Lessons, Innovations, and the Road Ahead with Bruno

Session Abstract:

Over the last four years, Bruno has redefined what an API client can be.

By pioneering a file-based, Git-native, local-first model for managing API requests, Bruno introduced a developer-centric alternative to the cloud-heavy tooling that dominates the space.

In this talk, we’ll walk through a technical retrospective - what it took to build a file-based API client from the ground up, the design decisions that shaped it, and the tradeoffs we made along the way.

We'll also unveil OpenCollection: A new open standard for representing API collections.

Designed to be portable, extensible, and versionable, OpenCollection paves the way for open tooling, deeper integrations, and collaboration across teams and tools.

About Bruno:

Bruno is a Local-only, Git-friendly and OpenSource API client. Unlike other tools that rely on cloud based collaboration, Bruno embraces the simplicity of the filesystem based approach along with Git to enable seamless sharing and version control of API Collections.

The project has garnered over 34,000 Github stars, has over 300 contributors and is used by over half a million developers every month. We continue to push the boundaries and are innovating on providing better developer experience while working with API's

Key Topics Covered:

Technical Retrospective

Lessons learned from four years of building and scaling a file-based API client - covering architecture, file formats, performance, editor integration.

OpenCollection: An Open Standard for API Collections

A deep dive into the OpenCollection specification - its schema, validation model, and how it's designed for interoperability across tools, systems, and workflows.

Static Documentation from Collections

How to generate clean, dependency-free API documentation directly from local request files and publish it anywhere, without relying on any backend infrastructure.
