In-depth safety analysis
Wappalyzer requests broad host permissions for all websites and several API permissions including cookies, storage, tabs, and webRequest. This allows it to read page content and network requests on any site you visit, which is necessary for its core function of detecting the technologies a website uses. The permission scope is typical for a technology profiler, as it must inspect page elements, scripts, and headers to identify frameworks, analytics tools, and other software.
General browser extensions that can read all website content carry inherent privacy considerations. A careful user should be aware that any extension with such broad access could technically see sensitive information displayed on pages, such as account details or private messages, even if its stated purpose is benign. It is wise to review the developer's privacy policy and understand what data is collected and how it is handled.
Based on the fact sheet, this extension shows strong maintenance and ownership, with a recent update and a high community reputation score. The weakest dimension is permissions and access, which reflects the extensive host permissions required for its functionality rather than any specific misuse. The developer declares that website content is collected and that data is not sold or used for unrelated purposes.
AI-assisted analysis of the documented signals above (permissions, store data, privacy practices) — explains what they mean and the risks typical for this category. Not a hands-on test.
