Full disclosure: I work at Courier.
Courier Inbox comes with web and mobile SDKs that are highly customizable, and we wanted to push the limits and see what we could build using them. We landed on the idea of Puppygram, an Instagram clone that displays nothing but pictures of cute puppies. We built the server using Next.js, Random.dog and Inngest.
We wrote-up a technical tear-down blog post [1] and have posted all source code [2] [3] on Github.
Happy hacking!
