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.

"I'm surprised with ACE's suggestions, as they are quite similar to what I would have come up with myself, saving me time and cognitive effort."

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.

What code smells are supported?

Complex Conditional Bumpy Road Ahead Complex Method Deep, Nested Complexity Large Method and more soon to be supported. 

What LLMs are you using?

We are using a blend of LLMs from different vendors, given type of code smell and language, we pick the LLMs likely to produce the best results. Currently we are using LLMs from OpenAI, Antrophic and Google.

Is CodeScene ACE free?

Yes, the freemium plan allows for free usage. There is however a credit limitation on how many LoC that can be refactored within a period of time. When limit has been reached credits will be replenished again within a couple of days. Future releases will offer more functionality and possibility to purchase unlimited credits of refactorings.

Do you train AI models based on our code?

No. Your code stays private and is never used to train AI models. We designed CodeScene ACE with strict privacy principles to protect your intellectual property. Learn more about our approach
