Keycloak
Combine filters →Keycloak is a Java identity server, the sign-in front door for other applications. It needs a JVM heap of a gigabyte or more and a stable hostname with TLS, since every client is configured against its URL and a change breaks them all. Production installs put PostgreSQL behind it. Java hosts and container platforms carry it; shared hosting does not.
1 provider documents support for Keycloak, listed alphabetically. All of them shared hosting. 116 records do not record this field, and cannot appear here either way.

Uberspace is a small German hosting service sitting between shared hosting and a VPS, running since 2011, with a shell account and a documented stack.
Do I need special hosting for Keycloak?
In most cases, no. Keycloak runs on any host that supports its runtime. This list is shorter than that: it holds the providers that document Keycloak themselves, with an installer, a guide or a maintained image. Other hosts may run it without mentioning it.
What should I check before hosting Keycloak?
The runtime versions on offer, how deploys work, whether there is a shell for command-line tools, where cron jobs run, and which databases come managed. Check backups too, and how to move away later.
Who is the best Keycloak hosting provider?
We don't know. A static portfolio and a busy shop need different things from a host, and so do a freelancer and an agency with forty client sites. Nobody pays to be listed here and the order is alphabetical. The guide covers what to compare.
