Testing responsive web layouts shouldn't require paying $10 to $15 every month.
Like many frontend developers, I regularly rely on browser extensions to preview how sites render across different viewports, capture quick device mockups for client reviews, and record interactions. Over time, however, extensions like Mobile Simulator and Responsive Viewer started paywalling everyday necessities—locking specific breakpoints, interaction capture, or clean exports behind recurring monthly subscriptions.
I got tired of subscription fatigue for straightforward browser utilities, so I built Screenlet.
What is Screenlet?
Screenlet is a lightweight browser extension and web tool designed for developers and designers who need fast, zero-friction responsive testing and screen recording.
Instead of gating essential developer utilities behind paywalls, 100% of the core testing features are unlocked for free.
Key Features
- Complete Device Library: Test across popular mobile, tablet, and desktop viewports without hitting an arbitrary "upgrade to unlock this device" screen.
- Responsive Multi-Viewport Testing: Inspect media queries, flexbox shifts, and layout behavior instantly.
- Integrated Screen Recording & Mockups: Record interactions directly in the viewport for QA reports, bug reproduction, or design showcase videos.
- Lightweight Footprint: Built to load quickly alongside native Chrome DevTools without memory bloat.
The Pricing Philosophy
Screenlet is built around a simple, non-predatory model:
- Free Tier: Access every single device preset, responsive mode, and recording tool. Free exports come with a small watermark.
- Lifetime Deal ($29): If you need clean, unbranded exports for client handoffs, presentations, or portfolio demos, you can remove the watermark permanently for a one-time $29 fee. No monthly subscriptions, no recurring "software rent."
