Free Custom Domain Cost Calculator
Estimate what it would cost to ship per-customer custom domains in-house — engineering setup, ongoing maintenance, edge infra — vs. paying for a managed service like Domainee.

How it works
Set your scale
Number of customer hostnames you expect, and roughly how much bandwidth each customer pulls per month.
Tune the DIY assumptions
Engineering setup, monthly maintenance, hourly rate, and infra cost. Defaults are conservative for a real production-grade build.

Side-by-side monthly + horizon cost. Where the lines cross tells you when build-vs-buy flips.
Frequently asked questions
Are the DIY hours realistic?+
The defaults (200 setup hours, 8 maintenance hours / month, $150/hr) reflect a midsize team that needs to build TLS issuance, edge routing, DNS validation, status reporting, and webhooks. Smaller teams hit much higher numbers; ex-FAANG infra teams hit lower.
What's the actual managed pricing?+
Domainee: first 20 hostnames and 100 GB / month free. Then $0.20/domain/month graduated down to $0.10 at scale, and $0.05/GB above 100 GB. No setup, no contract.
Does this include cert costs?+
Yes — managed pricing includes TLS issuance and renewal. The DIY 'infra' line covers the typical mix of an NLB/ALB, an ACM-style cert pipeline, and monitoring.
What if I already have an edge?+
Then DIY is much cheaper than the default. Drop 'Monthly infra' and most of the setup hours — and the calculator updates immediately.
