All Open Source Apps

Collaborate on high-quality AI training data with a self-hosted annotation platform built for LLMs, NLP, and multimodal models.

Embed security inside your product — detect threats, fraud, and abuse in real time at the application layer

The lightest self-hosted Linktree alternative — 100+ branded buttons, dark/light themes, and zero JavaScript required.

Rasa Open Source is a Python machine learning framework for building contextual, multi-turn chatbots and voice assistants that understand natural language and maintain conversation state.

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.

Morphik is an AI-native ingestion and retrieval engine that lets developers store, search, and reason over visually rich documents — scanned PDFs, manuals, slides, and video — without duct-taping together OCR, an embedding model, and a vector database.

A visual and textual programming platform for data prep and analysis where the node graph and the underlying Enso code are always perfectly in sync, built by an Alteryx co-founder on a GraalVM engine.

Computer-vision powered Python framework for building RPA bots that click, type, and read any desktop, web, or terminal UI without needing an API.

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.

A 24/7 autonomous AI company: 14 expert-persona agents running on Claude Code or Codex CLI that research, decide, code, deploy, and market real products with a single markdown file as their only memory.

An Apple-Silicon-native LoRA fine-tuning tool for Gemma on text, image, and audio data — with a wizard CLI, live browser-based training visualizer, and streaming from GCS/BigQuery for datasets too large for local disk.

Open source invoicing and billing platform for freelancers and small businesses — create estimates, track expenses, accept Stripe payments, and run recurring invoices from your own server.

Baidu's open-source OCR model for "one-shot, long-horizon parsing" — published with an arXiv paper, a Hugging Face model release, and vLLM inference support, aimed at document understanding beyond typical page-by-page OCR limits.

An open-source build system that turns written specs and architecture into working code — an LLM generates code under tight constraints, task by task with narrow context windows, instead of attempting an entire codebase at once.

Self-hosted email marketing with full data control, multi-workspace isolation, and seamless integration with Amazon SES, SendGrid, Mailgun, and more

A temporal code knowledge graph with blast-radius impact scoring, semantic symbol search, and git-history-aware dependency analysis for AI-assisted development — zero required runtime dependencies, SQLite-backed.

An AI-powered personal news aggregator that filters multi-source feeds through LLMs and delivers curated, noise-free summaries to your Notion workspace.

Self-hosted, open-source Vercel alternative that deploys Python, Node.js, PHP, and any Docker-compatible app from a Git push, with zero-downtime rollouts and real-time logs.

Train a locally hosted AI twin on your own memories—then connect it to the world through a decentralized identity network.

The ultimate open-source steganography suite — hide anything in any file using 100+ encoding techniques, detect it all, and run everything 100% in your browser.

Free open-source AI image upscaler reaching 13K resolution using Stable Diffusion, ControlNet, and Tiled Diffusion — a self-hostable alternative to Magnific.

Give an AI agent a real LLM training setup and let it experiment autonomously overnight — you wake up to a log of experiments and (hopefully) a better model.
