Every app deployed on Nixopus gets HTTPS out of the box. Custom domains work with automatic SSL certificates — no configuration files, no manual renewal.
You can manage domains through the AI Chat or the editor extension — just ask the agent to add or configure a domain and it handles the rest.

​
Domain assignment

When creating or configuring an app, you add domains from the Configuration tab. Each app supports up to 5 domains.
Add domains directly — each domain routes to your app’s exposed port.

​
Automatic HTTPS

Nixopus provisions SSL certificates automatically for every domain:
  • Nixopus Cloud — certificates are issued at the edge via Let’s Encrypt. Zero configuration.
  • Self-hosted — Caddy handles certificate provisioning and renewal. As long as your machine is reachable on ports 80 and 443, HTTPS works automatically. See HTTPS configuration for details.

​
Nixopus Cloud subdomains

On Nixopus Cloud, every app gets a *.nixopus.ai subdomain by default. You can also add a custom domain on Pro, Team, or Enterprise plans.

​
Self-hosted domains

For self-hosted installations, point your domain’s DNS (A record) to your machine’s IP address. Nixopus detects the domain and configures the reverse proxy automatically. 
A   app.example.com   →   your-machine-ip
Ensure ports 80 and 443 are open on your machine’s firewall for SSL certificate issuance to work. See firewall configuration for setup instructions.
