# Floorplan — AI Coding Tool Review & Pricing

> Open-source Claude Code and Codex plugin that has your coding agent read a codebase (one repo or several) and draw a local, interactive, plain-English map of its parts, files, endpoints, screens and outside services, with an Ask bar, recent-change highlights and a security-focused Health check.

## At a glance

- **Tool**: Floorplan
- **Company**: Hayden Smith
- **Category**: [AI Codebase Knowledge & Generation](https://ai.dosa.dev/category/codebase-ai)
- **Pricing model**: Free
- **Official website**: https://github.com/haydenschmitty/floorplan

## Key features

- Zoomable map from whole app down to files and endpoints
- Matches frontend web requests to server endpoints, even across repos
- Ask the map: answers with a mini-map and step-by-step walkthrough
- Recent work view highlights what the agent just changed and why
- Health check for leaked keys, open Supabase/Firebase rules, fakeable Stripe webhooks and unauthenticated endpoints
- Blueprints that plan an unbuilt app from a PRD or spec
- Runs locally with zero dependencies; exports a single HTML file

## Pricing

**Model**: Free

Free and open-source (MIT). Runs on your existing Claude Code or Codex plan with no API keys and no paid tier.

## Who it is for

- **Best for**: Builders and teams using Claude Code or Codex who want a plain-English architecture map of an AI-built app, faster onboarding, and a quick check for common security mistakes.
- **Not ideal for**: Developers who need function-level knowledge graphs of very large codebases, formal security audits, or support for agents other than Claude Code and Codex.

## Verdict

A fast-moving, privacy-friendly way to see how an agent-built app fits together; its Health check is a useful first pass, not an audit, and it is limited to Claude Code and Codex for now.

## Recent updates

v0.6.3 (Nov 2, 2026) added route-table endpoints, full Fastify and Django endpoint prefixes and a parsing fix; v0.6.0-0.6.2 added AI-app Health checks and far fewer false alarms with a Not a problem button.
