I'm open sourcing Fuz.io, a project I've been working on (very off and on) for a couple years. Fuz.IO was born at a hackathon, and out of my own realization that sending large files from one person to another was pretty broken. I think this is something that a lot of people have noticed (and it has improved a lot since I started the project - many of the ideas that I had for fuz.io have since shown up in other web services).
Basically, when I started fuz.io, there was no simple way to send a large file over the internet that didn't involve an awful lot of waiting. You could use yousendit.com (side note: hightail? really?), but that meant a long wait while the file uploaded, and then another long wait while the file downloaded. You could use an IM client, but then you both needed to have it installed. You could use FTP, but then someone had to set up a server (and FTP isn't very firewall-friendly).
There weren't great options.
With Fuz.io, the idea was: drag a file on to the browser, send your friend the link, and he or she can start downloading while you upload. Super simple - no installation, no accounts, no plugins, no firewalls. It just works, using something that everyone has: a normal web browser.
I thought this was a cool idea, so my original plan was 'monetize it!' Let users create accounts, sell them for $5/month for 10gb (or whatever), and so on. I spent time thinking about business model, wrote lots of notes, etc.. Initially, I coded toward that objective.
However, even then, I was a bit nervous about the competition in the space - when it comes right down to it, the winner in the file-transfer-service wars is going to come down to some optimization of: storage and bandwidth costs, vs. stickiness of service. Dropbox is doing so well because it's sticky. Other services are competing by optimizing how they manage their storage and bandwidth costs (or by simply running at such a scale that it really doesn't matter much, see: google and microsoft). I felt that, as a single developer with no funding, the file-transfer space was probably a losing battle.
Why Open Source?
I'm open-sourcing fuz.io just in case anyone out there finds it interesting. I'm not sure I'm going to be devoting a whole lot more time to it: I've accomplished most of my goals with fuz.io, and am planning to move on to other things. I may add a few of the things listed on the github page, in the 'todo' list, just to really finish things off, but basically: fuz.io isn't going to make me money, and I want to learn some new stuff.
I may do some more tech-related blog posts about fuz.io in the future. We'll see.
