A new tool by Zach Leatherman that can run locally or on Netlify for running continuous performance measurements.
Has a visual timeline to help create, view, and run animations without having to go back and forth between browser and editor.
Works fast. Just enter a URL and all the images will be displayed in a gallery from where you can download all, or choose the ones you want (for personal use only, of course).
Claims to be 2x faster than React and comes in at less than 2KB.
Currently in private alpha. This tool runs a modern browser headlessly that then draws your website for anyone visiting on an old version of Internet Explorer. We’re linking to this more because it’s an interesting idea.
