Edge
DNS + tunnel + TLS proxy. Start with a hostname attach; authoritative DNS is available when you want it.
The agent opens an outbound tunnel. The edge terminates HTTPS and forwards through it to your origin.
DNS · tunnel · TLSConnect an app you already run.
Your AI can put your app on FastDog safely in one prompt.
No inbound ports. Connect codes expire in an hour. Paid-plan API keys expire after 30 days by default; a trial key expires at the trial end.
Add your hostname and two DNS records, then paste one prompt into your coding assistant. It connects your server to FastDog over an outbound tunnel, with HTTPS on your own domain.
Your app must already be running on a server you control.
Free for 7 days on one hostname. No card.
On day 8 the hostname pauses until you pick a plan. Nothing is deleted.
Who it’s for
For people building and running their own apps.
Vibe-coders
You built the app. Connect the server where it runs, and give it an HTTPS address.
People using AI coding assistants
Give your assistant a scoped setup prompt. Keep account access and command approval with you.
Indie SaaS builders
Start with one hostname, keep your DNS provider, and connect your existing app.
For HTTP apps you already run. No WebSockets or server-sent events (streaming responses); requests up to 30 seconds and request bodies up to 50 MiB. See the current limits.
Portal setup
Add your address, then connect your server.
Sign up and verify your email. On Website, add your address, add the CNAME and TXT records at your DNS provider, and verify the address.
Once the address is verified, open Server, enter your app’s address, and select Create prompt. Paste the prompt into your coding assistant and review the connection command before approving it. Then check that your app loads over HTTPS.
Follow the AI assistant setup guide for the full instructions.
For AI coding assistants
Let your coding assistant do the setup.
Give your assistant a token scoped to one verified hostname. Keep account access and DNS changes with you.
Copy a prompt. First add your hostname in the portal, add the CNAME and TXT records at your DNS provider, and verify the address. Then on the Server page, press Create prompt under “Copy prompt for your AI assistant.” Paste it into Claude Code, Cursor, Codex, or whatever you use. The assistant uses that prompt to connect your server.
A scoped connection token. The prompt carries a connect-only token for one verified hostname. It expires after one hour and can be revoked from the Server page. It cannot create a hostname or manage DNS. The agent key is saved on your server. Getting a new connect command replaces it and closes the old connection, and you can revoke it anytime.
Docs your AI can read. Plain guides at /llms.txt for the assistant and the docs for you, so it follows the steps instead of guessing.
What you still do. Keep account access and DNS changes with you. Review and approve the connection command. Your password and sudo prompts stay with you.

What we run
DNS, app connections and bot decisions.
Domains
Registered at cost, in your name.
You are the registrant. Then attach a hostname to the edge.
Verdict
Early access
Allow / challenge / block at the edge. On customer hosts it runs in shadow mode: it shows what it would decide and never blocks.
Verdict runs on the edge server itself, so each decision is a local call, not a trip across the internet.
Live health
What you keep
What you keep control of.
Your registrar and your DNS
Attach uses one CNAME at your current DNS host. Your domain stays registered where it is, and your other records stay as they are.
Your app and its ports
Your service keeps running where it runs. The agent connects out to the edge, so you don't open inbound ports for it.
Detach any time
Remove the CNAME and traffic for that hostname stops coming to FastDog. Tell us, and we remove the hostname and its agent credential on our side.
Only the hostname's edge
FastDog handles TLS, the proxy, and the tunnel for the hostnames you attach.
Add your hostname yourself: sign up in the portal and add it there. Need help? Email support@fastdognetworks.com. Agency plans get a same-business-day first reply.
Customer story
An app connected through the edge.
An independent time-keeping app uses a domain registered through FastDog Domains and one hostname attached with a CNAME.

Fair use applies. If your traffic outgrows a plan, we'll talk before anything changes.
Free for 7 days on one hostname. No card. When you're ready to pick a plan, email support@fastdognetworks.com from your account's email address.
Setup guarantee
Our promise.
- On the Agency plan: same-business-day first reply (America/Denver).
- Guided setup: once your CNAME (or nameservers) points at FastDog and we have a working origin, we'll agree a cutover date with you.
- If it doesn't work out, remove the CNAME (or we help flip nameservers back) and we remove the hostname on our side.
How to start: sign up in the portal and add your hostname. For guided setup, email support@fastdognetworks.com with the hostname, where your DNS lives, and where the origin runs.
