Bruno
WindowsOpen-source, privacy-first API client for developers
Overview

Features include intuitive request building, environment variables, dark/light mode sync with Windows themes, and support for OAuth2, JWT, and API keys. Integrates seamlessly with Windows File Explorer (associates .bru files) and can be installed via winget or official EXE. No mandatory cloud sync—keep your API data local and secure, with optional Bruno Hub for team collaboration.
