As an alternative to hosting your own Trilium instance, there are two services out there that provide out of the box support for Trilium.

Cloud instance providers

PikaPods

1. Go to pikapods.com  and sign up.
2. In the “Available Apps” section, look for "TriliumNext
    and select “Run your own”.
3. Follow the on-screen instructions to set up your own cloud hosted instance.

PikaPods generally updates their Trilium instances to the latest version within a two-week interval after a new version is released.

trilium.cc

Trilium.cc is a cloud service dedicated to hosting a Trilium instance.

Matching your version with the cloud instance

Please note that once you set up Synchronization between a cloud instance and desktop clients, it's important that the version of the desktop application and the server match up.

When setting up a cloud instance, it's best to check the version of the server by accessing it via a web browser and going to the About section. It's best that both the desktop and the server have the same App version; however it's generally OK to update the desktop to a newer version than the server if it has the same Sync version.

If the Sync version between the server and the desktop application doesn't match, synchronization will not work.
