Hoppscotch: The Open Source Powerhouse for API Development

APIs are the backbone of modern digital infrastructure, and developers need reliable, efficient tools to work with them. Traditionally, this space has been dominated by heavyweight solutions like Postman or Insomnia. But Hoppscotch is changing that narrative—offering an open-source, lightning-fast, and collaborative alternative that doesn’t compromise on features.

Hoppscotch stands out with a minimalist interface that's incredibly lightweight, ensuring speed and responsiveness right from the first request you send. Unlike bulkier alternatives, it’s built to get out of your way so you can focus on testing, debugging, and building APIs without the clutter.

Built for Speed, Designed for Developers

From real-time request execution to instant previews of responses, Hoppscotch feels almost instantaneous. Whether you're sending a simple GET request or working with more complex methods like PATCH, CONNECT, or even custom-defined methods, the platform handles it all gracefully. It supports the full HTTP spectrum, which makes it ideal for both RESTful and non-RESTful API workflows.

GraphQL developers aren’t left behind either. With support for endpoint setup, schema introspection, custom headers, and multi-column documentation views, Hoppscotch treats GraphQL as a first-class citizen. The same goes for WebSocket, MQTT, Socket.IO, and Server-Sent Events, giving real-time data fans all the tools they need.

Flexible, Customizable, and Offline-Ready

One of Hoppscotch’s more underrated strengths is its customization. You can personalize the interface with themes—light, dark, black, or system-based—and fine-tune accent colors from a vibrant palette. Zen mode offers a distraction-free experience, while theme preferences and sessions sync across local and cloud storage.

As a Progressive Web App (PWA), Hoppscotch is installable on desktop and mobile alike. It loads instantly, works offline, and barely sips system resources. It’s as portable and efficient as you’d expect from a modern web tool.

From Solo Projects to Teams at Scale

Hoppscotch seamlessly scales from individual developers to entire teams. Collections let you organize requests into nested folders and sync them across devices or repositories via GitHub gists. Workspaces help you juggle personal and team environments, making context-switching a breeze.

Need to collaborate? Teams can be created with role-based access control, shared collections, and full cloud sync support. An admin dashboard gives you the insight and control you need to manage users and projects effectively.

Everything You Expect, and Then Some

Hoppscotch delivers all the expected features of a professional API tool: pre-request scripts, post-response tests, environment variable support, request history, bulk editing, code snippets for various languages, and even proxy settings to handle CORS and blocked endpoints.

Authorization is robust and flexible, supporting everything from basic auth to OAuth 2.0 and OIDC. You can even test out edge-case scenarios using custom headers, dynamic parameters, and payloads in raw or key-value formats. Once responses come back, they’re easy to explore, copy, or download—with support for multiple content types including HTML, images, JSON, and XML.

Built by the Community, for the Community

As an open-source project, Hoppscotch thrives on community input. The app is internationalized (i18n) and invites developers from around the globe to contribute translations and features. You can log in using popular platforms like GitHub, Google, or Microsoft, and keep everything synced across all your devices with real-time updates.

Hoppscotch isn’t just an open-source replacement for Postman—it’s a reimagination of what an API development tool should be in 2025: fast, elegant, inclusive, and fully in your control. Whether you’re exploring a new REST endpoint or managing a complex microservices architecture, Hoppscotch helps you move quickly and stay organized without compromise.
