Comparison - Visual workspace for coding agents

Winy vs Nimbalyst

Nimbalyst wraps your agents in visual editors, diffs and a session kanban; Winy puts them as cards on a canvas you write and draw on.

Nimbalyst is a free, open-source desktop workspace for Claude Code and Codex on macOS, Windows and Linux, with visual editors for Markdown, mockups, Excalidraw and Mermaid diagrams, data models and spreadsheets, and an agent panel beside them.

It is organized around files and sessions: every AI edit shows up as a diff you approve, sessions sit on a kanban from backlog to complete, and each session can get its own Git worktree.

Winy is a canvas notebook for Mac, iPad and iPhone, where real agent sessions sit on an infinite board as live cards beside your notes, Pencil ink, arrows and images, so the layout of the board is the plan.

Which one is for you

Choose Nimbalyst if

You want to review every agent edit as a red and green diff before it lands, and track sessions on a kanban from backlog to done.
You plan in documents: Markdown specs, UI mockups, data models and diagrams that the agent edits alongside your code.
You want it free and open source under MIT, on Windows or Linux as well as the Mac.
You want optional Git worktree isolation per session and AI-written commits built in.

Choose Winy if

You think spatially, with notes, arrows and Pencil ink laid out on one infinite board, and want the agents sitting on that same board, seeing it.
You want the full board on your iPad and iPhone, not only a session list, with sync over your own network and no cloud relay.
You want to see every agent at once, with status lights and a one-line summary per card, and drop a live terminal or browser anywhere on the board.
You already run Claude Code in a terminal and want Winy to attach to those sessions, with pickers as buttons.
