All Open Source Apps

Open source AI gateway and Python SDK that gives you one OpenAI-compatible interface to call 100+ LLM providers, with built-in routing, cost tracking, guardrails, and virtual keys.

Open-source feature flagging, remote config, and A/B/multivariate testing platform for web, mobile, and server-side apps — self-host or use the hosted SaaS.

Open-source cron job and background task monitoring that alerts you when your scheduled jobs go silent.

Build, test, and deploy AI agents and RAG workflows visually with native API and MCP server export.

Self-hosted web archiving that saves HTML, PDFs, screenshots, media, and code in open formats you own forever

The batteries-included Python agent harness — planning, sub-agents, filesystem, shell, memory, and skills bundled in, built on LangGraph.

Open-source collaborative knowledge platform with real-time editing, AI writing tools, and full self-hosting control — built by the French and German governments.

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

Turn messy real-world dataframes into machine learning features — no manual wrangling required.

Chromium without Google tracking — privacy-focused, drop-in replacement

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

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.

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

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

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.

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.

A keyboard-driven terminal dashboard for managing cron jobs on local machines and remote servers via SSH.

An all-in-one open-source training suite for finetuning diffusion models—FLUX, SDXL, Wan video, and audio—on consumer GPU hardware via CLI or web UI.

A next-generation documentation site generator for dbt Core projects — lineage explorer, health scoring, and full-text search for teams without access to dbt Cloud's built-in docs features.

A stealth Chromium engine that corrects the browser fingerprint inside the C++ engine itself, so scrapers and browser agents stop getting blocked, with a 29-tool MCP server for AI agents.

Self-hosted private cloud storage with AI semantic search and a pluggable multi-backend file management system.

An MCP server giving AI agents real, undetectable browser automation — built on nodriver and Chrome DevTools Protocol to navigate sites protected by Cloudflare and other anti-bot systems for automation and testing workflows.

A fully local web research assistant that iteratively searches, summarizes, and refines markdown reports using any Ollama or LMStudio model—no cloud or API keys required.

Build autonomous and human-in-the-loop multi-agent AI systems with a layered, event-driven Python and .NET framework pioneered at Microsoft Research.
