Codeflash
Freemium · $20/moAI that finds faster versions of your code and verifies them
What is Codeflash?
Codeflash is an AI performance optimizer that rewrites slow functions and proves the new version behaves the same and runs faster. It supports Python, JavaScript, TypeScript and Java. It runs locally, in CI and as a GitHub app.
Codeflash generates candidate optimizations, tests them for correctness and benchmarks real speed gains before opening a pull request. Continuous optimization checks new code on every PR. There are plugins for VS Code and Claude Code, and public open-source repos are free.
