A service that provides free subdomains for personal sites, open-source projects, and other developer use cases, historically managed through GitHub pull requests. The GitHub-based registration flow has been deprecated in favor of a new platform at open-domains.com.
Use cases
- get a free subdomain for my personal site
- free domain for my open-source project
- host a github pages site on a custom subdomain
- free subdomain with cloudflare dns
- register a free domain as a developer
When to choose
- you want a free subdomain for a personal website or open-source project
- you already use GitHub Pages or Cloudflare and want a custom hostname
- you want to avoid buying a domain for a hobby project
When to avoid
- you need a full top-level domain rather than a subdomain
- you require guaranteed long-term availability, since the GitHub flow is deprecated and some domains are shutting down
- you need commercial or production-grade domain services with SLAs
