 license.

With 3,900 GitHub stars, 140 contributors, and 380 releases since its 2022 launch, Grafana OnCall delivers developer-friendly incident response that routes alerts from any monitoring system to the right engineer at the right time through the right channel. The platform accepts alerts via unique API URLs from Alertmanager, Grafana Alerting, Zabbix, Datadog, Pagerduty-compatible sources, Jira, inbound email, and generic HTTP webhooks, then applies routing templates to direct each alert to the appropriate escalation chain. Escalation chains define notification sequences — notify the primary on-call via Slack, wait 5 minutes, escalate to SMS and phone, wait 10 minutes, page the secondary on-call and notify the engineering manager — continuing until acknowledgment or resolution. On-call schedules support multi-layer rotations with overrides, shift swaps, and timezone-aware handoffs rendered directly inside Grafana dashboards. ChatOps integration publishes alert groups to Slack channels and Telegram groups with interactive buttons for acknowledge, resolve, and silence actions. Template engines based on Jinja2 control alert grouping, appearance rendering, and behavioral automation. The REST API enables programmatic management of integrations, schedules, and escalation policies. Deploy via Docker Compose with PostgreSQL, Redis, and Celery workers alongside your existing Grafana instance. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. GNU AGPL v3 licensed.

High-resolution weather forecasts became a free commodity because of Open-Meteo - and this deployment puts the whole open-source engine on your own infrastructure. The public open-meteo.com service aggregates national weather models (NOAA GFS, DWD ICON, ECMWF, Meteo-France, and others) into one consistent JSON interface; self-hosting gives you that same API without rate limits, third-party dependency, or usage metering. The architecture is two cooperating services: the API server exposes forecast endpoints fully compatible with Open-Meteo query parameters - latitude, longitude, hourly and daily variables like temperature, precipitation, wind, and radiation - while a background sync worker downloads fresh weather model data on a configurable interval into a shared persistent volume at /app/data, so forecasts stay current and survive restarts without re-downloading. You control which weather models to mirror, which variables to store, how much historical depth to keep, and how often to refresh - meaning a lean deployment can sync only the model and region you actually query. Responses are plain HTTP/JSON, so integration with dashboards, Home Assistant-style automations, agricultural monitoring, IoT fleets, or any application takes minutes. For anyone making thousands of forecast calls a day, replacing a metered weather API with your own instance turns a recurring bill into a flat infrastructure cost.

Comp AI turns the months-long slog of SOC 2, ISO 27001, HIPAA, and GDPR certification into a largely automated process by connecting to your existing infrastructure and continuously collecting the evidence auditors actually ask for. Point it at your AWS account, Google Cloud project, GitHub organization, or any of 580+ supported integrations, and autonomous agents pull configuration snapshots, access logs, encryption status, and policy compliance data on a recurring schedule so your compliance posture reflects reality rather than last quarter's manual export. The AI policy engine analyzes your tech stack, team structure, and risk tolerance to generate organization-specific policies for information security, access control, incident response, data retention, and vendor management; no two companies get the same boilerplate. An open-source device agent runs on employee machines checking disk encryption, firewall status, screen lock settings, password length, and antivirus presence around the clock, flagging failures the moment they occur instead of surfacing them during an audit. Built-in penetration testing agents scan your codebase and API endpoints for vulnerabilities like SQL injection and output audit-ready reports. The vendor risk management module scores third-party services and surfaces compliance gaps before they become findings. A public trust center lets prospects verify your compliance status directly, eliminating security questionnaire bottlenecks. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. AGPL-3.0 licensed.

Macro merges email, team chat, collaborative documents, task management, CRM, and video calls into one keyboard-driven application where AI agents operate across the entire workspace with shared team memory, replacing the Slack plus Notion plus Linear plus Superhuman plus HubSpot stack with a single deployment. The email module provides a multi-account unified inbox with keyboard shortcuts, shared team inboxes, and Gmail integration. Team messaging offers channels and direct messages designed for technical discussions with threaded conversations. The task system draws from Linear with board and list views tightly integrated with channels, email threads, and AI agents. Real-time collaborative documents use CRDT synchronization via Loro for conflict-free editing with Markdown-native formatting and @mention linking. A 2D canvas board embeds @links to tasks, files, and emails for visual project planning. AI agents access unified team-level memory spanning all workspace modules, taking autonomous actions across email, chat, tasks, and documents through MCP-compatible tool interfaces. Video calls include recording, transcription, and automatic logging to team memory. The CRM module tracks customers and contacts with custom properties, email synchronization, and data enrichment. Eighty-plus Rust microservices on the Axum framework handle backend operations while a SolidJS static SPA delivers the frontend with instant search and real-time collaboration. Docker Compose deployment provisions the complete service stack with PostgreSQL, Redis, OpenSearch, and FusionAuth authentication. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. AGPL-3.0 licensed.

