Open Source Developer Tools Apps

High-performance, multiplayer code editor built in Rust by the creators of Atom and Tree-sitter, with native AI integration and real-time collaboration.

An all-in-one JavaScript and TypeScript toolkit — one Rust-and-JavaScriptCore binary that replaces Node.js, npm, a bundler, and a test runner with faster equivalents.

Turn any webpage into a lightweight native desktop app with one command — built on Rust/Tauri instead of Electron, producing installers nearly 20x smaller (typically under 10MB) for macOS, Windows, and Linux.

Open source, self-hostable webhook infrastructure that handles delivery, retries, HMAC signing, and multi-tenant event management so you never have to build a webhooks system from scratch.

Turn scripts into webhooks, workflows, and auto-generated UIs — the fastest self-hostable workflow engine, 13x faster than Airflow.

A fast, secure WebAssembly runtime that runs lightweight containers anywhere — from desktop and cloud to the edge and the browser.

Git, but better — a modern version control client with stacked branches, parallel workflows, unlimited undo, and first-class support for AI-powered development.

OpenAI's open-source CLI coding agent that reads, edits, and runs code in your terminal using natural language prompts.

An open source AI-native proxy that secures, observes, and governs agent-to-LLM, agent-to-tool, and agent-to-agent communication through MCP, A2A, and unified LLM routing.

Embedded KV store built on object storage with zero replication cost

Compose, extend, and observe every backend service in real time using three primitives: Workers, Functions, and Triggers.

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

Stateful actors as a primitive for AI agents, real-time collaboration, and durable execution — with in-memory state, WebSockets, queues, and scheduling built in.

The safe, private runtime that lets autonomous AI agents operate in sandboxed environments governed by declarative YAML policies — blocking data exfiltration, credential leaks, and unauthorized network activity before they happen.

A terminal-native agent multiplexer that runs Claude, Codex, Gemini, and other coding agents side by side in real, persistent panes you can detach from and reattach to from anywhere.
