DoDomain vs SaaS Custom Domains
SaaS Custom Domains is a proxy platform for branded customer domains: automatic SSL, a WAF, DDoS protection, an edge in 119 locations, and a self-hosted option (per saascustomdomains.com, retrieved 2026-09-02). DoDomain is the DNS layer in front of any of that — getting the record created inside the customer's own DNS provider, proving it is live, and watching it afterwards — and it is never in the request path. This page separates the two halves and says where SaaS Custom Domains is the better fit.

Who does which half
| DoDomain | SaaS Custom Domains | |
|---|---|---|
| Gets the customer's DNS record created | Yes — Cloudflare OAuth one-click, signed Domain Connect apply where the provider has enabled it, guided per-provider steps with a live status per record everywhere else | "Automatic DNS configuration" (per saascustomdomains.com, retrieved 2026-09-02); whether the record is written inside the customer's provider is not stated |
| Proves the record is live | Yes — read at the domain's authoritative nameservers before success is declared | Not stated on the sourced page |
| Terminates TLS on the customer's hostname | Never — traffic goes straight to your host | Yes — automatic SSL/TLS plus custom certificates, WAF, DDoS protection, rate limiting (per saascustomdomains.com, retrieved 2026-09-02) |
| Self-hosted option | Not applicable — nothing to host; DoDomain is a control plane that never touches traffic | Yes, with custom TLS termination (per saascustomdomains.com, retrieved 2026-09-02) |
| Monitoring | DNS drift: every 10 min → hourly → 6 h by connection age, 3 confirmed checks, signed events naming the records; free on every plan | Continuous monitoring of the served traffic, "99.999% uptime guarantee" (per saascustomdomains.com, retrieved 2026-09-02) |
| Entry price | $0 forever — 50 verified connections per month, no card, forever | Free trial (no card), then $29/month for 100 domains — $0.29 per domain, volume discounts up to 50% (per saascustomdomains.com, retrieved 2026-09-02) |
| Metered by | Verified connections per month — a connection counts once, on first verification | Domains served (per saascustomdomains.com, retrieved 2026-09-02) |
| Integration surface | REST API + OpenAPI 3.1, @dodomain/node, @dodomain/connect, @dodomain/react, dodomain-sdk (Python), remote MCP server, signed webhooks | REST API, real-time webhooks, analytics dashboard (per saascustomdomains.com, retrieved 2026-09-02) |
Wiring them together
Take the record value SaaS Custom Domains tells your customer to create, pass exactly that record to POST /api/v1/sessions, and hand your customer the returned connectUrl — or embed the @dodomain/connect sheet in your own onboarding. When the signed connection.verifiedwebhook arrives, the record exists at the customer's authoritative nameservers and the edge can serve the hostname. Nothing about your proxy — hosted or self-hosted — changes; DoDomain only replaces the copy-and-paste screen and adds the proof.
Where SaaS Custom Domains still wins
Honest flip side. If you want one vendor to serve HTTPS on customer domains with a WAF, DDoS protection and a global edge — or to run that stack inside your own infrastructure — SaaS Custom Domains does that and DoDomain never will (per saascustomdomains.com, retrieved 2026-09-02). A flat $29 for 100 domains is also a simpler line item than a connection allowance for a product whose customers are technical enough to add a record themselves.
Where DoDomain earns its place is the step every proxy leaves to the customer: writing the record through their provider where it can, guiding it precisely where it cannot, proving it at the source, and monitoring it for free — with no proxy in your request path and no bandwidth on the invoice.
Frequently asked questions
What does SaaS Custom Domains cost?
As published on saascustomdomains.com (retrieved 2026-09-02): a single plan at $29/month for 100 domains — $0.29 per domain — with automatic volume discounts of up to 50% as you scale toward 15,000+ domains, and a free trial that needs no credit card. Check saascustomdomains.com for current figures.
Is DoDomain an alternative to SaaS Custom Domains?
For serving traffic, no: SaaS Custom Domains is a proxy platform — automatic SSL, a WAF, DDoS protection, rate limiting and a 119-location edge in front of your app (per saascustomdomains.com); DoDomain never proxies and never issues certificates. For the DNS step, yes: DoDomain gets the record created inside the customer's own DNS provider — one-click on Cloudflare, a signed Domain Connect apply where the provider supports it, guided records with a live status everywhere else — verifies it at the authoritative nameservers, and monitors it afterwards, for free on every plan.
SaaS Custom Domains says DNS is configured automatically — what does DoDomain add?
Their page says DNS records are configured automatically (per saascustomdomains.com, retrieved 2026-09-02); it does not say the record is written inside the customer's DNS provider, which is the step only the customer can authorise. DoDomain does exactly that step: a scoped Cloudflare OAuth grant, or a signed Domain Connect apply on providers that have enabled DoDomain's registry-merged templates, writes the record in the customer's zone; everywhere else the customer gets their provider's exact dashboard link, the values with the host-field quirks explained, and a live per-record check. Every path ends with a read of the authoritative nameservers before your server is told.
How does DoDomain's free tier compare to the trial?
DoDomain's Free plan is $0 forever forever, with 50 verified connections per month, every connect tier, signed webhooks and drift monitoring, no card. SaaS Custom Domains offers a free trial with no card and then a $29/month plan for 100 domains (per saascustomdomains.com, retrieved 2026-09-02). They meter different things — connections made vs domains served.
Both mention monitoring — how do they differ?
SaaS Custom Domains lists continuous monitoring and a 99.999% uptime guarantee for the traffic it serves (per saascustomdomains.com, retrieved 2026-09-02). DoDomain monitors the DNS: every verified connection is re-read at the authoritative nameservers every 10 minutes for its first day, hourly for a week, then every 6 hours; a suspected drift is confirmed on three consecutive checks before a signed connection.failed names the failing records, and connection.verified fires again on recovery. One watches the edge; the other watches the record the customer controls.
Can I use DoDomain in front of SaaS Custom Domains?
Yes — the same pairing as with Cloudflare for SaaS or Approximated. Take the record value SaaS Custom Domains tells your customer to create, pass it to POST /api/v1/sessions, hand your customer the connectUrl or the @dodomain/connect widget, and activate the tenant when the signed connection.verified webhook arrives. This also works with their self-hosted deployment: DoDomain only needs the record value, never access to your edge.
