Move off OutSystems without rebuilding from scratch.
Extract your business logic, migrate to a modern stack, and reduce platform dependency without disrupting operations.
When It's Time to Move Beyond OutSystems
OutSystems Makes Application Growth More Expensive
Adding screens, entities, and APIs increases your Application Object count. Once your estate reaches its licensed AO capacity, expanding it can mean increasing your OutSystems license. Your software grows, and your platform commitment grows with it.
Your Licensing Model Is Driving Technical Decisions
Objects are priced in blocks, if you cross a threshold then costs escalate. Your teams start merging screens, reusing tables, and making design compromises to stay under the limit. The bills start deciding how the application is built.
Your OutSystems Estate Is Holding Back AI Productivity
Modern AI coding tools work best with code they can read, search and reason over. Your OutSystems applications are represented primarily through a proprietary visual model, limiting how effectively those tools can work.
OutSystems Limits Your Talent Pool
Finding experienced OutSystems developers is difficult and expensive. You are hiring from a small pool of specialists instead of the much larger mainstream software engineering market.
How the Rewrite Works
Undocumented business logic is scattered across every layer of your legacy estate. SNAP™, our orchestration layer for AI-native engineering, captures that context and turns it into a precise specification. Our engineers resolve edge cases and sign off the PRD with your team. Once approved, we build the new application and prove functional and non-functional parity in parallel before cutover.
Capture context
Exported code, schemas, and logs form the Context Lake.

Three Ways to Start
Choose the starting point that fits where you are.
The first application, at our cost
For estates of 10+ applications where the decision to move is already made. The first application runs through the full migration pipeline at our cost.
Calculate your OutSystems exit ROI
Enter the number of applications and the average Application Objects per application. See the estimated cost of rewrite, potential savings and your projected OutSystems licence cost.
A fixed-price portfolio scan
SNAP™ reads the estate and returns functional specifications, an API inventory, data-model documentation, and a risk register in the first sprint.
Proof, not promises.
CASE STUDY
An estate nobody could count, on a platform nobody could leave
A global workforce-solutions enterprise built applications independently across regions on OutSystems. They lacked a way to extract the logic, leaving them without leverage at renewal. The blueprint is validated end-to-end, and the factory is running.
