Forkshop
A Figma-style canvas for your Next.js project.
Forkshop mounts a sidebar and a canvas inside your app's dev environment. Open multiple viewports of your pages side-by-side, edit text in any iframe and save back to source, and watch your AI assistant make changes in real time — all without leaving your code.
npx forkshop initView on GitHub →Edit text in place
Click any text in the canvas to make it editable. ⌘↵ saves to the underlying TSX file; Esc discards. No round-trip to your editor.
See your agent at work
When Claude (or another agent) edits a file your canvas is showing, Forkshop highlights the change live, with a per-agent color so you can track multiple sessions at once.
