Exotool vs Bubble
Bubble is the best-known no-code web app builder: a visual editor, a workflow engine and hosting in one product. Exotool starts from the same wish, a working app without writing code, and answers it differently: you design the app as a diagram, and Exotool's engine generates the whole stack as source you own.
Side by side
| Bubble | Exotool | |
|---|---|---|
| What describes the app | Pages, workflows and a database schema, edited visually in Bubble's editor. | One diagram: the screens, how they connect, and the activities behind them. |
| How the app is made | Bubble interprets your design at run time, on Bubble's platform. | A patented engine generates the device side, the server side and the APIs between them, the same way every time. |
| Where it runs | On Bubble's hosting. Enterprise plans offer a choice of hosting location. | In Exotool's sandbox while you build; then on any web-capable hosting platform you choose. |
| The source code | Not exportable: a Bubble app runs only on Bubble. | Yours. Exotool gives you the generated code; deploy it where you want. |
| Your data | In Bubble's database, on Bubble. | In your own database, with the app, wherever you run it. |
| Leaving | The app stays behind. | Take the code and the database with you. No lock-in. |
| AI | An AI build assistant inside Bubble's editor. | Claude builds and changes the app through the Exotool connector; you see every change in the diagram. |
| Native mobile | Yes: native mobile apps on React Native (paid plans publish them). | 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 | Bubble's server checks privacy rules; by Bubble's own documentation, a data type with no rule is readable by everyone, and the Data API can expose tables directly. | Reached only from the server side the engine generated; the browser is never given a database key. |
| Pricing (published October 2026) | Free (development only, 50K workload units a month); Starter $59, Growth $209, Team $549 a month, billed annually. | Free (one app); Basic $19 a month (three apps); Pro $49 a month (unlimited). No usage units. |

Where Bubble is the better choice
- You want native iOS and Android apps built and published from one editor.
- You rely on Bubble's plugin marketplace and its large community of templates and agencies.
- You prefer a fully managed platform and never intend to host anything yourself.
Where Exotool is the better choice
- You want to own the code and the database, and to run the app on your own host without a per-month platform fee that grows with usage.
- You want Claude to build and change the app, and to see exactly what it changed, in one diagram rather than in thousands of lines.
- You want the same input to produce the same app every time: an engine, not a model, writes the code.
