Nimbalyst: Visual Editor for Claude Code & Codex (Open Source)

This open-source visual workspace wraps coding agents like Claude Code and Codex in a desktop environment instead of a terminal. You manage agents, sessions, tasks, and files while editing markdown, CSVs, mockups, code, Mermaid diagrams, Excalidraw drawings, and Prisma-ready data models visually. Every agent edit surfaces as an inline diff you approve or reject, and a kanban board tracks sessions across phases with optional one-click git worktree isolation for running many sessions in parallel.
