ℹ️ О Тестер встраивания
The Embed Tester helps you create high-quality output on demand, for free, right in your browser. Test if any URL can be embedded in an iframe. Check X-Frame-Options and Content-Security-Policy headers. Our Embed Tester uses smart defaults but lets you customize every setting so the final result fits your project. Because everything runs client-side, your inputs and generated outputs remain private — nothing is uploaded or logged. Use it as often as you like, in personal or commercial projects, with no attribution required.
💡 Примеры использования
💎 Советы профессионалов
- Tweak the settings one at a time so you can see how each option affects the Embed Tester output.
- Click the regenerate or randomize button multiple times — you often find a better result on the third or fourth attempt.
- Copy several candidates to your clipboard or a notes file and compare them before committing to one.
- If the Embed Tester supports exporting, save important outputs immediately — nothing is persisted server-side.
- Combine outputs from this Embed Tester with other tools (formatters, previews, checkers) to polish the final result.
