Overview
Floorplan is a plugin for Claude Code and Codex that scans a repo or several repos and builds a zoomable map of parts, files, endpoints and screens, with plain-English names. It matches frontend requests to server endpoints, also across repos, and adds a Health check for common mistakes such as committed keys and open Supabase tables. The map is a local HTML file, and updates re-read only changed files.
Who it is for: Developers using Claude Code or Codex who want to understand AI-built apps
Strengths
- Matches frontend requests to backend endpoints across separate repos
- Zero dependencies and no install scripts; scan and map server run locally
- Incremental updates re-read only changed files; 'Recent work' highlights what the agent edited
- Runs on your existing Claude or ChatGPT plan with no API keys
Weaknesses
- Requires Claude Code or Codex; no standalone use outside an agent session by default
- First map on a large project takes a while, since every file is described by the model
- Health check is a basic check, not a security audit
- Names and descriptions are model-written and may need manual renaming
What it needs
- no GPU
- Needs Node.js 18+, Claude Code or Codex
- Models: Claude (via Claude Code), OpenAI models (via Codex)
Quick answers
