How to Connect SeaText to a Squarespace Development Domain
Create a dedicated SeaText account for your development domain, then paste the JavaScript snippet into the Header field of Squarespace's Code Injection panel under Developer Tools. Visit the site for at least 40 seconds...
To connect SeaText to a Squarespace development domain, you need a separate SeaText account for that domain and a valid, publicly accessible URL — localhost and dynamic subdomains are not supported. Once you have the account, copy the JavaScript snippet from the SeaText dashboard, open your Squarespace site settings, go to Developer Tools → Code Injection, paste the code into the Header area, save, and publish the site. Then visit the development site several times, staying on a page for at least 40 seconds, and wait up to ten minutes for the domain name to appear next to the SeaText logo in your account.
Why connecting a development domain matters
A development domain lets you test SeaText AI agents before they touch live traffic. You can verify translations, personalization rules, and CRO variants in a safe environment. This prevents accidental changes on your production site. Each domain you connect becomes a distinct property in SeaText, so data stays isolated. Testing on a real domain also confirms that the script loads correctly under actual network conditions.
Prerequisites before you start
You must have a SeaText AI account before you can install the script. If you do not have one, create it at the SeaText signup page. Each SeaText account is linked to a single primary URL, so a development domain requires its own account — you cannot reuse the production account. The development domain must be a real, publicly reachable domain; localhost, 127.0.0.1, and dynamic preview subdomains that change on each deploy are restricted for security reasons and will not reliably associate traffic with your account. You also need admin access to the Squarespace site so you can open Developer Tools and publish changes.
Step-by-step connection process
- Log in to your SeaText account for the development domain and copy the JavaScript integration snippet shown in the dashboard.
- Open your Squarespace dashboard, click the three-dot menu on the site thumbnail, and choose Settings.
- Scroll to the bottom of the settings page and open Developer Tools.
- Click Code Injection.
- Paste the SeaText JavaScript snippet into the Header field.
- Click Save.
- Publish the Squarespace site so the injected code is live on the development domain.
Each step must be completed in order. Skipping the publish step leaves the script inactive. The Header field ensures the script loads before page content, which is required for SeaText to rewrite text in real time.
Development domain considerations
SeaText treats every domain as a separate property. If you run a staging site at staging.example.com and a production site at example.com, you need two SeaText accounts. Dynamic development domains — such as Netlify or Vercel preview URLs that change on every push — may not function properly because SeaText cannot reliably associate the shifting hostname with a single account. Use a stable subdomain or a fixed staging domain instead. Password-protected sites, IP-restricted environments, and local development servers will not connect because SeaText cannot verify them.
Verification and activation
After publishing, visit the development site several times. Stay on any page for at least 40 seconds; this activity activates the AI and links the domain to your SeaText account. In the SeaText dashboard, watch the top of the page next to the SeaText logo. Your development domain name should appear within five minutes. If it does not appear after ten minutes, contact SeaText support — this usually indicates an installation issue on the platform side. The 40-second visit triggers the initial handshake between the script and the SeaText servers.
Common mistakes to avoid
- Pasting the snippet into the Footer field instead of the Header field.
- Forgetting to publish the Squarespace site after saving the Code Injection change.
- Using a localhost or dynamic preview URL that SeaText explicitly restricts.
- Reusing a production SeaText account for the development domain.
- Not waiting long enough for the connection to register; give it the full ten minutes before opening a support ticket.
Key facts
| Item | Details |
|---|---|
| Account model | One SeaText account per primary domain |
| Supported domains | Publicly accessible, stable domains only |
| Restricted URLs | localhost, 127.0.0.1, dynamic preview subdomains |
| Installation location | Squarespace → Settings → Developer Tools → Code Injection → Header |
| Activation trigger | Visit site, stay ≥ 40 seconds |
| Connection confirmation | Domain name appears next to SeaText logo within 5–10 minutes |
| Support escalation | Contact support if not connected after 10 minutes |
What happens after the domain connects
Once the domain name appears next to the SeaText logo, go to the Main AI Hub in your SeaText dashboard to activate the AI agents you want — translation, CRO, personalization, etc. — and configure their parameters. The AI remains inert until you enable specific agents. You can test translations on the development domain, run A/B copy tests, or preview personalization rules without affecting production data. Each agent has its own settings panel where you define target languages, test variants, or visitor segments.
Limitations and constraints
The connection process only works for domains that SeaText can reach and verify. Password-protected staging sites, IP-restricted environments, and local development servers will not connect. Each additional development or staging domain requires a separate SeaText account and a separate Squarespace Code Injection setup. The AI remains inert until the 40-second visit activation occurs, so no content changes or translations will appear before that step. If your development domain uses a CDN or edge caching layer, ensure the injected script is not cached in a way that prevents updates.
Troubleshooting checklist
- Confirm the script is in the Header field, not Footer.
- Confirm the site is published, not just saved.
- Visit the live development URL in an incognito window to bypass local cache.
- Stay on the page for a full 40 seconds; use a timer if needed.
- Wait ten minutes before checking the SeaText dashboard.
- If still not connected, open the browser developer console and look for SeaText script errors.
- Contact SeaText support with the development domain URL and a screenshot of the Code Injection panel.
Frequently asked questions
Can I use the same SeaText account for staging and production?
No. Each SeaText account is linked to a single primary URL. You must create a separate account for each domain, including development and staging domains.
What if my staging domain is a dynamic preview URL that changes on every deploy?
Dynamic development domains may not function properly because SeaText cannot reliably associate traffic with your account. Use a stable subdomain (e.g., staging.yourdomain.com) instead.
Why does the SeaText logo not show my domain name after installation?
Wait up to ten minutes. If the domain name still does not appear, verify that the snippet is in the Header field, the site is published, and you have visited the site for at least 40 seconds. Then contact SeaText support.
Does the script affect my live site while I am testing on the development domain?
No. The script only runs on the domain where it is installed. A development domain installation has no effect on your production site.
Can I install SeaText on a password-protected Squarespace trial site?
SeaText requires a publicly accessible domain. Password protection or trial-site restrictions that block anonymous access will prevent the connection from verifying.
What happens after the domain connects?
Once the domain name appears next to the SeaText logo, go to the Main AI Hub in your SeaText dashboard to activate the AI agents you want (translation, CRO, personalization, etc.) and configure their parameters.
How many development domains can I connect?
You can connect as many as you need, but each requires its own SeaText account and its own Squarespace Code Injection setup. There is no platform limit, but each account is billed separately.
Can I move a connected development domain to production later?
You would create a new SeaText account for the production domain and repeat the installation steps. Settings and test data do not transfer automatically between accounts.
