Codeflash
AI code optimizer that rewrites Python functions for performance and verifies correctness in CI
About Codeflash
Codeflash is an AI-powered performance optimizer for Python (with JavaScript and Java support) that automatically rewrites functions to run faster while verifying correctness through existing tests. It runs as a GitHub Action in CI pipelines, opening pull requests with optimized code and benchmark results showing measured speedups. Teams at Roboflow, Pydantic, and Langflow use it to catch performance regressions and improve code introduced by coding agents.
