Exotool vs FlutterFlow
FlutterFlow is a visual builder for Flutter apps: you lay out screens on a canvas, wire them to Firebase or Supabase, and download the Flutter project or publish to the app stores. Exotool builds a different thing from a different input: a full-stack progressive web app, server side included, generated by an engine from one diagram.
Side by side
| FlutterFlow | Exotool | |
|---|---|---|
| What describes the app | Screens on a canvas, with actions and queries, in FlutterFlow's editor. | One diagram: the screens, how they connect, and the activities behind them. |
| What is built | A Flutter front end (mobile, web, desktop); the back end is Firebase, Supabase or your own API. | The front end, the server side and the APIs between them, from the same diagram. |
| How it is built | Generated Flutter code from the canvas. | A patented engine generates the device side, the server side and the APIs between them, the same way every time. |
| Where it runs | The app where you publish it; the data on Firebase or Supabase. | In Exotool's sandbox while you build; then on any web-capable hosting platform you choose. |
| The source code | Downloadable on Basic and above; GitHub integration on Growth and above. | Yours. Exotool gives you the generated code; deploy it where you want. |
| Your data | On Firebase or Supabase, or behind your own API. | In your own database, with the app. |
| Leaving | You keep the Flutter code; the back-end services are the providers'. | Take the code and the database with you. No lock-in. |
| AI | AI generation requests inside the editor (a lifetime allowance on Free). | Claude builds and changes the app through the Exotool connector; you see every change in the diagram. |
| Phones and tablets | Native iOS and Android builds, published to the stores from the platform. | A progressive web app that runs on iOS and Android alike, installed from the browser; no app-store build. Native iOS apps: in beta. |
| The database | Through the Firebase or Supabase client SDK, with the provider's security rules or policies as the guard. | Reached only from the server side the engine generated; the browser is never given a database key. |
| Pricing (published October 2026) | Free (2 projects, 5 AI generations in all); Basic $39 a month (code and APK download); Growth $80 a month for the first seat; Business $150 a month for the first seat. | Free (one app); Basic $19 a month (three apps); Pro $49 a month (unlimited). Per builder, nothing metered. |

Where FlutterFlow is the better choice
- You need native iOS and Android apps in the stores, built from one Flutter codebase.
- You already run Firebase or Supabase and want the app wired to them.
- You want pixel-level control of a native UI on a canvas.
Where Exotool is the better choice
- You want the server side generated too, not assembled from a backend service.
- You want Claude to build and change the app and the diagram to show what changed.
- You want to own the back end and run it where you choose.
