Claim a working subdomain in one call — A, CNAME and TXT records. No domain to buy, no account.
Quick Install
Automated & IDE SetupCopy the AI prompt to install this server into Claude Code, Cursor, or another agent — or use 1-click editor setup below.
One-click editor setup isn’t available for this listing yet — we don’t have a confirmed install command, and we’d rather show nothing than point your editor at the wrong package or host. Follow the project’s own setup instructions, linked above.
Manual Client & Custom JSON ConfigExpand JSON ▾
No confirmed setup config for this listing yet. We only publish a config block when the install details come from the project itself — its README, its docs, or a verified owner. We haven’t found those for Sitey — free subdomains, and we’d rather show nothing than a guess you’d paste into your client. Follow the project’s own setup instructions for the current steps.
Documentation Overview
sitey.my
Free subdomain service for developers. Get a subdomain in seconds — no credit card, no hassle.
Features
- Instant DNS — A, CNAME, and TXT records, live in seconds
- Google sign-in — No passwords to manage
- REST API — Programmatic access via /api/v1/
- Renewals — Subdomains are lent for a period and kept with one click
- Free — No cost, no catch
How long a subdomain lasts
| Owner | Period | Reminders |
|---|---|---|
| Signed-in user | 3 months | 14 days, 3 days and the day it expires |
| API key / agent | 1 month | none — expires_at comes back with every read |
Renewing resets the clock from today. A subdomain that stops loading is not removed: we write to tell you it has gone dark, and that is all.
Quick Start
- Visit sitey.my
- Sign in with Google
- Type a subdomain + IP address → done
REST API
Programmatic access for developers and AI agents.
Base URL: https://sitey.my/api/v1
sitey.one and the www. hosts redirect here (308 for /api/*, so POST bodies survive).
Authentication
| Mode | Auth | Limit |
|---|---|---|
| Anonymous | None (IP-based) | 3 subdomains |
| API key | Authorization: Bearer styo_xxx | Unlimited |
Get an API key: sign in at sitey.my → Dashboard → API Keys.
Endpoints
| Method | Path | Description |
|---|---|---|
| GET | /domains | List available root domains |
| GET | /check/:subdomain/:domain | Check availability |
| POST | /subdomains | Create A or CNAME record |
| GET | /subdomains | List your subdomains |
| PATCH | /subdomains/:sub/:domain | Update record value |
| DELETE | /subdomains/:sub/:domain | Delete subdomain |
| POST | /subdomains/:sub/:domain/renew | Extend before expires_at |
| POST | /subdomains/:sub/:domain/txt | Create/update TXT record |
| DELETE | /subdomains/:sub/:domain/txt/:prefix | Delete TXT record |
Example
For AI Agents (MCP)
AI agents can use free-domain-mcp — an MCP server that wraps this REST API.
Tech Stack
- Runtime: Node.js + Fastify
- DNS: Self-hosted BIND9 (authoritative nameserver)
- Database: MySQL
- Auth: Google OAuth2 + JWT
How It Works
- User (or API call) requests a subdomain
- Server validates input + checks availability
- A/CNAME/TXT record is appended to the BIND9 zone file
named-checkzonevalidates →systemctl reload namedapplies- DNS is live within seconds
We run our own authoritative nameservers (ns1.sitey.one, ns2.sitey.one) — no third-party DNS provider.
Use Cases
- Deploy a side project to
myapp.sitey.my - Give hackathon demos a real URL
- Automate domain setup via REST API or MCP
- Share staging environments with teammates
