What is Bruno?
Bruno is a fast, open-source, offline-first API client that has become a popular alternative to heavier tools like Postman. Its defining feature is that it stores your request collections as plain text files right in your project folder, so they live in your git repository alongside your code — versioned, diff-able, reviewable in pull requests, and shared with your team the same way you share code. For developers, having API requests version-controlled next to the code they test is exactly how it should work.
Because it is offline-first and open source, Bruno just works without an internet connection or an account wall for basic use, and you can trust it, inspect it, and avoid vendor lock-in. It covers everything most developers need — building and sending requests, organizing collections, managing environments and variables, writing tests, handling authentication, and working with REST, GraphQL and more — while staying light and snappy. It opens instantly and stays responsive, a daily relief compared with the weight and cloud-lock-in that frustrate many Postman users.
Bruno suits individual developers and teams who collaborate through git and value speed, privacy and open source. It can import existing Postman collections, so trying it costs almost nothing. While large enterprises may still want Postman's deepest collaboration and lifecycle features, for everyday API testing Bruno is simply a nicer, lighter, more private experience. If Postman's growing weight, cloud lock-in or account requirements have been bugging you, Bruno is the git-friendly, offline, open-source client worth switching to.
What is Insomnia?
Insomnia is a clean, capable API client that helps developers design, test, debug and interact with APIs — supporting REST, GraphQL, gRPC and more. Testing and exploring APIs is a constant part of modern development, and Insomnia provides a streamlined, pleasant environment for sending requests, inspecting responses, managing environments and variables, and organizing your API work, making it a popular alternative to heavier API tools for developers who value simplicity and a good experience.
With Insomnia, you can craft and send API requests of all kinds, handle authentication, use environment variables to switch between setups (like development and production), and organize requests into collections for your projects. It supports REST, GraphQL and gRPC, so it works across the different API styles developers encounter, and it offers features for designing APIs, generating code, and collaborating with teammates. Its focus on a clean, fast interface and a smooth workflow makes everyday API testing and debugging efficient and less tedious, which developers appreciate. It's available as a desktop app and fits naturally into development workflows.
Insomnia is used by developers and teams who work with APIs regularly — building, integrating or testing them — and want a capable, well-designed client that's lighter and more focused than some alternatives. By making it easy to send requests, manage environments, and debug across REST, GraphQL and gRPC, it speeds up the API work that's central to so much development. Its balance of capability and simplicity, along with collaboration and design features, makes it suitable for both individual developers and teams. As APIs remain fundamental to how software is built and connected, good tools for working with them are essential. For developers who want a clean, powerful client for designing, testing and debugging their APIs across multiple protocols, Insomnia offers a capable, pleasant and widely-used solution.
