Our verdict on WhatRuns
WhatRuns is a free browser extension for identifying the technologies used by websites. It is suited to competitor analysis, sales intelligence, website profiling, and general technology research. Available on the web and through its Chrome extension, WhatRuns can inspect a website’s stack with one click and does not require sign-up according to its official website. Its focus is website-level detection rather than company-level intelligence.
The product covers a broad set of web technologies in a focused workflow. It identifies frameworks, CMS platforms, WordPress plugins, themes, fonts, analytics tools, ad networks, and developer tools. Users can also follow websites and receive notifications when technologies are added or removed, while technology-based website lists support research across groups of sites. This makes WhatRuns a practical fit for quickly profiling a site or tracking changes over time through notifications.
WhatRuns is most appropriate for buyers who need free, browser-based technology discovery without a paid plan. Its limits matter for more advanced technographic programs: the product does not provide company profiles, API access, exports, or historical technology data. Teams that need to connect detection data to internal systems, analyze past technology states, or enrich account-level records should choose a broader product instead. For lightweight website research and ongoing change notifications, WhatRuns keeps the scope clear and accessible.
