What Requestly does

Requestly is a developer-tooling company headquartered in San Francisco that builds a privacy-first, local-first API development platform. Its two core products are an API Client (for building, testing, and managing APIs across REST, GraphQL, SOAP, and gRPC) and an HTTP Interceptor (for debugging and modifying HTTP requests and responses in the browser and on desktop). The platform is delivered as a desktop application for macOS, Windows, and Linux and as browser extensions across Chrome, Edge, Firefox, Safari, Opera, Vivaldi, and Brave. Its technical differentiator is a local-first architecture: API collections and environments are stored as plain JSON on the developer's machine and synced through Git, with no mandatory cloud login. The product integrates with AWS Secrets Manager for credential storage, imports collections from Postman, OpenAPI, cURL, HAR, and WSDL, and supports AI-assisted test generation. Requestly holds SOC 2 Type II certification and is GDPR compliant.

The company operates a freemium product-led growth motion: the free tier supports up to 10 collaborators with full access to core features, while a quote-based enterprise tier layers on SOC 2 compliance, SSO, role-based access control, and audit logs. Distribution runs through self-serve downloads and browser-extension stores, with a parallel direct sales motion for enterprise. Named users include teams at Microsoft, Google, Amazon, Salesforce, Adobe, AT&T, Verizon, Autodesk, Vodafone, AB Tasty, Cyrisma, and Upscayl, with 300,000+ developers reported as using the product and a 4.5-star Chrome store rating across 1,700+ reviews. Co-founder and CTO Sagar Soni continues in role following the company's acquisition by BrowserStack, under whose portfolio Requestly now operates as a subsidiary product line.

Direct peers

• Postman: The dominant API client platform with REST/GraphQL support, collaboration workspaces, and a large enterprise installed base. Direct competitor to Requestly's API Client; Postman's recent mandatory login/cloud push is the opening Requestly is leveraging.
• Insomnia: Cross-platform API client (REST, GraphQL, gRPC, SOAP) with local and cloud-synced workspaces. Competes directly with Requestly on developer-focused API testing, including protocol breadth and offline workflows.
• Bruno: Open-source, Git-native API client that stores collections as plain-text files in a repo. Closest direct peer on the privacy-first, local-first, code-as-config positioning that Requestly emphasizes as its core differentiator.
• Hoppscotch: Open-source, browser-based API development ecosystem with web, desktop, and CLI clients. Competes with Requestly on lightweight, free, developer-friendly API testing across REST, GraphQL, and WebSocket protocols.
• HTTPie: Command-line-first HTTP client with a polished web/desktop UI, used for API testing and debugging. Comparable to Requestly's API Client target use case (sending requests, inspecting responses, environment management).
• Charles Proxy: Industry-standard HTTP debugging proxy for intercepting and modifying HTTP/HTTPS traffic. Direct competitor to Requestly's HTTP Interceptor product; customer testimonials explicitly compare the two (e.g., Autodesk). Paid desktop tool with established enterprise adoption.
• Proxyman: macOS-native HTTP debugging proxy with request/response interception, mocking, and scripting. Competes directly with Requestly's HTTP Interceptor on macOS developer desktops.

Broad incumbents

• Fiddler (Progress Telerik): Long-standing HTTP debugging proxy and web debugging toolkit, now part of Progress. Overlaps with Requestly's HTTP Interceptor capabilities as part of a broader developer tool portfolio.
• Katalon: Enterprise test automation platform covering API, web, mobile, and desktop testing. Adjacent competitor given QA engineer use cases Requestly serves, though broader and more automation-focused than Requestly's developer-first scope.

Emerging players

• Apidog: All-in-one API design, debugging, mocking, and testing platform with collaboration features. Emerging competitor targeting the same API development workflow that Requestly addresses, with growing enterprise positioning.
