R2 Storage Manager for Cloudflare

R2 Storage Manager Lite enables restricted file management between WordPress and Cloudflare R2 using its S3-compatible API.

Upload files to your R2 bucket, browse stored objects, and generate expiring signed download links — all from your WordPress dashboard.

Unlike traditional storage solutions, this plugin ensures that your files remain private and are only accessible through controlled, time-limited URLs.

• Basic File Browser – View and manage stored files from the admin panel.
• S3-Compatible API – Fully compatible with Cloudflare R2 infrastructure.
