Always Ship Optimal Code
Codeflash finds the fastest version of your Python code through AI-powered optimizations, verifies correctness, and automatically delivers performance gains.
Writing Fast Code is Hard
Slow code piles up when it’s hard to recognize opportunities for optimization - and even harder to fix them one by one
The regressions accumulate invisibly in your project until its too late
Detect and Prioritize bottlenecks

Code Change
Slow Code Wastes Time and Money
Revenue
Users notice every slowness and bail out, unlikely to return again
Wait Time
You waste hours waiting for that one job to finish, breaking your flow
Cloud Bills
2x slow code means 2x compute spend, wasting your project’s budget
Codeflash automatically optimizes every line of code you and your coding agents write.
You Build, We Boost

What developers say
Codeflash enables our team to ship blazing-fast computer vision models without sacrificing development speed. We've achieved 25% faster object detection and improved throughput from 80 to 100 FPS-letting our customers run more video streams on fewer GPUs while our engineers focus on building new features which are made performant by Codeflash.
Founder & CTO @ Roboflow
We've used Codeflash in the Pydantic codebase (300M+ downloads / month) to help optimize logic including repeated attribute access patterns and recursive algorithms. We're particularly impressed by the thorough testing and explanations provided by Codeflash which give us confidence in merging the recommended changes.
Software Engineer @ Pydantic
With Codeflash I can now focus only on writing the code and don't have to worry about optimizations. I feel like I have an extra expert engineer optimizing performance for me all the time.
Founder @ GDSFactory
Keeping a large open-source project performant can be quite hard to do. With Codeflash we can be more confident that every new PR is optimized.
Founder & CTO @ Langflow
I've been working on Albumentations, an image augmentation library, for years now. The library is already well optimized. But the Codeflash team submitted over 10 pull requests in just one week, each making our functions significantly faster. The speedups range from 2× to 55× in some cases. I'm now adding Codeflash to our GitHub actions workflow so every PR will automatically get checked for potential performance improvements. It will help make the library even faster and teach everyone who contributes to Albumentations how to write more performant code.
