CustomDomain™ vs Entri: an honest comparison

If you are researching how to let your customers connect their own domains to your product, you have almost certainly found Entri. It deserves the attention. Entri is an established name in this category, its connection modal is polished, and its pricing page carries testimonials from ClickFunnels and Fourthwall. Any comparison page that tells you the other product is terrible is not worth your time, so let us say it plainly: Entri is a solid product built by a team that knows domains.

We built CustomDomain™ because we think the job deserves a different shape: one product that covers the entire path from "customer types a domain" to "HTTPS traffic is being served". Pricing starts at $10 a month, after a 14 day free trial, for the connect widget, DNS engine, and API, so you can wire it in before custom domains are a revenue line, and the reverse-proxy edge with automatic HTTPS arrives on the Growth plan. This page lays out where the two products overlap, where they differ, and how to decide. What this page says about Entri comes from its pricing page and developer docs as of October 2026, and you should check their site for current pricing.

What Entri does well

Entri Activate, included in every plan, bundles three products. Connect is the flagship: an embeddable modal that detects where a domain's DNS is managed, walks the user through authorizing access, and applies the required records automatically, and Entri advertises support for 70+ DNS providers. Sell lets users buy a domain inside the modal through a registrar partner such as IONOS, Squarespace, or GoDaddy, with 500+ domain extensions and a flat commission per sale. Monitor watches the DNS records after setup and sends a webhook when one is changed or deleted. Power and Secure are add-ons to any plan: Power hosts root domains through a reverse proxy with SSL termination, and Secure automates SSL provisioning. Entri does not show add-on prices on its pricing page.

Two things stand out. First, Connect is built around the hand-off problem: its shared links let a user forward the setup to a colleague who manages their DNS, which solves a real workflow problem when the person using your product is not the person with the DNS login. Second, Entri reports 5M+ connected domains on its homepage, a track record that counts if your procurement process weighs vendor history heavily.

What CustomDomain™ does differently

CustomDomain™ is one product, not a suite. The control plane manages connections, records, verification, and certificates. A reverse-proxy edge terminates TLS and serves traffic on your customers' domains with strict multi-tenant isolation. You do not assemble DNS configuration, certificate automation, and hosting from separate products, because the whole path ships together, with the reverse-proxy edge included from the Growth plan.

The differences that tend to matter in an evaluation:

• Provider coverage and fallback. CustomDomain™ supports 63 DNS and registrar providers through one-click provider authorization or an API token. When a provider is not covered, a guided manual flow shows the exact records and verifies them automatically, so no customer hits a dead end.
• Time to live. On the reverse-proxy edge, a connected domain is typically serving HTTPS in about 30 seconds: records written, ownership verified, certificate issued before the first request. See how TLS automation works.
• API surface. The REST API covers connections, DNS records, TLS status, monitoring, webhooks, and registrar search and purchase. Everything the widget does, the API does.
• AI agents. Both products ship an MCP server. Entri's server exposes Connect and Sell through six tools, and its connect and purchase tools return a sharing link that the user opens to finish the DNS setup or the checkout. The CustomDomain™ server has 17 tools and lets an agent search for, buy, connect, and verify a domain through the same gates a person gets. If agent-driven onboarding is on your roadmap, read connecting domains with AI agents.
• Pricing floor. CustomDomain™ starts at $10 a month after a 14 day free trial. Entri's published plans start at $249 per month.

Entri pricing vs CustomDomain™ pricing

As of October 2026, Entri publishes one price. The Startup plan is $249 per month, month to month, for 600 domain connections per year and 1,200 monitored domains, with webhooks and basic configuration options. Growth (2,400 connections per year), Premium (12,000), and Enterprise (more than 12,000, with advanced white labeling) are quoted through sales. Every plan includes Connect, Sell, and Monitor. The Secure and Power add-ons, for SSL and root domain hosting, show no price. No free tier or free trial is listed. Pricing changes, so check entri.com for current numbers.

CustomDomain™ starts at $10 a month after a 14 day free trial. Starter includes 10 domain connections a year with the connect widget, REST API, webhooks, DNS drift detection, and the MCP server. Startup is $149 a month for 600 connections a year, the same yearly allowance as Entri's Startup plan at $249. The reverse-proxy edge and automatic HTTPS arrive on Growth at $649 a month, and the tiers scale with domain connections per year, as published on our pricing page. The practical difference is the starting point. With Entri, custom domains start at $249 a month, nearly $3,000 a year if you keep the plan, before the first customer connects. With CustomDomain™, you can ship the feature this week, watch real customers use it, and pay when the volume is real.

When Entri is the right choice

An honest comparison names the cases where the other product wins.

