All Open Source Apps

A free and open source football management simulation game built with Rust and Tauri, inspired by Football Manager.

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

Open-source enterprise data warehouse unifying analytics, vector search, full-text search, and AI agent orchestration in a single Rust-built engine on S3.

Open-source, self-hosted remote desktop built in Rust — your data, your infrastructure, no third-party cloud.

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 vector database and search engine built in Rust for production-grade AI applications — from semantic search to RAG pipelines and recommendation systems.

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.

Open-source, embedded vector database built on the Lance columnar format for fast multimodal search across billions of vectors, backed by Y Combinator (W23).

Lightning-fast hybrid search engine with AI-powered semantic and full-text retrieval for modern applications.

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

Open source Loom alternative with GPU-accelerated recording, instant share links, AI summaries, and full self-hosting via Docker Compose.

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

Federated, self-hosted Reddit alternative with full community ownership and no corporate control.

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

All-in-one secure mail and collaboration server covering IMAP, JMAP, SMTP, CalDAV, CardDAV, and WebDAV in a single memory-safe Rust binary.

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.

Born out of Y Combinator's S2023 batch, ParadeDB is a Postgres extension that delivers Elasticsearch-quality BM25 search and real-time analytics without a separate search cluster to manage.

Cloud-native search engine for logs and traces, delivering sub-second search directly on S3, GCS, or Azure Blob storage at a fraction of Elasticsearch's cost.

Embedded KV store built on object storage with zero replication cost

Fast, lightweight, schema-less search backend in Rust — microsecond queries, 30MB RAM, no document storage required.

Unofficial Bitwarden-compatible server in Rust — run the full Bitwarden ecosystem on a Raspberry Pi using every official client you already have, without the multi-container overhead.

A distributed stream processing engine written in Rust that lets you write SQL to run stateful, real-time computations over data streams with subsecond results.
