This feels like cheating. A developer just open-sourced HolyClaude a single Docker container that gives you Claude Code, a browser-based web UI, 5 AI CLIs, a fully configured headless browser with Playwright, and 50+ dev tools all running with one command. Claude Code, Gemini CLI, OpenAI Codex, Cursor, and TaskMaster AI in the same container, switching between them is one tab press away no other Docker image does this. The setup that used to take 1-2 hours of installing, debugging Chromium crashes, fixing permission issues, and configuring process supervision is now just docker compose up -d and you open your browser. Your existing Claude Max or Pro subscription works out of the box, no extra cost, credentials never leave your machine. 100% Open Source. MIT License.
