About PoweredBy

PoweredBy is a 100% free website technology profiler from the team behind Keywords Everywhere.

Look up any website's technology stack, browse full lists of sites using any technology, and see how stacks change over time, with history back to April 2018. No account, no paywall, no "upgrade to see more".

The data pipeline, detection methodology, and its honest limitations are documented on the methodology page. Our crawler policy lives at /bot.

Something wrong or missing? Every page has a "report" path, or reach us via Keywords Everywhere support.
