Yellow Lab Tools is a web performance and front-end code quality auditing tool that loads a webpage, collects metrics via Phantomas/Puppeteer, and scores them with detailed issue reports. It is available as an online tool, CLI, Node.js package, public API, and self-hosted Docker/server instance.
Use cases
- audit a webpage for performance issues
- run a page speed test from the command line
- check front-end code quality of my site
- set performance budgets in CI
- self-host a private page speed audit tool
- test localhost pages for web performance
- integrate webperf audits via API
When to choose
- you want an easy-to-read web performance scorecard with in-depth issue details
- you need CLI or API-driven page audits for automation and CI
- you want a self-hosted alternative to online page speed tools
When to avoid
- you need continuous real-user monitoring (RUM) in production
- you need Lighthouse-style Core Web Vitals audits specifically
- you need load or stress testing rather than single-page audits
