Refactor as you go, ship faster
ACE proposes better ways to structure your code. On the fly. Write clean, maintainable code without breaking your flow. This is the most cost effective time to refactor as the logic is fresh in your mind. It’s also the right time – no more drowning in technical debt.
Automatic quality gates
Quality check and fix AI code
Get real-time code health monitoring for your AI coding assistants. When a code smell appears, our AI-powered add-on safely refactors issues without major rewrites. Only healthy code is pushed to production.

Industry's leading Code Health KPI
Metrics you can trust
Code quality is often subjective, but ACE relies on the proven Code Health Metric to offer clear, research-based recommendations. This means cleaner code, shorter development cycles and fewer bugs.


Fact-based metrics, real-time improvements
Fact-checked refactorings
ACE’s AI-refactorings are fact-checked: LLMs are just one part of a delivery chain that validates all suggestions for accuracy to ensure that they really lead to a measurable reduction in technical debt. Your code stays functional — just better.
Save time on complex code
The future of AI-powered coding is here
Software maintenance accounts for over 90% of a product's lifecycle costs, with developers spending 70% of their time understanding existing code. That's why we've designed a solution that simplifies your work, helping you focus on what truly matters.
Let ACE do the heavy lifting
Refactoring shouldn’t be a burden. ACE does the heavy lifting of improving your existing code, freeing you up for the creative side of development. With minimal, targeted refactorings, ACE simplifies your tasks without massive rewrites, so you can confirm, review, and apply changes quickly.
Quantifiable gains, measurable ROI
ACE delivers more than cleaner code – it drives demonstrable ROI. With ACE, you can show your team and stakeholders the true value of addressing technical debt: shorter lead times, fewer defects, and faster delivery without sacrificing quality. The result is happier teams, satisfied managers, and software that evolves with ease. And: it’s automated.
