I Built a Free App Store Screenshot Tool in a Few Hours

Every time I launch an app, there's one part I dread more than anything else.

Not the code. Not the App Store review process. Not even the marketing.

It's the screenshots.

The Problem Nobody Talks About

You've just finished building your app. Weeks or months of work. You're excited. You open App Store Connect to submit — and then reality hits.

You need screenshots. Perfect, pixel-precise, store-ready screenshots.

So you open Figma, or Canva, or some paid screenshot tool. You spend an hour fighting with templates. You export at the wrong size. You redo it. You finally get something decent — but it took three hours and killed your momentum completely.

I've done this every single time I've launched an app. And I got tired of it.

So I Just Built It

I'm Mayur — an indie developer from Pune, India. I build products because I hit walls and need doors.

This time the wall was App Store screenshots.

So I built Screenshots — a free, open source tool that does one thing perfectly: wraps your app image in a beautiful, store-ready frame and exports it at the exact dimensions you need.

Upload your image. Pick a background. Adjust padding. Download.

That's it. Under 10 seconds.

No Photoshop. No signup. No watermark. No subscription. Free forever.

What It Actually Does

I wanted to keep it simple but powerful enough for real use:

  • Multi-platform sizes — iOS, iPadOS, macOS, Android, Windows presets built in
  • 25 background presets — gradients, solid colors, custom color picker
  • Live preview — see exactly what you'll get before downloading
  • Batch export — upload multiple images, download as ZIP
  • Zero backend — everything runs in your browser, nothing leaves your device
  • MIT licensed — use it, modify it, ship it

Built with React 19, TypeScript, Vite, and Tailwind CSS. Pure client-side Canvas API rendering.

I Recorded the Demo in 3 Minutes

Here's something I find funny in hindsight.

I recorded the entire Product Hunt demo video using CamPrompter — my own Mac recording studio app. It took 3 minutes. No cuts, no editing, just a clean screen recording with my talking head.

Then I launched Screenshots on Product Hunt.

Woke up to organic upvotes from 5 different countries — India, Nigeria, United States, Russia, Georgia.

15 real users in under 4 hours. Zero marketing. Zero paid ads. Zero Reddit posts.

My own tool helped me launch another tool. That felt right.

The Numbers After Launch

  • 15 active users in first 4 hours
  • 5 countries with zero marketing
  • 4 GitHub stars organically
  • Product Hunt upvotes without asking anyone personally
  • ₹0 spent on promotion

I'm not sharing this to brag. These are small numbers. But they're real, organic, and from people who genuinely found and used the tool.

That signal matters more to me than any paid acquisition number.

Why Free and Open Source?

Because I built this for myself first.

If it helps other indie developers save even 10 minutes per launch — that's enough. The GitHub star is enough. The thank you message is enough.

I'm not trying to build a business around Screenshots. I'm trying to build goodwill in a community of builders who help each other.

Open source also means you can verify the code, trust that nothing shady is happening, and contribute if you want to make it better.

What's Next

Screenshots will stay free forever. I'll keep improving it based on feedback.

If you want to support the project — star the GitHub repo. That's genuinely the best thing you can do.

And if it saved you time or a Photoshop subscription — consider buying me a chai ☕

I'm also building CamPrompter — a complete Mac recording studio for content creators, and Password Folder — an offline Mac password manager. Both born from the same philosophy: build what you need, share what works.
