What Builders Are Saying

Charlie MarshFounder & CEO of Astral

“CodSpeed has become a key part of the development loop for the Astral toolchain (Ruff, uv, and ty). While continuous benchmarks are typically viewed as challenging and unreliable, with CodSpeed, we get stable, end-to-end and instrumented benchmarks that allow us to avoid regressions and maintain a high-performance culture.”

Samuel ColvinFounder & CEO of Pydantic

“CodSpeed has transformed our development workflow. We can now ship with confidence, knowing performance issues are caught long before they reach our users.”

Yagiz NizipliNode.js Performance Expert

“Seeing clear, consistent results on every PR motivates the whole team to improve performance and avoid regressions before they land. CodSpeed is making performance everyone's responsibility.”

Continuous performance testing for fast-moving teams

Get trustworthy metrics

Stop chasing ghosts in your CI. CodSpeed automatically isolates relevant performance data to bring benchmarking variance below 1%, giving you rock-solid results without the need for manual re-runs or second-guessing.Try It Yourself

Pinpoint root causes

Stop digging through logs. CodSpeed's differential flamegraphs automatically surface exactly which lines of code got slower, mapping out the "why" so you can jump straight to the fix.

Eliminate noise

Our instruments do the heavy lifting by collecting high-precision tracing data and filtering out system jitter, delivering only the clean, actionable performance monitoring insights you need.
