Nimbalyst
Open-source visual workspace and agent-written wiki for Claude Code, Codex and OpenCode.
Nimbalyst (the successor to the Crystal parallel-worktree app) is an MIT-licensed desktop workspace for macOS, Windows and Linux, with iOS/Android companions, for running multiple coding agents in parallel and editing their work visually across markdown, mockups, diagrams, docs and tasks. It works with existing Claude Code or Codex subscriptions or API keys. A separate Nimbalyst Wiki plugin lets MCP-compatible agents maintain a shared, human-editable wiki of decisions and open questions, with a paid Wiki Teams plan (free in beta).
