How to get a working domain without buying one (5 methods)

You need a hostname for local dev. Ingress rules require one. A real domain costs roughly ₹500-1,500/year depending on TLD and registrar. Here are 5 free methods that work today.

Method 1 — nip.io / sslip.io (public magic DNS)

Free public DNS service that resolves any hostname of the pattern:

<anything>.<ip-with-dashes>.nip.io

If your minikube IP is 192.168.49.2:

myapp.192-168-49-2.nip.io → resolves to 192.168.49.2
dashboard.192-168-49-2.nip.io → same
db.192-168-49-2.nip.io → same

Zero setup. Works from any machine. No signup, no config.

Use in Ingress:

- host: hello.192-168-49-2.nip.io

sslip.io = identical mirror service. Interchangeable.

Method 2 — Local hosts file (works offline)

Only YOUR machine sees the domain.

Windows: C:\Windows\System32\drivers\etc\hosts (needs admin) Mac/Linux: /etc/hosts (needs sudo)

Add:

192.168.49.2   myapp.local
127.0.0.1      dashboard.local

Browser now resolves myapp.local to 192.168.49.2.

Pro: offline, permanent, personal
Con: only you see it. GitHub webhooks can’t reach it.

Method 3 — dnsmasq (custom domain for whole machine)

For a real-looking custom domain across your machine, without editing hosts per-app.

Install:

brew install dnsmasq        # Mac
sudo apt install dnsmasq    # Linux

Config (Mac path):

address=/.mycompany.test/192.168.49.2

Restart dnsmasq. Now anything.mycompany.test resolves to 192.168.49.2 automatically.

Pro: clean hostnames like argocd.mycompany.test
Con: setup complexity, only your machine

Method 4 — Cloudflare Tunnel (real HTTPS public URL)

Turns a random-name.trycloudflare.com URL into a public HTTPS tunnel to your local service.

Install:

brew install cloudflared        # Mac
winget install Cloudflare.cloudflared    # Windows

Run:

cloudflared tunnel --url http://localhost:80

Prints URL like https://random-name-1234.trycloudflare.com. Real internet-reachable.

Pro: real HTTPS, GitHub webhooks work
Con: URL changes on restart with the default --url mode. For stable hostnames, use a named Cloudflare Tunnel — included FREE in Cloudflare Zero Trust (up to ~50 seats), requires only a domain added to Cloudflare with its nameservers.

Method 5 — ngrok

Same idea as Cloudflare Tunnel.

ngrok http 80

Prints https://xxxx.ngrok-free.app URL.

Pro: works instantly
Con: needs ngrok account signup, URL changes on restart

Which method for which use case

Use case	Method
Just see it in your browser	nip.io or hosts file
Other people (same wifi) should see it	nip.io
Real HTTPS for external testing	Cloudflare Tunnel
GitHub webhook back to your local machine	Cloudflare Tunnel or ngrok
Custom domain names, multi-app dev	dnsmasq
Something you’ll re-use for years	Buy a real domain

Local-only trick — localtest.me

*.localtest.me always resolves to 127.0.0.1. Similar to nip.io but hardcoded to localhost.

Ingress:

- host: hello.localtest.me

Browser: http://hello.localtest.me → hits 127.0.0.1.

The subtle gotcha nobody mentions

Your Ingress ADDRESS matters more than the hostname. Check:

kubectl get ingress

Look at ADDRESS column:

192.168.49.2 → use myapp.192-168-49-2.nip.io
127.0.0.1 → use myapp.127-0-0-1.nip.io

Hostname must resolve to whatever IP your Ingress is exposed on. Otherwise browser can’t reach it even though the ingress is technically working.

When you SHOULD buy a real domain

For production. Users need to bookmark and trust the URL. Cloudflare / Namecheap / Porkbun sell for ₹500-1,500/year.

Then point DNS A record at your cluster’s LoadBalancer IP → cert-manager gets a real TLS cert → users hit myapp.yourcompany.com.

The Ingress YAML doesn’t change. Only the host: string does.

TL;DR

Local dev: nip.io or hosts file — free, instant
External test/webhooks: Cloudflare Tunnel — free, real HTTPS
Production: buy a real domain — roughly ₹500-1,500/year depending on TLD + registrar

Never buy a domain for local dev experiments. Everything above is free.
