What started as a small Chrome extension is now trusted by the world’s best tech teams.

These Indian-origin founders made the frontend developers’ dreams come true.

In 2019, two developers — Sachin Jain and Sagar Soni — were building frontend features for websites.

But they kept running into the same frustrating problem.

Every time they made a change, they had to redeploy the code just to see if it worked.

So, Sachin built a Chrome extension. It was meant for personal use. Just a tool to save time.

Over time, more and more developers started facing the same issues.

Every time someone wanted to test something on the frontend, they had to wait for the backend team to finish the API.

So the tool kept evolving.

It slowly turned into a full SaaS platform that supported API mocking, request and response interception, and more.

They formally launched the SaaS product, Requestly.

You could use it to quickly test things, change how a page behaves, and simulate stuff without needing any real backend code.

Developers loved how easy it was.

Unlike traditional tools like Postman and Charles Proxy that relied on heavy desktop setups,

Requestly took a browser-first, Chrome-extension-based approach.

It was faster, simpler.

In 2022, Requestly got into Y Combinator’s Winter batch and raised $125,000.

They raised more funding from Neon Fund, Titan Capital and PeakXV Surge.

By 2023, it had over 200,000 developers using it, including teams at Google, Amazon, Workday, and Indeed.

More than half of the Fortune 500 companies were using it.

This browser-native approach, combined with a passionate developer community, caught the attention of BrowserStack, one of the world’s biggest testing platforms.

And in 2025, BrowserStack acquired Requestly.

From a personal pain point to a small Chrome extension to becoming the default tool for mocking and testing APIs.
