Exit OutSystems. Own your code. Stop paying the licensing tax.

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.

IP sovereignty Zero vendor tax ROI in <24 months

Deepest OutSystems tooling in the factory. Proven OML-to-high-code conversion pipeline.

  • Full OML parsing
  • Idiomatic output
  • Behavioral equivalence tests
  • Phased cutover

The OutSystems cost trap

Staying costs millions. A manual rewrite takes years. There's a third option.

The problem with staying

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.

The problem with manual rewrites

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

AI converts your OML deterministically. Architects own the structure.

OML parsing

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.

High-code generation

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.

Equivalence testing

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

We prove code quality before you commit to the full migration.

Start with a fixed-price diagnostic. If the conversion quality doesn't meet your bar, you owe nothing beyond the diagnostic fee.

Proof of Architecture Diagnostic

€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.

Migration Factory

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.

Enablement & Residency

€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

Owned codebase. Zero licensing tax. Abundant talent.

100%
IP ownership — your code, your repo, no proprietary runtimes
Zero
Application Object licensing cost from Day 1 of cutover
3–5×
faster migration vs. a manual rewrite from a tier-1 SI
Year 2
cash-flow positive — migration cost recovered from eliminated license fees

Next step

Ready to end the licensing tax?

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.
