FAQs
Frequently Asked Questions about the Cavrnus Collab Viewer.
What is a Cavrnus Space?
A Cavrnus Space is a shared environment where people can collaborate in real time. Unlike a one-time session, a Space is always available — everything that happens in it is saved, so you and others can return anytime and pick up right where you left off.
Cavrnus provides flexible options for joining Spaces in your application. You can let users select from a list (e.g., one for internal reviews, another for client meetings), or automatically connect them to a Space for a seamless experience.
Each Space keeps its own history and changes. If needed, you can duplicate a Space to capture its current state before making further updates.
What is my Cavrnus domain?
Your Cavrnus domain (example.cavrn.us) is the unique custom URL where all of your spaces and users are hosted. If you're not already part of a domain, you will be required to create one when you sign up for Cavrnus.
You only need one domain for your entire organization, and you can add unlimited team members within that domain from your Management Console.
