Summary

PicOne is a native macOS menu bar app (built with SwiftUI) that allows users to upload images to various image hosting services without needing a full app window or Dock icon. It supports multiple upload methods (drag & drop, clipboard paste, file picker, Finder right-click) and works with many hosts including S3-compatible providers (AWS, R2, COS, MinIO), Alibaba OSS, Qiniu, Upyun, Imgur, SM.MS, WebDAV, local folders, and custom hosts. The app is fully sandboxed and uses hand-implemented signing protocols with zero third-party dependencies.

I built PicOne because I was tired of image uploaders that require a full app window, run heavy background processes, or need third-party libraries.

PicOne lives entirely in your macOS menu bar — no Dock icon, no main window.

I hand-implemented SigV4 signing for S3-compatible providers (AWS, R2, COS, MinIO), a custom V1 signer for Alibaba OSS, plus Qiniu, Upyun, Imgur, SM.MS, WebDAV, local folder, and a fully templated custom host.
