The short answer

Connect a custom domain to a Replit Deployment from the Publishing tool's Domains tab: click 'Link a domain' and enter your domain. Replit either configures DNS automatically (supported registrars) or shows an A record and a TXT verification record to add manually. Replit then issues and auto-renews the SSL certificate via DNS validation.

How connecting a domain to Replit works

Replit uses an A record + TXT pair (not a CNAME), and both values are generated per-domain and shown in your Domains tab — Replit does not publish a fixed A-record IP, so copy the exact IP and TXT value from your own dashboard rather than reusing one from a blog.

The TXT record (replit-verify=…) must stay in DNS permanently — removing it after setup breaks the next certificate renewal. Linking the apex does NOT serve www; add www as a separate linked domain with its own records. SSL is issued and renewed by Replit automatically.

Step by step

  1. Have or buy the domain (search and register on JustDomain.ai).
  2. Open your Deployment → Publishing tool → Domains tab.
  3. Click 'Link a domain' and enter your domain name.
  4. Either authorize Replit to configure DNS automatically, or copy the shown A and TXT records for manual setup.
  5. At your registrar, paste the A record and the replit-verify=… TXT record exactly as shown.
  6. To also serve www, link www.yourdomain.com separately with its own records. Wait for propagation; Replit shows 'Verified' and issues HTTPS.

Common gotchas

  • Never delete the replit-verify TXT record — it's needed for ongoing cert renewal, not just setup.
  • Linking the apex does not cover www — add www as its own linked domain.
  • Don't reuse an A-record IP from a tutorial — the IP and TXT are generated for your specific domain.
  • Common failures: a trailing dot, an extra/stale record, or a subdomain typo. Copy values verbatim.
