introducing copyparty, the FOSS file server
Why Hacker News recommends it
HN commenters call it a model demo video and the quickest way to see how much one developer packed into a self-hosted file server.
What it is
The author of copyparty introduces the FOSS file server he has built over five years, demoing its features such as resumable uploads, WebDAV and deduplication. The video itself is shown running on a demo server.

Copyparty is an amazing piece of software. I recommend watching the recent YouTube video for an overview[0]. The developer is a personal friend and my household is proud to own one of 20 limited edition copyparty disc releases. [0] [this video]

You'll have to decide on what kind of angle to approach it from: cold and 'just the facts' or light and funny using appropriately light and funny demo material, or somewhere in between.

Recent example of a great demo video that's gotten positive commentary on HN and in the YT comments: [this video] (this has the advantage of being a wizard-level piece of software). Also, use those differentiation examples on the homepage with the same "slide to show the difference" effect that the existing ho
