At some point, I got tired of typing crates dot io slash crates slash blah every time. npm has https://npm.im and https://ghub.io, so why shouldn't we have something cool?
Well, I made https://cra.tw, which does basically the same thing. You type https://cra.tw/serde, you get https://crates.io/crates/serde. It doesn't do much more.
The source is here: ~lyn/cra.tw - sourcehut git.
Then now there are at least 2 ways to easily access Cargo crates, the other option being a "search engine shortcut" (which can be done in both Chrome and Firefox, I'm not sure about other browsers). The latter option allows you to simply type e.g. crate serde (where crate is a user-definable keyword that activates that "search engine") in the URL bar and it will go to the serde crate page.
