Alternative Storage Adapters

If you’re not deploying to Vercel, you’ll need to implement a different storage adapter. PayloadCMS supports various storage solutions including:

  • AWS S3
  • Google Cloud Storage
  • Local filesystem

Refer to the PayloadCMS documentation for implementing alternative storage adapters.
