ClaudeCommunityby Maksim Kosterin

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." Sign in with your Extenshi account. Getting started is free: every account includes a free allowance of catalog reads, and the documentation search and development guide are always free. Hosted privacy policies and some project features require a Pro plan. Extenshi never asks for your browser data or passwords. Tools that change anything in your account are clearly marked, and payment setup, KYC and agreements stay in your browser.
