STOP DOING IT THE HARD WAY

Extension development has been painful for too long. We fixed it.

The Struggle

Manifest Migration

“Hours spent reading confusing documentation, fixing service worker errors, and worrying about store rejection.”

The Fix

Instant V2 to V3 conversion with automated code analysis and actionable warnings.

The Struggle

Localization

“Manually copy-pasting strings into Google Translate for 50+ languages. Inconsistent formats and broken JSON.”

The Fix

Automated translation for _locales. Support for 54 languages in a single click.

The Struggle

Store Assets

“Struggling with Photoshop to get exact 128x128, 48x48 icon sizes. Screenshots look unprofessional.”

The Fix

Auto-generate all required icon sizes and create stunning, device-framed screenshots instantly.
