https://zimly.app is an open-source S3 media backup app that I've been working on in my free time.
The last few months I've been trying to get the real-time upload speed to display nicely, which proved to be harder than anticipated. But I think I've got a good solution now and might roll a new release today.
My goal is to have a few thousands downloads by the end of the year. Marketing is hard, also because it's less rewarding than programming features, so I tend to pick a new feature instead of writing a blog post or polishing the website.
