## Definition

Paca is an open-source, self-hosted project management platform where AI agents and humans operate as equal teammates in Scrum — not as chatbots bolted alongside existing tools. Built in Go and licensed Apache 2.0, it gives agents a seat on the same Scrumban board, sprint, and backlog as human engineers.

The project launched publicly on [GitHub](https://github.com/Paca-AI/paca) on March 20, 2026, reached v0.4.2 by June 13, and surfaced on Hacker News the same day with 139 points and 54 comments. It positions itself against Jira ($8–$20+/seat/month) with a free-forever model, built-in MCP server, BDD co-authoring, and a WASM plugin sandbox.

## Analogy

Think of it as a shared cockpit for your engineering team — where the AI co-pilot files its own flight plan.

## Why it's emerging now

Jira's seat-based pricing ($8–$20+/user/month) makes no sense when half your 'team' is AI agents that don't need accounts. Paca launched in March 2026 as a free, self-hosted Scrum board where agents and humans share the same sprint natively — and on June 13, its HN debut validated the pain point publicly.
