Every project gets two URLs, and it’s worth knowing which is which.

​
The preview URL

While you build, your app is live at a unique preview subdomain (you can open it from the preview panel’s “open in new tab” button). It reflects the workspace in real time — including changes the agent is mid-way through — and it sleeps when you’re away. Treat it as yours to poke at, not as something to share with customers.

​
The production URL

Publishing gives your app a permanent production URL on its own subdomain (the shape is your-project.app.convonexai.tech), served over HTTPS with a valid certificate — nothing to configure. The production URL:
  • stays up independently of your preview and your workspace,
  • only changes content when you publish again,
  • is safe to put in front of real users.
An unclaimed or removed hostname returns a plain 404 — one project’s traffic can never fall through to another project’s app.

​
Custom domains

Serving your app from a domain you own (like app.yourcompany.com) is on the roadmap but not self-service yet — if it’s important for a launch, contact support. (Custom email sending domains are different, and already work — see Email.)
