Company Overview

Bruno is an emerging open-source API client created and open-sourced by developer Anoop M D in 2022/2023. Bruno is built on a core philosophy of offline-first and Git-friendly design — all API collections are stored as plain text files (Bru format) locally, naturally compatible with Git version control, requiring no cloud account to use. Licensed under MIT, Bruno aims to be a lightweight open-source alternative to Postman and has quickly gained traction and reputation in the developer community.
