Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

GitLab

  • Baseline requires 8 vCPU and 16 GB RAM for single-node installations; resource-intensive
  • PostgreSQL is mandatory; no support for alternative databases
  • Redis or Valkey cache required; adds infrastructure complexity
  • High-availability deployments require inter-node latency below 5 ms; difficult to achieve across geographically distributed sites
  • Requires self-hosting and maintenance; GitLab.com SaaS only available to GitLab team members for administration

Keycloak

  • Requires self-hosted deployment and operational expertise to install, configure and maintain
  • No managed cloud option provided by Red Hat; organisations must operate infrastructure themselves or use third-party distributions
  • Clustering and high-availability configurations require additional operational knowledge
  • Community support only; commercial support requires third-party vendors or distributions
