See what you're
really building.
Mapparoo turns planning documents and a codebase into an honest, visual map: what was promised, what actually got built, and the gap between the two. Whether the code comes from an AI agent, a dev shop, or someone before you — you shouldn't have to read it to understand it.

The problem
Software is a system.
What you can see is a pile of parts.
Any real project is more complex than it looks: sprawling documents on one side, an accumulating codebase on the other, and the actual design — how everything connects — visible in neither. Skimming the docs won't reveal it. Scanning the code won't either. And that's before asking whether any of it does what was promised.
The design is buried in the documents
Requirements, designs, task lists — promises scattered across a document set no one can hold in one head, drifting further from the build every day.
The connections are invisible
How the pieces actually depend on each other isn't written down anywhere — it emerges. The connection you didn't know existed is the one that breaks.
"Done" is a claim, not a fact
A checked checkbox, an agent's summary, a contractor's status report — all claims. If you can't read the code, you can't check any of them.
What you get
A map for every moment of needing to know.
"Show me what we're building."
The Plan guide — free to start.
Your planning documents, turned into a visual guide anyone can follow: the pieces, how they connect, what the plan promises. Finally see your own plan whole — before money rides on it.
"What is this, really?"
Discovery — for inherited code.
Bought a micro-SaaS? Taking over a contractor's handoff? Discovery starts from the code alone and maps what's actually there. It never pretends to know what was intended — and it gives you a route to a real audit.
"Did I get what was promised?"
The Audit — plan vs. build.
The full comparison, whoever wrote the code — your agent or your agency: what's built and verified, what's present but unproven, what's missing, what showed up unplanned. Each finding pinned to evidence, ending in a decision you can act on.

Who it's for
If any of these is you, you've felt this.
The founder-builder
You're shipping a real product with Claude Code, Cursor, or Lovable. Customers, money, or your name will be attached — and you need to know what you actually have before they are.
Learn more →The commissioner
You're paying a freelancer, an agency, or a technical cofounder to build it. You want to understand what you're getting, measure it against what was agreed, and walk into every check-in with more than a feeling.
Learn more →The plan-first builder
You work spec-first — Kiro, Spec Kit, or your own document system — and the docs have outgrown your ability to re-read them. You want the plan itself made legible, then held up against the build.
The inheritor
You bought a micro-SaaS, took over a contractor's handoff, or inherited a cofounder's repo. The docs are stale or missing. You need to know what this thing really is before you build on it.
