Custom domains let you assign your own domain name, such as www.my-incredible-app.com, to your Replit published app. While Replit provides a free subdomain in the format <your-live-app-subdomain-name>.replit.app, a custom domain gives your app a more memorable address that builds brand recognition and trust with your visitors. The Domains tab in the Publishing tool gives you everything you need in one place. You can:
  • Buy a new domain through Replit and connect it to your project in one step.
  • Connect a domain you already own from another registrar.
  • Manage your connected domains — view which project each one points to, track renewals, and disconnect a domain.
Watch the following video for a quick overview of setting up custom domains:

​
Buy a new domain on Replit

If you don’t already own a domain, you can search for one and buy it without leaving Replit. Your new domain points to your project automatically.
1

Open the Domains tab

Open the Publishing tool and select the Domains tab.
2

Search for a domain

Select Buy a new domain and enter the name you want. Replit shows available options across extensions such as .com, .ai, and more. If you’re not sure what to call it, Replit also suggests available names based on what your app does, so you can pick one without starting from scratch.

Purchase and connect

Select your preferred domain and complete the purchase using your Replit account’s payment method. Your app becomes accessible at the new domain right away, with no additional DNS configuration.
Domains bought through Replit include WHOIS privacy protection at no extra cost, renew automatically, and let you add custom DNS records (for example, MX records for email). For the full reference on buying domains — pricing, renewals, transfers, and custom DNS records — see Purchase a domain.

​
Connect a domain you already own

If you already own a domain at another registrar, connect it to your project from the Domains tab. Replit offers a guided setup that configures your DNS for you, with a manual option as a fallback. The simplest way to connect an existing domain is to let Replit set it up for you. Replit uses Entri, a third-party domain-connection service: after you authorize it, Entri signs in to your DNS provider and writes the required DNS records on your behalf, so you don’t have to copy them by hand.
DNS records are the settings that tell the internet where your domain should point. Setting them up by hand used to be the trickiest part of connecting a domain. Replit now handles this step for you for most domains and providers.
1

Open the Domains tab

Open the Publishing tool and select the Domains tab.

2

Enter the domain you want to connect

Select Connect your own domain and enter a domain you already own, such as www.my-incredible-app.com.
3

Authorize the guided setup

Confirm the connection. Replit opens the guided flow, where you sign in to your DNS provider so the DNS records can be applied to your account automatically. If the guided flow can’t write the records for your provider, it shows you the records to add yourself instead.
4

Wait for your domain to verify

Your domain shows a Verified status once setup completes. This usually takes a few minutes, but DNS changes can take up to 48 hours to propagate. Load the domain in your browser to confirm it works.
If your provider isn’t supported for guided setup, or you prefer to add the records yourself, you can connect your domain manually. See Connect a domain manually below.

​
Connect a domain manually

If your provider isn’t supported for guided setup, or you prefer to add the records yourself, follow the steps below to set up your custom domain manually.
You might experience setup issues if you have one of the following:
  • Multiple A records for the same domain name that point to different servers.
  • A and AAAA records co-exist for the same domain, since Replit only supports A records.
  • Cloudflare proxied domain records, since Replit cannot automatically renew security certificates for that type. Set your record to DNS only (the gray cloud).
  • A missing or removed replit-verify TXT record. Replit needs this record to remain in place to renew your SSL/TLS certificate. See Keep the TXT record in place below.
1

Add your custom domain

Enter your custom domain name in the text field. You can use a registered domain or include a subdomain.For example, hat-tip.cc is the registered domain and my.hat-tip.cc includes subdomain my.

Add the DNS records to your domain registrar

Replit generates DNS records that you must provide to your domain registrar. A domain registrar is the service that manages your domain name, such as GoDaddy or Namecheap.Copy the A and TXT record values from Replit and paste them into your domain registrar’s DNS management section. If your domain registrar does not support @ as a hostname, use your registered domain name.
Keep the TXT record in place. Replit issues and renews the SSL/TLS certificate for your custom domain through DNS validation. The replit-verify=... TXT record must stay in your DNS for the full lifetime of the domain — not only during initial setup. If you remove or change the record after verification, your next certificate renewal will fail and your domain will eventually serve an expired certificate, making your app unreachable in browsers. Treat the TXT record as permanent alongside your A record.

