PrivateBin shares text and files with true zero-knowledge encryption: the server stores only ciphertext it cannot decrypt because the key exists exclusively in the URL fragment that never reaches the server. With over 8,400 GitHub stars and 500,000+ Docker pulls, it has become the standard for privacy-respecting paste sharing where not even the hosting operator can read stored content. All encryption uses 256-bit AES in Galois Counter mode performed entirely client-side in the browser. Burn-after-reading mode destroys pastes on first view, while configurable expiration timers automatically purge content after periods ranging from five minutes to forever. Optional password protection adds a second encryption layer requiring recipients to enter a passphrase before decryption occurs. Discussion threads enable anonymous or nickname-based commenting on pastes with IP-based identicon avatars for visual identity. Markdown rendering with live preview formats pastes as styled HTML, and syntax highlighting through prettify.js supports dozens of programming languages across four color themes. File upload support enables sharing images, PDFs, and media files with in-browser preview. QR code generation converts paste URLs for mobile device transfer. Customizable templates include Bootstrap 5, classic Bootstrap CSS, and Darkstrap themes. Storage backends support filesystem, MySQL, PostgreSQL, SQLite, Amazon S3, and Google Cloud Storage. Deploy via Docker with the privatebin/nginx-fpm-alpine image on port 8080.

With over 3,600 GitHub stars and a philosophy of deliberate simplicity, OliveTin eliminates the need for SSH sessions, admin panels, and complex automation platforms by letting you define shell commands in a YAML config file and access them as clickable buttons through a clean browser interface. The Go binary consumes only a few megabytes of RAM, running on everything from tiny ARM and RISC-V devices through Linux VMs, containers, macOS, and Windows. Each button executes a predefined shell command with optional typed arguments that render as dropdowns, text fields, and validated inputs, preventing free-form command entry while giving users controlled access to server operations. Access control lists define exactly who can view or run each action — guests, family members, or junior administrators see only the buttons they are permitted to use. Entity templates generate actions dynamically from lists of hosts, containers, or other resources, creating one template that produces many buttons without manual duplication. Flexible triggers extend beyond browser clicks: cron schedules, webhooks, calendar file events, and filesystem watchers run actions automatically when conditions are met. Authentication supports OAuth2, JWT, and header-based methods for integration with reverse proxies and identity providers. Dashboards organize actions into folders and fieldsets for clear navigation across dozens of commands. No plugin system, no extension marketplace, no premium tiers — every feature ships in the single open-source release.

Homeowners and facility operators deploy Viseron to turn standard RTSP and ONVIF security cameras into a self-hosted network video recorder with local AI object detection, face recognition, and license plate reading. Instead of uploading private camera feeds to subscription cloud services, you monitor low-latency WebRTC live streams, scrub through an interactive event timeline, and review 24/7 continuous recordings directly from a responsive web dashboard. You can draw custom detection zones and privacy masks in the visual camera tuning editor to filter out street traffic, while lookback buffering captures footage several seconds before motion or an object triggers an event. Pluggable computer vision pipelines connect your cameras to YOLOv7 Darknet, Google Coral EdgeTPU, CompreFace, dlib, and CodeProject.AI to classify people, vehicles, known faces, and license plates in real time. Tiered storage policies automatically migrate older video segments from fast NVMe drives to high-capacity archival disks based on age and quota rules. Bidirectional MQTT integration and Home Assistant auto-discovery let you toggle cameras on demand, ingest external motion sensors, and dispatch instant snapshot alerts to Telegram or Discord.

Any blog, documentation site, or static website can host a complete comment section by running its own Waline server, with Markdown, emoji, reactions, and moderation tools included. A visitor writes as a guest, registers an account, or signs in with GitHub, Twitter, Facebook, Weibo, or QQ, and a live preview shows the formatting before anything is posted. Comments accept tables, strikethrough, highlighted code blocks, TeX formulas, custom emoji packs, and Giphy GIF search. On submission, a sanitizer strips scripts and styles while Akismet, per-IP rate limits, keyword and IP block lists, duplicate detection, and reCAPTCHA or Turnstile screen for spam, and an optional review queue holds the comment back until a moderator approves it. The site owner then hears about it by email, WeChat, QQ, Telegram, PushPlus, Discord, or Lark, and the commenter receives reply emails. Once published, readers react with up to nine emoji and sort threads by latest, oldest, or hottest, while pageview and comment counters can appear anywhere on a site and recent-comment and top-commenter widgets fill sidebars. Moderators edit, approve, flag, or delete from the web admin panel, manage users and custom labels, and import earlier discussions from Disqus, Twikoo, Valine, Typecho, Artalk, Commento, or WordPress. Comments stay in your own database, and the widget offers a dark theme and ten languages.

