OhMyPerf is a real-Chromium CWV measurement tool that fits the Open source tools section alongside Perfume.js (field-data monitoring) and Falco (analysis + optimization). Differentiation vs the existing entries: - Perfume.js: lab-style field RUM, JS library — OhMyPerf is a full standalone tool with its own browser runner, CLI, MCP server, and shareable static viewer. Both have a place: Perfume for prod RUM beacons, OhMyPerf for CI / pre-deploy budget gating + agent fix loops. - Falco: WordPress-focused performance analyzer — OhMyPerf is framework-agnostic, runs against any HTTP(S) URL, and reports ROI-ranked patch candidates with first-party/third-party tagging via 'originClass'. For the 'Tools to measure Performance Budget' lane, the closed agent fix loop is the specifically novel piece: 'verify_fix' runs the candidate URL N times, applies a Mann-Whitney U significance test at alpha=0.05, and returns a structured per-metric verdict — solving the flake problem that fixed-threshold Lighthouse-CI budget gates have. Apache-2.0, public repo (https://github.com/hoainho/ohmyperf), v0.1.0 on npm at @ohmyperf scope, v0.2.0 pending publish.

Adds OhMyPerf to the Open source tools section — a real-Chromium Core Web Vitals measurement tool with a closed agent fix loop and statistical regression detection.
Why this list fits
OhMyPerf is purpose-built for the budgeting use case this awesome list covers:
verify_fixruns the candidate URL N times against a baseline and returns a structured per-metric verdict (improvement | neutral | regression) with p-values.trustScorethat decomposes intosampleConfidence(is n big enough?) +effectConfidence(is the signal noisy?), plus arecommendedActionper metric. No more pretending 3-run measurements are precise.Distinct from existing entries
What you get
@ohmyperf/cli—ohmyperf run <url>,ohmyperf diff baseline.json candidate.json@ohmyperf/mcp-server— 16 tools so AI agents can measure, propose fixes, and verify@ohmyperf/eslint-plugin— 7 CWV-linked ESLint rules at editor-save timeStatus
@ohmyperfscope; v0.2.0 pending publishThanks for maintaining this list — performance budgets are still under-tooled in 2026 and a curated list like this is how teams find the right primitives.
