Open Source App Cloud Marketplace

A Misago forum comes with threads, polls, private conversations, nested categories, and the moderation tools to keep them in order. Categories nest to any depth. Permissions follow rank, role, and category. Registration can require e-mail activation or administrator approval, and a Q&A challenge, reCAPTCHA, Stop Forum Spam, or an IP blacklist can turn away spam sign-ups. More than 50 OAuth providers, including Google, GitHub, Steam, and Facebook, can handle sign-in. Posts accept GitHub-flavoured Markdown, a BBCode subset, or both, and attachments get thumbnails. Polls allow public or private voters, multiple choices, vote changes, and deadlines. Question threads let one reply be marked as the best answer. A post-accurate read tracker flags threads with new replies. Private threads stay visible only to the people invited. Presence shows who is online, and members can hide their own activity from non-admins. Custom profile fields get their own display and validation rules. Features and settings for GDPR compliance are included. Themes restyle the forum from the admin panel, and plugins extend it through action and filter hooks. Moderators can edit, move, hide, approve, delete, or close content, and a moderation queue holds new submissions for review before other members see them. If someone empties a post, the edit log shows the original wording and can restore it.

Most team chat keeps people in one app and AI agents in another; Octo Server is the backend that puts both in the same conversation. It powers the OCTO workplace, where Lobsters, the platform's OpenClaw-powered AI agents, sit in channels as first-class participants that read context, run tool calls, and report back alongside their human teammates. Every request flows through one pipeline: token and cookie authentication, organisation-aware role checks and per-channel permissions, business logic that can start or resume an agent session, then fan-out through WuKongIM for real-time delivery. Channels support threaded subspaces, shared files, and a GROUP.md document that stores the group's standing context where the whole team can edit it. The smart summary service reads busy channels and produces structured digests, so catching up means reading one brief instead of hundreds of messages. External bridges connect conversations to GitHub, WeCom, Feishu, and Loop through adapters, and webhooks push group events to your own systems. The official one-command deployment runs the server with the web client, admin console, task service, WuKongIM, MySQL, Redis, and MinIO behind nginx, scaling as one backend that every client speaks to.

Ralph tracks thousands of assets across data centers and back offices through a unified CMDB, DCIM, and asset management platform, providing the same capabilities as ServiceNow, Device42, and Sunbird dcTrack without per-asset licensing fees. Used by Allegro in production and backed by over 2,500 GitHub stars, it is built on Python 3 with Django and Django REST Framework. Interactive data center floor plans support drag-and-drop rack placement, front and rear rack views showing U-level asset positioning, power consumption tracking per PDU, and ethernet and fiber connection mapping. The back office module manages laptops, desktops, printers, mobile phones, and accessories with user assignment tracking, warehouse inventory, stock-taking audits, and automated loan workflows. IP address management handles network environments with DHCP and DNS integration alongside network topology visualization. Software license tracking monitors per-user and per-core allocations with usage calculations, compliance reporting, and expiration alerts, while vendor support contracts track SLA agreements and warranty renewal dates. The transitions system automates asset lifecycle processes through configurable workflows that trigger HTTP webhooks, custom Python scripts, email notifications, and Puppet and Ansible configuration management integration. Custom fields extend the data model with text, numbers, dates, choices, and URLs per asset type, accessible via the REST API. Multi-tenant architecture organizes assets by regions, data centers, service environments, and business units. Deploy via Docker with the allegro/ralph image alongside MySQL and Redis.

Track income, recurring expenses, and multi-currency assets with WYGIWYH, a self-hosted personal finance platform built on a strict cash-flow principle that preserves monthly savings while exposing spending patterns. Users can aggregate holdings across checking accounts, physical cash reserves, crypto wallets, and custom asset models with automatic foreign exchange rate calculations. The transaction engine executes automated adjustment rules to normalize merchant names, apply category tags, and calculate split costs on every purchase. Investors can schedule dollar-cost averaging portfolios to monitor accumulation performance and price averages over extended investment horizons. Interactive dashboards provide monthly breakdown grids, calendar views of pending recurring bills, and multi-year net worth trajectories. Financial analysts can export transaction journals to CSV, automate data synchronization through REST webhooks, or query accounts with AI agents via the Model Context Protocol. Customizable notification triggers alert account owners to payment due dates and anomalous spending spikes across monitored accounts.

