Duotonic lets you listen to Spotify collaboratively on your desktop or mobile browser. You can either generate a link to send to a friend, or join a queue to be matched randomly. It's completely free and open source, but you must have Spotify Premium.

Hi everyone! This is a side project of mine that I developed this summer which enables collaborative listening on Spotify. I hope some people who like to listen to music with others find this site interesting.
Duotonic is completely free and open source; there are no ads or sign up. All you need to do is connect your Spotify Premium account to start using the app. I'd love for more people to...

A small extension that pulls the top landscape photo from Reddit's r/EarthPorn every day, resizes it to 1920x1080 using seam carving, then sets that to your new tab wallpaper.

Hey ProductHunt! This spring I graduated high school, and this is the second Chrome extension I've released this summer.
I got the idea for this project after reading a blog exploring the Reddit API mentioned it would be possible, but when I looked I was surprised no one had made something similar. If you like the subreddit r/EarthPorn, or just like nature pictures in general, then give this...

Hey Producthunt!
This spring I graduated from high school, and using Google Classroom over the last four years, I've always been surprised by it's lack of seemingly basic organizational tools like a search bar.