With over 5,100 GitHub stars and eight years of active development since 2016, Shlink has become the definitive self-hosted URL shortener for teams that need unlimited links, full visitor analytics, and complete data ownership without per-link pricing or monthly caps. The PHP backend built on the Mezzio framework with Doctrine ORM serves redirects through any number of custom domains on a single instance, generating unique short codes or accepting custom slugs including multi-segment paths and emoji characters. Every click is tracked with anonymized visitor data including geolocation by country, city, and coordinates, browser and operating system identification, referrer source, and device type classification, all stored in your choice of MySQL, MariaDB, PostgreSQL, Microsoft SQL Server, or SQLite. Dynamic redirect rules route visitors to different destinations based on geolocation, device type, or browser language, enabling targeted campaigns from a single short URL. The REST API exposes every operation with OpenAPI documentation and an interactive sandbox at api-spec.shlink.io, while the CLI provides equivalent functionality for scripting and automation. The official progressive web app at app.shlink.io manages multiple Shlink instances from a single interface with URL creation, tag management, and detailed visit charts. Real-time event integration supports both Mercure and RabbitMQ for webhook-style notifications on new visits. Third-party imports migrate existing short URLs from Bitly and YOURLS with visit history preserved. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. MIT licensed.

Komodo puts every server, container, and deployment pipeline behind a single dashboard where you build, ship, and monitor Docker workloads across unlimited hosts. Lightweight stateless agents install on each connected server and report CPU, memory, and disk metrics back to the Rust-powered core, giving you real-time visibility without heavyweight monitoring stacks. Docker Compose stacks deploy directly from the UI or link to Git repositories with webhook-triggered automatic redeploys on push. A built-in CI pipeline compiles versioned Docker images from source, with optional AWS spot instances for burst build capacity. For orchestration at scale, Docker Swarm management handles node configuration, service deployment, and multi-node stack orchestration from the same control plane. Browser terminal sessions open persistent named shells on servers and inside containers, complete with shared team access and scriptable Actions that chain executions into multi-stage procedures. Infrastructure-as-code support defines all resources declaratively in TOML files within a Git repository, keeping production state version-controlled and auditable. Granular role-based access control with user groups, per-resource permissions, and OAuth through GitHub and Google keeps teams operating within defined boundaries. A full OpenAPI specification, dedicated CLI, and typesafe client libraries for Rust and TypeScript make programmatic integration straightforward. With 12,000+ stars and active development, the community continues expanding multi-architecture builds and Swarm tooling.

What Jellyfin is for video, Komga is for comics, manga, BDs, magazines, and eBooks: point it at folders of CBZ, CBR, CBT, PDF, and EPUB files and it becomes a proper library with cover art, embedded metadata import, and per-user reading progress. The responsive web reader handles multiple reading modes - left-to-right for western comics, right-to-left for manga, webtoon scrolling - while collections and read lists organize crossovers and story arcs, with ComicRack .cbl read list import for existing curation. Its openness is the real differentiator: OPDS v1.2 and v2.0 feeds serve virtually every reader app (Panels, Moon+ Reader, Mihon/Tachiyomi, KyBook), with OpenSearch and page-streaming extensions so mobile apps fetch pages on demand instead of whole archives. E-ink support is built in, not bolted on - Kobo devices sync directly against Komga instead of Kobo's servers, with two-way read progress, on-the-fly KEPUB conversion via Kepubify, and optional proxying so official Kobo purchases still work; KOReader sync covers everything else. Multi-user management brings per-library access control, age restrictions, and label restrictions for family setups. Housekeeping tools detect duplicate files and duplicate pages, and a REST API feeds a healthy ecosystem of community scripts. Runs from a single Docker container with embedded SQLite.

