S3nding is a lightweight macOS app that turns any S3-compatible bucket into a fast file-sharing tool. Instead of uploading files to third-party cloud drives, you upload directly to your own S3 storage and instantly get a shareable link. It supports AWS S3 and any S3-compatible provider, works quietly in the background, and is designed to be as fast and frictionless as possible. No sync folders. No complex dashboards. Just upload → get link → done.
