Description
I built Paca out of pure passion—a free and lightweight Jira alternative written in Go where humans and AI agents work together as equal teammates to plan sprints and assign tasks to each other. It is fully customizable with custom views, fields, and a WASM-based plugin architecture. My team uses it daily for our own development, so it will be continuously maintained and completely free forever

Could you build this?
Partial While a standard task board UI and CRUD backend are easily vibe-coded, implementing a reliable WASM-based plugin runtime alongside a multi-agent orchestration architecture requires deliberate systems engineering.
What it would actually take: A production version would use Go with a web framework like Fiber or Gin, SQLite/PostgreSQL for storage, and a WASM runtime like Wasmtime or Wazero for sandboxed user plugins. The primary complexity lies in designing safe memory-isolated ABI boundaries for WASM plugins and managing real-time agent execution loops with conflict resolution during sprint planning.
Discussion
20 comments analyzed.
Competitors mentioned: Jira, Linear, Multica, Service Now, OpenHands
Concerns raised: Safety of proprietary company info with AI access, Free hosting sustainability and business model, AI going rogue and disrupting sprint; need undo/override capability, OpenHands container-per-agent approach seems heavyweight
Feature requests: Custom workflow triggers in plugin system, Link new cards to past cards (e.g., 'fix bug introduced by that task'), AI agents to analyze stories, tasks, and timeline, Visual surface for planning agentic feature development workflow, Separate agent for 'done' verification (reviewer != author)

Same idea, different domain
Nobody's really built a workflow automation tool for Real estate yet.
