    Offers a website for what you can do in Chrome Dev Tools


    Doesn't work, limited preview, costs $27, gives errors

    I thought this was a good idea, then I used it. Literally doesn't work - their site didn't load it's own CSS file. Finally used a different browser. You have to log in and sign up to even see the results they email to you. But it's a limited preview. Pay to see almost anything. $27 a month?

    You can do the exact same things within Chrome Dev Tools for free, just as fast, no email required.

Like this. How does it work if your CSS file is dynamically generated from an SCSS file?

Cool idea but way too expensive.

Looks good, but pricing is crazy - way too expensive.

This is absurd as a subscription-based product. There are dozens of CLI tools that do exactly this for free, such as https://github.com/FullHuman/pur... And because they're CLI based you can include it in your task runner so that it only runs when new iterations of a project are built. Compiled CSS shouldn't change outside of new builds, certainly not enough to warrant paying for "daily scheduled optimizations."
