Find the right extension for the job
Each comparison explains what a tool reads, what it measures and where it gives up. We make one of the tools on these lists and say so on every page.

How we compare
Is Design Toolkit on these lists?
Yes, and every page says so at the top. Design Toolkit is ours. We describe its weak spots the same way we describe everyone else's.
How do you choose what to include?
We list tools by the job they do and by what they read: values, states, motion. A tool earns a place by being useful for that job, not by being popular.
How often are the lists updated?
When a tool changes in a way that matters. Every page shows the month it was last reviewed.
Where do I learn how to do the job itself?
The guides explain each task step by step, with and without an extension.