Write your knowledge as plain Markdown files, and WikiDocs turns the folder into a searchable, versioned wiki with no database to set up or back up. Pages carry YAML front matter, so the whole wiki can be copied, archived, or opened in any text editor. An editor with a formatting toolbar handles headings, lists, task lists, links, and images, and pictures can be pasted straight from the clipboard. Math is typeset with KaTeX, Mermaid renders diagrams such as ER models and mind maps, and code blocks get syntax highlighting. Every save keeps a revision, a versions dialog lists them, and deleted pages wait in a trash where they can be restored or erased. Attachments upload and download from any page, namespaces build a page tree in the sidebar with pinned pages on top, and full-text search highlights every match. Public mode publishes a read-only knowledge base, private mode requires sign-in, and administrator and user accounts are managed in the app. Settings cover the wiki title, owner notice, privacy banner, language, timezone, light or dark template, and accent color, and every page has a print button. A desktop app keeps files on your computer and syncs with your self-hosted instance, while a REST API with Swagger documentation lets other tools read and write pages.

Teams that ship one app in many languages keep every string, translator, and reviewer in a single workspace by hosting their own Traduora translation management platform. Developers import the files they already have: JSON, YAML, PO, XLIFF, CSV, Android XML, iOS Strings, Java properties, PHP array, or RESX. Each string becomes a term that can carry a context note and colored labels. A search bar and a label filter narrow long lists in seconds. Translators open a locale and type inline beside a reference language, with per-locale progress showing how much is finished and a toggle that hides what is already done. Colleagues join by email invitation as admins, editors, or viewers, with optional Google sign-in. Build pipelines get their own API clients, each with a role, to fetch and push translations over a REST API. Exports go back out in whichever format each platform wants, with fallback-locale and untranslated-key options. Mobile and web teams can keep iOS, Android, and website copy in sync from a single source of truth.

Audio lectures become structured, Markdown-formatted notes in about a minute with ScribeWizard (also known as GroqNotes). Upload an MP3, WAV, or M4A file - or paste a YouTube link - and the app runs a three-stage pipeline on Groq's LPU inference hardware: Whisper Large v3 transcribes the audio, a larger Llama model drafts a comprehensive outline of the material, and a faster Llama model fills each section with detailed content. This scaffolded prompting strategy is the core idea: the strong model handles structure where quality matters most, the fast model handles volume, and Groq's 1200+ tokens-per-second inference keeps the whole process near real time. Output renders as clean Markdown with support for tables and code blocks, and finished notes download as text or PDF. Model selection is configurable - swap in other Groq-hosted open models like Mixtral or Gemma to trade speed against quality or work around rate limits. Built as a single Streamlit app by Benjamin Klieger at Groq, it needs only a Groq API key to run, making it one of the simplest self-hosted AI tools to operate.

Podcast enthusiasts and homelab archivers automate digital episode preservation and stream personal audio feeds using PodFetch, an open-source self-hosted podcast manager that combines scheduled RSS downloads, Podcasting 2.0 transcript indexing, and browser playback into a modern listening platform. Listeners can subscribe to international podcast channels through direct feed URLs, Apple Podcasts directory searches, or bulk OPML subscription imports, configuring background polling timers to download new releases automatically upon publication. The integrated audio player supports variable speed playback, episode bookmarks, listening histories, and fullscreen visualization modes directly inside responsive desktop and mobile browser sessions. Advanced search capabilities leverage Podcasting 2.0 synchronized transcripts and automated speech-to-text generation via OpenAI-compatible Whisper APIs, allowing collectors to run full-text keyword searches across every spoken phrase in their audio archive. Built-in GPodder API synchronization maintains subscription lists and playback positions across popular smartphone apps like AntennaPod and native companion clients without relying on commercial cloud accounts. Server operators can assign multi-user accounts with private favorites lists, export customized RSS aggregation streams, and route storage paths between fast solid-state drives and large secondary mechanical hard disks.

Written in optimized C++ where competitors use Python or Java, NZBGet saturates fast connections while idling on CPU and RAM - which is why the performance-obsessed Usenet downloader has long been the client of choice for NAS boxes, Raspberry Pis, and routers as much as full servers. The engineering shows in the recovery pipeline. Instead of shelling out to par2cmdline, NZBGet integrates the par2 source directly and exploits its knowledge of exactly which articles failed - quick par-verification checks only what needs checking, and its own multicore repair implementation runs 2-3x faster than the external tool on the same hardware. Fast par-rename deobfuscates scrambled filenames in seconds without a full verification pass, and rar-rename recovers names for multivolume archives even when no par2 files exist. DirectWrite assembles articles straight into sparse destination files, skipping temporary-file churn entirely, with an article cache and queue-pausing options to eliminate disk contention. Automation is complete: a remote web interface, full JSON-RPC API, RSS feeds with duplicate detection, scheduling and prioritization, and an extension manager for Python and Bash scripts triggered by download events. Sonarr, Radarr, and every major indexer integrate natively.

