Adding Domains

Overview

Adding a domain to RndrKit tells the service which custom domain you want to pre-render and where the original application is hosted. Each domain you add creates a mapping between your public-facing URL and your origin server.

Before You Begin

Make sure you have the following information ready:

• Your domain: The domain your visitors use (e.g., example.com). Enter just the domain name — no https:// and no www. prefix. RndrKit treats the apex as canonical and automatically handles the www subdomain.
• Origin URL: The full URL where your application is actually hosted (e.g., https://your-app.lovable.app, https://my-app.vercel.app, or any other hosting provider)

Adding a Domain

1. Log in to your RndrKit dashboard at rndrkit.io.
2. Open the Domains page and click the Add Domain button.
3. Fill in the domain details:

4. Click Continue to DNS Setup. RndrKit will advance to a two-step wizard (Domain → DNS Setup) and show the exact DNS records you need to add.

Domain Status

Each domain card on the Domains page shows one of two top-level states:

• Active -- The domain is enabled and serving pre-rendered content to bots.
• Inactive -- The domain has been manually deactivated from its Settings tab.

The domain's Settings tab also shows a separate SSL status, which can be:

• Active -- SSL certificate is issued and in use.
• Pending Validation -- DNS has been accepted but the certificate is still being validated.
• Pending -- SSL provisioning is queued or in progress.
• Failed -- SSL provisioning failed. Re-check your DNS records and try again.

Apex and www Domains

RndrKit serves your site on both the apex (e.g., example.com) and the www subdomain (e.g., www.example.com). Because you enter the apex when adding a domain, the DNS Setup step gives you two records to add for apex domains:

• An A record for @ pointing to 35.153.65.36 (covers the apex).
• A CNAME record for www pointing to the value shown in the dashboard (covers www.example.com).

SSL is provisioned automatically for both records once DNS propagates. Add both records so visitors reach your site whether they type the apex or the www form.

If your DNS provider supports apex CNAME / ALIAS records (for example Cloudflare, Route 53, DNSimple, Netlify DNS, or Vercel DNS), you can use an ALIAS-style record at the apex instead of the A record. Most registrar-provided DNS (GoDaddy, Namecheap, Google Domains, Hostinger) does not support this — use the A record shown in the dashboard.

For subdomain-only setups (e.g., app.example.com), the dashboard shows a single CNAME record pointing the subdomain to the provided target.

Origin URL Format

The origin URL should be the full base URL of your hosted application, including the protocol:

Correct:   https://example.lovable.app
Correct:   https://my-app.vercel.app
Incorrect: example.lovable.app
Incorrect: example.lovable.app/

RndrKit will proxy human traffic to this origin URL.

Multiple Domains

You can add multiple domains to your RndrKit account. Each domain is tracked independently with its own:

• Render count and usage limits
• Cache entries
• Analytics data
• SEO tool configurations

Your plan determines how many domains you can add. See Plans and Pricing for details.

After Adding a Domain

Once your domain is added, you need to:

1. Configure DNS -- Point your domain to RndrKit's servers. See DNS Configuration.
2. Verify SSL -- Confirm that the SSL certificate has been provisioned. See SSL Verification.
3. Test rendering -- Verify that bot requests receive pre-rendered HTML.

# Test that bot rendering is working
curl -s -A "Googlebot/2.1" "https://www.example.com/" | head -50

Removing a Domain

To remove a domain from RndrKit:

1. Go to the Domains page in the dashboard.
2. On the card for the domain you want to remove, click the trash (delete) icon.
3. Confirm the deletion in the Delete Domain dialog.

After removing a domain, remember to update your DNS records to point back to your original hosting provider.
