📄 Description

Summary

  • Add a warning log when baseURL is not provided in options
  • Helps developers debug redirect URI issues in production or multi-domain environments

Context

When baseURL is not explicitly set, Better Auth falls back to inferred values from environment variables or request headers. This can cause incorrect redirect URIs, especially in:

  • Production environments
  • Multi-domain setups
  • Proxy configurations

This change adds a clear warning message to help developers identify the issue quickly.

Test plan

  • Verified the warning is logged when baseURL is not provided
  • Verified existing tests pass
  • Verified lint passes

Closes #6780

Summary by cubic

Log a clear warning when baseURL is not provided, instead of silently relying on inferred values. This helps developers diagnose incorrect redirect URIs in production, multi-domain, and proxy setups and encourages setting baseURL explicitly.

Written for commit 96e9f2c4ad. Summary will update automatically on new commits.
