A tool for analyzing the site during its creation (loading speed, number of requests)?

Question

PHP

When developing sites on any frameworks (symfony, laravel, etc.), there are tools for analyzing the current page, in symfony it is a profiler, when at the bottom of the screen there is a bar with information about download speed, number of requests, sessions and cookies, current controller and action.
Are there such ready-made tools when you make a site without a framework, maybe you can connect to the site through composer?

Answer 1

If you need a stripe, then there are separate ones from the framework.
For example: phpdebugbar.com
But you have to figure out how to integrate it correctly.
