Nimbalyst is an open-source visual workspace for building with Claude Code, Codex, Opencode (Alpha), and Copilot (Alpha). It integrates parallel session management, kanban boards, WYSIWYG visual editors (markdown, mockups, diagrams, data models), diff review and approval, task tracking, file management, a robust extension system, and a mobile app for remote session management. Integrate your agents, sessions, files, and tasks.

You get the best results with Claude Code when you iterate with it to build full context. Nimbalyst is the local editor and session manager where you iterate with Claude Code on WYSIWYG markdown docs, mockups, diagrams, and code. This is the launch of Nimbalyst's Beta.
