SHIP_IT
DEPLOY_ANYWHERE
Point your domain at the platform you already build on
CLOUDFLARE_WORKERS
Add the CNAME your Worker gives you as a record in the console, and your project answers on your own name. Edge code on a domain that cost you nothing.
VERCEL_PROJECTS
Attach the domain to your Vercel project: add the record Vercel shows you, verify, and your deployment gets a production address you actually own.
NETLIFY
Netlify hands you a netlify.app URL and a DNS target. Add the target as a CNAME record, or an ALIAS if you want the bare domain, paste your name into Netlify's domain settings, and certificate renewals take care of themselves from there.
GITHUB_PAGES
Point a CNAME at your Pages site, or A records at GitHub's addresses if you want the apex. Set the custom domain in your repo settings, flip the enforce HTTPS switch, and your README project has a real address.
CLOUDFLARE_PAGES
Every Pages project gets a pages.dev subdomain; your name can replace it. Add the CNAME the dashboard suggests, attach the domain in your project settings, and certificates are issued for you without a ticket or a form.
FIREBASE_HOSTING
Firebase asks for a couple of A records, or a TXT record to prove the name is yours, then provisions a certificate and starts serving. The console shows exactly what to paste, one value at a time.
YOUR_OWN_SERVER
A 1-core, 512 MB RAM, 5 GB disk box with a single IPv6 address is already a server. Point an AAAA record at it (or an A record for IPv4), and the learning starts: no platform in the middle, just you, your ports, and everything this project was founded to teach. No hardware yet? A free Light Server is one request away, below.
// every platform above starts the same way: one record in the console. what happens next is their job, and they are good at it.
LIGHT_SERVERS
A_BOX_OF_YOUR_OWN
A free IPv6-only machine for every active community member
$ lights spec --free
vCPU 1 shared core
MEMORY 512 MB
DISK 5 GB
NETWORK 1 public IPv6 address
RENEWAL community points, auto monthly
$ echo $COST # 0.00, forever
$
REAL_MACHINE_REAL_ADDRESS
A small but real computer with a public IPv6 address of its own: enough for a blog, a practice mail server, a bot, or your first containers. It stays free for as long as you stay active in the community: a small number of points a month, earned by posting build logs and answering questions. Miss a month and it pauses instead of deleting; your disk waits up to 60 days, and the same machine comes back exactly as you left it.

FAQ
FREQUENTLY_ASKED
Everything about claiming your free domain
Is it really free?
Yes, and it has been since the project launched on January 1, 2025. Public Free Suffix is a non-profit, community-run service: no annual fee, no trial period, and no hidden cost. A claimed name stays free for as long as you use it.
Who can register a domain?
Anyone with a GitHub account that is at least two years old. Create an account in the domain console, verify your GitHub profile, and claim your name. Verification keeps the zone safe for everyone.
What names can I take?
One label under the suffix: myname.is-a.si works, my.name.is-a.si does not. The name must not hit the reserved words list, and standard trademark rules apply.
How does DNS work?
Every domain comes with SEUS DNS, our global resolution service. You manage your records in the same console: A, AAAA, MX, NS, CAA, TXT, CNAME, ALIAS, HTTPS, and more. No third-party DNS setup, nothing to delegate.
Can I connect my domain to Vercel or Cloudflare Workers?
Yes. Add the record your platform gives you (CNAME, A, or AAAA) in the console, then verify the domain on the platform side. Vercel, Netlify, Firebase, GitHub Pages, Cloudflare Pages and Workers, or a box under your desk: if it takes a DNS record, it works. ALIAS and HTTPS support makes apex setups easy too.
What happens if I stop using my domain?
Please deploy something within 30 days. Domains held for 30 consecutive days without content are reclaimed, so the names go to people who actually use them.
Applied through a GitHub pull request before?
The PR flow has been retired; registrations now run through the web console. Your suffix priority is preserved: sign in with your original Whois email and your domain will be waiting. Allocations began October 7, 2026.
What is not allowed?
Phishing, fraud, gambling, pornography, malware, trademark impersonation, and anything else the Acceptable Use Policy prohibits. Violations are taken down without compromise, and you can report abuse online or by email.
