Caches

A cache cluster is a managed Redis or Valkey deployment on your Hetzner account, with DNS endpoints, replicas, security groups, parameter groups, and backups.

How it works

1. Create a cache and wait until Status is Ready.
2. Open TCP port 6379 on the attached security group for your client CIDR.
3. Connect with the read/write domain and the password you set at create time.
4. (Optional) Add replicas, promote a replica, or configure backups.

Engines

Endpoints

• Read/write domain — current primary
• Read-only domain — replicas when present

In the console

Choose Cache in the navigation pane. From there you can list clusters, manage parameter groups, backup policies, and backup runs. Pricing is per engine instance type — see the cache pricing page.