Optional: Add a subdomain

Subdomains — including www — are not automatically resolvable when you link your apex domain. Each subdomain you want to serve must be added as its own entry in the Domains tab and given its own DNS records at your registrar.To add a subdomain, link it from the Domains tab the same way you linked the apex domain, then add the DNS records Replit generates for it to your domain registrar. For example, to add my-subdomain.hat-tip.cc:
  • In the Publishing tool, select the Domains tab and link my-subdomain.hat-tip.cc.
  • At your registrar, add a new A record with hostname my-subdomain pointing to the IP address Replit shows for the new entry.
  • At your registrar, add the matching replit-verify=... TXT record on hostname my-subdomain — each subdomain has its own TXT record, separate from the apex’s.
www is a subdomain. Linking hat-tip.cc does not automatically serve www.hat-tip.cc. If you want visitors to reach your app at both hat-tip.cc and www.hat-tip.cc, add www.hat-tip.cc as a separate entry in the Domains tab and publish the A and TXT records it generates on hostname www. Most builders who want a www address also configure a redirect from the apex to www (or vice versa) at their registrar.
As with the apex domain, the replit-verify=... TXT record you add for each subdomain must stay in DNS permanently. See Keep the TXT record in place below.

Wait for DNS propagation to complete

After adding the records, you must wait for them to propagate online. This can take between a few minutes and 48 hours.When the propagation completes, your Domains tab should show the “Verified” status next to the domain name as shown below:

Load the domain in your browser to verify that it works.

​
Manage your domains

The Domains tab lists every domain connected to your project and lets you manage each one. Select a domain and choose Manage to:
  • See which project the domain points to. If you try to connect a domain that’s already linked to another of your projects, Replit warns you and lets you move it to the current project instead.
  • Review renewals (for domains bought on Replit). The management view shows the renewal date and renewal price, and lets you turn Auto renewal off if you don’t want the domain to renew automatically.
  • Edit DNS records (for domains bought on Replit). Add custom A, TXT, or MX records — for example, MX records to use your domain for email. See Custom DNS records.
  • Disconnect the domain. Disconnecting stops serving your app at that domain. The domain itself isn’t deleted — it stays available to link to another of your projects.

Troubleshooting

If a connection fails or the domain stays on Verifying, work through these checks:
  1. Give DNS time to propagate. Verification can take from a few minutes up to 48 hours. Use a DNS lookup tool to confirm your records are visible globally before changing anything else.
  2. Remove conflicting records. Keep only one A record at your root domain pointing to Replit, and remove any AAAA (IPv6) records on the same hostname — they can block SSL.
  3. Turn off Cloudflare proxying. Set your A record to DNS only (the grey cloud). Proxy mode (the orange cloud) interferes with SSL provisioning.
  4. Confirm the TXT record is present. A missing or modified replit-verify=... TXT record blocks verification and certificate renewal. See Keep the TXT record in place.
  5. Disconnect and reconnect the domain from the Domains tab to force a fresh certificate, then wait a few minutes and reload.
If you bought your domain through Replit and it still won’t verify, contact Replit Support.

​
DNS changes haven’t taken effect yet

DNS changes are not instant. After you add or change records, expect to wait anywhere from a few minutes to 48 hours for them to propagate worldwide. Your app keeps working on its replit.app subdomain during this time. If the Verified status hasn’t appeared after 48 hours, recheck your records against what Replit shows — common mistakes are a trailing dot, an extra subdomain, or a stale record.

​
CNAME records and authentication

You don’t need a CNAME record for sign-in or authentication to work on your custom domain. Sign-in works across your published domain automatically once the domain is verified. CNAME records on a custom domain are only required for email sending — for example, so that verification or transactional emails can be sent from your domain. If the Publishing tool shows a warning asking you to add CNAME records, that’s about email delivery, not login. Adding the records is only necessary if you send email from your domain; it does not block your domain’s verification, SSL, or sign-in. For the email-related setup steps, see Clerk authentication.

​
Keep the TXT record in place

Replit issues and renews the SSL/TLS certificate for each custom domain through DNS validation, which depends on the replit-verify=... TXT record you added during setup. The TXT record is not a one-time setup artifact — it must stay in your DNS for the full lifetime of the domain. If the record is removed, edited, or replaced after your domain is verified, the next renewal will fail silently and the existing certificate will eventually expire. Visitors will then see a browser security warning and the app will be unreachable. If older domains on your account suddenly show certificate errors while newer ones work, a missing or modified TXT record is the most likely cause. To restore an affected domain:
  1. Open the Publishing tool and select the Domains tab.
  2. Confirm the replit-verify=... TXT record Replit shows for the domain.
  3. Add the TXT record back at your domain registrar exactly as shown, including the hostname and value.
  4. Remove the domain in Replit and add it again to trigger a fresh issuance.
  5. Wait for DNS propagation and re-check the Verified status on the Domains tab.
