Refactor as you go

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.

Cursor AI - works out of the box    

Download our extension from the marketplace and seamlessly integrate it with Cursor AI. Open Cursor AI’s extension pane, then drag and drop the downloaded CodeScene ACE file. That’s it — real-time code health monitoring is now live.

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-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 your 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.
