Nimbalyst

Nimbalyst is a visual workspace for working with coding agents such as Claude Code and Codex. Instead of living only in a terminal, sessions, tasks, documents, diagrams, mockups, commits and code sit together in one app, and the agent sees the full project context. Every AI change is shown as a diff that the user can approve, reject, edit or iterate on. The app includes agent powered editors for Markdown, CSV and spreadsheets, Excalidraw diagrams, Mermaid, mind maps, data models, wireframe mockups and code. A mockup can be turned into frontend code, and CSV data can be filtered or reshaped by asking the agent. A session manager keeps searchable history, an integrated tracker handles tasks, and a built in terminal, git tools and worktrees support development. Claude Code, Codex, OpenCode and Copilot agents are supported, along with MCP servers, an extension system for building custom visual workspaces and a mobile app for remote session and file management. It works with a user's existing Claude Code or Codex subscription or API key. It is aimed at developers and product managers who run agents in parallel and want to review their work visually. The Individual plan is free and open source, with no account or credit card required. A Teams plan adds real time collaboration on documents, mockups, diagrams and trackers, at $20 per user per month or $200 per user per year, and is free during its beta. Downloads are available for Mac, Windows and Linux.
