Your stack. Your rules.
The open-source, cross-platform desktop app that bootstraps your complete self-hosted AI and developer infrastructure — in minutes, not days.
Think: Homebrew meets Docker Desktop meets an AI-native App Store.
OpenTang is a guided desktop installer that takes you from zero to a fully running self-hosted AI and developer stack. No YAML wrangling. No terminal gymnastics. Just pick what you want, click install, and go.
It handles Docker orchestration, credential generation, SSL configuration, and service health — all through a clean, step-by-step wizard with an orange-fire dark UI.
Built for:
- Developers setting up a personal AI/dev environment
- Self-hosters who know Docker but hate config sprawl
- Teams bootstrapping shared infrastructure
- Anyone who wants local LLMs + AI agents running in minutes
- 🧙 Step-by-step wizard — guided setup from system check to running services
- 🤖 AI-first — install OpenClaw, Hermes, or NanoClaw with one click
- 🧠 Local or cloud LLM — bundle Ollama for local models, or bring your own OpenAI/Anthropic key
- 🐳 Docker-powered — everything runs in containers, managed by Compose
- 🔒 Secure by default — auto-generated strong passwords, Traefik + Let's Encrypt SSL
- 📦 In-app store — install, update, and remove services after initial setup
- 🌐 Any network mode — localhost, LAN, or internet-facing with auto SSL
- 🖥️ Cross-platform — Windows (WSL2), macOS (Intel + Apple Silicon), Linux
- 🔄 Auto-updates — app and package registry update independently
