Product summary

Lighthouse is an open-source, automated tool for improving the performance, quality, and correctness of your web apps.

When auditing a page, Lighthouse runs a barrage of tests against the page, and then generates a report on how well the page did. From here you can use the failing tests as indicators on what you can do to improve your app.

Sorprendentemente buena. Genera un informe bastante detallado de una auditoria web, a todos los niveles (SEO, accesibilidad, usabilidad, minificación de archivos, imágenes, etc). Funciona realmente bien.

The overview forgets to mention, you don't need this extension anymore - the feature it built into DevTools in the current version of Chrome. Installing this gives you nothing new. Just use the "Audits" tab in DevTools.

Simply one of the best performance tools you can use. It only continues to improve.

good potential. Currently limited to 1 use case only. More detail should be given for the 3G network simulation as that means many different speeds depending on country.

I think this tool has great potential, but unfortunately, at the moment it is only possible to run an audit emulating on mobile Nexus 5X and using a 3G network connection, which doesn't make much sense to me. At its current state, I'll stick to the DevTools version, where it's possible to choose the emulation options.

It's a good tool, but as it stands it can only generate one report, then the extension needs to be deactivated and reactivated because all buttons in its GUI stops responding after the first usage.
