Best tunnel service with a reserved subdomain (free + paid options)
Reserved subdomains solve the #1 dev-tunnel pain: a fresh URL on every restart that breaks every webhook integration. We rank the three services that offer reservations on free-tier inclusion, paid-tier price, and how flexible the reservation system is.
lrok
One reserved subdomain on the free plan, kept forever. Pro is $9/mo flat for unlimited reservations. Reservation is per-account; you can use it across machines, across days, across restarts.
wins at
The only major service offering reservations on FREE. Per-account scope is right (works across machines).
loses at
Single edge region (Helsinki); custom domains require Pro tier.
ngrok
Static domains on Pro and above. Setup is mature; the dashboard is polished. Free tier rotates the URL.
wins at
Mature feature set, multi-region edge, large customer base.
loses at
No reservations on free. Static-domain pricing scales with usage tier.
Cloudflare Tunnel
Routes via your own custom domain (sub.yourdomain.com). The "reservation" is your DNS record — as stable as you make it. Trade: requires you own a Cloudflare-DNS domain.
wins at
Reservation is permanent (it is your DNS), unlimited subdomains, $0 if you already use Cloudflare.
loses at
Requires domain ownership + DNS migration to Cloudflare. Not zero-friction.
// verdict
If you don't want to own a domain, lrok is the only service offering reserved subdomains on free. With a domain, Cloudflare Tunnel gives you unlimited reservations at no extra cost.
