All Open Source Apps

The painless self-hosted Git service that runs on anything from a Raspberry Pi to a $5 cloud droplet, delivering GitHub-like workflows as a single Go binary.

Free, offline, open-source speech-to-text that pastes directly into any app on Windows, macOS, and Linux.

The programmable open source core ledger for fintech — build money-moving applications with atomic multi-posting transactions, account-based modeling, and Numscript, a built-in DSL for financial logic.

Detect malicious network traffic using 47+ live threat feeds, heuristics, and a fat-client reporting dashboard — no commercial stack required.

Run LLM-generated Python code safely inside your agent—no containers, no CPython, no compromise—with sub-microsecond startup.

An open-source MCP platform for organizations — host MCP servers, run MCP registries, monitor usage, and build agents and chatbots on top of the Model Context Protocol from one self-hosted deployment.

The open-source, offline-first Notion, Obsidian & Confluence alternative with multi-tenant teams, OIDC/SSO, and one-command Docker deployment.

A Microsoft-built training framework that optimizes AI agents with reinforcement learning, automatic prompt optimization, or supervised fine-tuning — with near-zero code changes to your existing agent, in any framework.

A production-ready 2D/3D game engine written in Rust with a built-in scene editor, physics, and hot-reloading game scripts

A wire-protocol gateway that enforces data masking, command blocking, approval workflows, and full session recording for engineers and AI agents accessing production infrastructure.

Privacy-first AI meeting assistant that transcribes and summarizes your meetings entirely on your local machine — no cloud, no data leakage.

The official Lark/Feishu CLI tool built for both humans and AI agents, delivering 200+ commands and 26 AI agent skills across 18 business domains from messaging and calendar to docs, sheets, and approvals.

Local-first AI memory with verbatim storage, pluggable backends, and 96.6% retrieval recall on LongMemEval — no API key required.

Open-source flat-file CMS for publishing Markdown-based documentation, manuals, and eBooks without a database.

Self-hosted, single-tenant group chat with real-time rooms, direct messages, Web Push, and file sharing — no subscriptions, no external services.

Automate SSL certificate lifecycle across any CA, 24+ DNS providers, and every major secret store — with a REST API, web dashboard, and built-in MCP server for AI-driven ops.

Visual ETL that compiles to Polars — build pipelines on a canvas, export as standalone Python, and run anywhere without platform lock-in.

A YC-backed, open-source knowledge graph skill for AI coding assistants — type /graphify and it maps your entire project (code, docs, PDFs, images, videos) into a queryable graph instead of grepping through files.

Self-hosted photo library with AI-powered face recognition, semantic search, and automatic event albums — no cloud required.

Define AI agent workflows as code graphs, route tasks across any LLM, and intervene only where it matters.

Fast, stable Redis GUI with cluster, SSH, and massive key support

An open-source, AI-native vector design tool with concurrent agent teams, design-as-code, a built-in MCP server, and multi-model intelligence — a distinct project from the similarly-named Figma-file-reading "open-pencil" editor.

A self-hosted document management system that OCRs, indexes, and makes every PDF, scan, and Office file instantly searchable.

A single graph+vector+temporal database for AI workloads — Neo4j-compatible, sub-millisecond hybrid search, and built-in memory decay.
