Nimbalyst - The open-source visual workspace for Claude Code, Codex, and OpenCode. Run multiple coding agents in parallel, edit their work visually in markdown, mockups, and diagrams, and track tasks. Free, MIT-licensed desktop app for macOS, Windows, Linux, with mobile companion for iOS and Android.

What it solves

Nimbalyst provides a visual interface for developers, product managers, and designers to collaborate with AI coding agents like Claude Code and Codex. It bridges the gap between raw terminal-based agent interactions and visual workflows by providing a centralized workspace for managing sessions, tasks, and file edits.

How it works

The platform uses a visual editor to allow humans and AI agents to work together on various file types including Markdown, Mermaid diagrams, Excalidraw mockups, and code. It features a WYSIWYG interface where users can review AI-suggested changes using red/green diffs. It also includes a session manager to run parallel agent workstreams and a task manager that agents can interact with to add, move, or execute items.

Who it’s for

  • Developers looking for integrated git management, terminal access, and visual diff reviews.
  • Product Managers and Designers who need to collaborate on mockups, diagrams, and task lists with AI.
  • Builders who want to manage multiple AI agent sessions in parallel using a Kanban-style interface.

Highlights

  • Visual Collaboration: Review and approve AI changes via red/green WYSIWYG diffs across code, markdown, and diagrams.
  • Session & Task Management: Manage multiple parallel agent sessions and track plans, bugs, or todos in a Kanban board.
  • Developer Tooling: Includes an embedded terminal, AI-powered git commits, and support for git worktrees.
  • Extensible Architecture: A pluggable system that allows users to build custom editors for any file type.
  • Mobile Access: A companion app to monitor agent progress and respond to agent queries on the go.
