It is with a heavy heart that I announce the closure of PrayBook by NK, effective March 31, 2025. This decision was not made lightly, and I want to express my deepest gratitude to all our users for their support and engagement over the years.
In this blog, I’ll be diving into three key technologies of modern client-server development: WebSockets, GraphQL, and REST APIs. While there are other architectures like RPCs (Remote Procedure Calls) that also play a significant role, I’ll cover those in a future post.

PrayBook by NK is an inclusive prayer app for all faiths. Manage, share, and explore prayers and spiritual places with Apple Maps integration and AI enhancements. PrayBook also have several Third Party integrations.
This time, I decided to play dirty pushing the limits and testing what happens when you go all-out reckless. Expect chaos, intense firefights, and, yeah... a lot of my in game deaths.
