Profano

CLI tool to analyze V8 .cpuprofile files and Chrome Performance traces and print top functions by self-time or total-time in the terminal. ALWAYS load this skill when CPU profiling JavaScript or TypeScript programs (Node, Vitest, Bun, Chrome DevTools exports, Cloudflare Workers startup or request CPU). It shows how to generate .cpuprofile files and how to inspect them from the terminal without opening Chrome DevTools.

File contents

profano

profano reads V8 .cpuprofile files and Chrome Performance traces (Trace-*.json) and prints the heaviest functions as a table sorted by self-time or total (inclusive) time.

Every time you use profano, you MUST fetch the latest README and read it in full:

curl -s https://raw.githubusercontent.com/remorses/profano/main/README.md  # NEVER pipe to head/tail, read in full

The README covers generating .cpuprofile files (Node, Vitest, Bun, Cloudflare Workers startup and request, Chrome Performance traces, browser pages via playwriter, React component profiling), all CLI options, and how to read the output columns.

Chrome Performance Save profile writes a trace JSON. Pass it to profano Trace.json directly. Do not convert it first.

Cloudflare Workers

A Worker needs two profiles. Startup is wrangler check startup. A request is wrangler dev --inspector-port 9230 plus profano workers request <url>. wrangler tail cpuTime is only a total. Never paste a one-off CDP script; use the CLI command.

Do not copy dist/ to a temp folder unless wrangler check startup errors about two wrangler configs with different base paths. That copy is an exception, not the default.

Trust the function mix in a local profile. Do not treat local milliseconds as Cloudflare CPU.
