Full Comparison
| Criterion | OutSystems | Rork |
|---|---|---|
| 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 tier; paid from $20 / month Rork Pro $20 / month for 100 credits up to $100 for 500; Rork Max $200 / month for 1,000 credits up to $1,800 for 10,000. Native iOS requires Max. |
| Free trial | Free Personal Edition, no credit card required, for up to 100 internal users | Free tier |
| Commercial use | Not stated | Yes, paid users own the generated code |
| Output | Full-stack enterprise web and mobile applications with data model, server-side logic and UI screens | Native iPhone apps (Swift and SwiftUI), native Android apps (Kotlin and Compose) and web apps (Vite and React) |
| 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 iPhone apps, native Android apps and web apps, plus iPad, Apple Watch and Vision Pro targets on the Max plan |
| 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 | Swift and SwiftUI on iPhone, Kotlin and Compose on Android, Vite and React on the web; Expo and React Native projects can no longer be created, existing ones still build |
| 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 | Rork Cloud, a managed Postgres backend with row-level security and edge functions built on Supabase and transferable to your own Supabase organisation, or connect your own Supabase or Firebase project; sign in with Apple and Google via OAuth |
| Hosting and deploy | OutSystems Cloud with development, testing and production runtimes and a 99.5 percent uptime guarantee, upgradeable to 99.95 percent; extra runtimes and a self-hosted option are advanced add-ons. Built-in CI/CD pipelines with monitoring, tracing and logging | Publish to the Apple App Store, with an AI App Store Reviewer to check a submission first; Google Play via a manually created Android App Bundle; web apps are shared as a link, with no store or review |
| Payments | No checkout of its own; payment providers are integrated through components from the OutSystems Forge, including Stripe connectors for both ODC and OutSystems 11 that handle charges, customers and refunds, and a payments plugin covering Apple Pay, Google Pay and Stripe | RevenueCat for paywalls, in-app purchases, subscriptions and free trials |
| 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 | Paid users own all generated code and download it through a two-way GitHub sync, so it can be edited locally and imported back |
| Deployment | more entries Cloud (SaaS), Browser-based, On-premise | Cloud (SaaS), Browser-based |
| Support | Email helpdesk, Community forum | Email helpdesk, Chat |
| Onboarding | Documentation and knowledge base | Documentation and knowledge base |
| Company size | Enterprise | more entries Freelancers, Small and mid-sized |
| Integrations | Not stated | Supabase, Firebase, RevenueCat, GitHub |

The trade-offs
Strengths and Limitations
OutSystems
Strengths
- Mentor generates a complete application, data model and server logic included, from a requirements document rather than only from a chat prompt
- Shows a visual blueprint and asks for sign-off before applying changes, instead of building unseen
- Runs on containerised .NET Core with Kubernetes, managed Aurora PostgreSQL and built-in CI/CD, monitoring and tracing
- Free Personal Edition for up to 100 internal users needs no credit card
- Self-hosting is available, unlike most tools in this category
Limitations
- No published prices at all, so every evaluation starts with a sales conversation
- Pricing is metered on Application Objects and user counts, which makes cost hard to predict as an app grows
- The Personal Edition is a development runtime only and cannot run production apps
- Self-hosting, 24x7 support, higher uptime and SOC 2 or PCI DSS compliance are all paid add-ons rather than part of the base subscription
- Base support is 8x5 business hours
Rork
Strengths
- Generates genuinely native code, Swift and SwiftUI on iPhone and Kotlin and Compose on Android, rather than a wrapped web view
- Paid users own all generated code, with two-way GitHub sync back into the project
- Rork Cloud gives an app a managed Postgres backend with no setup, and can be moved into your own Supabase organisation later
Limitations
- Native iOS is only on the Max plan, from $200 per month
- The free plan builds web apps only, and projects on it are public
- Google Play publishing is a manual App Bundle upload
- Expo and React Native projects can no longer be created, so a shared codebase for both phones is no longer an option
Plans
