PowerBuilder, VB6, COBOL, Nexaweb and more, transformed into modern TypeScript / React. The model carries your business logic across exactly. Our engineers and AI handle everything around it.
Trusted with enterprise modernization
Roughly 74% of legacy modernization projects fail, and they fail on the same thing: nobody can prove the new system does what the old one did. That is the problem we built the model for. We lead with these answers because they are what set us apart.
Your business logic is carried across through a structured model, never re-typed and never inferred, so it cannot be quietly mistranslated. We then verify it twice over. Side-by-side automated testing runs the modernized system against the original and compares the results. The business rules captured in the model give a second, independent check that does not depend on the tests alone.
Model-driven transformation parses your application into a model, then generates the modern equivalent, 90%+ automated. You avoid the cost, risk, and multi-year timeline of re-implementing decades of business rules by hand.
We transform your system into clean, standard TypeScript / React, not a proprietary runtime or a black box. The output is readable, conventional code your team can maintain, extend, and take anywhere.
Low-risk by design: your business logic is carried through the model, not re-implemented by hand.
We ingest your legacy source and build a complete model of its screens, data, and business logic. Nothing is guessed or left behind.
The model is mapped to a modern architecture and the new application is generated automatically, with the original business behavior preserved.
You receive clean, standard TypeScript / React your team owns: responsive, maintainable, and ready to extend on current frameworks.
The same engine that built a 15-year track record, now available behind your own team or your own brand.
Automated analysis of the whole estate: every screen, module, data path and dependency, the business rules embedded in them, and where the risk is concentrated. It recovers accurate documentation from systems whose documentation went stale years ago.
The model is mapped onto a modern architecture and the new application is generated from it, 90%+ automated. Business logic travels through the model rather than being re-implemented, which is what makes the output verifiable against the original.
Most modernization specialists take on COBOL and stop there. The mainframe is only part of the problem. PowerBuilder, Visual Basic 6, Oracle Forms and Reports, RPG on IBM i, Classic ASP, .NET WebForms, Delphi, Nexaweb and Biz/Browser run business-critical systems too, and they are just as hard to staff. We parse them into the same kind of model and generate from it the same way.
The model carries your business logic across. It is parsed from your source and mapped to the new system structurally, so it is never re-typed by hand and never inferred, which is what makes the result verifiable rather than merely plausible.
AI accelerates the work around it: the custom pieces no generator can produce, building the test coverage, and filling gaps where the original code is unclear or incomplete.
Our engineers check the result against the original system and stand behind it. There is a fashionable idea that modernization should run with nobody in the loop, no one authoring the code and no one reviewing it. That is a comfortable promise right up until a core system in a bank, a hospital or a government department behaves differently on Monday morning than it did on Friday. Take any one of the three away and you have the failure mode that sinks modernization projects.
You have a business-critical legacy system that is getting harder and more expensive to maintain. Modernize it into clean, standard code without the risk of starting from scratch.

An explicit invitation to partner, the same model that built our Japan channel.
Partner with us →Vivify Technologies is a legacy-modernization specialist: we transform aging business systems into modern code their owners control. Fifteen-plus years of modernization heritage, engineering led from Japan, delivering directly and through SI partners.
Vivify Technologies modernizes legacy systems. Our model-driven engine parses PowerBuilder, VB6, COBOL, Nexaweb and other legacy applications into a complete model, then generates clean, standard TypeScript/React, 90%+ automated, with the original business logic preserved.
Yes. PowerBuilder-to-web is one of our most common conversions. The same process covers VB6, COBOL, Nexaweb, and legacy web stacks; the approach is source-flexible.
Parse, transform, deliver: we build a model of the existing system’s screens, data, and business logic, then generate the modern application from the model. Because the as-is functionality is captured mechanically, nothing is lost in translation, and the same analysis can even serve as the baseline specification for a rewrite.
Vivify Technologies is a brand of Fluxweave LLC (US), with engineering operations led from Japan and a sister engineering company, Fluxweave. In Japan we deliver through established SI partnerships; the same partner model is expanding internationally.
