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 rules move across through a model built from your real code. Nothing is re-typed by hand, and no AI is asked to guess what your rules do, so they cannot quietly come out meaning something different. We then check the result two ways. Side-by-side testing runs the new system and the old one on the same inputs and compares what comes out. The business rules held in the model give a second, separate check that does not rely on the tests alone.
Model-driven means we read every line of your application and build a model of what it does, then generate the modern version from that model, 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 read every line of your legacy source and build a complete model of its screens, data, and business rules. Nothing is guessed or left behind.
The new application is generated from the model, not translated line for line from the old code. That is what makes the output clean and well structured instead of a thirty-year-old system rewritten in a new language.
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 every system you have: 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 read them into the same kind of model and generate from it the same way.
The model carries your business rules across. They are read straight out of your source code and mapped onto the new system, so nothing is re-typed by hand and nothing is guessed. That is what makes the result something you can check, rather than something that merely looks right.
AI speeds up the work around it: the custom pieces no automated conversion can handle, 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 reads PowerBuilder, VB6, COBOL, Nexaweb and other legacy applications into a complete model of what they do, then generates clean, standard TypeScript/React, 90%+ automated, with the original business rules 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 read every line of the existing system and build a model of its screens, data, and business rules, then generate the modern application from that model rather than translating it line for line. Because what the system does today is captured by a tool rather than from memory, nothing is lost in translation, and the same analysis can 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.
Send us a representative slice of your legacy application. We will modernize it and show you the clean, standard code you would own, before you commit to the full modernization.
