Requestly Launches: Open-Source API Mocking & Testing Tool for Developers 🚀

Requestly recently launched!

‍

^{"A better alternative to Postman & Charles Proxy"}

‍

^{TL;DR: Requestly helps developers build faster by intercepting, mocking, and testing API responses. No more waiting for backend developers, struggling with flaky staging environments, or fighting over API contracts. With 200,000+ active installs, Requestly is trusted by Google, Amazon, Workday, Indeed, and many other Fortune 500 companies.}

Founded by Sachin Jain & Sagar Soni

Hey founders! Meet Sachin and Sagar.

What started with a simple Chrome extension to solve one simple use case has evolved into a complete API Testing & Mocking platform - now used by more than half of Fortune 500 companies.

The Problem

Frontend developers face two common problems during their local development: Dependency on backend developers (i.e. Waiting for APIs) and Unstable backend services.

Whether it's:

• The backend team still building the endpoint
• API not returning the data required for the development
• Flaky Staging/Backend servers being used for local development
• Need to modify API responses for testing error paths in frontend codebase

This leads to delayed releases, blocked sprints, and frustrated developer experience.

‍

Enter Requestly

Requestly lets you intercept, mock, and test API responses in browsers and mobile apps.

Core Features:

• Mocking API Responses: Instantly mock any API response without touching the backend or your frontend code.
• Testing API Responses: Quickly Test API responses with a sweet, simple API client.
• Mocking a Complete Flow: You can either create API mocks for selective requests or record a user flow and create mocks for the entire flow.
• Collaboration using Team Workspace: Save and reuse common API mocks across your teams with collaboration enabled in real-time.

‍

Why people love it

Frontend Teams: Build features without waiting for backend APIs or dealing with staging server issues.

QA Teams: Test edge cases in APIs and UI for error scenarios easily.

Backend Teams: Build, Design, Test and Collaboration on APIs.

Enterprise Ready: Used by over half of Fortune 500 companies including Google, Workday, Indeed, CapitalOne, MasterCard, and AutoDesk.

Other Common Use-Cases

1. Overriding JS Bundles. While talking to the enterprise users, the Requestly founders discovered that Overriding JS bundles from production to local/staging environments is one of the major use cases. They do this to test their local code changes directly on the production website by overriding the JS assets.
2. API Testing. The founders ended up building a sweet, simple API client for Requestly customers for basic API testing, and now this has become a core feature of the product. Requestly already offers capabilities like Collections, Environments, Workspaces, and Collaboration.

Testimonial

"Requestly is an incredibly useful tool for developers working on a large team with multiple staging envs, or numerous app endpoints for various APIs in a local environment. Requestly combines all the power of complicated tools like Charles Proxy and Postman. I highly recommend giving it a try if you haven't already–it will make your dev work so much easier."

What Requestly is planning next

• Building better API mocking capabilities for Android/iOS devices & simulators. The team has already migrated some companies from Charles Proxy & Postman to Requestly and it has worked well.
• Building more API testing features like Collection Runners, Scripting, and API test cases.
• Learn how to market well. So far all of the growth has been organic. The founders did try some activities in the past but they weren't consistent.
• Improve customer success. Requestly has a lot of free and paying users but they currently do not have any process to stay in touch with them and keep collecting their feedback.
