Introduction
APIs (Application Programming Interfaces) are the backbone of modern software applications, facilitating communication and data exchange between different systems. Ensuring your APIs’ reliability, correctness, and performance is paramount to delivering high-quality software. Two popular tools that help developers and teams achieve these goals are “Insomnia” and “Postman”. So, which is best? In this blog post, I’ll dive into what Insomnia and Postman are, explore their key features, and compare them to help you choose the right tool for your API testing and debugging needs. This will be a fun Insomnia vs. Postman roundup.
