A customdomain.ai alternative: DoDomain vs customdomain.ai
customdomain.ai and DoDomain are in the same lane: both get the DNS record written inside the customer's own DNS provider rather than asking them to copy it, and both verify before go-live. The differences are the shape of the free tier, how connections are metered, how often drift is checked, and whether the vendor is willing to be your edge. This page sticks to what each site publishes.

Pricing at a glance
| DoDomain | customdomain.ai | |
|---|---|---|
| Free tier | $0 forever — 50 verified connections per month, no card | Starter — free, 10 domain connections per year, no card (per customdomain.ai and customdomain.ai/pricing, retrieved 2026-09-02) |
| First paid tier | Pro — $29/mo, 500 connections/mo | Startup — $149/mo, 600 connections/yr (per customdomain.ai and customdomain.ai/pricing, retrieved 2026-09-02) |
| Next tier | Scale — $99/mo, 2,500 connections/mo, unlimited apps | Growth — $649/mo, 600 connections/yr plus overage in 1,000-domain blocks; adds a reverse-proxy edge and automatic HTTPS (per customdomain.ai and customdomain.ai/pricing, retrieved 2026-09-02) |
| Top tiers | Enterprise volume by contact — no quote-only feature tier | Premium (12,000/yr) and Enterprise (12,000+/yr, white-label, domain resale) — custom pricing (per customdomain.ai and customdomain.ai/pricing, retrieved 2026-09-02) |
| Metered by | Verified connections per month — a connection counts once, on its first verification; no overage billing, a hard cap instead | Domain connections per year; "no metering" within a tier, overage blocks above Growth (per customdomain.ai and customdomain.ai/pricing, retrieved 2026-09-02) |
Read the meters side by side before the prices: DoDomain counts per month and refuses new sessions at the cap rather than billing overage; customdomain.ai counts per year. A product onboarding 40 customers a month sits inside DoDomain's Freeplan and outside customdomain.ai's Starter tier in its first week.

Verified, not just applied
The Domain Connect protocol has a structural gap: a DNS provider that accepts a signed apply has no way to tell the service provider whether the write actually landed. Any product that treats the apply redirect as success is trusting a callback. DoDomain reads the domain's authoritative nameservers on every path — OAuth, Domain Connect, manual — and only then records the connection, meters it, and signs the connection.verified webhook. customdomain.ai states that records are verified before go-live; its pages do not describe the mechanism, so we compare only what is published.
Where customdomain.ai still wins
Honest flip side. customdomain.ai will be your edge if you want it to: from its Growth plan it serves customer domains from a reverse proxy with automatic HTTPS, and its Premium and Enterprise tiers add fleet-scale monitoring policies, white-label branding and domain resale (per customdomain.ai and customdomain.ai/pricing, retrieved 2026-09-02). It also lists a wider record vocabulary per connection — A, CNAME, TXT, MX, SPF and DKIM — where DoDomain ships one record per session today, with multi-record sessions in progress. If you want one vendor to write the DNS, terminate TLS and set up email records in a single flow, that is a real difference in their favour.
Where DoDomain earns its place is a free tier measured in months rather than years, self-serve pricing with no overage, drift checks every 10 minutes rather than hourly right after setup, Domain Connect templates that are registry-merged and provider-proven, and an architecture that is never in your request path.
Frequently asked questions
What does customdomain.ai cost?
As published on customdomain.ai/pricing (retrieved 2026-09-02): Starter is free with 10 domain connections per year; Startup is $149/month with 600 connections per year; Growth is $649/month with 600 connections per year plus overage in 1,000-domain blocks and adds a reverse-proxy edge with automatic HTTPS; Premium (12,000/yr) and Enterprise (12,000+/yr) are custom-priced. Check customdomain.ai for current figures.
How does DoDomain's free tier compare?
DoDomain's Free plan is $0 forever with 50 verified connections per MONTH and the complete product — every connect tier, authoritative verification, signed webhooks and drift monitoring — with no card. customdomain.ai's Starter tier is free with 10 connections per YEAR (per customdomain.ai and customdomain.ai/pricing, retrieved 2026-09-02). Over a year that is 600 connections on DoDomain against 10.
Do both products write the DNS record for the end user?
Yes, that is what makes this a head-to-head. customdomain.ai describes "OAuth where it exists, a scoped token, or a guided step everywhere else" across 63 auto-configured providers (per customdomain.ai and customdomain.ai/pricing, retrieved 2026-09-02). DoDomain writes through a scoped Cloudflare OAuth grant, through a signed Domain Connect apply wherever the user's provider has enabled DoDomain's registry-merged templates, and guides provider-specific records everywhere else — then reads the authoritative nameservers before declaring success on every path.
How does drift monitoring differ?
customdomain.ai states it re-checks every hour and re-issues on change (per customdomain.ai and customdomain.ai/pricing, retrieved 2026-09-02). DoDomain re-checks every 10 minutes for a connection's first day, hourly for a week, then every 6 hours; a suspected drift is confirmed on three consecutive checks before the connection flips to broken and connection.failed names the exact failing records; recovery re-emits connection.verified. It is free on every DoDomain plan with no monitored-domains cap; customdomain.ai lists drift detection on every plan and "fleet-scale monitoring policies and alerting" from Premium.
Does DoDomain serve customer domains from an edge like customdomain.ai's Growth plan?
No, by design. DoDomain never proxies traffic and never holds certificates — DNS points at your own host and TLS terminates there (Vercel, Cloudflare for SaaS, Approximated, Caddy, nginx). customdomain.ai offers both modes: serving customer domains from its edge, or verifying and handing DNS back to your stack (per customdomain.ai). If you want the vendor to be the edge, that is a real difference in their favour.
Which one is more proven on the Domain Connect protocol?
We can only document DoDomain's side: both of its Domain Connect templates are merged into the public Domain Connect registry, and both have completed real signed applies end to end on live third-party providers — the provider wrote the record, DoDomain verified it at the authoritative nameservers, and the signed webhook fired. customdomain.ai's pages do not describe its Domain Connect status, so this page makes no claim about it.
