Why Nimbalyst?
Nimbalyst is an open-source visual workspace for Claude Code and Codex. Learn what it does, who it is for, and how to start working with AI agents.
Nimbalyst is the open-source visual workspace for building with Claude Code, Codex, and other coding agents. It runs on your Mac or Windows machine on top of the agents you already have installed, and it gives you visual editors, session management, and task tracking in one app. Use it when you want to direct and review agent work without bouncing between a terminal, an editor, a document app, and a task tracker.
Download Nimbalyst and open a project folder to get started. Your project files stay in your folders in open formats. Features such as AI requests, sharing, and sync use the services you configure; see Privacy. The full source is on GitHub at github.com/nimbalyst, where you can read the code, file issues, or contribute.
One integrated, higher-bandwidth workflow
Building with agents is a whole workflow. It moves through plans, source files, mockups, diagrams, data, tasks, sessions, reviews, commits, and pull requests. Nimbalyst keeps that work together so people and agents can move through it as one connected process.
Integrated workflow: Plan the work, run agents, edit the result, track status, review changes, and connect the commit without rebuilding context in another tool.
Integrated file types: Work in purpose-built visual editors for markdown, code, mockups, diagrams, spreadsheets, data models, and more while the same agents stay in context.
Less context switching: Stop bouncing among a terminal, editor, document app, diagram tool, and task tracker, or copying the same context into each one.
Higher bandwidth: Visual interfaces expose more of the work at once, so people understand, direct, and review agent output faster than they can through a text-only workflow.
Files Mode
Work with Claude Code and Codex in interactive, WYSIWYG markdown docs, Calc Sheets, mermaid diagrams, excalidraw drawings, html mockups, data models, CSV files, in-app browser previews, mind maps, sessions, and code.
Focus on one file:
Edit the file in the center panel. See red/green diffs from your coding agent, review them, and accept them.
Work with your agent in the right panel to edit this file, explore other files, or research the web.
Navigate and manage your files in the left panel file manager.
Span several folders and repositories in one project with multi-folder projects. Attached folders appear in the explorer, in search, and to your agents, with git status, branches, and commits tracked per repository.
Agent Mode
Session management: organize, find, and continue your AI conversations. Track the files changed by a session and step through and approve each one.
Coding support: all the power of Claude Code and Codex plus file tracking, diff visualization, code editing, and / command support with GitHub status tracking.
Files where you want them: choose whether Agent mode opens file tabs above the transcript or in the right pane. See View Files in Agent Mode.
Model choice: choose an available model and reasoning level in the session composer. The options depend on the provider and your configuration.
Task Mode
Status and item tracking: you and your agents track and update status, bugs, to-dos, decisions, and ideas directly in markdown associated with the plan and the work.
Radar: shared trackers get a since-you-left digest of teammate activity, status moves, bulk sweeps, and stalled work, in the desktop app and the web console. See Radar.
Team Collaboration
Every teammate runs the open-source Nimbalyst app on their own machine with the Codex, Claude Code, or other agents they use locally. After signing in to Nimbalyst Teams, they can promote local files into a shared team workspace and keep working with those agents.
People and their agents can edit shared files together in real time or contribute asynchronously. Shared Trackers work the same way: teammates and their agents update one team board from their own Nimbalyst installations. Only files and Tracker items explicitly shared with the team enter this collaboration flow; everything else stays outside the team workspace.
Shared team data flows through Nimbalyst's Cloudflare sync service. It is encrypted in transit and at rest and isolated per team.
See Nimbalyst for Teams for what the shared workspace covers.
Ask questions of your team from inside a shared document: decision blocks collect answers next to the options, and feedback requests let an agent gather private answers from teammates and resume once a human settles the outcome. Sent questions appear in Feedback with response progress and links back to each one.

Project Graph
Look at the graph Nimbalyst builds underneath your project, connecting sessions, trackers, files, and commits. The Atlas, Pulse, and Evidence Trails views show what you worked on, what is connected to what, and the sources behind every link, with saved views and time-range comparison. See Project Graph.
Open Approach
Open source: the Nimbalyst app itself is open source at github.com/nimbalyst.
Open storage of content and status in markdown, code, and html:
Future-proof: your files will be readable in any text editor, forever.
Portable: move between different markdown tools without conversion.
Version-control friendly: works with Git and other VCS.
LLM-friendly: work with Claude Code, Codex, and any AI.
Open storage of workflow and config in coding agent skills and commands.
Open storage of your files in your file tree or GitHub.
