Free subdomains for everyone – no catch, no cost.
Open-Domains is a community project offering free subdomains on open.domains. There’s no registration form – just fork our GitHub repo, request your subdomain, and you’re live.
domains.json
.{
"example": {
"A": ["1.2.3.4"],
"CNAME": ["example.github.io"],
"MX": ["mx.example.com"]
}
}
Currently, Open-Domains offers subdomains under the following domains:
"Thanks to Open-Domains, I launched my project in minutes." – Alex
"A fantastic resource for students and hobbyists!" – Jamie
"Setup was simple, and it's completely free." – Pat
Open-Domains is a volunteer-run project inspired by the spirit of open source. Our goal is to give developers and hobbyists a place to host their websites, experiments, and portfolios without having to pay for a domain.
We use the Public Suffix List to help ensure each subdomain behaves as an isolated identity. This is important for web security and cookie sandboxing.
Thanks to Cloudflare, all DNS records are powered by fast, secure infrastructure. We are proud to be a sponsored partner.
