From no-code to production code, without the rewrite tax.
yonocode.io ↗Enterprises reach a point where the annual OutSystems bill exceeds the cost of owning the equivalent code. We migrate module by module behind a router, so nothing stops while the exit happens.
Old and new run side by side behind a routing layer. Modules move individually, and each one can be rolled back on its own.
Because modules retire progressively, the commercial benefit starts before the migration finishes rather than at the end of a multi-year project.
React and Node or .NET engineers are abundant. OutSystems specialists are not, and that scarcity is priced into every hire and every contractor.
Extensions and integrations become typed clients with retries and observability, rather than platform artifacts nobody wants to open.
Runs in your AWS or Azure account under your security posture, monitoring, and compliance regime.
The exact mental model we use during migration. If you're scoping internally, copy this table.
Every module scored on business criticality, change frequency, and technical complexity. High-churn modules migrate first because they generate the most ongoing licence value.
A router is placed in front so traffic can be directed per module. This is what makes the phased approach safe.
The entity model becomes a schema you own, with data synchronised until each module cuts over.
Modules rebuilt and released one at a time, each behind a feature flag with a rollback path.
Extensions and external integrations become typed service clients with retries, timeouts, and monitoring.
As the last module moves, the OutSystems environment is archived and the licence is not renewed.
A rough but realistic estimate based on real client benchmarks. Hosting and per-seat fees only — engineering productivity gains are on top.
30–100 screens, custom integrations, role-based access.
Estimates use median list pricing for the selected platform and median DigitalOcean / Vercel hosting for an equivalent code-based app, plus modest dev-ops time. Real numbers depend on usage, integrations, and compliance scope.
We protect our clients' privacy by referring to them by industry, region, and stage. Every metric below is a direct lift from a delivered migration.
Workflow timeouts during peak loads and an upcoming SOC 2 audit that the no-code stack could not satisfy.
"We thought the move would freeze the product for months. The team shipped feature parity in five weeks and we passed SOC 2 right after."
Fixed-price packages. Scope is locked at the kickoff. Anything not on the list is free during the migration window.
Single-product apps under 30 screens with standard integrations.
Apps with custom integrations, real users, and growth pressure.
Regulated industries, multi-tenant SaaS, mission-critical apps.
Need only the backend, only the public site, or just one module? Ask about Partial Migration — same workflow, scoped to what hurts most.
Enterprise migrations run 6 to 18 months depending on module count, and that is deliberate — the phased approach trades speed for the ability to keep operating. Commercial benefit starts as soon as the first modules retire.
No. Some organisations keep a small OutSystems footprint for genuinely low-change internal apps and migrate only the modules where the licence cost or the delivery speed hurts. We will help you draw that line honestly.
Usually yes, and it is worth planning for. Developers who know your domain are more valuable than developers who know React. We pair with internal teams through the migration specifically to transfer the stack knowledge.
Often they port with little change if you choose .NET as the target backend, which is one reason we do not push everyone to Node. The right target stack depends on your team, not our preference.
