What Hoppscotch does

Hoppscotch is an open-source API development ecosystem founded in 2021 in Thiruvananthapuram, Kerala, India. The company provides a browser-based platform for building, testing, and documenting APIs, supporting multiple protocols including REST, GraphQL, WebSocket, Server-Sent Events (SSE), Socket.IO, and MQTT. Unlike desktop-based incumbents such as Postman, Hoppscotch runs entirely in the browser with no installation required, and is supplemented by Chrome and Firefox browser extensions and a desktop Agent application supporting HTTP/HTTPS/SOCKS proxies with NTLM and Basic Auth authentication.

The core product portfolio includes the Hoppscotch web application for REST API testing, dedicated GraphQL and WebSocket (real-time) interfaces, Mock Servers for simulating backend endpoints, built-in documentation generation, and pre/post-request JavaScript scripting with environment variable management. Reported users include Google, Microsoft, Salesforce, and IBM, though these are not validated as paid enterprise customers. The company is led by co-founders Liyas Thomas (CEO) and Andrew Bastin (CTO), with Kiran Johns as Product Manager, and operates with a headcount of 11-50 employees.

The business model is freemium open-source: a free tier is publicly available at hoppscotch.io with full core functionality for individual developers, and an enterprise or commercial tier is inferred but not publicly priced. The company raised a $3 million seed round in December 2021 led by OSS Capital with participation from Automattic and angel investors. No subsequent financing, revenue, or ARR figures have been disclosed.

Core offering

Hoppscotch provides an open-source, browser-based API development ecosystem that lets developers build, test, save, share, and document API requests. It supports REST, GraphQL, WebSocket, SSE, Socket.IO, and MQTT protocols in a single interface, and includes JavaScript-based pre/post-request scripting, environment variable management, mock server generation, AI Experiments, and dedicated browser extensions for Chrome and Firefox. The product is delivered primarily as a no-installation web app with companion browser extensions and a local Agent for bypassing browser sandbox limitations.

Product overview

Hoppscotch is a single open source API development ecosystem offering multiple protocol-specific interfaces: the core Hoppscotch web application for REST API testing, a dedicated GraphQL interface, and a WebSocket testing module for real-time communications. The platform also includes supporting modules such as Mock Servers for API simulation, an Agent desktop app with proxy support (HTTP/HTTPS/SOCKS including NTLM and Basic Auth), a browser extension for Chrome and Firefox, and built-in documentation generation features. Additional capabilities include pre-request and post-request scripting in JavaScript, environment and variable management, collections organization, and SSE/Socket.IO/MQTT protocol support.

Products and services

• Hoppscotch Web Application Browser-based, no-installation web application that lets developers build, test, save, share, and document REST API requests using a JavaScript scripting engine, environment variables, collections, and mock servers. Designed for individual API developers and enterprise engineering teams who want a lightweight, browser-native alternative to desktop API clients.
• Hoppscotch GraphQL Dedicated GraphQL interface within the Hoppscotch ecosystem for composing, sending, and testing GraphQL queries, mutations, and subscriptions against GraphQL endpoints. Built for API developers and engineers working with GraphQL-based services who need a browser-native GraphQL client alongside REST tooling.
• Hoppscotch Realtime (WebSocket, SSE, Socket.IO, MQTT) Realtime protocol interface within Hoppscotch for establishing and testing WebSocket, Server-Sent Events (SSE), Socket.IO, and MQTT connections. Targeted at developers building or consuming realtime APIs and event-driven services who want a single tool to cover streaming and pub/sub protocols alongside REST and GraphQL.
• Hoppscotch Browser Extension Standalone Chrome and Firefox browser extension distributed through the Chrome Web Store and Firefox Add-ons marketplace that integrates Hoppscotch's API testing capabilities into the browser via an interceptor architecture, enabling cross-origin API testing and tighter developer workflows.

Direct peers

• Insomnia: Open-source API client (now under Kong) supporting REST, GraphQL, gRPC, and WebSocket. Directly comparable on multi-protocol coverage and open-source ethos.
• Postman: Category-leading API client and collaboration platform supporting REST, GraphQL, and WebSocket testing. Hoppscotch is positioned as the open-source, browser-native alternative to Postman.
• Bruno: Open-source API client that stores collections as local files. Competes with Hoppscotch for developer mindshare around open, git-friendly API testing workflows.
• Thunder Client: Lightweight VS Code-native API client. Targets the same developer persona as Hoppscotch but competes on IDE integration rather than browser-based delivery.

Broad incumbents

• RapidAPI: Broader API hub and testing platform that also runs a marketplace. Overlaps on API testing and developer tooling but operates at a larger, more horizontal scope.
• Swagger: OpenAPI ecosystem (now under Linux Foundation) for API design and documentation. Adjacent to Hoppscotch's documentation and testing modules within the broader API tooling stack.
• ReadyAPI: SmartBear's enterprise API testing suite. Targets the same enterprise QA and testing use cases that Hoppscotch's paid tier would compete for.
• Stoplight: API design, documentation, and testing suite with an enterprise focus. Competes for team-level API lifecycle tooling budgets that Hoppscotch's enterprise tier targets.
• Apigee: Google's enterprise API management platform. Sits further up the API lifecycle stack but competes for the same enterprise API tooling wallet.

Others

• Katalon: Test automation platform that includes API testing capabilities. Adjacent competitor rather than direct peer; relevant when API testing budgets are pooled with broader QA tooling.
