We’ve been holding this one back for a while… Not because we didn’t want to build it, but because we didn’t want to sacrifice our key objective: measurement consistency and reproducibility. Now it’s ready! Enjoy 🚀
We just released Benchmark-level performance gates! ⚡🚪 Whether you're hunting for instructions and cache accesses or just measuring global latency, you can have it all in a single performance report!

Inlining Information is now available in @codspeedhq flame graphs. You can now track how the compiler inlines your code directly in the UI. codspeed.io/changelog/2025…
We just shipped a pretty huge performance improvement to the @codspeedhq GitHub Action 👇 codspeed.io/changelog/2025…
We've fixed it! All runs on GitHub Actions are now ~2 minutes faster! ⚡ codspeed.io/changelog/2025…

Walltime profiling is now available across Rust, C/C++, Python, and Go! 🚀⚡ Get detailed flamegraphs powered by perf to pinpoint bottlenecks in real-world scenarios! codspeed.io/changelog/2025…
Fantastic talk/quizz by @codspeedhq founders They shared very clear explanations of why pieces of code are fast/slow, and how one can understand why by looking at the final assembly #eurorust25
Time to fix 🔨👷

First @codspeedhq benchmarks in Zig are here! Kudos to @James_Elicx for kickstarting the integration with our instrument hooks!
New feature release today ✨
🚀 Major change in how @codspeedhq analyzes performance tests: Partial Runs are live. Making the performance feedback tighter than ever before. codspeed.io/changelog/2025…
We've just added more minutes of macro runners for open-source repositories! codspeed.io/changelog/2025…
New language support today! (more to come this month, stay tuned 😉)
🚀 Cool news for Go developers! We’re excited to announce that CodSpeed now supports Go 🐹⚡ codspeed.io/changelog/2025…
New blog post on measuring walltime in CI!
We ran over 100 Walltime benchmarks on GitHub-hosted runners and compared them to our Macro Runners, and the variance difference is significant. 2.66% vs. 0.56% and that’s the difference between 45% false positives and 0.04% codspeed.io/blog/benchmark…
New improvements! 🚀
Really excited to get those improvements out for the profiling experience with CodSpeed⚡
We're launching a new product! 🚀 Check it out: p99.chat
Announcing p99.chat, the assistant for software performance optimization 🚀 Describe your performance challenge, share your code, and p99 will analyze, instrument, and visualize the results, cutting the traditional setup overhead down to seconds!
We’re at @pyconit with @adriencaccia We’ll quizz you on Python performance again tomorrow! See you in room lasagna at 11:45!
