Are these tools free?
Yes. Both tools are free, with no account, no email and no usage limit.
Is my code or ZIP uploaded?
No. Both tools run in your browser. Your files stay on your device.
Can I preview HTML on a phone screen?
Yes. The HTML preview shows your page at desktop, tablet and phone widths.
Why is my uploaded website blank?
Usually the ZIP has no index.html at the top, has an extra folder around the files, or holds src instead of the built dist folder. The ZIP checker finds which one.
Do I need to know how to code?
No. Paste or drop your files, and the tool tells you in plain words what it found.
How do I put my page online after?
Publish it on GeminiLaunch. The Free plan gives you up to 3 live sites with free SSL and no credit card.
