What determines the cost of a Chrome extension?
There is no single universal price. The work depends on what the extension needs to do, how much browser logic is required, and how polished the interface needs to be.

Interface and branding
Custom design, responsive popup behavior, icons and a polished product experience all add development work.
03
Browser integration
Extensions that interact with websites, tabs, storage, authentication or browser APIs require more technical logic than a basic popup.
