About CodeSandbox Watermark Minimizer
CodeSandbox Watermark Tiny is a lightweight developer utility that reduces visual clutter on CodeSandbox preview pages (*.csb.app) by removing the default “Open Sandbox” overlay and adding a minimal “dev” button in the bottom-right corner.
What it does:
- Removes the injected watermark iframe overlay on CodeSandbox preview pages.
- Adds a tiny, rounded white “dev” button with a small screen margin so it won’t cover your content.
- Keeps one-click access to the corresponding sandbox page by mapping https://{id}.csb.app/... → https://codesandbox.io/s/{id}.
Why install:
- Cleaner screenshots/recordings for demos.
- Less obstruction for mobile and small-screen previews.
- Faster access to the sandbox source via a consistent “dev” link.
Notes & transparency:
- Works only on CodeSandbox preview domains (*.csb.app).
- This extension modifies page UI locally in your browser; it does not change the hosted site for other users.
- It does not collect, store, or transmit personal data.
