#open-source

SDD ObservatoryNew

Open, community-maintained directory tracking spec-driven development frameworks and real-world projects to evaluate their practical effectiveness.

Blender Agent BridgeNew

Free, open-source Blender extension that lets AI coding agents like Claude, Cursor, and Codex safely inspect and edit 3D scenes with reversible changes and visual proof of what they did.

restoredrillNew

Automatically restores your latest PostgreSQL backup into a throwaway container and proves it actually works, with an audit-ready report.

Apron AgentsNew

Local orchestrator that splits a coding task into independent issues and runs each on a sandboxed AI worker agent, with a dashboard for staged merge review.

iCloud Keychain for LinuxNew

Unofficial client that brings iCloud Keychain passwords to Linux, with a browser extension for autofill.

Orchesty

Open-source streaming-first integration platform for building scalable asynchronous workflows and orchestrating APIs with AI agent support.

Open-Generative-AI

A free, self-hosted AI image and video generation studio with 500+ models and no content filters, giving you the same generation power as paid platforms like Midjourney or Runway without a subscription or a company deciding what you're allowed to prompt.

beUI

A free, open-source library of 109 animated UI components for React and Next.js, built with Motion and Tailwind CSS, distributed as copy-paste source via the shadcn CLI.

MeshLAN

A self-hosted virtual LAN for Windows that creates encrypted peer-to-peer links between devices on different networks, with stable DNS names, file transfer, and a live network map — a free, self-run alternative to Tailscale.

OpenMausBot

An open-source, local-first messaging app that lets you run and chat with multiple AI agents as contacts, each backed by a different model, with access to 500+ app integrations and cloud desktops.

MCP State Twin

A testing framework that gives AI agents deterministic, forkable, stateful sandboxes — so you can run the same starting state through different tool-call sequences and compare results reproducibly.

Open Analytics

A cookieless, privacy-first web analytics platform with Stripe revenue attribution and an AI chat interface for querying your stats in plain English — open source and self-hostable, or hosted at getopen.so.

HFlow

An open-source SDK for building robotics data pipelines, managing the collection-to-delivery lifecycle of multimodal sensor data with quality checks and full provenance tracking, backed by Y Combinator.

Entire

A checkpoint system for AI coding agents that pairs every Git commit with the full agent conversation that produced it, so teams can search, review, and resume work across Claude Code, Copilot, or Cursor.

LivelyIcons

A free React icon library with over 1,300 animated icons and 14 distinct animation styles.

Its Hover

An open-source library of 186+ animated icon components for React, with motion baked into every hover.

HyperDX

A free, open-source observability platform that unifies logs, metrics, traces, errors and session replays in one searchable interface — a self-hosted alternative to Datadog.

LangGraph for Swift

A free, open-source Swift library that brings LangGraph's stateful, multi-step AI agent pattern natively to iOS and macOS development, without needing a separate Python backend.

Plain

A Python web framework that grew out of a real company's Django app, built explicitly so AI coding assistants (and humans) can understand and safely modify the code.

PostgresAI

AI-native Postgres observability: 45+ automated health checks, query and config tuning, agent-ready JSON and MCP output. Open source.
