Hi, I'm Karl. Greg and I spent the last year building Nimbalyst, an open-source local desktop workspace for working with coding agents.

We want to give agents and humans one place to work together with maximum bandwidth and context, instead of Obsidian for plans, Excalidraw for diagrams, Codex app or Conductor for session management, and Linear for tasks. So we integrated:

- Visual editors for markdown, diagrams, mockups, data models, CSV, code, and your own custom extensions

- Red/green diff review with per-block accept/reject when an agent makes changes

- Session manager with parallel sessions, kanban, search, resume, and links from sessions to the files they touched

- Task tracking where agents and humans create, update, and execute tasks linked to files and sessions

- Developer features like a terminal, worktrees, visual git, and agent-driven commits and branches

Nimbalyst supports Codex, Claude Code, OpenCode (alpha), and Copilot (alpha) through a pluggable provider system.

The desktop and iOS apps are MIT; the collab server is AGPL.

I'd welcome your feedback and contributions.

Iterating on plans with red/green on markdown makes my life much easier