No spreadsheet has to track which service owns which port, because portracker discovers every service and port on your servers and keeps the list current from a self-hosted dashboard. Begin with a single port, shown with its owning service, its source (Docker or the host system), and its address, with internal container ports told apart from ports published to the host. Step back and ports gather into services: expandable cards carrying an icon, a health dot, and a port count, in list, grid, or table layouts, where a Why this status popover names the failing component and the rule that fired. Step back again and each server gets its own panel with hostname, OS, CPU, memory, and uptime, plus TrueNAS apps, VMs, and LXC containers once an API key is added. Step back once more and the whole fleet appears, because other portracker instances can be linked as peers, a VM's instance can be nested under its host, and every server can be searched at once. Along the way, rename services, hide the noisy ones, attach notes, act on a selection in bulk, or press Generate port for an unused number before deploying something new. Optional sign-in with a first-run setup wizard, an autoxpose link that shows public URLs and SSL status, light and dark themes, and keyboard shortcuts finish the picture.

Duckle compiles visual data integration pipelines into vectorized analytical SQL executed on an embedded columnar engine, eliminating the overhead and cloud egress costs of traditional ETL infrastructure. Engineers can construct data pipelines on a drag-and-drop canvas, connecting hundreds of data sources spanning relational databases, cloud object storage, streaming event buses, vector databases, and SaaS application programming interfaces. An interactive mapping editor enables complex joins between primary data inputs and lookup streams with typed transform expressions and live sample inspections. Built-in transformation blocks execute change data capture, slowly changing dimensions, aggregation rollups, and integrated dbt models with zero row-based metering or cloud egress fees. Teams schedule headless production executions through a dedicated web console equipped with role-based access management, execution audit trails, and automated failure alerts dispatched to webhook endpoints. Embedded Model Context Protocol capabilities allow AI coding assistants to validate schema configurations, inspect execution logs, and trigger batch workflows directly through conversational commands. Workspaces store entire pipeline definitions as individual files in version control, ensuring reproducible deployments across staging and production environments.

When an AI agent breaks in production, Tracely freezes that exact run into a replayable regression test and blocks the pull request that would ship the bug again. Span soup hides the failure. OTLP/HTTP traces group into conversation threads, and a waterfall marks the failing span in red with its input and output. Nobody knows if an answer was good. Evaluators sit as columns on the trace table, mixing model-free checks with LLM judges at conversation, run, or span level. Thirty-one broken runs, one issue. Clustering turns them into a single counted issue and can suggest the evaluator that would have caught it. A fix nobody can prove. One click promotes a failing trace into a hermetic case with recorded fixtures and a fail-to-pass contract, and scenarios send a red-team model after an adversarial goal. Model bills on every CI run. The suite replays offline with no API keys and no model spend, and tracely gate posts a commit status, comments on the pull request, and blocks regressions. No warning when it breaks again. Alert flows drawn on a canvas react to failed gates, broken conversations, unseen failure modes, or rising failure rates by messaging Slack, sending email, calling a webhook, or prompting an LLM. Coding agents can read traces and write evaluators through an MCP endpoint.

By turning any browser into an interactive trivia controller and live scoreboard, Razzia gives event hosts, educators, and communities a self-hosted multiplayer quiz platform that replaces Kahoot. Players join in seconds with a six-digit room PIN or scannable QR code on their smartphones, while the host drives the shared screen from a password-protected manager console. Build quizzes directly inside the browser-based editor or import portable JSON files with single-choice, multiple-choice, numeric estimation, and ungraded survey questions. Attach images, audio clips, or video files up to 100 MB to any prompt, group questions into themed round categories, and display explanatory notes when correct answers are revealed. Scoring adapts to your rules: reward fast responses with time-weighted points, apply strict, balanced, or lenient multi-select grading, deduct penalties for wrong guesses, or switch to survey mode to gather live audience polls without a leaderboard. Hosts can lock rooms mid-game, enable automatic nickname generation, hide question prompts on player screens, and configure auto-advance timers between rounds. Drop a custom theme file and logos into the branding folder to white-label colors, fonts, and backgrounds, or connect physical ESP32 hardware buzzers over the documented WebSocket protocol.

