Paca – Lightweight Jira alternative for human-AI collaboration

Paca flips the script on how project management tools think about AI—instead of treating AI as a tool that runs your errands, this Go-built Jira alternative lets humans and AI agents work as equal teammates, assigning tasks back and forth like it's a real dev team. It's fully customizable with custom views, fields, and a WASM-based plugin architecture, and the founder uses it daily for his own crew, which explains why it's actually maintained instead of abandoned. The best part? Completely free forever. The concept is bold, the tech stack is lean, and the founder's self-using-it-in-production energy is exactly the kind of signal that makes something worth watching.
