Hey @dzheey! The Windows app sitting around ~450 MB is actually the expected size, so nothing odd is going on there. Different folks have different thresholds for what feels “heavy,” but for 1Password that footprint is normal.

If you’re seeing anything larger than that or something seems out of the ordinary on your machine, happy to take a look with you.

It's because rather than being a "native" application, 1Password is using the Electron framework which automatically adds 250 - 300MB to each application because it bundles Chromium (the open-source browser engine and node.js) inside every application. There's also the ~140MB "index.node" add-on (binary module) which enables node.js to call functions written in other languages.

Lots of cross-platform applications use Electron because it is easier for the developers, even though it results in a worse experience for users due to bloated application sizes and non-native look, feel and functionality compared to native apps.
