Features/Custom Domains

Custom Domains

Agent deploys to your domain. Automatic SSL. No config.

Updated March 2026

Every plan gets a custom subdomain — alice.sutrena.com. Pro and above can add your own domain — mysite.com. Point a CNAME record, SSL is automatic, pages are served from your domain. No DNS wizardry required. Agent creates, humans visit your domain.

What it does

✓Custom subdomains on all plans — alice.sutrena.com (free)
✓Custom domains on Pro+ — mysite.com, docs.yourcompany.com
✓Automatic SSL via Cloudflare — no certificate management
✓CNAME setup — point your domain to cname.sutrena.com
✓DNS and SSL status tracking — pending, verified, active
✓Slug-based routing — mysite.com/about serves the page with slug 'about'
✓Root path — mysite.com/ serves the page with slug 'index'
✓Domain verification via API — check status anytime
✓Instant environment switching — re-point a domain from staging to production subdomain with one API call, no DNS changes
✓Limits: Pro 5 domains, Scale unlimited

How it works

# 1. Set your subdomain (all plans)
curl -X PUT https://sutrena.com/api/account/subdomain \
  -H "Authorization: Bearer YOUR_KEY" \
  -H "Content-Type: application/json" \
  -d '{"subdomain": "alice"}'

# Pages now served at alice.sutrena.com/slug

# 2. Add a custom domain (Pro+)
curl -X POST https://sutrena.com/api/account/domains \
  -H "Authorization: Bearer YOUR_KEY" \
  -H "Content-Type: application/json" \
  -d '{"domain": "mysite.com"}'

# Returns CNAME instructions. Add the DNS record. SSL is automatic.

Set a subdomain for free. Add custom domains on Pro+. Point a CNAME, SSL happens automatically.

What it does not do

Custom domains require DNS changes on your registrar. If you do not know what a CNAME record is, your hosting provider or domain registrar has guides for it. We cannot manage your DNS for you. Also, free plan does not get custom domains — subdomains only.

FAQ

How long does SSL take to set up?

Usually a few minutes after the CNAME record propagates. DNS propagation itself can take up to 48 hours depending on your registrar, though most are faster. Sutrena checks periodically and activates SSL automatically.

Can I use a subdomain of my own domain?

Yes. docs.yourcompany.com, blog.yourcompany.com — any subdomain works. Each is added as a separate custom domain linked to its own Sutrena subdomain. Add a CNAME record for each pointing to cname.sutrena.com. Each counts toward your plan's domain limit. See the [full guide](/answers/can-i-use-subdomains-of-custom-domain).

What is the difference between subdomains and custom domains?

Subdomains are alice.sutrena.com — free on all plans. Custom domains are mysite.com — your own domain, requires Pro plan ($29/mo) or higher. Both serve the same pages.

How many custom domains can I add?

Pro ($29/mo): 5. Scale ($99/mo): unlimited. Subdomains (alice.sutrena.com) are available on all plans: Free gets 1, Pro and Scale unlimited.
