Boosts
Make the web yours
Small changes to the sites you use every day: hide Shorts, widen GitHub, read Hacker News at night. Open one in Cra, see what it changes, and keep it.

The gallery
Look only, every time
A Boost from the gallery or from a link changes how a site looks. It can’t do anything else.
- No code runs
- Gallery Boosts are colours, fonts, text size, hidden parts and CSS. A shared Boost’s JavaScript never leaves the Mac it was made on.
- Nothing loads
- CSS that would fetch from the web, like url() or @import, is refused. A Boost can’t send what you type anywhere.
- Cra asks first
- Open in Cra shows what the Boost changes and on which site. Nothing is added until you say Add Boost.
- A person reads each one
- Every gallery Boost is a pull request to Cra’s open-source repo, tried on its site before it’s listed.
Made one worth sharing?

Share Boost…
