Dropper

Dropper is a macOS menu bar application that turns your own Cloudflare R2 storage into a personal file sharing service. You drag files onto the menu bar icon, and Dropper uploads them directly to your R2 bucket, placing a shareable link on your clipboard within seconds. The files stay on infrastructure you control rather than some third party's servers, and the links are short, unguessable URLs with no login walls or countdown timers.

The problem it solves is a familiar one for anyone who shares files regularly. Third party services impose limits, show ads, require accounts, or store your data on servers you have no visibility into. Dropper sidesteps all of that by letting you use your own Cloudflare account as the backend. R2's free tier covers 10 GB of storage, so for light use the only cost is zero, and for heavier use you pay Cloudflare directly at known rates.

Beyond basic uploads, Dropper handles a lot of the friction that usually comes with sharing files on the web. It automatically converts HEIC photos to JPEG, AIFF audio to WAV, and MOV or HEVC video to web-friendly MP4 so recipients can open files in a browser without special software. When someone opens an audio link, they get a SoundCloud-style player with a waveform. Video links get a proper player. Image galleries get a lightbox. The experience on the receiving end feels polished, not like a raw file dump.

There is also a built-in screenshot editor with markup tools, shapes, text, and multiple colors. If you grab a screenshot and want to annotate it before sharing, you can do that without opening another app. For grouping files, Dropper supports collections, which let you bundle multiple files under a single link. You can archive old shares, pin important ones, and browse through folders to keep things organized over time.

The target user is anyone on a Mac who shares files often and wants ownership over where those files live. Developers, designers, and power users who already have a Cloudflare account will feel right at home. If you have never touched R2, setup requires creating a bucket and generating API credentials, which takes a few minutes. Once that is done, Dropper handles everything else.

What sets it apart from alternatives like Droplr or CloudApp is the self-hosted posture. There is no subscription because there is no middleman. The app itself is completely free. You are paying Cloudflare for storage if you exceed the free tier, not paying Dropper for the privilege of uploading. That makes it cheaper in the long run and means your links stay alive as long as you keep the bucket around.

Dropper requires macOS 14 or later and runs on both Apple Silicon and Intel Macs. Support and updates come through the project's GitHub repository rather than a traditional support desk. For anyone who wants a fast, private, low-cost way to share files without handing data to a service you do not control, Dropper is worth a look.
