The Chrome Web Store rounds user counts down to the leading digit, so the user line moves in steps. The ratings count is exact and is the better signal of real adoption.

About interpolate

Interpolate is designed to improve your developer experience by empowering you, and your team, to develop/test features and fixes faster and easier. You can add headers to outbound requests, declaratively redirect requests, create mock responses to requests with HTML or JSON conditionally based on URL and content of a request, execute commonly used javascript snippets (user scripts) in the browser, and even automatically place tabs in specified tab groups when links are opened in a new tab. You can create your first interpolation by clicking "Create interpolation". Then select an interpolation type: redirect requests, add headers, mock API, or create user scripts FYI: There will be a banner informing you that this extension is debugging in the browser. This is because it leverages the Chrome DevTools Protocol. This is expected. Interpolate is built with transparency in mind. Other extensions often hack around this, but we wanted users to know exactly how Interpolate accomplishes its core functionalities (by debugging in your browser). No "AI" or LLM was leveraged used in the development of this extension. This is developed by humans for humans.
