A local whiteboard where Codex, Claude Code, and other agents can create cards, plans, and live pages for people to review and edit.

Landing page captured for the 2026-10-27 issue.

For: People coordinating work with Codex, Claude Code, or MCP agents
Worth noticing: Each board is a readable folder with a change history and an inbox for writes from other programs.

Field notes

Commonboard stores each board as a readable folder containing project.json, board documents, history, an inbox for writes from other programs, and assets. Codex, Claude Code, or another MCP client can read and write the board even when the app is closed; users can comment on specific cards and hand changes back to an agent. The homepage lists a macOS Apple silicon download and labels the Windows x64 build experimental.
