A Vibe Kanban alternative with a shared board

Vibe Kanban's company shut down and its shared board is gone. Mirasim keeps a team board of items next to coding agents running in their own worktrees.

Mirasim's Items board: a task with its checklist, owner and a button to start a session for itMirasim's Items board: a task with its checklist, owner and a button to start a session for it

The short answer

On April 10, 2026, bloop, the company behind Vibe Kanban, shut down. Its remote services, including kanban issues, comments, projects and organisations, were removed after 30 days. Local workspaces still run, and the project lives on as open source maintained by the community.

What went away is the shared board. Mirasim has one: the team's items sit in a list or a board in the same space where coding agents run, and an item can start a session that runs in its own Git worktree.

Setting up the board in Mirasim

  1. Make your computer a collab space

    Items live in collab spaces. Turning your own computer into one is free; a hosted team space works too.

  2. Add items and switch to the board

    Write items at the top of the list, or pick them out of an agent's answer, then switch from List to Board.

  3. Start a session from an item

    Open an item and choose New session. Tick worktree so each item's work stays on its own branch.

Limits to know about in Mirasim

  • Mirasim isn't open source.
  • Gemini CLI, GitHub Copilot, Amp, Cursor and Droid aren't among the agents Mirasim runs.
  • The board is on the desktop; the phone app shows items as a list.
  • Mirasim doesn't import Vibe Kanban tasks.

Questions

Is Vibe Kanban shut down?
The company behind it, bloop, shut down on April 10, 2026, and the remote features were removed. The open source project and local workspaces continue, maintained by the community.
What can replace Vibe Kanban's shared board?
In Mirasim, items in a collab space have a board view shared by everyone in the space, and each item can start an agent session.
Can several agents work on one repository at once?
Yes. Give each session its own worktree, so each agent works on its own branch and you decide what to merge.
