Nimbalyst

The product is an extensible visual workspace that unifies agent sessions, tasks, docs, diagrams, mockups, and code in one place so users do not have to edit in one application and work with coding agents in another. It sells to developers, product managers, and feature teams in startups, consulting firms, and enterprises that build software with Claude Code and Codex. It is delivered as a local-first, open-source desktop application with a multiplayer Teams option and works with an existing Claude Code or Codex subscription or API key.
