Independent · Privacy-first · Based in India

Hi, I'm Aman.

I'm an indie developer who makes small, focused tools - Chrome extensions, web apps, the occasional mobile app. Things I'd want to use myself, that don't try to be sticky.

Chrome Audio Capture is the largest of those: 20,000+ Chrome users, a 4.2 rating on the Web Store, and as of 2026 a real Pro tier so I can keep working on it full time.

Great software solves one problem brilliantly, runs locally, and stays invisible. That's the philosophy behind everything I build.

The story

Why I built Chrome Audio Capture

From an annoying everyday problem to a product 20,000+ people use - in four chapters.

Chapter 01

The problem

Recording a browser tab's audio used to mean installing a desktop app, configuring virtual audio cables, or paying for screen-capture software that recorded video you didn't need.

For something as simple as "save this lecture or call as MP3," the available tools were either overkill or invasive.

Chapter 02

My take

One click - the tab's audio is captured locally. Another click - an MP3 lands in your Downloads folder. No upload, no cloud, no account required for the free tier.

That's it. That's the product.

Chapter 03

How I make money

Honestly: by selling a Pro upgrade to people who hit the 60-minute free cap, need to record multiple tabs in parallel, want lossless WAV, or use the built-in audio editor and its 20+ studio effects.

I don't run ads, don't sell user data, and don't bundle the extension with anything. Pro is a recurring subscription billed by Paddle as Merchant of Record. That's the whole business model.

Chapter 04

Where I work

I'm based in Ranchi, India. Service infrastructure runs on Supabase (ap-south-1, Mumbai) and Cloudflare's global edge.

Billing is handled by Paddle.com Inc., the Merchant of Record on your card statement - they handle taxes, fraud prevention, and chargebacks worldwide.
