WebPerf Snippets started as a collection of snippets to paste into the DevTools console. With version 2.0, they are also built for AI agents to run webperf-snippets.net 🧵 #WebPerf #AI

webperf-snippets.netWebPerf SnippetsTested JavaScript snippets that measure and debug web performance. Your AI agent runs them for you, or you run them yourself in DevTools: the same code every time.

Agent-run snippets solve the old problem with console pastes: nobody reran them after a deploy. An LCP check on every preview build catches the hero image regression before users do.

Totally agree, and you can use the CLI version webperf-snippets.net/CLI FYI, I have it on the roadmap to publish a GitHub Action

webperf-snippets.netWebPerf Snippets CLIRun curated WebPerf Snippets headlessly via Playwright. Diagnose Core Web Vitals beyond what Lighthouse exposes and gate CI on real performance budgets.

The Projekt

A GitHub Action posting LCP and CLS as a PR comment would put the budget in front of the reviewer before merge, which is when a regression is cheapest to fix.
