Source Stack · OutSystems
OutSystems scales your licensing cost alongside your success — the Application Object model means the more you build, the more you pay. Our AI factory converts your entire OML estate into clean, idiomatic high-code in a fraction of the time and cost of a manual rewrite. Phased delivery. Full IP ownership. Cash-flow positive by Year 2.
Deepest OutSystems tooling in the factory. Proven OML-to-high-code conversion pipeline.
The OutSystems cost trap
As your application estate grows, so does your OutSystems invoice. Application Objects multiply with every feature, every integration, every screen. The more successful your product, the higher the tax. You're locked into a pricing model that penalizes growth.
Traditional rewrites of OutSystems estates take 2–4 years, cost 8–15M euros, and carry enormous human-error risk during translation. Teams burn out. Business logic gets lost. Feature parity is never fully reached. Most projects drift and stall.
Inside the OutSystems factory
Our AI ingests your OutSystems OML files and builds a complete map of every entity, screen, business rule, integration, and data flow. Every artifact is logged and inspectable — nothing goes into the conversion as a black box.
The AI emits idiomatic, maintainable high-code in your chosen target stack — C#/.NET, Java/Spring, React, Node.js, or another modern framework. Senior architects review every structural decision. AI handles the volume; humans handle the judgment.
Before any cutover, the AI synthesizes behavioral tests that compare new system output against the live OutSystems system output. You migrate on a passing diff, not on faith.
Three engagement stages
Start with a fixed-price diagnostic. If the conversion quality doesn't meet your bar, you owe nothing beyond the diagnostic fee.
€25k – €50k
3–4 week turnaround · fee credited to full migration
Provide one medium-complexity OML module. We run it through the AI engine and deliver clean, idiomatic high-code with a full technical audit and performance benchmarks. You see the output quality before committing to anything larger.
Fixed price
Typically 1.5× – 2× your annual OutSystems license cost
SLA-backed AI conversion of your entire OutSystems footprint into owned, maintainable high-code. Delivered in months, not years. Phased releases with parallel running. Cash-flow positive by Year 2.
€20k / mo
6–12 month retainer
Architectural support to onboard your standard engineering team into the new codebase, CI/CD pipelines, and delivery cadence. We stay until your team owns it fully.
What you walk away with
Questions we get
No. We parse your OutSystems source into a complete structural map first — every entity, screen, business rule, and integration — deterministically, not by asking a model to guess what your code does. AI accelerates the generation step from that map; a senior architect reviews every structural decision; behavioral equivalence tests verify the result against your live system before any cutover.
Your source and data are used only to produce your migration deliverables — never to train or fine-tune any AI model. Access is scoped to what a given phase actually needs, and production data access, where required at all, is time-boxed by agreement. Everything delivered is yours outright, with no ongoing dependency on us.
Yes, always. Every architecture decision, every equivalence-test result, and every cutover is reviewed and signed off by a senior architect before it reaches production. AI handles the volume; it doesn't approve its own work.
That's what the feasibility opinion below is for. Send the basics and a senior architect will give you an honest read — including "this probably isn't worth it yet" if that's the honest answer — before any paid engagement.

No sales call required. Send the basics and a senior architect will reply with an honest read before you commit to a paid diagnostic.
A senior architect will reply directly — no automated sequence, no sales pitch.
Next step
Start with the Proof of Architecture Diagnostic. Fixed price, 3–4 weeks, and the fee is credited against the full migration if you proceed. If our conversion quality doesn't meet your bar, you owe nothing more.
Go deeper
The specific questions that come up once leaving stops being hypothetical.
What you actually cannot take with you, itemised — instead of the usual hand-waving.
The official exit route, and the gap between what it produces and code you would choose to maintain.
What changes structurally when the platform stops generating your application for you.
The step most plans gloss over, and why it decides the timeline more often than the code does.