Usulnet packs container management, Trivy security scanning, Nginx reverse proxy, scheduled backups, WireGuard VPN, firewall rules, and multi-node orchestration into a single 70MB Go binary with zero external runtime dependencies. Every module ships in one download with no paid tiers, no telemetry, and no edition gating. Container lifecycle management covers creation, start, stop, restart, pause, kill, and removal with bulk operations, real-time resource statistics, filesystem browsing, and settings editing. Trivy integration scans images and running containers for CVEs with severity scoring, generates SBOMs, and validates CIS benchmarks. The multi-node architecture supports standalone, master, or agent modes where agents connect over NATS JetStream with mTLS encryption, enabling remote Docker host management from a central dashboard. Reverse proxy configuration handles Nginx with automatic Let's Encrypt certificates, TCP/UDP stream proxying, access lists, and dead host detection. Backup operations capture container volumes and Compose stacks on configurable schedules with retention policies and full restore capabilities. A built-in application catalog provides 60+ one-click templates for common services. JWT license validation uses an RSA-4096 public key embedded in the binary, requiring no call-home and working entirely offline. For teams tired of maintaining separate tools for each infrastructure concern, Usulnet collapses the entire stack into a single point of management with Docker Compose deployment alongside PostgreSQL, Redis, and NATS.

Write the messages today that the people you love would need if you suddenly could not send them, and LastSignal holds them encrypted until silence says it is time. The system emails you a check-in on a schedule you set; answer it and nothing happens, which is exactly the point. Miss one and reminders follow at fixed intervals, and the final reminder can ping a trusted contact who is able to pause the countdown, buying time when a hospital stay or a lost phone is the real story. If nobody responds, your messages are delivered by email to each recipient, who decrypts them with their own passphrase; the server never holds plaintext, so even the person running it cannot read what you wrote. You can stagger access with a per-recipient delay, so one person reads their message the day it arrives while another waits the number of days you chose. Automations can report in through a keep-alive token endpoint instead of email, for machines that prove you are around by staying alive themselves. Timings for check-ins, reminders, and the trusted-contact pause are all configurable per account.

Retrieval-augmented chatbots on your own knowledge base - that is the whole mission of Dialoqbase, an open-source bot-building platform. Feed it content through a broad set of data loaders - web pages and full crawls, sitemaps, PDFs, DOCX, CSV, plain text, GitHub repositories, YouTube videos, and MP3/MP4 audio - and it handles the whole RAG pipeline in one self-contained app: chunking, embedding, vector storage, and LLM querying. The distinguishing architecture choice is PostgreSQL with pgvector for embedding storage and similarity search, which removes the separate vector-database dependency, and Redis-backed Bull queues for ingesting large documents without blocking the API. Model choice is wide open: OpenAI, Anthropic Claude, Google Gemini, Cohere, Fireworks, Hugging Face, local models via Ollama, and any OpenAI-compatible endpoint, with an equally broad list of embedding providers. Finished bots embed on any website with customizable styling or deploy to Telegram, Discord, and WhatsApp, and an API creates and manages bots programmatically. Multi-user support adds registration limits and per-user bot quotas. MIT-licensed and free for commercial use.

100% portability is Nanote's one non-negotiable principle as a self-hosted note-taking app. There is no database - notebooks are plain folders and notes are plain Markdown files on your filesystem, so the same notes remain fully manageable from a terminal, Notepad, or any other editor, and walking away from Nanote costs nothing because your data was never in a proprietary format to begin with. Built with Nuxt and TypeScript around the Milkdown editor, it layers modern conveniences on that plain-file foundation: fast content search across all notes using OS-optimized tooling (ugrep), native Markdown rendering, image and file attachments, and a mobile-friendly layout for reading and editing on a phone. Clever remark directives make plain text interactive - typing ::file inserts an inline upload picker, while ::today, ::now, and ::tomorrow expand to live dates and times. A fully typed REST API with validation covers automation, and access is protected by a configurable secret key. Deployment is one container with three env vars: paths for notes, uploads, and config, all bind-mountable so your Markdown lives wherever you want it - including inside an existing sync setup. AGPL-licensed and actively daily-driven by its author.

