Perch

v0.18.4

Websites that ask to record your screen only ever get the single tab that asked — labelled Entire screen, reporting itself as a monitor. The picker opens exactly as it always does, and the site cannot tell the difference.

Mirror: Page-only crop, click and scroll forwarding

Perch's settings window, showing toggles for going fullscreen while a site is sharing, cropping the mirror to the page, and forwarding clicks and scrolls. — Perch · Settings

Perch's Mirror settings: go fullscreen while a site is sharing, and show only the page in the mirror — both on, with the explanation of what each one crops.

extensions

Four small ones, in the browser

Anti-Blur

v1.0.1

Stops sites pausing, dimming or watching for the moment you look away. A page you switched tabs on keeps running as though you were still there.

Permissions: None at all. It declares no Chrome permissions and no host access — only a content script. There is nothing for it to ask you for.
Plans: Every one, Supporter included

Sodium

v3.4

Raw speed. It pre-fetches what you are about to open and blocks trackers at the network layer, before the request is made rather than after the script has run.

Permissions: declarativeNetRequest — Chrome applies the rules itself, so the extension never sees your traffic
Plans: Every one, Supporter included

Argon

v0.1.0

Stops sites recognising you between visits without a cookie. It shows you which ones read your graphics card, your fonts, your screen and your hardware to fingerprint you — and substitutes what they get.

Consistency: Canvas, WebGL and WebGPU never contradict each other. A contradiction is easier to spot than the value being hidden.
Not yet: Screen, fonts, devices and locale are report-only so far — it tells you they were read, it does not change them.
Plans: Pro and Max

Typeswap

v1.0.0

Your fonts on any website — including the ones whose Content-Security-Policy blocks every other font extension: YouTube, GitHub, X, Google Docs.

Sources: A file, a URL, a .zip, a Google Fonts stylesheet, or anything already installed on the machine
Rules: Per family: all sites, all except some, or only some. Variable fonts keep every axis, each with its own slider.
Plans: Pro and Max

The real popup, switching tabs

None of these is a separate purchase and none ever will be. The Hub holds whichever your plan covers and opens a browser with them already loaded — that browser, not the Chrome you already have open, because Chrome refuses the debugging pipe on a logged-in profile. You can load one into your own browser yourself: what the Hub downloads is a plain folder, and Chrome’s own Load unpacked takes it, on any profile. When a plan stops covering one it stays installed and keeps working; it simply stops receiving updates. How they run · See what each plan covers.
