Where each one falls short

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

Authelia

  • Depends on a reverse proxy: it is not a standalone identity provider
  • Configuration is YAML-first with no administrative interface, so changes mean editing files
  • Not a full IAM: user management, provisioning and federation are limited compared with Keycloak
  • Scales poorly as an organisation-wide identity solution, which is not its target

Vim

  • Configuration system uses keyboard mappings with no graphical interface for settings
  • Requires browsing documentation to modify even basic settings
  • Lacks sensible defaults for many common configurations
  • Plugin ecosystem stability varies widely depending on custom configuration complexity

Authelia: Does Authelia need a reverse proxy?

Yes. It integrates through forward authentication with Nginx, Traefik, Caddy or HAProxy rather than sitting in front of traffic itself.

Vim: What platforms does Vim support?

Vim runs on Unix-like systems (Linux, macOS, BSD), Windows (7, 8, 10, 11), VMS, and is available through package managers or standalone installation on all major operating systems.

Authelia is far lighter and aimed at protecting self-hosted services behind a proxy. Keycloak is a full identity and access management platform, and much more to run.

Vim: Who maintains Vim now?

Vim was created by Bram Moolenaar, who passed away on August 3, 2023. Christian Brabandt is the current lead maintainer, and the project continues with volunteer contributors.
