How do you deal with weird machine-readable values which you'd like to make some sense of yourself, like a Unix timestamp or a base64-encoded value? Some Bash nerds do "echo ABASE64ENCODEDVALUE== | base64 --decode" to read the encoded stuff, others hit F12 on whatever web page they happen to be at the moment and type something like "new Date(1582889280 * 1000)" (don't forget to x1000 if it's seconds!) in console to see dates (Bash nerds have their "date -d @1582889280" for that), the rest google "base64 decode online" and use some random web tool.

So, this is another random web tool for those tasks and few others. At the moment it helps with URLs (parses & transcodes query values), JSONs (formats & converts them to YAML), Base64 transcoding (including files!), has few crypto functions and, of course, a timestamp converter. There are plans to add a CSV<->JSON converter, a JSON transformer/mapper, a JWT parser/validator, probably a HMAC tool and more.

And the main feature, so rarely found in developer tools, is it's UI. Unlike all the similar tools out in the web, which look like they have been designed by professional programmers, this one is made by a professional programmer who used to date a professional UX designer, so it has both smooth operations & neat looks. There are hotkeys (not many at the moment, but I'm aiming at having full keyboard control over the thing eventually), a sharing feature and data reuse across tools.

We, backend developers, deserve to have nice things too. Give it a shot, I hope one day it finds it's place among your favourite tools.

/!\ Please mind it works only in desktop browsers now. I see not much use for this thing on mobile, but maybe one day a mobile version will follow.
