A free, lightweight alternative to Jira, specifically designed for human-AI collaboration in sprint planning and task assignment. Emphasizes customizability and continuous maintenance.
Paca targets the project management software market, specifically positioning itself as a lightweight, free alternative to Jira. Its core differentiator is the explicit integration of human-AI collaboration, where AI agents function as 'equal teammates' in planning and task allocation. This addresses an emerging trend in software development where AI assists in workflow optimization. The WASM-based plugin architecture suggests extensibility and adaptability, crucial for enterprise adoption. By offering a free, continuously maintained solution, Paca could disrupt segments of the market currently underserved by expensive, feature-heavy incumbents, particularly for teams experimenting with AI-driven project management or those seeking a more agile, less cumbersome tool.
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

I like that, its cool
I can't believe you guys give this for free. I was considering buying "Linear", now I just saved 10$/month with this. Thank you so much
You can take it a step further and strip out the frontend. Honestly. Nobody needs it and if you need any UI stuff it in the MCP.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.
What are people's workflows these days?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.
I've been trying keeping an eye on open source issue trackers/project managament tools I can self-host -- with good cli/mcp capabilities. So quite happy to see this as I feel there isn't a lot! (currently also using gh issues) will check it out!
Backlog.md the project: tasks live in your repo, atomic and race free
People who like Jira (or rather want; I doubt one ever “needs” this thing), and make decisions on its implementation and payment, and force it on others, are not the people who are shopping for alternatives. So who these alternatives are really for?
Awesome to see this. Like a few others here, I hand-rolled (well, Codex-rolled) something similar that works great for me. I keep going back and forth on open-sourcing it, but my hunch is people won't really adopt these kinds of things anyway.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.
Specifically on the AI side, how does it compare to beads?
I'm using GitHub issues and GitHub Projects with `gh` cli and I find it works well, though what I really like about this is your project level chat. I find myself having to come back to a project level session often. May give this a try, just hesitant to put it on something that's in-flight with already lots of stuff, will have to be a net new project.
