Show HN: Paca – Lightweight Jira alternative for human-AI collaboration

A new project called Paca has arrived with a big promise: a free, self-hosted task board where humans and AI work side by side instead of treating AI like a glorified helper bot. Think of it as a leaner alternative to Jira, Trello, ClickUp, and Monday, except the pitch is much spicier: your AI can join planning, grab tasks, help write specs, and update the board like a teammate. That alone was enough to wake up the comment section.

And wow, the crowd did not keep it polite and boring. The strongest vibe was basically, “Jira is cooked.” One commenter flat-out declared, “In my mind Jira is gone,” turning the thread into a mini farewell party for bloated project tools. But right next to that victory lap came a very different mood: several people confessed they’d already built their own weird little custom versions of this exact idea. One person thanked the creator for open-sourcing it, then admitted their own version had become too personalized to ever share. Another said the same thing, with an extra dose of skepticism: these systems get tailored so tightly to one person’s habits that maybe nobody else will ever adopt them.

That’s where the real drama lives. People love the concept, but they also suspect every team secretly wants its own handmade monster. There was cautious curiosity too: one user likes the project-level chat but said they’d only try Paca on a brand-new project, not something already in motion. Translation: exciting idea, terrifying migration. Even the quick “how does it compare to beads?” comment added to the mood—because in true internet fashion, no launch is complete without someone immediately demanding a cage match with a rival. So yes, Paca showed up selling human-AI teamwork, but the comments turned it into something juicier: a referendum on whether big project software is over, or whether we’re all just one prompt away from building our own personal Franken-tool.
