Why Nimbalyst?
Nimbalyst is the open-source visual workspace for building with Codex, Claude Code, and more.
Get higher bandwidth with less context switching. Manage your agents, edit the work visually, and track tasks.
Work across markdown, Calc Sheets, mockups, diagrams, diffs, code, and more without leaving the workflow or rebuilding context.
Nimbalyst stores your files and data locally in an open format. 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 and review, accept them.
Work with your agent in the right panel to edit this file or explore other files, research the web.
Navigate and manage your files in the left panel file manager
Agent Mode
Session Management: organize, find, and continue your AI conversations. Track the files changed by a session and coordinate your stepping through and approving 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.
Task Mode
Status & Item Tracking: AI track and update status, bugs, to-dos, decisions, ideas directly in your markdown associated with the plan/work.
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.
Nimbalyst for Teams is coming soon and currently in early access. Pricing is TBD per user/month. Join the waitlist for pricing and feature announcements.
