- Browser-based sandboxes run lightweight front-end code directly in the browser, with automatic previews syncing to code changes, and browser devtools (console) available inside the editor .
- Embeds enable you to include a running sandbox in documentation, blogs, or websites with customizable options (editor size, theme, modules, highlighted lines) .
- Supports Medium embeds by simply pasting the sandbox URL, and the embed application is built specifically to be as small as possible for fast loading .
- Offers a range of embed parameters including autoresize, Codemirror (smaller editor), highlights, module selection, and preview window options .
- Browser Sandboxes are limited to front-end code; features like live sessions, full VS Code integration, and terminal access are only available on VM Sandboxes .
- Some advanced features like high-performance back-end environments or full-stack applications require VM Sandboxes, which are not as lightweight .
- The embed does not include all features of the full editor, and some options (like eslint or runonclick) require manual configuration .
