Super jank and slow ticketing system. It's flexible in that you can create arbitrary custom fields. This is nice at first, but as a result jira simply doesn't implement many basic features and expects you to add it yourself for each project. Additionally, their API is awful so there's very few tools that can work with it.

jira-cli

The best CLI tool I've found so far. There are a number of others, but they mostly seem very old or poorly written. Unfortunately this one is a very heavy custom TUI which doesn't quite work nicely with other unix tools.

You're meant to set an evironment variable to your API KEY. Rather than set that globally I use zsh-autoenv.
