Paca: Lightweight Jira Alternative for Human-AI Collaboration

Paca (GitHub: Paca-AI/paca) is a minimal Jira alternative built for teams that collaborate with AI agents. It features a kanban board, ticket creation, and automatic assignment of tasks to AI or human workers based on skill tags. The tool integrates with LLMs to allow AI agents to update ticket status, generate subtasks, and comment with reasoning. It tracks token usage per ticket for cost transparency. Paca is built as a single binary with SQLite, making it easy to self-host. The project is aimed at small teams and startups that want a simple, AI-friendly workflow without the overhead of complex tools like Jira. The developer says it reduces meeting overhead by letting AI handle status updates.
