The short version

  • Only Authelia has a free tier, so it costs nothing to try first.
  • Each has a real cost: Authelia depends on a reverse proxy: it is not a standalone identity provider; GitHub Copilot agent mode lacks deep tool orchestration and iterative execution compared to specialized agentic tools
  • They diverge on capability: Authelia covers Reverse proxy integration, GitHub Copilot covers Code completion.
  • Prices and features above were last checked on 30 August 2026.

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

GitHub Copilot

  • Agent mode lacks deep tool orchestration and iterative execution compared to specialized agentic tools
  • Suggestions for niche or specialized programming languages are less accurate due to limited training data
  • Less effective with non-English prompts or grammatically incorrect developer instructions
  • Free tier severely limited to 2,000 completions and 50 chat requests per month
