A subdomain for $5. One-click DNS. Auto-expires in 30 days. Namecheap charges $9/year and makes you do DNS by hand. We charge $5, once, and your subdomain quietly disappears when you're done with it.

→ Visitor #42 today · 🔐 password protected
→ Expires in 28 days (renew: POST /api/renew)
Three steps. Total setup time: about the time it takes to read this paragraph.
Anything not already taken. We bind it to yourname.sn-x.com under Cloudflare's DNS in milliseconds.
One input box. Drop your Glitch link, GitHub Pages URL, even an IP. Changeable in one click anytime you want.
Visitor counter, password gate, auto-redirect, "coming soon" splash — toggles, no config files. They come with the listing.
Forget to renew? No pestering emails, no $80 "redemption" fee. It just stops. That's the whole point.
Every subdomain ships with these toggles. No upsells.
Point your subdomain anywhere with a single text field. Cloudflare Workers handle the proxy, HTTPS, and routing — all free tier.
Set one password. Visitors see a clean gate before reaching your destination. Perfect for previews, beta cohorts, invite-only events.
Send visitors to a specific path on your target URL. ?utm_source=burn tagged by default — track conversions from your subdomain.
See exactly how many people hit your subdomain, where they came from, and what device they used. Real-time, public, or private.
30 days. No renewal emails, no charge attempts, no "we'll charge your card on file" surprises. It just resolves to nothing.
$5 buys you a subdomain for its lifetime — until expiry. Renew for $3 if you want to extend. No subscriptions ever.
Honest math, no asterisks.
For comparison: a single subdomain on Namecheap is $9/year minimum, requires manual nameserver config, and renews at full price annually. We charge $5 once — not per year — and never auto-renew.
Anyone shipping something short-lived needs one of these in their toolbox.
Subdomain for every team. Bracket site, judging portal, results page.
Private invite links without exposing infrastructure. Password-gated by default.
Wedding, conference, popup — point to your Tally/Notion page. Live for the day, gone after.
"Mything.mything.com" without the $9 annual commitment before you've even validated the idea.
Pretest survey, paper companion site, replication link. Auto-expires when grant ends.
Flash drop landing page with visitor counter for hype. DNS rebinds when drop changes.
Things people actually ask.
Because you don't need one. Subdomains inherit the parent's authority, HTTPS coverage, and Cloudflare protections. For anything short-lived, a subdomain is functionally identical to a $14/year domain, costs $5 once, and disappears cleanly.
DNS records are removed. The subdomain stops resolving. We hold the name for 30 days after expiry in case you want to renew — then it's released for anyone to claim.
Yes. Export your full configuration — target URL, easter-egg toggles, visitor analytics — and re-import into any other subdomain in one click.
You do. Export anytime as CSV. We don't sell it, mine it, or share it. Ever.
Subdomains on a domain you own are 100% normal, common, and explicitly supported. We run on Cloudflare's free tier (Workers + KV + Pages). No ToS risk.
Names auto-release on expiry. Squatting costs them $5 per name per month. Not profitable.
$5. One time. Done when you're done.
