Custom subdomain — school.yourdomain.com
From its Q1 2027 launch, use a subdomain on your own domain from the Starter plan (e.g. school.yourdomain.com) pointing via CNAME to connect.slonto.com.
Soon — Q1 2027 Custom domains arrive in Q1 2027: this guide gets you ready for launch day.
What is a custom subdomain?
Your space is not on slonto.com/your_handle but on a subdomain of your own domain, e.g. school.yourdomain.com, academy.yourdomain.com or app.yourdomain.com. You keep ownership of your domain, Slonto just serves your space through that subdomain.
How to set it up in 2 steps
At your host / DNS (OVH, Cloudflare, Gandi, etc.)
Create a CNAME record: name = school (or academy), target = connect.slonto.com, TTL = Auto. Example: school.yourdomain.com CNAME connect.slonto.com.
In Slonto (Settings → Domain)
Enter your full subdomain (school.yourdomain.com) and validate. Slonto automatically provisions the SSL certificate (Let’s Encrypt) and checks DNS. Delay: 5 min to 2 h depending on propagation.
school.votredomaine.com CNAME connect.slonto.com
school.yourdomain.com CNAME connect.slonto.com
Verification & delays
Use dig school.yourdomain.com CNAME or https://dnschecker.org to see propagation. While the CNAME is not visible, Slonto shows “Awaiting validation”. Once validated, SSL is active and your space is reachable over https.
Limits & best practices
- 1 custom subdomain per space from the Starter plan (fair use).
- The subdomain must be a real subdomain (school.yourdomain.com), not a root domain (yourdomain.com) nor a path (yourdomain.com/school).
- You keep control of your DNS: delete the CNAME to cut the link at any time.
Frequently asked questions
Which CNAME target should I enter? +
Always connect.slonto.com, regardless of your host. Do not point to an IP.
How long does it take to work? +
The CNAME propagates in a few minutes to 2 hours. The SSL certificate is issued right after, automatically.
Can I use the root domain? +
No — use a subdomain (school.yourdomain.com). The root domain requires an ANAME/ALIAS record not supported in V1.
