All Open Source Apps

Drop your files and search them instantly — no vector DB, no indexing pipeline, just raw data queried by a self-evolving intelligence layer.

A Microsoft-built training framework that optimizes AI agents with reinforcement learning, automatic prompt optimization, or supervised fine-tuning — with near-zero code changes to your existing agent, in any framework.

Give your LLM agents on-the-job training—ART lets you apply GRPO reinforcement learning to any multi-step agentic workflow with minimal code changes.

AI-native PPT generator with Vibe editing, multi-LLM support, and fully editable PPTX export

Self-hosted error tracking that accepts Sentry SDKs out of the box, so you keep your instrumentation and drop the monthly bill.

A pre-indexed code knowledge graph that cuts AI tool calls by 58% and token costs by 16% — auto-syncing, 100% local, works with Claude Code, Cursor, Codex, and more.

A pure-C, zero-dependency inference engine that runs GLM-5.2's 744-billion-parameter mixture-of-experts model on consumer hardware with roughly 25GB of RAM by streaming experts from disk like a JIT compiler stages hot code.

Instant, concurrent, hardware-isolated MicroVM sandboxes for AI agents — E2B-API compatible, sub-60ms cold starts, and a built-in zero-trust egress proxy, all self-hostable at scale.

Open source Ruby on Rails platform for building developer communities with articles, discussions, and social profiles—the same software that powers dev.to.

Developer-oriented health dashboard with active endpoint probing, multi-protocol checks, and 40+ alerting integrations so you know about failures before your users do.

Fast, native, feature-rich terminal emulator with GPU acceleration and an embeddable libghostty library for building custom terminals

A YC-backed, open-source knowledge graph skill for AI coding assistants — type /graphify and it maps your entire project (code, docs, PDFs, images, videos) into a queryable graph instead of grepping through files.

A free, open source procedural 2D design tool that unifies vector, raster, motion graphics, and generative art in a single node-based nondestructive workflow.

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.

Open-source Webhooks-as-a-Service: deliver events to your users with auto-retry, signed payloads, and a real-time subscriber dashboard — all without building the infrastructure yourself.

Turn plain HTML and CSS into deterministic, pixel-perfect MP4 videos — authored by humans or AI agents, rendered by headless Chrome and FFmpeg.

The self-hosted job search assistant that tracks applications, reviews resumes with AI, and auto-discovers matching roles from Greenhouse, Lever, and Ashby boards — all while keeping your data on your own server.

The official Lark/Feishu CLI tool built for both humans and AI agents, delivering 200+ commands and 26 AI agent skills across 18 business domains from messaging and calendar to docs, sheets, and approvals.

Self-hosted photo library with AI-powered face recognition, semantic search, and automatic event albums — no cloud required.

Build high-performance server-rendered web apps with a visual editor, formula engine, and self-hostable backend — all in TypeScript.

An open-source design editor that reads native Figma files, ships a built-in AI assistant with 100+ design tools, and offers real-time serverless collaboration — all without giving up your files.

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.

Openship is an open-source, self-hostable deployment platform that points at a repo and builds, ships, routes, and TLS-terminates the app — driven from a desktop app, web dashboard, or CLI.

An open-source Agent Development Environment that orchestrates fleets of parallel AI coding agents — Claude Code, Codex, Gemini and more — each running in its own isolated git worktree.
