All Open Source Apps

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

An open-source context database that gives AI agents a unified filesystem for memory, resources, and skills with hierarchical tiered retrieval.

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.

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

All-in-one self-hosted home server with SmartShield anti-DDoS, Nebula mesh VPN, automatic HTTPS, and a 250-app marketplace — all secured behind a unified auth layer.

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

Deploy and scale containerised apps across any servers without Kubernetes or Swarm overhead

Self-hosted, single-tenant group chat with real-time rooms, direct messages, Web Push, and file sharing — no subscriptions, no external services.

Open-source feedback management and roadmap tool that lets product teams collect, prioritize, and respond to user input — with AI-powered summarization and full self-hosting control.

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.

Visual ETL that compiles to Polars — build pipelines on a canvas, export as standalone Python, and run anywhere without platform lock-in.

Transform messy, unstructured documents into persistent, navigable memory that AI agents can actually use.

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.

Redash lets anyone connect to 35+ SQL and NoSQL data sources, write a query in the browser, and turn the result into a shared dashboard — no separate BI suite required.

Fast, stable Redis GUI with cluster, SSH, and massive key support

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.

Open-source, self-hosted alternative to Mailchimp, Brevo, and Klaviyo — send newsletters and transactional emails without per-email pricing or vendor lock-in.

The AI code review agent born at Alibaba's scale — combining deterministic engineering with LLM intelligence for precise, token-efficient reviews.

API-first identity and user management that handles login, registration, MFA, and recovery so your application never has to.

A self-hosted, OpenAI-compatible LLM gateway that puts one endpoint in front of 40+ providers, with virtual API keys, per-user budgets enforced before spend, and full usage tracking.

Open-source, real-time collaborative LaTeX editor with sandboxed compilation and full TeXLive support for self-hosted academic and research teams.

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