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 MerchantDiff?
