FAQs

What programming languages does Codeflash support for optimization?

Codeflash currently supports performance optimization for Python, JavaScript, TypeScript, and Java. It aims to help developers in these languages ship optimal code by identifying and implementing performance improvements.

How does Codeflash ensure that optimized code remains correct?

Codeflash verifies correctness by running existing tests and generating comprehensive regression tests using LLMs and formal verification. This process ensures that the behavior of your code remains unchanged after optimizations are applied.

Does Codeflash introduce any runtime overhead to my production code?

No, Codeflash optimizes code during the development phase. It has zero runtime overhead in production, meaning it will not slow down your project or impact your users once the optimized code is deployed.

What types of optimizations can Codeflash find?

Codeflash identifies various types of optimizations, including better algorithms, removal of wasteful compute, smarter logic, more efficient library usage, and improved concurrency. It aims to make the same improvements an expert engineer would.

Can Codeflash be integrated into a continuous integration workflow?

Yes, Codeflash is designed for continuous optimization. It can be installed as a GitHub Action to automatically optimize new code in pull requests, ensuring that performance regressions are caught and addressed before merging.
