Custom Domains

Serve your thig.ai workspace from a custom domain like prd.yourcompany.com. Custom domains are available on Business and Enterprise plans.
Custom domains require the Business or Enterprise plan. If you’re on a lower plan, you’ll see an upgrade prompt on the domain settings page.

​
Setup

​
Step 1: Choose Your Domain

  1. Go to Settings > Custom Domain (/admin/settings/domain)
  2. Enter your desired domain (e.g., prd.yourcompany.com)
  3. Click Configure Domain
thig.ai generates a unique verification token and shows you the DNS records to add.

​
Step 2: Add DNS Records

You need to add two DNS records at your domain registrar (e.g., Cloudflare, Namecheap, Route 53, GoDaddy):

​
CNAME Record

FieldValue
TypeCNAME
Name/HostYour subdomain (e.g., prd for prd.yourcompany.com)
Target/ValueThe CNAME target shown on the settings page
TTL300 (or “Auto”)
This routes traffic from your domain to the thig.ai servers.

​
TXT Record

FieldValue
TypeTXT
Name/Host_verification.yourdomain.com
ValueThe verification token shown (starts with airprd-verify-)
TTL300 (or “Auto”)
This proves you own the domain.
Copy the DNS record values exactly as shown on the settings page. Extra spaces or missing characters will cause verification to fail.

​
Step 3: Wait for DNS Propagation

DNS changes typically take 5–30 minutes to propagate, but can take up to 48 hours in rare cases. You can check propagation status using tools like dnschecker.org.

​
Step 4: Verify

  1. Return to Settings > Custom Domain
  2. Click Verify Domain
  3. thig.ai checks both your CNAME and TXT records in real-time
  4. If both pass, your domain is marked as verified and active

​
Step 5: SSL Certificate

SSL is provisioned automatically by the hosting infrastructure after verification. Your custom domain will be accessible via https:// immediately — no manual certificate setup required.

​
Verification Details

The verification process checks two things:
CheckWhat It Validates
CNAMEYour domain points to the correct thig.ai server
TXTThe _verification record contains your unique token
Both checks must pass for the domain to be verified. If either fails, the settings page shows which record is missing or incorrect.

​
Verification Rate Limiting

Domain verification requests are rate-limited to prevent abuse. If you see a rate limit error, wait a minute and try again.

​
After Verification

Once verified:
  • Your workspace is accessible at https://yourdomain.com
  • The original app.thig.ai URL continues to work
  • All API endpoints work on both domains
  • SSL is active with automatic certificate renewal

​
Managing Your Domain

​
Changing the Domain

  1. Go to Settings > Custom Domain
  2. Click Edit
  3. Enter the new domain
  4. You’ll need to repeat the DNS setup and verification for the new domain
Changing your domain requires re-verification. The old domain stops working immediately.

​
Removing the Domain

  1. Go to Settings > Custom Domain
  2. Click Remove Domain
  3. Your workspace reverts to app.thig.ai

​
Domain History

The settings page shows a log of all domain changes:
  • When the domain was added
  • Verification attempts (successful and failed)
  • When the domain was removed or changed
  • Who performed each action

​
Troubleshooting

IssueSolution
CNAME not foundCheck that you added the CNAME record at your registrar. DNS may still be propagating — wait 15–30 minutes and try again.
CNAME points to wrong valueUpdate the CNAME target to match the value shown in thig.ai settings.
TXT not foundEnsure the TXT record name is _verification.yourdomain.com (with the underscore prefix).
TXT value doesn’t matchCopy the verification token exactly from the settings page. Some registrars add quotes — remove them if present.
Verification fails after waitingUse dnschecker.org to confirm your records are visible globally. Some registrars have a delay before records go live.
SSL not workingSSL is provisioned automatically. If it takes more than a few minutes, verify the CNAME is correct — SSL depends on the domain routing correctly.
Domain already takenEach domain can only be connected to one organization. If you previously used this domain, remove it from the old organization first.
”Business plan required”Custom domains require a Business or Enterprise plan. Upgrade from Settings > Billing.

DNS Provider Examples

  1. Go to your domain’s DNS settings in Cloudflare
  2. Click Add Record
  3. For CNAME: Type = CNAME, Name = your subdomain, Target = the CNAME target from thig.ai, Proxy status = DNS only (gray cloud)
  4. For TXT: Type = TXT, Name = _verification.yourdomain.com, Content = your verification token
  5. Click Save
Important: Set the CNAME proxy status to “DNS only” (gray cloud icon), not “Proxied” (orange cloud). Cloudflare’s proxy can interfere with SSL provisioning.
  1. Go to Domain List > your domain > Advanced DNS
  2. Click Add New Record
  3. For CNAME: Type = CNAME, Host = your subdomain, Value = the CNAME target, TTL = Automatic
  4. For TXT: Type = TXT, Host = _verification, Value = your verification token, TTL = Automatic
  5. Click the checkmark to save
  1. Go to Hosted zones > your domain
  2. Click Create record
  3. For CNAME: Record name = your subdomain, Record type = CNAME, Value = the CNAME target, TTL = 300
  4. For TXT: Record name = _verification.yourdomain.com, Record type = TXT, Value = "your-verification-token" (wrapped in quotes), TTL = 300
  5. Click Create records
  1. Go to My Products > your domain > DNS
  2. Click Add under Records
  3. For CNAME: Type = CNAME, Name = your subdomain, Value = the CNAME target, TTL = 1/2 Hour
  4. For TXT: Type = TXT, Name = _verification, Value = your verification token, TTL = 1/2 Hour
  5. Click Save
