I found this in their hiring page regarding file uploads. > We’ve implemented cross-platform Drag and Drop file uploading. When you drag a file into a Mighty window on macOS, we simulate that same sequence of Drag-and-Drop events on Linux. We trick Chromium into thinking it's uploading a file from the Linux filesystem while, behind the scenes, we stream the file from the user's Mac; we accomplish this using Filesystem In Userspace (FUSE).
