Catch Chrome extension packaging mistakes before you upload (free, local tool)

Описание и применение

Инструмент ExtensionRelease Guard позволяет разработчикам проверять ZIP‑архивы расширений Chrome на наличие ошибок до загрузки, выявляя проблемы с манифестом, ссылками, локалями и иконками.

Задача

Extension developers often discover packaging errors only after uploading, causing delays and rework.

Результат

The tool identifies ZIP structure problems, manifest validity, missing references, locale issues, and icon format mismatches, providing actionable notes and a readiness summary.

Рабочий процесс

• Create ZIP of extension folder
• Open ExtensionRelease Guard
• Drop ZIP onto the app window
• Review findings and notes
• Fix reported issues in source
• Re‑zip and re‑upload
• Optionally export report or compare JSON reports

Доказательства

I wanted to catch those mistakes before uploading, without sending my extension anywhere.

Источник

Each finding comes with a short note on why it matters and what to do, and the app gives a readiness summary.

Источник

It reads the archive without extracting or running anything, so it can't judge what your code does, and a clean result does not mean your extension is safe or will pass Chrome Web Store review.
