Kreya, a Postman Alternative

In plain words

Kreya is a development tool for testing and interacting with APIs, supporting both gRPC and REST protocols. It is designed for developers who need an alternative to Postman with a clean interface that handles advanced use cases. The tool includes features like innovative authentication approaches and API importers, initially built to overcome limitations in existing gRPC tools.

In the maker’s words, at launch

Hi HN! For over a year we've been working on Kreya. At first, it only supported gRPC, because the alternative tools (eg. BloomRPC) were very limited in their functionality. Since then, we have added many features, trying hard to keep the UI clean while still supporting advanced use cases. Yesterday, we released Kreya v1.8, which added support for REST! In our opinion, Kreya is a good alternative to the existing tools out there. Sure, it may not support all the features that Postman has. But we think that Kreya has some innovative approaches (eg. authentication or API importers) that users may find interesting.

  Pipes puzzle (a.k.a. Net) on a hexagonal grid▲537

  Hello, HN - I wanted to share this puzzle game I made during my vacation. I'm rather fond of the pipes puzzle where your goal is to restore a scrambled network of connections by rotating tiles. It's usually played on a grid of squares and this all started when I decided to make a programmatic solver for that kind of puzzle. Then I realized that with some minor changes the solver could generate new puzzle instances. I thought about what kind of puzzle to make and someone suggested a hexagonal grid. Adapting the generator wasn't too hard but then I had to create a way to play this variant. So…
