I wanted a way to work with Claude Code and Codex with higher bandwidth. So I built Nimbalyst, an open-source local-first visual workspace:
Agents edit the same files you do, in visual editors for markdown, mockups, diagrams, data models, and code
Agent changes show up as red/green diffs with per-block accept/reject
Sessions, files, and tasks are linked, so you can trace work across them
Parallel sessions are managed on a kanban board instead of buried in terminal tabs
Tasks live in the same workspace as the agent, so plans, bugs, and work stay linked to sessions and files
Developer workflow features like worktrees, workstreams, visual git management, and agent git proposals
Today it supports Codex and Claude Code. Opencode and Copilot are in alpha.
A few details:
Local-first, files stay on your filesystem in open formats
MIT for desktop and the iOS app for remote session management and soon file management
AGPL for the collaboration server
Extension system for custom editors and tools that are agent-native and integrated
Tech stack: Electron, React, Jotai, PGLite, Lexical, Monaco, Playwright.
I'd love to work on this with you.