RocketplaneIO is a self-hosted AI SRE platform that gives Kubernetes clusters zero-instrumentation eBPF observability plus a copilot capable of safely diagnosing and fixing issues without your telemetry ever leaving your infrastructure. Point it at any cluster, and an eBPF DaemonSet starts capturing HTTP, gRPC, SQL, Redis, and Kafka spans across every service, including compiled binaries, with cross-service context propagation and no code changes required. The live service map draws itself from actual network traffic, matching technology logos from container images and coloring each node's health from RED metrics. Every log line sits two clicks from its parent distributed trace, and a PromQL query engine, embedded from the real Prometheus evaluator, runs over ClickHouse for long-term metric retention. The complete Kubernetes inventory (Services, Ingress, ConfigMaps, network policies, persistent volumes, CRDs) syncs continuously and is searchable alongside traces and logs. When the copilot identifies a problem, it picks from a catalog of roughly 30 risk-classified safe actions; each action verifies its preconditions, captures a before-state snapshot, executes, checks the result, and rolls back automatically on failure. Disruptive operations pause for explicit human approval before proceeding. An MCP endpoint exposes the identical guardrailed toolbox to external AI agents, so Claude Code or Cursor can operate the cluster through the same safety boundary the browser copilot uses. Complex remediations compose as searchable, forkable Starlark workflows that compile deterministically at save.

"Somewhat lightweight, low-friction" is how Silicon Notes' author describes the personal knowledge base - written after DokuWiki's editor "drove me mad" and no existing wiki quite fit. The philosophy is that small frequent annoyances compound into cognitive load with no return, so everything here is optimized for frictionless daily use. Notes are written in plaintext Markdown and rendered as clean HTML with Pygments syntax highlighting for code blocks; pages get bi-directional relationships (backlinks), so the knowledge base becomes a connected web rather than a folder tree; and full-text plus title search retrieves anything fast. A table of contents lives in the left sidebar - "where it belongs" - editable while you read without scrolling away. Page history tracks revisions for auditing and rollback, JSON export/import keeps everything portable, and the mobile layout is genuinely usable. The stack is deliberately minimal: Python and Flask with Mistune for Markdown and SQLite for storage - no big frameworks, just a few small dependencies. One honest caveat: there is no built-in authentication, so deploy it behind a VPN, private network, or reverse-proxy auth layer. For a solo engineer's brain, it is exactly enough.

Every time a commercial book-tracking platform changes its terms or shuts down, years of reading notes and carefully curated wishlists risk getting lost in messy spreadsheet migrations; Jelu puts your entire reading life under your own control as a self-hosted personal Goodreads alternative. Readers log books as currently reading, finished, or dropped, track page progress and dated reading events, and organize titles across unlimited custom shelves using flexible tags. Adding new books takes seconds through mobile camera ISBN barcode scanning, EPUB and OPF metadata extraction, or automated online searches that query Calibre metadata plugins and fallback book providers for covers, summaries, and publisher identifiers. Migrating existing libraries is effortless with bulk imports for Goodreads CSV exports and plain-text ISBN lists alongside one-click CSV data exports. Author pages automatically pull biographies from Wikipedia and include a deduplication tool to merge duplicate author records created during bulk imports. Household and book-club members can sign in via local accounts, LDAP, or reverse-proxy authentication to share book ratings, write public or instance-wide reviews, inspect yearly and monthly reading statistics, and generate HTML or Markdown embed snippets for personal blogs and digital journals.

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.

Before a change lands in the main branch, Review Board gives your team a self-hosted code review server where reviewers read the diff, open issues on specific lines, and sign off with a Ship It. Post a review request from the web or with RBTools, either before you commit or after, and every update becomes a new revision that stays in the history. Interdiffs show exactly what changed between revisions, and moved-code detection keeps rearranged blocks from drowning out real edits. Comments can open issues that reviewers later mark fixed or dropped. Images and Markdown files can be reviewed alongside code, with split, onion-skin, color, and side-by-side diffs for pictures. A dashboard with customizable columns separates incoming from outgoing requests by review group. Connect Git, Mercurial, Subversion, or Perforce repositories, including ones hosted on GitHub or GitLab, and review them all on one server. Slack and Discord notifications, Jenkins builds, and Review Bot linters report back inside the review. Private repositories and hidden or invite-only review groups restrict who sees what, with sign-in through Active Directory, LDAP, or SAML 2.0. A REST API, WebHooks, and Python extensions cover custom workflows. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console.
