I am forced to use jira soon as I was using BB issues and that is expiring soon.

So I'll build something simple for us, that integrates with our systems and how we like to do things.

It won't cost us much since our meagre requirements are nothing comparted to a full fledged Jira replacement.

Without LLMs it would have taken maybe a couple of days effort and perhaps an hour a month to fix any bugs we miss or add an extra overlooked feature.

With LLMs ... we shall see.

We won't set out to solve all of the world's issue tracking problems, so that will save a lot of time.

KISS is the goal.

If your choices are "use Jira" vs. "build task management software with an LLM" then you are already in a losing proposition. Go spend some time with Redmine before building your own. Redmine is free, far better than Jira, and already includes the features you don't yet realize you need.
