yellowlabtools v3.0.0

Analyzes a webpage and detects performance or front-end code quality issues. Free, easy to launch, easy to understand, in-depth details.

How it works

The tool loads the given URL and collects various metrics and statistics with the help of Phantomas. These metrics are then categorized and transformed into scores. It also gives in-depth details so developpers can fix the detected issues.

By the way, it's free because I am a geek, not businessmen. In return, you can add a ★ on GitHub, it will boost my motivation to add more awesome features!!!

Install your own private instance

If your project is not accessible from outside or if you want to test your localhost, you might want to run your own instance of Yellow Lab Tools.

The classical way is to clone the YLT server's GitHub repository and run it on Linux or MacOS. The documentation is here.

The new recommended solution is to run Yellow Lab Tools inside a Docker virtual machine. My friend Ousama Ben Younes maintains this ready-to-use Docker image based on Alpine).
