What’s actually slowing this PC down?

To see what technologies a website uses, enter its domain in BuiltWith’s lookup. The service reports technologies it detects from signals in publicly visible website code and infrastructure. Treat the result as a useful profile—not a complete or guaranteed-accurate blueprint of how the site works.
What BuiltWith shows
BuiltWith is a website-profiling service for identifying technologies associated with a domain. Its profiles can cover categories such as content management systems, eCommerce platforms, analytics, web frameworks, advertising technology, CDNs, servers, web standards, and AI-related technologies. BuiltWith describes its broader business as including lead generation, competitive analysis, and business intelligence. See its About Us page for the company’s description of its services.
A profile may show that BuiltWith detected evidence of a particular technology, but it does not establish that the entire site is built with that technology. Websites commonly combine multiple products and services, and a detected signature may not reflect what is currently active.
How to look up a website
- Open BuiltWith and enter the domain you want to check in its lookup.
- Submit the domain and review the technology profile returned for that site.
- Use the results as leads for further investigation. If a technology matters to a technical, security, or sales decision, verify it independently rather than relying on the profile alone.
BuiltWith says individual website lookups are free. Its FAQ explains that it looks for technology “signals” given off by websites. A reported result is therefore evidence from those signals, not confirmation of every component in the site’s implementation. The BuiltWith FAQ describes the lookup and its other options.

- Read Before You Buy — No Video Output: These adapters support charging and USB 2.0 data transfer, but cannot transmit video signals. Except for standard USB webcams (which use USB data only), they are not compatible with HDMI/DisplayPort cables, video-capable USB-C hubs, or docking stations with video output.

- Compact & Travel-Friendly: The ultra-compact design allows the adapter to stay plugged into your device without blocking adjacent ports or adding bulk, reducing wear and tear on your original USB ports.
- 12-Month Warranty: Backed by a 12-month manufacturer warranty for peace of mind. Designed to meet strict quality control standards for reliable everyday performance.
Why a detection may be wrong or out of date
BuiltWith’s Terms of Use say technology detections rely on signature evidence and may not be fully accurate. The terms identify several reasons a result can mislead:
- Unused code: a site may contain a technology signature even if the associated technology is no longer actively used.
- Lingering signatures: traces can remain after a technology has been removed.
- Indexing delays: the profile may not immediately reflect a site change.
BuiltWith provides the service as-is and does not warrant that detections are complete or accurate. Its official terms do not give an independent accuracy percentage, so a result should not be treated as proof.

When the free lookup is enough—and when to consider more
A single manual lookup is suited to a quick check. For broader or recurring research, BuiltWith advertises paid reports, lead lists, filtering, exports, alerts, historical information, integrations, and trend data. Its Plans & Pricing page lists current plan details; features and prices can change, so check the live page and confirm the billing interval, minimum term, and cancellation terms before subscribing.
BuiltWith’s FAQ says monthly plans have a one-month minimum and yearly plans a one-year minimum; cancellation does not immediately end access already paid for. For historical coverage, BuiltWith says its advanced features include technology-report history extending beyond 16 years and trends for core technologies as far back as 2009. These are vendor-described coverage claims, and the available history can vary by technology.
