Codeflash

Codeflash is an autonomous performance engineering platform combining an AI agent and senior human engineers to continuously optimize software for cost, speed, memory, and throughput. It autonomously analyzes entire codebases to find inefficiencies, proposes and benchmarks optimizations, and delivers review-ready pull requests, with a human expert auditing each change for correctness and performance. Designed for high-performance ML and data engineering stacks, Codeflash reduces infrastructure costs, prevents regression, and integrates with tools like GitHub and Claude Code.
