Local-first Chrome extensions that work entirely on your device. No account. No cloud. No telemetry. Ever.
Most browser extensions send your data to remote servers, require accounts, or run analytics you never agreed to. We build differently. Every LocalExt extension stores everything in your browser's local storage and makes zero network requests during normal use. Your tabs, history, form data, and extension activity are yours alone.
Press Ctrl+Shift+Space on any page. Find any tab, bookmark, or history item in under a second. Navigate with arrow keys. No mouse needed.
