A couple of years ago, I had an interesting idea. What if there was a marketplace where all the underlying tech was open-source? The order management system, the storefront, customer support, etc. The marketplace would simply connect to the seller’s infra instead of locking them in. If, for some reason, the seller is removed from the marketplace, their software stays with them and they can continue accepting orders directly.

Which ones, how much, and on which platforms? So we…

Hey HN! I'm the developer of one of the most popular Android clients for HN, Harmonic for Hacker News. Over the years I have recieved many requests to open source the app which I am finally doing - sorry about taking so long :) Having been very busy working on my PhD during the last two years - Harmonic has not recieved the attention it deserves. I therefore hope that open sourcing it can give it a new lease on life. I also hope that by posting here many of the nice people who have reached out to me will notice that the app is finally open source. I'm also happy to answer questions about the…