CommaFeed delivers the Google Reader experience on your own infrastructure with modern performance characteristics. The Quarkus-based Java backend compiles to native code via GraalVM, achieving sub-second cold starts and 50MB memory footprint — a fraction of traditional JVM RSS readers. Four distinct layouts (title-only, expanded, magazine, and card) with light and dark themes adapt to any reading style, while comprehensive keyboard shortcuts cover navigation, marking, starring, and feed management without touching a mouse. The Fever-compatible API and newly added Google Reader API connect native iOS and Android apps (Reeder, Unread, FeedMe, ReadKit) directly to your instance. Per-feed push notifications through ntfy, Gotify, or Pushover alert you to new articles instantly. The visual query builder for automatic read-marking rules replaces raw expression syntax with an intuitive condition editor supporting title, content, author, and URL matching. OPML import and export enable seamless migration from any RSS service. Custom CSS and JavaScript injection let power users completely restyle the interface, while the browser extension adds one-click subscription from any website. Docker images for linux/amd64 and linux/arm64 with H2 embedded database require zero configuration to start. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. Apache-2.0 licensed.

Command and automate your entire fleet of 3D printers without relying on proprietary cloud services using Bambuddy, a self-hosted management hub that delivers local network control, print scheduling, and job archiving for Bambu Lab hardware. Print shop operators can route slicing output directly from Bambu Studio or Orca Slicer through virtual printer proxies that emulate physical machines while automatically cataloging print files in a searchable 3D repository. The automated dispatch engine assigns queued gcode files to available printers based on required nozzle temperatures, build plate dimensions, and matched multi-color filament slots. Users can inspect live camera streams across multiple printing beds simultaneously, verify empty build plates before dispatching new jobs, and generate stabilized timelapse videos with custom music. Integrated smart plug connectors automatically cut power to idle machines when print cycles finish and trigger push notifications to Discord or mobile devices if thermal anomalies or mechanical pauses occur. Farm managers can schedule maintenance alerts based on cumulative motor runtime, track spool inventory levels across storage locations, and synchronize printing configurations across duplicate hardware setups. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. GNU AGPL v3.0 licensed.

A complete WhatsApp Business Platform covering messaging, chatbot automation, and voice calling with IVR — a combination most self-hosted projects never attempt. The Fastglue/fasthttp backend processes WhatsApp Cloud API webhooks through PostgreSQL and Redis into a real-time WebSocket layer powering instant chat updates across a Vue 3 frontend built with shadcn-vue and TailwindCSS. Chatbot automation supports keyword triggers, multi-step conversation flows with branching logic, AI-powered responses from OpenAI, Anthropic, or Google models, knowledge base integration via vector stores, and seamless handoff to human agents when the bot gets stuck. The visual IVR builder uses a drag-and-drop node canvas where you wire greeting prompts, DTMF menu capture, HTTP callbacks to external APIs mid-call, business-hours routing by IANA timezone, agent team transfers with hold music, and reusable sub-flows. Every call recording streams encrypted to your S3-compatible bucket with retention you control. Multi-tenant architecture isolates organizations with separate data, roles, and API keys while a unified inbox presents both chat and call conversations to agents in a single dashboard. Meta-approved template management, bulk campaign messaging, analytics tracking, and a full REST API round out the platform. Deploy via Docker Compose with Postgres and Redis included. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. AGPL v3 licensed.

Subtitles are the one chore Sonarr and Radarr leave behind - Bazarr finishes the *arr media stack by automating them. It connects to both via their APIs and mirrors their libraries - it doesn't scan disk itself, it manages exactly what your *arr apps index. For every monitored episode and movie it checks existing internal and external subtitles against your language profiles, then hunts missing ones across dozens of providers - OpenSubtitles.com, Podnapisi, Addic7ed, Subscene, and many regional sources - covering 184 subtitle languages including forced/foreign-dialogue tracks. Matching is smarter than filename guessing: releases are compared by release group and source, some providers support exact file-hash matching, and every downloaded subtitle gets a percentage score. Set a minimum score per Sonarr/Radarr connection and Bazarr rejects weak matches; enable upgrades and it replaces previously downloaded subtitles when better ones surface. Out-of-sync files get fixed too - automatic subtitle synchronization realigns timing after download, triggered only below a configurable score threshold so good subs aren't touched. Per-show and per-movie language configuration, download history, manual on-demand search, and adaptive searching that throttles provider API calls round it out, all behind a clean Sonarr-style web UI written in Python. If your library serves multilingual viewers, this removes the last manual step.

