See how your app is built, even if AI wrote it. Every screen, API, table and service on one map — and what each change affects before you push or pull.
Works with Next.js + Supabase · Chrome, Edge, Brave, Arc (Safari & Firefox in snapshot mode)
Cursor, Claude and Lovable ship features in minutes. Understanding what they built — and what breaks when you change it — still takes hours.
Fifty files later, you can’t tell which screen calls which API, or which table it writes to.
A one-line prompt touched twelve files. Which features did it actually affect?
A teammate added a table, a secret and a package. Nobody told you.
Kartta reads your project and groups it the way you think about it: Orders, Menu, Billing. Click one to see the whole flow.
Click any table, API or file and Kartta shows every screen and feature that depends on it.
See every commit, push and pull — and which features each one touched. Then get told exactly what to do.

Pick your project in the browser. Kartta reads it right there — nothing is uploaded.
Features, flows, impact. It refreshes as your AI edits code.
Run npx kartta to see uncommitted changes and the Bridge, live.
Your code is analyzed on your computer, never uploaded.
Kartta never edits code, pushes or pulls.
It reads env variable names, never their values.
The local helper only talks to Kartta, with a one-time code.

No. When you open a folder, Kartta analyzes it inside your browser. The local helper (npx kartta) runs on your computer and only shares names and structure with the Kartta page you paired it with. Your code never reaches our servers.
Today Kartta is built for Next.js (App Router and Pages Router) with Supabase — the most common stack for vibe-coded apps. It also detects 30+ services like Stripe, Resend, OpenAI and Google. More frameworks are coming.
No. Kartta is made for people who build with AI. It explains your app in features and screens, and tells you what to test before you push.
Never. Kartta is read-only: it doesn’t edit files, commit, push or pull. It only tells you what’s happening and what to check.
Yes — it works with any editor or AI tool, because it reads the project folder itself. The map updates as the AI edits your files.
Chrome, Edge, Brave and Arc get live updates and the Git connection. Safari and Firefox can open a project as a snapshot.
