About Lighthouse
Lighthouse loads a page under controlled conditions and scores it on performance, accessibility, best practices and SEO, listing the specific problems found and their estimated cost. It runs from Chrome's developer tools, a command-line tool, a Node module or CI.
Strengths
- Turns vague performance complaints into a specific, prioritised list
- Runs in CI as well as in the browser, so regressions can be caught
Limitations
- Scores vary between runs and depend heavily on the machine and network
- A good score is not the same as a fast experience for real users
