Site Powered By has a very straightforward positioning: it helps users discover the tech stack behind any website. Based on the page copy, it can look up the plugins, libraries, third-party services, and other resources used by a website, placing it in the website fingerprinting and technology intelligence category of developer tools. The page provides a search entry point and highlights the phrase “Find what tech stack a website uses”.
Based on the extracted page content, the core function is to enter a website and search for its tech stack, covering items such as plugins, libraries, third party services, and other resources. This can be useful for developers conducting competitor research, identifying frontend libraries, spotting third-party SaaS tools, or analyzing website dependencies. However, the page does not specify which languages, frameworks, or platforms are supported, nor does it disclose its detection rules, data sources, update frequency, accuracy, history features, or bulk lookup capabilities. There is also no information about developer ecosystem features such as an API, SDK, webhooks, browser extension, or CI/CD integrations.
The page content does not provide any information about pricing, plans, free quotas, or payment methods. The page shows “Signup closed”, which means registration is currently closed. Users may only be able to use the public search feature, or the product may be in a limited-access stage. For team users, this affects certainty around account management, bulk queries, and long-term usage.
The main advantages are its clear product goal and apparently low barrier to use, making it suitable as a lightweight tool for quickly understanding a website’s technology stack. The drawbacks are also obvious: there is very little public information, and documentation, examples, coverage details, API information, and support descriptions are missing. Closed registration further reduces its commercial usability. If it is to be used for security analysis, sales lead enrichment, or large-scale competitor monitoring, its result accuracy and stability still need to be verified.
It is better suited to developers, product managers, growth teams, or technical salespeople conducting preliminary research on a single website. Access from mainland China cannot be determined from the page content, so it is marked as unknown; payment methods are also not disclosed. If you need a more mature alternative, consider Wappalyzer, BuiltWith, or WhatRuns.
