All Open Source Apps

Open-source ELT platform with 600+ connectors for moving data from any source to warehouses, lakes, and AI agents.

Developer-first error tracking and performance monitoring platform with AI-powered root-cause analysis across 20+ languages and frameworks.

Continuous localization platform that commits translations directly into your version control system with full translator attribution.

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.

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.

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.

The all-in-one open source product platform combining analytics, session replay, feature flags, error tracking, AI observability, and a built-in data warehouse in a single self-hostable stack.

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, 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 reactive Python notebook that eliminates hidden state, runs reproducibly, and deploys as a web app or script — stored as pure Python, built for the AI era.

Open source payments infrastructure that turns software into a business — subscriptions, usage-based billing, digital products, and merchant-of-record compliance in one platform.

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.

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

Compress everything your AI agent reads — tool outputs, logs, RAG chunks, and files — before it reaches the LLM, achieving 60–95% fewer tokens with the same answers.

Secure, fast, and extensible sandbox runtime for AI agents with multi-language SDKs and Docker/Kubernetes runtimes.
