What you get
Made for the browsers you already use
Undo built in
Removals and disables are written as browser policy, not as edits to your profile, so one command puts every one of them back exactly as it was.
$ npx @extenshi/guard undo
Look before you share
npx @extenshi/guard list prints the local inventory with no account and no network calls at all.
Reasons in plain language
Each flag says what the extension can reach and why that stood out — no jargon, no scores to decode.
You choose, item by item
Remove, disable or leave alone. The checklist is a suggestion, never a decision.
Nothing to install
It runs with npx on macOS, Windows and Linux. No app, no daemon, and no browser extension of its own.
Privacy
What leaves your computer, and what does not
Guard asks before it sends anything, and it prints the full field list first. This is that list.
- Asked once, in writing
The first check shows the notice and waits for a yes. Declining stops there — the local inventory still works.
- Revocable at any time
Your saved inventory lives in your account. Review it or delete it from your dojo whenever you want.
- Assessed by a published method
How an extension earns its risk score is written up in full. Read the methodology →
Sent, after you agree
Per extension, enough to identify the build:
- store id
- store
- version
- enabled
- install origin
- install time
- update URL
Never sent
Not read, not uploaded, not at any point:
- extension names
- descriptions
- local file paths
- browsing history
- bookmarks
- passwords
- page content

FAQ
Questions people ask first
- Do I need to install anything?
- No. It runs through npx, which comes with Node.js. There is no app to install and no extension to add to your browser.
- Does it cost anything?
- Listing what is installed on your machine is free and works without an account. Checking that list against the catalog is what costs, and every account includes one free analysis. Beyond that you buy prepaid packs — no subscription, and the credits never expire.
- What is sent to extenshi.io?
- Only the extension id, version, browser and enabled state of each installed extension, and only after you agree. Browsing history, bookmarks, passwords and page content are never read.
- Which browsers are supported?
- Chrome, Edge, Brave, Vivaldi, Opera, Arc, Yandex, Chromium and Firefox, including separate profiles within each browser.
- Can I undo a cleanup?
- Yes. Changes are applied through the browser’s own policy settings, and the undo command reverts everything guard applied.
- Will it delete an extension I still use?
- Nothing is changed until you tick it in the checklist and confirm. The suggestions are a starting point you edit before anything is applied.
