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 is a visual workspace designed for collaborating with coding agents (like Codex, Claude Code, and OpenCode). It solves the problem of managing complex AI-driven development workflows by providing a single place to handle sessions, tasks, documentation, and code, moving beyond simple chat interfaces to a visually editable environment.

How it works

The platform integrates several tools into one interface:

  • Visual Editors: It provides WYSIWYG editors for Markdown, Mermaid diagrams, Excalidraw, and code (via Monaco), allowing both the user and the AI agent to edit the same files.
  • Session Management: It uses git worktrees to isolate parallel agent sessions, which can be tracked via a Kanban board.
  • Task Tracking: It includes built-in trackers for bugs and features that agents can read and update autonomously.
  • MCP Integration: It acts as an MCP client, rendering tool results as visual widgets instead of raw JSON.
  • Mobile Companion: An iOS app allows users to review diffs and respond to agents via text or voice on the go.

Who it’s for

Developers who use AI coding agents and want a more structured, visual way to manage their projects, review AI-proposed changes, and track tasks across multiple parallel sessions.

Highlights

  • Red/Green Diff Review: Step-through approval of agent edits within rendered documents.
  • Parallel Agent Sessions: Ability to run multiple agents simultaneously in isolated git worktrees.
  • Heterogeneous Agents: Support for various providers including Codex, Claude Code, and Gemini.
  • Extension SDK: A pluggable system for adding custom editors for any file type.
  • Plain-File Storage: All content is stored as plain files in the user's git repository, avoiding proprietary lock-in.