• You want a track record at scale and recognizable references. Entri reports 5M+ connected domains and publishes customer testimonials. If procurement weighs that heavily, it is a fair reason to choose them.
• You want commission-based domain reselling with the registrar relationships fully handled. Entri Sell partners with registrars who take on support, billing, and compliance, and pays you a commission on sales. If reselling domains is a revenue strategy rather than a convenience, Sell is built for exactly that and comes with every Entri plan.
• You already run your own edge and only want the DNS modal at high volume. If you have invested in your own certificate and proxy infrastructure and are happy with it, an Entri plan without the Power and Secure add-ons, negotiated at your volume, may fit the org chart better than adopting an integrated platform.
• You need setup delegation features today. Connect's shared links, which let the end user forward the setup to the colleague who manages their DNS, are a thoughtful piece of the flow.

When CustomDomain™ is the right choice

• You want one integration, not an assembly. DNS configuration and ownership verification come on every plan, and from Growth the reverse-proxy edge adds TLS issuance and renewal and traffic serving, all in a single product with a single bill. Read the integration guide to see the whole flow.
• You are early, or custom domains are not yet proven revenue. A 14 day free trial, then $10 a month, means the feature can earn its keep before it costs much.
• You build API-first. Every capability, including registrar search and purchase, is a documented REST endpoint, not a modal you script around. The docs are public, no demo call required.
• AI agents are part of your product. Both vendors ship an MCP server. Ours covers search, purchase, connection, and verification, which matters for agent platforms and increasingly for everyone else.
• Your customers use long-tail providers. 63 providers plus an automatically verified manual flow means the connection rate does not fall off a cliff outside the top registrars.

Migrating from Entri to CustomDomain™

Migration is less dramatic than it sounds, because connected domains are just DNS records pointing at an edge.

1. Inventory your connected hostnames. Export the list of live customer domains and note which are apex domains and which are subdomains. (Unsure of the difference? See apex domain vs CNAME.)
2. Run both side by side. Point new signups at the CustomDomain™ widget while existing domains keep resolving through your current setup. Nothing breaks by adding us.
3. Move existing domains in batches. Create the connection on our side first, then update the customer's record to target our edge, which is part of the Growth plan. Certificates issue automatically when the domain arrives, so there is no manual TLS step and no certificate gap. The mechanics are covered in multi-tenant TLS.
4. Re-point your webhooks. Our webhook events cover connection status, record propagation, and certificate lifecycle, so status pages and onboarding emails keep working with a small payload mapping.

The swap can be completed in days, not weeks, and the 14 day free trial means you can validate the full flow before committing. If you want a second pair of eyes on your migration plan, book a short call and we will walk through it with you.

Frequently asked questions

What is Entri?

Entri is a domain setup service for software companies. Its Connect modal detects a user's DNS provider and applies the records for them, so a customer can point a domain at your product without editing DNS by hand. Sell lets users buy a domain through a registrar partner, Monitor sends a webhook when a monitored record is changed or deleted, and the Power and Secure add-ons handle root domain hosting and SSL. Entri advertises support for 70+ DNS providers, and plans start at $249 per month as of October 2026.

Is there a free Entri alternative?

Not a free tier, but a free trial. CustomDomain™ starts with a 14 day free trial, then Starter is $10 a month, and it includes the connect widget, the REST API, webhooks, DNS drift detection, and the MCP server. As of October 2026, Entri lists no free tier or trial, and its only published price is $249 per month for Startup. You can sign up and start the trial, then connect a domain without a sales call.

How much does Entri cost?

As of October 2026, Entri's published pricing is one plan: Startup at $249 per month, month to month, for 600 domain connections per year. Growth (2,400 connections per year), Premium (12,000), and Enterprise (more than 12,000) are quoted through sales. Every plan includes Connect, Sell, and Monitor, and the Secure and Power add-ons show no price. Check entri.com for current pricing.

Can I migrate from Entri without downtime?

Yes. Existing customer domains keep resolving through your current setup until each one is re-pointed, so you can migrate in batches at your own pace. CustomDomain™ issues certificates automatically when a domain arrives at our edge, so there is no gap in HTTPS during the move.

Does CustomDomain™ cover as many DNS providers as Entri?

Not by the headline count. CustomDomain™ supports 63 DNS and registrar providers through one-click provider authorization or API tokens, and Entri advertises 70+ DNS providers. For any provider outside our list, a guided manual flow shows the exact records and verifies them automatically, so every customer has a working path. The full flow is on the features page.

Does Entri have an MCP server?

Yes. Entri's MCP server, at mcp.entri.com, exposes Connect and Sell as six tools: searching domain availability, generating suggestions, creating a domain order, connecting a domain, and checking connection and order status. It uses OAuth 2.0 machine-to-machine authentication, and its connect and purchase tools return a sharing link that the user opens to finish the DNS setup or the checkout. The CustomDomain™ server has 17 tools and lets an agent search for, buy, connect, and verify a domain.
