caniuse-cmd
Just what you've always wanted, it's a caniuse command line tool!
All the power of caniuse.com with none of the nice UI or interactivity!
How do?
Install with npm install -g caniuse-cmd.
Then type things like this:
$ caniuse websockets
Web Sockets โ 85.22% โ 1.35% [W3C Candidate Recommendation]

ยนPartial support refers to the websockets implementation using an older version of the protocol and/or the
implementation being disabled by default (due to security issues with the older protocol).
ยฒPartial support refers to lacking support for binary data.
(The output has truly marvellous colours that this markdown is too narrow to contain.)

Woah, that's a lot of options! Can haz config file?
Yes! You can specify your own defaults by creating a file called .caniuse.json
and putting it in your home directory.
For example, if you're primarily interested in mobile browsers two versions back:
{
"era": "e-2",
"mobile": true,
"desktop": false
}
