I use Claude Code across multiple projects with different conventions and some shared repos just as it so happens to be the real world. Managing the config files (.claude/rules/, mcps.json, settings.json) by hand got tedious, so I built a local web UI for it.

This one started out as claude-config but migrated to coder-config as I'm adding others (Gemini, AG, Codex, etc).

Main features: - Visual editor for rules, permissions, and MCP servers - Project registry to switch between codebases - "Workstreams" to group related repos (frontend + API + shared libs) with shared context - Auto-load workstreams on cd to included folders - Also supports Gemini CLI and Codex CLI

Install: npm install -g coder-config coder-config ui # UI at http://localhost:3333 coder-config ui install # optionally, autostart on MacOS

It can also be installed as a PWA and live in your taskbar.

Open source, runs locally, no account needed. Feedback and contributions welcome!

Sorry, haven't had any chance to test on other OSes (linux/windows)
