Design visually.
Ship real code.
Scamp is a local-first design tool for designers and developers. Draw rectangles, set flex layouts, and style elements. Your design saves as real TSX and CSS Modules files, stored exactly where you want them.
Real output
Your design is the code.
Every rectangle you draw becomes a real div. Every style you set becomes a real CSS class. Scamp doesn't export or compile, it just writes files. Open your project in any editor and the code is already there, exactly as you'd write it yourself.
Bidirectional sync
Edit code, see it live.
Edit visually, see the code.
Scamp watches your project files. Edit the CSS in your editor, run a coding agent, or change a value directly in the terminal. Scamp picks up the change and updates the canvas instantly. No import step, no sync button. The files are always the source of truth.
Built-in terminal
Run your agent.
Right here.
Scamp has a built-in terminal that opens in your project folder. Run Claude Code, Aider, or any coding agent you already use. The agent reads your project's instructions file, edits your layout files, and Scamp reloads the canvas automatically. No copy-pasting. No context switching.
Opens in your project folder
No setup. The terminal starts in the right place every time.
Reads agent.md automatically
Your project conventions are always in the agent's context.
Canvas reloads on every save
Agent edits show up on the canvas without touching it.
Local-first
No cloud. No account.
Just a folder.
Scamp saves to wherever you tell it. Put your project inside an existing git repo, a client folder, or anywhere on your machine. Every page is just a TSX file and a CSS Modules file. You can open them in VS Code, commit them to GitHub, hand them to a teammate, or ship them directly, no export, no lock-in.
Works with git
Your project is a real folder. Commit, branch, and PR like normal.
No account needed
