Each tool has its own unique features and advantages, and the right choice will depend on your specific needs and preferences.

If you're only testing gRPC, Kreya is a great choice. Its test data generator is a unique feature that sets it apart from other tools.

Kreya's test data generator can handle strings, UUID, and other fundamental data types, making it a convenient option for gRPC testing.

Postman and Insomnia, on the other hand, are primarily designed for HTTP API testing, with gRPC being just one of many features. They have a lot of additional features for easy writing of API tests, but may not be the best fit for gRPC-specific needs.

All four tools can be easily installed as desktop applications. In the author's experience, this was done on Windows 11.

BloomRPC has limitations when it comes to importing proto files, specifically via server reflection. However, importing files works perfectly fine.

Insomnia is inconvenient in that it can't get a request template based on the proto schema. You have to search for it yourself and insert it as a JSON file.

Kreya.app has a unique feature - a built-in test data sampler for strings, UUID, and other fundamental data types.

Postman has a limitation in its beta version, where created requests can't be saved. However, this is expected to be fixed in future releases.

Kreya and BloomRPC are strictly focused on gRPC, whereas Postman and Insomnia have a broader focus with gRPC being just one of many features.
