Is Jira Old News? Meet ‘Paca’, the Next-Gen Scrum Tool with AI as Your ‘Colleague’

News Overview

• AI-Native Scrum Teams: A new open-source project management tool has emerged that treats AI agents as equal ‘teammates’ rather than mere chatbots.
• Autonomous Task Management: AI autonomously picks tasks from the backlog and updates progress in real-time on the Scrumban board, even participating in writing BDD specs and system design.
• High Scalability and Customization: Utilizing a WASM (WebAssembly) based plugin system, users can freely modify workflows and UI. Self-hosting ensures complete ownership of data.

Key Points

• AI Has a ‘Seat at the Table’: Unlike traditional tools that offer mere ‘bonus automation features’, Paca’s core philosophy revolves around having AI participate directly in sprint planning and retrospectives.
• Introduction of the P-A-C-A Cycle: Comprising four phases—Plan, Act, Check, Adapt—this cycle fosters collaborative efforts between humans and AI based on scientific methods.
• Evolution in Latest v0.4.0: The latest version enhances collaboration reliability with in-app AI chat for creating epics and tasks, diff displays for field changes, and one-click restore features.

Shark’s Eye (Curator’s Perspective)

Finally, AI has evolved from being just a ‘tool’ to becoming a ‘colleague’!
Previous project management tools were limited to a ‘one-on-one conversation’ where humans directed AI. But not with Paca! The image of AI standing alongside on the Scrumban board, picking up tasks with a confident, “I’ve got this!” is the standard style for 2026.

What’s truly exciting is the plugin system based on WASM (WebAssembly). Developers can write backend extensions in languages like Go or Rust, and thanks to sandboxing, security is top-notch. With MCP Server compatibility, it seamlessly connects with external tools like Claude Code, making it the ultimate structure that addresses developers’ needs! Paca cuts through the ‘bloat’ associated with existing tools like Jira and ClickUp, adopting a lightweight, AI-first approach that’s just electrifying!

What’s Next?

The role of project management is shifting from “who does what” to “how do we divvy up tasks with AI agents.” As AI-native and open-source platforms like Paca gain traction, we’re on the verge of a time when companies will cultivate their own ‘ultimate AI colleagues’ through plugins.

The day has come when AI runs the sprint! I better swim fast and code hard to avoid losing my tasks! Shark out! 🦈🔥

Terminology

• BDD (Behavior Driven Development): A method that defines system behavior in a form close to natural language using Gherkin scenarios, aligning human and AI understanding.

• MCP Server (Model Context Protocol): A server standard for safely and uniformly connecting AI agents to external data sources, enabling external AI to manipulate Paca’s data.

• WASM (WebAssembly): A binary format that runs efficiently in browsers and on servers. It’s used in Paca to execute plugins within a secure sandbox environment.
