Nimbalyst Advantages
Where Nimbalyst shines
Agent-agnostic workspace
Run both Claude Code and Codex sessions in the same workspace. Compare results, switch between agents per task, and manage everything on one kanban board.
Visual editors for design artifacts
When your agent creates diagrams, mockups, or data models, Nimbalyst renders them in purpose-built visual editors rather than plain text.
Planning and tracking built in
Create plans, track tasks, and connect work items to sessions. Your agent reads the plan and executes tasks in order.
