Floorplan

See how your app actually fits together.

Claude or Codex reads your codebase and draws an interactive map of it. Every part, file and web request gets a plain-English name, and every connection between them is shown.

Why Floorplan?

You built an app, probably with a lot of help from AI, and it works. But ask "what happens when someone checks out?" or "what breaks if I change this?" and the honest answer is *no idea*.

Floorplan gives you the diagram nobody drew. Ask Claude Code or Codex for a floorplan and a few minutes later you have a map you can explore, ask questions on, and keep up to date as you work.

- For builders: understand the app you made, in your own words, without reading the code.
- For teams: onboard someone in minutes, from the big picture down to the exact file.
- For working with AI: after every change Claude or Codex makes, see exactly which parts it touched and why.

Floorplan, Archify or Understand Anything?

All three turn code into something you can see, and all three are worth knowing. They answer different questions:

Pick Floorplan to understand and check an app you own. Pick Archify to draw a diagram for a doc, a talk or a decision. Pick Understand Anything to study a large codebase function by function.

They also work together: map your app with Floorplan, then use Archify to draw one flow for a presentation.

How plugins work

  • A plugin bundles slash commands, subagents, skills, hooks, MCP servers and status lines so they install together.
  • Add the marketplace inside Claude Code with /plugin marketplace add haydenschmitty/floorplan, then run /plugin to pick what to install.
  • You can turn a plugin off again from /plugin without deleting anything.
