Show HN: Paca – Lightweight Jira alternative for human-AI collaboration
109 points - today at 9:44 AM
I built Paca out of pure passion—a free and lightweight Jira alternative written in Go where humans and AI agents work together as equal teammates to plan sprints and assign tasks to each other. It is fully customizable with custom views, fields, and a WASM-based plugin architecture. My team uses it daily for our own development, so it will be continuously maintained and completely free forever

We're using GitHub for everything here, but was using Jira as an email first helpdesk.
Was hoping this was that - but apparently not at all.
We almost went with libredesk - but it's a little too simple (no merging tickets?). We're giving FreeScout a go - looks like we might need the oauth2 plugin to work with o365 mail ...

> A lot of software developers are seduced by the old “80/20” rule. It seems to make a lot of sense: 80% of the people use 20% of the features. So you convince yourself that you only need to implement 20% of the features, and you can still sell 80% as many copies.
> Unfortunately, it’s never the same 20%. Everybody uses a different set of features.

However I'm getting a 404

(You need to enable private security advisories: https://docs.github.com/en/code-security/how-tos/report-and-..., really not sure why GitHub made it opt-in only)
As I use claude more and more I've started using git worktrees, one branch per worktree per PR, with possibly multiple agents working in each worktree at the same time on different aspects. And I manually instruct those agents. Like Emdash/Cursor/Zed. Sometimes I review code locally, sometimes agents push and I review in GitHub, no clear system yet. (jj seems promising, but Zed doesn't seem to support jj as well as git, so have delayed looking at it.)
But Paca is hinting in another direction where the agents are more in control of the branches/worktrees to use and are created by the agent? What tooling is used to support such flows? Would people use GitHub with Paca or is GitHub redundant as well.
This is what I did with this project https://github.com/crmkit/crmkit/ and to be honest the approach grows on me and fits well if you are a backend person.

Their skills abuse your context window and billing, you'll want to write your own for the 20% you use
Everyone ends up with a workflow shaped really tightly around how they work, and it's gotten so cheap to just build and evolve your own as the models and harnesses change that picking up someone else's stops making much sense.
Glad to I'm not the only one thinking about moving away from Jira
Where does Jira really sit in a world eaten up by vibecoding?
