cool but personally $11-15 a year for my own domain in cloudflare is pretty affordable.
i can have my own subdomains, access control with zero trust, reverse proxy via tunnels. metrics, bot fighting and routing rules, free storage, free serverless workers, free static deployments.

Thanks for sharing, man! I didn’t know about this :)
I’ve shared it in my community.

Just tried it so you don’t have to. Not worth it IMO.
Basically you have to fork their repo just to add a tiny JSON file containing with your github username, unobfuscated email address or a social media handle, an existing completed website that’s hosted on either github pages, cloudflare pages, vercel, netlify or one of their supported providers. You can’t add your own NS record unless you get in touch with them. Well the rest of the process isn’t automated either, since your PR will be reviewed by a maintainer who’ll decide if your website is good enough or not.
TL;DR: it’s an absolutely overengineered way to ask a bunch of strangers if they can point one of their subdomains to your site, which they can take away anytime they want. Similar to <a href="https://github.com/abint7/free-domains?tab=readme-ov-file" target="_blank" rel="noopener nofollow">these providers</a> except the registration is not even automated. You’re much better off with the other providers in that list.

Can anyone tell me how this technology works?
I mean that how they are providing this domain.
If possible, can anyone tell me about the logic behind this project?
Thanks

If I go through the domains directory and open few json files I see lot of personal identifiable data like their email and username etc
And it’s a public repository too
Is this secure ? On that front
