Legacy code, modern future.

We use AI to re-factor, re-write, and re-launch your legacy software into a modern, maintainable, and secure codebase. No drawn-out discovery. No vague quotes.

Why Re-novio

Legacy software costs more than you think. Developers who understand it are scarcer every year. Updates are risky, deployments slow, security holes a constant threat. Renovio re-writes that story.

AI now reads your code

Modern language models can comprehend systems written 20 years ago — PHP 4, Classic ASP, VB6, old Java EE, Delphi.

Fixed price, clear deliverable

For €490 you get a written report: risk assessment, recommended target architecture, and a full rewrite cost estimate. No "contact us".

EU-based, GDPR-aware

You sign with a Slovenian (EU) entity. Your data stays under EU jurisdiction. We sign Data Processing Agreements as standard, and an NDA on request.

How the evaluation works

A simple, four-step process. From submission to report typically 3–5 business days.

  1. 1 · Submit request

    Fill in the form — tell us what system you have, how old it is, and what worries you most.

  2. 2 · Pay €490

    You receive an invoice and instructions to upload code, docs, and access credentials to a secure folder. We sign an NDA on request.

  3. 3 · We run the AI analysis

    Tools like Claude Code, OpenRewrite, and Semgrep read the entire codebase. We identify business logic, risks, and technical debt.

  4. 4 · Receive the report

    A PDF report: current-state assessment, recommended target stack, phased rewrite plan, and a fixed-price quote for the full project.

Stacks we modernize

We specialise in the systems where AI delivers the strongest results. If your stack is not on the list, ask anyway — we often advise on niche technologies as well.

Most common rewrites
PHP 5 / 7

Legacy LAMP systems, jQuery + PHP + MySQL stacks, custom CMSs, old WordPress, Joomla and Drupal builds.

About this stack →
Classic ASP / VBScript

IIS applications from the 90s and early 2000s, typically with SQL Server and COM components.

About this stack →
VB6 / VB.NET / WebForms

Desktop and web apps in Visual Basic — from old desktop programs to ASP.NET WebForms.

About this stack →
Legacy Java (Struts, JSP, J2EE)

J2EE 1.4, Struts 1.x, old Spring 2/3, Hibernate 3, JSP. Common in larger organisations.

About this stack →
AngularJS / jQuery / Backbone

Old, unsupported frontend frameworks: AngularJS 1.x, jQuery monoliths, Backbone, KnockoutJS.

About this stack →
Delphi / Object Pascal

Delphi 5–7 desktop applications and older Object Pascal, common in manufacturing and the DACH region.

Common modernization targets

In the report we recommend a stack that will support your business for the next 10–15 years and stay easy to maintain.

TypeScript + Next.js + PostgreSQL

Default choice for web and internal applications.

PHP 8 + Symfony / Laravel

Ideal if you want to stay in PHP and keep your existing team. Symfony for structured business apps, Laravel for faster delivery.

.NET 9 + Blazor / Minimal API

Best path out of legacy .NET and VB ecosystems.

Java 21 + Spring Boot 3

The right pick for enterprise Java systems.

Python + FastAPI or Go

For API-first architectures and performance-sensitive workloads.

Transparent, fixed-price, no surprises

Three tiers. All prices fixed. No hourly rates, no padding.

Frequently asked questions

If your question is not here, write us — we usually respond the same day.

Can AI rewrite my Delphi (or PHP 5, VB6, Classic ASP …) application? +
Yes — for most older, text-based languages AI is now a highly reliable tool. The key is process: AI first understands the entire codebase, identifies business logic, and then rewrites that logic into the chosen modern stack. Renovio never uses AI unattended — our engineers lead the process and verify every change.
How much does the full rewrite cost? +
The range is wide because it depends on size, complexity, and target stack. As a benchmark: rewriting a medium PHP 5 app (50,000–100,000 LOC) to PHP 8 + Symfony or Laravel typically costs €8,000–€25,000. You get a precise figure for your case in the report (€490).
What exactly do I get for €490? +
A 15–25 page PDF report with: current-state assessment, risk register, identified business logic, recommended target stack, phased rewrite plan, full project cost estimate, security assessment, and 5-year maintenance cost projection. Timeline: 3–5 business days from receipt of code.
What about the security of my code? +
If you want one, we sign an NDA before receiving any code — our template or yours. The NDA is optional and signed only on request. Code is uploaded to a secure folder accessible only to us. After analysis your data is deleted on agreed terms. All our servers are in the EU. We comply with GDPR.
Can I do the rewrite myself once I have the report? +
Of course. The report is yours. It contains enough detail for your team or another vendor to execute. If you continue with Renovio, the €490 is deducted 1:1 from the rewrite project price.
