Crystal (now renamed Nimbalyst) is an open-source Electron desktop app for running multiple Claude Code and Codex AI coding sessions in parallel, isolated via git worktrees. It adds visual editors (markdown, CSV, diagrams, mockups), session management with kanban boards, task tracking, and an extension system around AI-assisted development workflows.

Use cases

  • run multiple claude code sessions in parallel
  • manage ai coding agents with git worktrees
  • compare different ai approaches on the same task
  • review and approve ai code edits visually
  • organize ai agent sessions on a kanban board
  • edit markdown and diagrams alongside ai agents
  • track tasks that ai agents update automatically

When to choose

  • you juggle several Claude Code or Codex sessions at once and need isolation via git worktrees
  • you want a visual workspace with editors, diffs, and task tracking around AI agents
  • you prefer open-source, local-first files over terminal-only agent workflows

When to avoid

  • you only need a single AI coding session in a terminal
  • you want a lightweight CLI tool rather than a full desktop app
  • you need active updates - Crystal is deprecated in favor of Nimbalyst
