About Nimbalyst
Nimbalyst is an open-source visual workspace for builders who work with coding agents like Codex and Claude Code. Instead of managing agent chats, files, plans, diagrams, and git changes across separate tools, Nimbalyst brings them into one local-first desktop environment.
The platform is designed for agent-native development: you can run and resume sessions, review AI changes visually, edit markdown or code, diagram systems, track tasks, and connect tools through MCP. It is especially useful for developers, technical founders, and product teams who want more control and visibility when AI agents modify real project files.
Key Features
Agent session management : Run multiple Codex and Claude Code sessions, organize them, search history, resume past work, and branch sessions when a task needs a new direction.
Visual markdown editor : Write plans, specs, notes, and documentation in a WYSIWYG markdown editor while agents can read, edit, and propose changes.
Red/green AI diffs : Review AI edits as visible diffs before accepting, rejecting, or modifying them, which helps reduce accidental changes in important files.
Diagram and drawing tools : Create Mermaid diagrams and Excalidraw-style visuals for architecture, flows, mockups, and planning with AI-assisted editing.
Developer workspace : Use a Monaco code editor, integrated terminal, git diffs, branch management, worktrees, and AI-assisted commit messages without leaving the app.
Task and plan tracking : Track tasks, bugs, ideas, and decisions in markdown-backed plans that both humans and agents can read and update.
MCP and skills support : Connect agents to external services through Model Context Protocol and use slash commands or custom skills for repeatable workflows.
Local-first and open source : Content lives in standard local files, with open-source licensing for the desktop app and team collaboration layer.
Pros
✔ Strong fit for developers who use Codex, Claude Code, or multiple coding agents.
✔ Local-first file storage gives users more control over project data and history.
✔ Visual diff review makes agent edits easier to inspect before committing.
