Nimbalyst: Visual Workspace for Codex and Claude Code With Kanban and Mermaid Diagrams

Key Takeaways

• Nimbalyst requires an existing Codex or Claude Code subscription — it uses your existing credentials and adds a visual project management interface on top.
• Core visual features: Kanban board for task tracking, Mermaid diagram rendering, and Excalidraw integration for visual system design.
• Autonomy levels map directly to native agent permissions: "Ask questions" (default), "Allow edits" (moderate), "Allow all" (equivalent to Codex yellow mode / Claude Code's --dangerously-skip-permissions).
• Open new folders directly from the interface — no need to pre-create a project before starting; ideal for greenfield experiments.
• Not locked to one agent: switch between Codex and Claude Code within the same workspace, using whichever is better suited to the task at hand.
• Project management features (Kanban, planning, task tracking) cover the gap between raw CLI and fully IDE-integrated workflows.
