Cataleo does not name a winner. Both statements come from the vendors themselves.
| Criterion | OutSystems | Thunkable |
|---|---|---|
| Starting price | Free Personal Edition; OutSystems Developer Cloud quoted by the vendor ODC is metered on three things: application complexity in Application Objects, which is the sum of screens, database tables and API methods, with a typical medium app around 150 AOs; the number of internal and external end users; and advanced add-ons. A base subscription starts with one medium production application and 100 internal users. | Free plan; paid from $18 / month Billed yearly; billed monthly the same plans cost $19, $59 and $189. Every plan carries a monthly AI token allowance, from 2,000 on Free to 100,000 on Advanced. Enterprise and education plans are quoted on request. |
| Free trial | Free Personal Edition, no credit card required, for up to 100 internal users | Free plan with 3 public projects, 5 screens per project and no published apps |
| Output | Full-stack enterprise web and mobile applications with data model, server-side logic and UI screens | Native iOS and Android apps plus web apps, published from one project |
| API | Yes, API-first with CI/CD APIs and APIs for uploading external libraries | Not stated |
| Hosting | OutSystems Cloud on AWS; self-hosting is available as an advanced add-on | Not stated |
| What it generates | Full-stack enterprise applications: Mentor generates the data model, server-side logic and UI screens from a natural language prompt or an uploaded requirements document, shows a visual blueprint before building, and then evolves the app through conversation inside the IDE with human sign-off on each implementation plan | Native iOS and Android apps plus web apps, generated from a written description by the AI Builder and then editable screen by screen |
| Stack and frameworks | .NET Core on Linux containers, each application isolated in its own container, orchestrated with Kubernetes on AWS; developers extend apps with custom .NET code uploaded as high-code external libraries, whose methods are exposed to the visual editor as server actions | Drag-and-drop designer with blocks, plus a built-in code editor for direct edits alongside the AI |
| Auth and database | Amazon Aurora Serverless with PostgreSQL compatibility as the managed database; ISO 27001 compliance is included and SOC 2 Type II and PCI DSS are advanced add-ons | Local tables, Google Sheets, Airtable, Webflow, the Firebase Realtime Database and Cloudinary; user sign-in through the Firebase Authentication REST API |

Built-in CI/CD pipelines with monitoring, tracing and logging | Published from the platform to the Apple App Store, Google Play and the web on a custom domain, with TestFlight for iOS beta builds |

| Access to the code | Applications are built visually rather than in a repository of hand-written source; custom C# and .NET logic enters as external libraries uploaded through the SDK and APIs, decorated so their methods surface as server actions | Compiled builds rather than a repository: downloading an Android app sends an APK by email, and publishing sends an AAB to upload to the Play Store. No source-code export or Git sync is documented, so edits stay in the builder |