Plunk consolidates transactional emails, marketing campaigns, and drip automation into one platform riding AWS SES at roughly one-tenth of a cent per message, with zero per-contact charges regardless of list size. The Turborepo monorepo architecture separates the Express.js API server (handling REST requests with Prisma ORM against PostgreSQL) from a dedicated BullMQ worker process that consumes email, campaign, and workflow jobs independently for fault isolation and horizontal scaling. Transactional emails support HTML bodies, template variable substitution via React Email components, attachments, and custom headers with dedicated SMTP relay on ports 465 and 587 for integration with existing frameworks. The campaign system sends newsletters and product updates to full contact lists or dynamically segmented audiences based on contact properties and behavioral events, with scheduling, A/B testing, and performance tracking for opens, clicks, and bounces. The workflow automation builder creates event-triggered sequences with delays, conditional branches, and webhook steps for lifecycle campaigns like onboarding drip sequences and re-engagement flows. Contact management stores unlimited contacts with custom data fields, CSV import, full activity history, and dynamic segmentation. Custom domain verification with DKIM and SPF ensures deliverability, while inbound email processing handles incoming messages with custom routing rules. Docker Compose deployment runs five containers including PostgreSQL, Redis, MinIO for S3-compatible storage, and ntfy for notifications. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. AGPL-3.0 licensed.

Security-conscious IT departments pick Passbolt for its cryptography: every user holds an OpenPGP key pair, and shared credentials are encrypted individually to each recipient's public key - real end-to-end encryption, not a vault password handed around. All crypto runs client-side in the mandatory browser extension (distributed and signed through the Chrome and Firefox stores, deliberately separating the crypto code from the server that stores ciphertext); private keys and passphrases never touch your instance, and the server admin cannot read a single secret. Authentication uses the challenge-based GpgAuth protocol, secrets are digitally signed to verify sender integrity, and metadata encryption extends protection to resource names and URLs. Day to day it behaves like a polished commercial manager: auto-fill and auto-save in forms, strong password generation, anti-phishing protection, TOTP storage, folder hierarchies shared per-user or per-group with fine-grained permissions and instant cryptographic revocation. Native iOS, Android, and desktop apps ship alongside a JSON API, CLI, and SDKs for CI/CD secret retrieval and rotation. The PHP server runs on MariaDB and is AGPL-licensed open source - including the paid tiers' codebase - with published security audits.

Coroot uses eBPF to capture metrics, distributed traces, logs, and continuous CPU profiles directly from the Linux kernel, delivering full observability without any application code changes, SDKs, or sidecars. From the first minute of deployment, an automatically generated service map covers every microservice, database, message queue, and external dependency with request rate, error rate, and latency measurements. When a service breaches its SLO, AI-powered inspections analyze telemetry across all dimensions to pinpoint the root cause and send a single consolidated alert with findings, replacing the flood of fragmented notifications typical of traditional monitoring. Deployment tracking automatically discovers Kubernetes rollouts and compares each release against the previous one to detect performance regressions, resource spikes, and cost impacts without CI/CD pipeline integration. Continuous profiling captures CPU flame graphs down to the line of code with negligible overhead. Integrated cost monitoring tracks cloud spending across AWS, GCP, and Azure, attributing expenses to individual services and deployments. Coroot supports Prometheus, OpenTelemetry, and ClickHouse as data sources and works identically on Kubernetes clusters, virtual machines, and bare-metal hosts. 7,700+ GitHub stars. Apache-2.0 licensed.

With over 8,000 GitHub stars and continuous development since 2020, LibrePhotos delivers the core intelligence of Google Photos — face recognition, object detection, semantic search, and automatic album generation — entirely on your own hardware without sending a single photo to a third-party server. The Django 5 backend processes uploaded media through a machine learning pipeline that runs face detection via the face_recognition library, clusters identified faces using scikit-learn and HDBSCAN, generates image captions through BLIP and Moondream 2, and classifies scenes using Places365 or Google's SigLIP 2 vision-language model with zero-shot classification against 900+ real-world tags. Semantic search lets you find photos by natural language queries like "sunset at the beach" without manual tagging, while metadata search filters by person, camera, lens, file type, and filesystem path. The React 18 frontend built with Vite presents a timeline view, fullscreen lightbox with slideshow mode, photo detail sidebar showing location and people, and a folder navigation view with breadcrumb paths. RAW files from any camera are converted via ImageMagick, videos processed through FFmpeg, and Live Photos paired with their RAW+JPEG counterparts as unified entries. Public album sharing via link provides fine-grained privacy controls, and duplicate detection uses perceptual hashing to identify near-identical images. Deployment runs as a single unified Docker container or via Docker Compose with Kubernetes manifests also available. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. MIT licensed.
