Extenshi

Extenshi gives Claude live data on browser extensions from the Chrome Web Store, Firefox Add-ons and Microsoft Edge Add-ons.

For people who use extensions

• Ask whether an extension is safe: permissions it requests, security findings, how risky its access is, and what its reviews say.
• Paste a list of the extensions you have installed and get a risk summary for all of them at once.
• Find safer or better-rated alternatives to an extension you are unsure about.

For people who build extensions

• Research a niche: competitors, user counts, ratings, what reviewers complain about.
• Plan and build an extension with a step-by-step development guide, templates, manifest import and localization, icon and welcome-page workflows.
• Keep a hosted privacy policy and store listing in sync with your project, and set up payments with Extenshi Pay.

Try asking Claude

• "Is the extension 'X' safe to install?"
• "Here are my extensions — which ones have risky permissions?"
• "Find a well-rated alternative to X that requests fewer permissions."
• "What do users complain about in the top tab-manager extensions?"
• "Help me build a Chrome extension that does Y, from idea to store release."
