All Open Source Apps

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

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.

Single-executable pixel art editor that starts instantly with no accounts, no setup, and no internet 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.

A self-hostable AI second brain that chats with your documents, searches the web, builds custom agents, and runs entirely on your own LLM.

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

Federated AI search and RAG across 100+ enterprise sources—no data extraction, no vector database required.

Real-time NVIDIA GPU monitoring dashboard — self-hosted, scale from 1 to 100+ GPUs with sub-second metrics and no cloud dependency.

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.

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.

A free, full-featured web-based audio and waveform editor that runs entirely in the browser — no plugins, no installs, just open and edit.

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

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

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.

An open-source, on-device Mac desktop pet that types what you say, takes meeting notes with speaker labels, and talks back — a private alternative to Wispr Flow and Granola.

Self-hostable personal finance app that gives you full ownership of your financial data with a clean, minimal Rails-powered interface.

An MCP server that plugs AI agents into 85+ real-time crypto and finance news feeds, complete with AI impact scores, trading signals, and live WebSocket updates.

Self-hosted, no-code workflow automation that keeps your data on your own servers—a privacy-first alternative to Zapier with 90+ integrations.

A single-file, local-first Kanban board that turns plain Markdown files into a drag-and-drop task manager, with no server, database, or account required.

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

Self-hosted enterprise AI knowledge hub that compiles internal docs into a scoped, reviewable wiki and serves it to Claude and other LLMs through an MCP server.

A local, multi-provider AI coding agent with a real desktop and web UI — bring your own Anthropic, OpenAI, Gemini, Bedrock, or local Ollama keys and let it read, edit, and run code in your own project folder.
