As a non infra guy I'll say this. I'm curious about Linear. At my own company I vibecoded my own project management app against the JIRA API because I can't stand our version of JIRA. It's too many clicks, too many things to remember and it's unintuitive.
If you have the power to do so, get rid of JIRA immediately. There are like 10 competitors that are all dramatically better.
I would personally recommend https://www.shortcut.com which is very well designed, and also made some really sensible improvements over the time that we used it.
Baffling piece of software. It's a task manager and every time I use it I flail around for ages trying to figure out how to mark a task completed. No idea why people like it.
Because the customers are hordes of PMs and other types who can use as tool to be taskmaster over hordes of developers.
It's Amazon warehouse worker tracking software for developers and thus we hate it.
Been incredibly happy with the speed, featureset, and pace of new (good) features in Linear. Our team has adopted it quite happily and it gets a ton of good use. Can fully recommend.
As everyone knows JIRA sucks but some perfect implementation of it exists in the ether at some company you will never work at :)
Theses days AI in doc, spec and production lifecycle means we need AI first ticket tooling - haven’t used Linear but I suspect that works far better with AI then JIRA
