Is there a browser compatibility checker for websites? (lemmy.world)

I have made a website in simple HTML and CSS (no JS).

I hope it would be compatible with as many browsers as possible.

Is there a free and open source solution that can test and reveal the oldest version of each browser compatible with my site? I want to be able to say something like: This site is compatible with FF v60, Chromium v50, Safari vxx, etc.

Or make a compatibility table so users can know that this was tested.

There is this tool if you use stylelint for linting: https://github.com/RJWadley/stylelint-no-unsupported-browser-features

Given that your website is very simple, I assume it would be a pretty big rabbit-hole to dig into.

It wouldn't reveal the oldest version of each browser compatible with your website, but it would check your css against a predefined list, and alert you if you use something that is not compatible.

Otherwise, if you are ok with checking manually, check out BrowserStack: https://www.browserstack.com/ It's neither free or open source, but it simplifies testing on many browsers. There is a free plan as well.
