Exotool vs Mendix
Mendix is a Siemens enterprise low-code platform: model-driven apps, deployed to Mendix Cloud, a private cloud or your own servers on paid plans, priced per app and per user. Exotool is the small team's answer to the same need: one diagram, a patented engine that generates the whole stack, the source in your hands, and plans from free to $49 a month with no charge per user of the app.
Side by side
| Mendix | Exotool | |
|---|---|---|
| Who it is priced for | Enterprises: Standard from $1,090 a month for one app or $2,725 for unlimited apps, plus per-user fees (anonymous users free); Premium by quote; cloud compute extra. | Builders: Free, Basic $19, Pro $49 a month; nothing per user of the app. |
| What describes the app | Domain models, pages and microflows in Mendix Studio Pro. | One diagram: the screens, how they connect, and the activities behind them. |
| How it is built | Model-driven, run by the Mendix runtime. | A patented engine generates the device side, the server side and the APIs between them, the same way every time. |
| Where it runs | Mendix Cloud on Free; private cloud (Kubernetes), SAP BTP or your own servers on paid plans. | In Exotool's sandbox while you build; then on any web-capable hosting platform you choose. |
| The source code | Not stated as exportable; the model runs on the Mendix runtime. | Yours. Exotool gives you the generated code; deploy it where you want. |
| Leaving | The app needs the Mendix runtime wherever it goes. | Take the code and the database with you. No lock-in. |
| AI | AI assistants in Studio Pro (Maia). | Claude builds and changes the app through the Exotool connector; you see every change in the diagram. |
| Phones and tablets | Native and progressive mobile apps 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. |
| Pricing (published October 2026) | Free (Mendix Cloud only, one environment per app, unlimited users); Standard from $1,090 a month; Premium by quote. | Free (one app); Basic $19 a month (three apps); Pro $49 a month (unlimited). Per builder, nothing metered. |

Where Mendix is the better choice
- You are an enterprise standardising on one platform with governance, high availability and multi-region failover.
- You need SAP BTP or a private Kubernetes deployment with vendor support.
- You have a team of professional developers who want a model-driven IDE.
Where Exotool is the better choice
- You are a small team or a single builder and $1,090 a month for one app is out of scale.
- You want the generated source and your own database, free of a runtime.
- You want Claude to build and change the app, with the diagram showing what changed.
