Pail

Pail is a desktop application for working with S3-compatible object storage. It is free and open source under the MIT License, and runs on Windows, macOS and Linux. The project positions itself as a graphical alternative for users who need to browse buckets and manage files without relying solely on command-line tools.

The app covers common storage operations: uploading and downloading files, folders or entire buckets, with separate queues that show progress, speed, cancel and retry controls. Large files are uploaded in parts with checksums, and downloads are verified before being moved into place. Pail also handles object versions and delete markers, allowing users to list older versions, restore them, undo deletes or permanently remove specific versions. Bucket settings and share links are managed from the same interface.

Pail is tested with Amazon S3, Cloudflare R2, MinIO, Wasabi and VersityGW, and other S3-compatible services can be added via a custom endpoint. This makes it suitable for developers, system administrators and small teams who work across multiple storage providers and want a consistent desktop experience.

For best results, users should confirm that their storage provider supports the S3 API features they need, such as versioning, before relying on those functions. The project is at version 0.2.0, so checking the documentation and release notes is advisable. Overall, Pail is a focused, no-cost tool for everyday S3 storage management on the desktop.
