Bruno | A Git-Friendly, Offline-First API Client Built Right Into VS Code

Hi everyone! I’m thrilled to introduce [Bruno] ... a fast, lightweight, and open-source API client integrated into VS Code that makes API testing and development smoother and more efficient. Our desktop app is used by ~2 million devs and we've been keen to provide this extension as well.

This is a fresh version of our extension that was previously just syntax highlighting.

If you’ve ever toggled between your code editor and a separate API tool, Bruno is here to change that. Here’s why it stands out:

---

Why Bruno?

• Git-Friendly: Bruno uses .bru files stored directly in your workspace. They’re plain text so version control is natural, diffable, and merge-friendly.
• Offline-First: No cloud lock-in or third-party dependencies. Your collections and environments stay local and under your control.
• Open-Source & Free: Transparency, community-driven features, and zero cost.
• Fast & Lightweight: Designed to launch and run in the same editor you already love - no bloat, no fuss.

---

Core Features

• Ad-hoc request creation for quick debugging
• Seamless .bru editing with both GUI and editor modes
• Inline API testing inside VS Code
• Easy collection management and organization

Advanced Capabilities

• Environment variables for flexible setups
• Pre-request and post-response scripting
• Robust authentication (Basic, Bearer, OAuth)
• GraphQL support with syntax highlighting
• Multipart requests and file uploads
• Unlimited Collection Runner

Whether you're testing REST services or crafting complex GraphQL queries, Bruno gives you the full power of a standalone API tool—right inside your editor.

Why This Matters

• Developers Save Time: No more switching apps, stay focused in VS Code.
• Teams Gain Precision: Version-controlled API specs reduce drift, merge conflicts, and onboarding friction.
• Data Stays Yours: With offline-first and local storage, your work remains private and resilient.

Looking Ahead

Imagine Bruno becoming the go-to tool for API workflows in VS Code particularly in enterprise and remote settings where offline-first reliability matters. I’m eager to explore partnership opportunities, feature spotlights, or guest contributions on Microsoft’s developer blog.
