Browser Userscript Platform Replacing Extensions with Lightweight Scripts
C6/10April 25, 2026
WhatA managed platform for discovering, sharing, and running small per-site JavaScript snippets (userscripts) as a lightweight replacement for heavy browser extensions.
SignalA Brave user described replacing most of their extensions with small site-specific scripts using Brave Scriptlets, and the enthusiasm suggests many power users would prefer lightweight, composable scripts over bloated extensions — especially as MV3 restricts what extensions can do.
