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

说明与用途

ExtensionRelease Guard 让开发者在上传前本地检查 Chrome 扩展的 ZIP 包，发现清单、引用、语言包和图标等错误，减少返工。

问题

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

结果

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

工作流

• 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

证据

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

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

来源

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.
