Reading the field
Vaultwarden
The core loop is what Vaultwarden does best. Plan for 1 vCPU and 1 GB of RAM. Its install count is not luck — it is the default answer for most security questions we see.
Bitwarden
Bitwarden covers the essentials without demanding a manual. Plan for 2 vCPU and 4 GB of RAM. Worth a demo before you commit to the leader.
Keycloak
The core loop is what Keycloak does best. It runs comfortably on 2 vCPU / 4 GB here. Newer to the catalog, climbing steadily.
Authelia
Teams pick Authelia when they need the basics done well. It runs comfortably on 1 vCPU / 2 GB here. A niche pick that earns its place.
Choosing a server
None of these need a big machine. Budget roughly €0.046/hour for the largest spec in the table (peak 2 vCPU, 4 GB), and less for the rest. The install wizard pre-selects the right plan for you.