Instead of manually hunting through indexers and stitching chapter files together, ReadMeABook automates the entire audiobook request, download, and M4B library organization pipeline for Audiobookshelf and Plex. Users search an Audible-backed catalog by title, author, narrator, or series, inspect full book summaries with runtime and publisher metadata, and submit one-click requests from a clean browser portal. Once approved, the engine queries Prowlarr across torrent and Usenet indexers, dispatches releases to qBittorrent or SABnzbd, and monitors download progress until completion. Multi-file MP3 downloads merge automatically into a single chapterized M4B audiobook via FFmpeg, complete with embedded cover art, narrator tags, and series ordering metadata before triggering a media server library scan. Not sure what to listen to next? BookDate pairs OpenAI, Anthropic Claude, or local LLM endpoints with a swipeable card deck that learns your reading tastes and queues new titles with a single swipe right. Optional e-book sidecar fetching grabs companion EPUB or PDF files alongside audio releases, while multi-user approval queues, OIDC single sign-on, Goodreads shelf syncing, and Discord, Pushover, Apprise, or ntfy notifications keep household libraries running smoothly.

Browser Use Web UI lets you describe a web task in plain English and watch as an AI agent autonomously navigates pages, clicks buttons, fills forms, and extracts information without writing any automation code. Backed by over 16,000 GitHub stars, the Gradio-based interface supports 14+ LLM providers through a unified abstraction layer: OpenAI GPT, Anthropic Claude, Google Gemini, Azure OpenAI, DeepSeek, and local Ollama models are all configurable via dropdown menus without touching code or environment files. The BrowserUseAgent handles interactive single-task automation with step-by-step LLM decision-making and vision-based page understanding, while the DeepResearchAgent orchestrates multi-step research workflows using Langgraph state machines that spawn parallel browser instances with asyncio concurrency control. Custom browser support connects your existing Chrome profile to preserve logins, cookies, and sessions across agent runs, eliminating re-authentication overhead. Persistent browser sessions maintain complete interaction history between tasks for debugging and demonstration. The Docker deployment bundles Chrome, Playwright, and a VNC server in a single container, exposing the Gradio interface on port 7788 and a noVNC viewer on port 6080 for real-time observation of agent behavior. MCP integration via MultiServerMCPClient enables external tool access. Screen recording captures agent workflows as video for review and documentation.

When nightly SQL, Spark, and Python jobs outgrow cron, Apache DolphinScheduler replaces the tangle with a visual workflow orchestrator where every dependency is a line on a drag-and-drop canvas. More than 30 built-in task types cover Shell, SQL, Python, HTTP, Spark, Flink, Kubernetes, SeaTunnel, and Jupyter, while logic nodes add sub-workflows, conditions, switches, and dependencies across projects. Workflows can also be written as code through a Python SDK, YAML, or the Open API and run on timezone-aware cron schedules. Backfill reruns a workflow across a date range or a hand-picked list of dates, in serial or parallel, and any instance can be modified, rolled back, and rerun without touching the saved template. Kill, pause, and resume running tasks, and choose whether a failure ends the run or lets parallel branches continue. Alert groups route results to Email, Slack, Telegram, PagerDuty, Feishu, DingTalk, webhooks, or custom scripts. Tenants, worker groups, and environments isolate teams on shared infrastructure, with project and data source permissions. A Resource Center stores scripts and task files locally or on HDFS, MinIO, and cloud object storage, and the monitor page shows master, worker, and database health at a glance. Standalone, Cluster, Docker, and Kubernetes deployments scale from one node to many masters and workers that can join or leave a running cluster.

Garnet is Microsoft Research's cache-store built on .NET that speaks the Redis RESP wire protocol while delivering up to 10x higher throughput and 4x lower tail latency than comparable alternatives on identical hardware. The Tsavorite storage engine provides a cache-friendly, shared-memory architecture scaling linearly across CPU cores, supporting both in-memory operation and tiered storage across local SSDs and Azure Storage for datasets exceeding available RAM. Cluster mode enables sharded deployments with replication, dynamic key migration for live rebalancing, non-blocking checkpointing, and automatic failover using standard Redis cluster commands. The RESP implementation covers raw strings, sorted sets, lists, hashes, sets, bitmaps, HyperLogLog, streams, pub/sub, Lua scripting, and client-side transactions, allowing StackExchange.Redis, Jedis, redis-py, and other Redis clients to connect without modification. C#-based extensibility lets developers define custom commands and new data types as server-side stored procedures, compiled and loaded at runtime without restarting the server. TLS encryption, ACL-based access control, and operation logging complete the production feature set. Deployed across Microsoft services including Windows & Web Experiences, Azure Resource Manager, and Azure Resource Graph. Nearly 12,000 GitHub stars. MIT licensed.

