Hi everyone! 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. You can upload images via drag & drop, clipboard paste, file picker, or Finder right-click, all within a fully sandboxed MAS app. 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. Zero third-party dependencies. Happy to answer any questions! You can also reach me at support@picone.one
