"I use it every day and honestly can't live without it. Saves me tons of time."
@hardfist_1, lead of @rspack_dev at ByteDance, on the CodSpeed Wizard.
So proud and excited to build the performance agent for the fastest projects on the planet!

"If you're gonna ship slop, at least make it fast."
Our top sticker at PyCon and there's a reason: code has never been cheaper, reviewers are under pressure and regressions are piling up.
Stop thinking about performance, we'll make your thing faster.

Claude Code can now improve performance and fix regressions.
The CodSpeed plugin just landed on the official marketplace.

Codspeed is so good for efficient parsers I always set it up now on any rust code

i pair it with spec driven dev, coderabbit reviews on PR, and a lot of unittests, snapshots tests and codspeed tests and yes it's quite good. I was hesitant but running on it everywhere now

/goal for finding silly one-line optimizations that speed up your parser by 20-30%

/goal and CodSpeed are an excellent combination for micro-optimization work. We’ve seen similar optimization wins in SWC.

Things get wild when @hardfist_1 uses Codex.
He just made SWC parser 20% faster and minifier 10% faster 🤯

You can now use CodSpeed to optimize your code directly from your Agents. This ships with skills to optimize performance iteratively and also MCP tools enabling context-efficient profiling analysis by agents.

Had a great time on the @pybites Podcast with @bbelderbos talking about what pushed me to build @CodSpeedHQ. From building an ODM for MongoDB to obsessing over software performance.
We cover the genesis of CodSpeed, Python perf, and why catching regressions early changes everything.

Launch week, update #4
Search filtering across all benchmark pages.
GitHub-style queries like:
`is:regression mode:walltime parser` 👇

Launch Week II, Day 3: @CodSpeedHQ Memory Instrument 🧠
Memory tracking in CI with:
• peak memory
• total allocations/bytes
• allocation timeline
Flip on `mode: memory` and spot leaks regressions early!

Day 2: WallTime granularity improvement! ✨
Jan 20
Launch week, update #2 👋
CodSpeed Walltime now exposes hardware performance counters directly in CI.
You can see why performance changes: CPU cycles, instructions retired (how much actual work the CPU did),
and cache/memory behavior
Available now with macro runners!
