register

is-a.dev is a free service that gives developers a personal subdomain under the .is-a.dev domain name. Instead of paying for a domain like yourname.com, you can register yourname.is-a.dev at no cost and point it at your personal website, portfolio, or project page. The subdomains are intended for individual developers and personal use.

To claim a subdomain, you fork this GitHub repository, add a small configuration file describing the DNS records you want, and open a pull request. Volunteers review the request and, once approved, merge it. The DNS records then go live within a few minutes, handled automatically through Cloudflare, which sponsors the service.

The project is community-run and relies on manual review of each pull request. The README warns that pull requests generated by AI tools or submitted in bulk are treated as spam and will be closed. The team can also block repeat offenders and remove existing subdomains if the content they point to violates the terms of service.

A Discord server handles announcements, service updates, and downtime notifications. Not all updates appear on GitHub, so the Discord is the main channel for staying informed about the service.

The repository itself mostly contains the DNS configuration files that represent every registered subdomain, one file per subdomain. There is no software to install or run. The whole system is a GitHub-based registration process backed by Cloudflare DNS management.