HyperDX correlates logs, metrics, traces, session replays, and errors in a single interface so engineers can resolve production incidents in minutes instead of hours. Nearly 10,000 GitHub stars reflect its role as the integrated UI layer for the ClickStack blueprint endorsed by ClickHouse. The platform connects to any ClickHouse cluster as its storage backend, working with existing table structures without requiring data migration or proprietary ingestion formats. An intuitive Lucene-like search syntax supports full-text queries and property filtering like level:err or service.name:api without needing SQL, while native JSON string querying and event delta analysis surface anomalies in high-cardinality datasets. One-click cross-signal correlation lets you jump from a log line to its distributed trace, from a slow span to associated logs, or from a frontend session replay to the backend errors it triggered. The OpenTelemetry Collector accepts telemetry via OTLP on gRPC port 4317 and HTTP port 4318, supporting automatic instrumentation for Node.js, Python, Java, Go, Ruby, and browser applications. APM tracks HTTP request latency, database query duration, and external service calls with trace waterfall visualizations. Configurable alerts trigger via webhook, Slack, PagerDuty, or email when thresholds are breached. Deploys via Docker Compose with ClickHouse, MongoDB, Redis, and the OpenTelemetry Collector.

Backed by 9,000+ GitHub stars and developed by a Germany-based team with deep FIDO2 expertise, Hanko delivers the open-source authentication platform that replaces Auth0, Clerk, and Firebase Auth with a passkey-first architecture built on phishing-resistant WebAuthn credentials. The Go backend exposes both public and administrative HTTP APIs handling passkey registration and login, password authentication, email passcodes, TOTP-based MFA, security key verification, server-side sessions with remote revocation, and JWT issuing with configurable expiry and refresh policies. OAuth SSO connects Apple, Google, GitHub, Microsoft, and custom OIDC providers, while SAML Enterprise SSO integrates corporate identity providers for single sign-on across the organization. Hanko Elements provides framework-agnostic web components that embed complete onboarding, login, and user profile flows into any application with two lines of code, fully customizable via CSS variables and supporting i18n with custom translations. The JavaScript frontend SDK handles API communication, credential management, and session state for teams building custom authentication UIs without the pre-built components. Webhooks notify external services of authentication events including user creation, login, email verification, and password changes. Privacy-first design principles enforce data minimalism with user-deletable passwords and configurable identifier strategies supporting email-only, username-only, or combined approaches. Docker deployment starts the backend with PostgreSQL or MySQL, serving both APIs on configurable ports.

Standard Notes keeps your notes, files, and tags encrypted on your device before anything touches the network, meaning the server stores only ciphertext it cannot read. Cross-platform sync across desktop, mobile, and web delivers fast, conflict-free updates on unlimited devices with the same zero-knowledge guarantee that only your password can decrypt your content. The V2 server architecture condenses everything into four Docker containers consuming roughly 570MB RAM total (down from 13 containers and 1.7GB in the legacy setup), with startup under one minute. Revision history automatically preserves every version of every note, so recovering deleted text or reverting to a previous state never depends on manual backups. A nested tag system organizes thousands of notes with hierarchical categorization that goes well beyond flat folder structures, while search operates entirely on client-side decrypted content. File attachments of any type encrypt and sync alongside notes with identical end-to-end protection. Multiple editor options span plain text, Markdown with preview, and rich formatting to fit different writing workflows. Two-factor authentication via TOTP with email backup codes adds a second barrier beyond your password. An optional separate container serves the web frontend, providing browser access to your encrypted vault without depending on standardnotes.com infrastructure. With 5,500+ GitHub stars and active development, the project continues expanding editor plugins and sync improvements.

LLDAP is a lightweight user directory that lets all your self-hosted apps share one set of accounts and passwords. It speaks just enough LDAP for Nextcloud, Jellyfin, Gitea, GitLab, Grafana, Home Assistant, Proxmox VE, Vaultwarden, and many more to authenticate users against a single source of truth, with ready-made example configurations for more than 80 services. Day-to-day administration happens in a web interface where you create users, set passwords, upload avatars, build groups, and add members from a dropdown. Regular users can sign in to edit their own profile, and once SMTP is configured they can request a password-reset link by email instead of pinging the admin. Custom attributes (text, numbers, dates, or JPEG photos) are defined on the user and group schema pages, which unlocks integrations that expect fields such as uidNumber or homeDirectory, including Linux logins through PAM. Three built-in groups keep privileges tidy: lldap_admin for full control, lldap_password_manager for password resets, and lldap_strict_readonly for read-only service accounts. Group membership is exposed through memberOf filters, LDAPS secures connections when you expose the port, and a GraphQL API plus a bootstrap script let you manage users, groups, and attributes declaratively from JSON files. Pair it with Authelia, Authentik, or Keycloak when you also want single sign-on and multi-factor prompts.
