A new open-source project tool called Paca drops the separate "AI workspace" sidecar and seats agents directly on the Scrum board, where they plan sprints, pull tickets, write BDD specs and update task status alongside humans in real time.
The design choice that sets it apart: agents are assigned to sprints and appear as teammates on the board, not as a chatbot bolted to the side, with the workflow rooted in the Cynefin "probe, sense, respond" model for adaptive work. It is free, self-hosted and fully open-source, pitched against Jira, Trello, ClickUp and Monday at their US$8-to-20-plus per-seat pricing.
Plenty of tools now add agents. Paca's bet is structural: that human-agent teams need their own native process rather than agents grafted onto software built for people alone.
