More about Requestly

Requestly is a developer-focused platform providing tools to intercept and modify HTTP/HTTPS requests, aimed at accelerating the development and testing lifecycle. The company was founded in 2021 by Sachin Jain, Sagar Soni, Sahil Gupta, and Ritesh Arora. The idea for Requestly originated as a side project by Sachin Jain, who, drawing from his experience as a developer at Google and Adobe, sought a way to test local JavaScript code changes directly on live production websites without waiting for staging environment deployments.

Co-founder and CEO Sachin Jain previously worked at Google, Adobe, and Grofers, bringing over a decade of industry experience to the venture. Co-founder and CTO Sagar Soni has a background in software development and entrepreneurship, having previously founded CollegeAdviser. The founding team's collective experience fueled the evolution of a simple Chrome extension into a comprehensive API testing and mocking platform. The company is an alumnus of Y Combinator's Winter 2022 batch and also participated in Peak XV's (formerly Sequoia India) Surge program. In May 2025, Requestly was acquired by BrowserStack, a cloud testing platform, to enhance BrowserStack's suite of developer tools.

Requestly's business model is centered on a freemium structure, offering a free open-source version alongside paid subscription tiers (Lite, Basic, Professional) for individuals and teams needing advanced features and increased capacity. The platform generates revenue through these subscriptions, which unlock capabilities like unlimited rules, team workspaces, and priority support. It serves a global user base of over 200,000 developers and quality assurance teams in more than 10,000 companies, including many Fortune 500 firms. The primary clients are frontend developers, QA engineers, and support engineers who use the tool to debug issues, test edge cases, and demo new features.

The core product is a lightweight proxy available as a browser extension for Chrome and Firefox and as a desktop application. It allows users to intercept, modify, and mock API requests and responses without the complexities of traditional proxy tools like Charles Proxy or Fiddler. Key features include the ability to modify HTTP headers, redirect URLs, switch hosts, mock API responses with custom data and status codes, inject custom scripts, and modify API request bodies. For collaborative efforts, Requestly offers Team Workspaces where developers can share rules and configurations, streamlining testing and debugging across teams. The platform also includes an API client for testing, the ability to import collections from Postman, and support for intercepting traffic from iOS devices and simulators.
