Exotool vs OutSystems
OutSystems is the enterprise low-code platform: a managed cloud or on-premises runtime, priced by quote on the size of the apps and the number of end users, with a free Personal Edition to learn on. Exotool is the small team's answer to the same need, a whole stack without hand-written code: one diagram, a patented engine, the generated source in your hands, and plans from free to $49 a month with no charge per user of the app.
Side by side
| OutSystems | Exotool | |
|---|---|---|
| Who it is priced for | Enterprises: subscriptions depend on application objects (a medium app is about 150) and on the number of internal and external end users. | Builders: Free, Basic $19, Pro $49 a month; nothing per user of the app. |
| What describes the app | Modules, screens, data and logic in Service Studio. | One diagram: the screens, how they connect, and the activities behind them. |
| How it is built | Generated standard code, run by the OutSystems platform in its cloud, a private cloud or on premises. | A patented engine generates the device side, the server side and the APIs between them, the same way every time. |
| Where it runs | OutSystems Cloud (the Personal Edition only there); self-hosting in certain plans. | In Exotool's sandbox while you build; then on any web-capable hosting platform you choose. |
| The source code | Described as standard, open code that can be extended; export and running outside the platform are a matter for sales. | Yours. Exotool gives you the generated code; deploy it where you want. |
| Leaving | Ask sales. | Take the code and the database with you. No lock-in. |
| AI | AI across the platform (agentic systems). | Claude builds and changes the app through the Exotool connector; you see every change in the diagram. |
| Phones and tablets | Mobile apps generated by 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) | By quote; a free Personal Edition (development runtime, up to 100 internal users, OutSystems Cloud). | Free (one app); Basic $19 a month (three apps); Pro $49 a month (unlimited). Per builder, nothing metered. |

Where OutSystems is the better choice
- You are an enterprise with hundreds of internal users, compliance add-ons and a platform team.
- You need on-premises or sovereign hosting with a vendor's support behind it.
- You are standardising many departments on one low-code platform.
Where Exotool is the better choice
- You are a small team or a single builder and the quote-based model does not fit.
- You want to own the code and the data from day one and run the app anywhere.
- You want Claude to build and change the app, with the diagram showing what changed.
