SearchWebCode vs W3Techs
Provider descriptions link to public sources · current index built September 2026
SearchWebCode data: 131.2M indexed homepages, one homepage per hostname, including subdomains. The latest quarterly source snapshot is September 2026. Query dates describe checks against that stored index, not live installation checks. Data and methods.
W3Techs (World Wide Web Technology Surveys) answers "how much of the web uses this?" It reports market-share percentages and long-run adoption trends for technology categories, server-side languages, CMS, web servers, JavaScript libraries, analytics, CDNs, from a relevance-filtered website sample. SearchWebCode answers a different question, "which exact sites ship this, and can I see the code?", by searching the raw source of its index for any string or regex. One is a statistics publisher; the other is a search engine.
What is W3Techs?
W3Techs selects websites with meaningful content or functionality and excludes duplicates and redirected domains. Its methodology described a sample of over 20 million websites on October 14, 2026, with subdomains counted as part of the parent site. Its reports are updated daily. W3Techs methodology.
What SearchWebCode is
SearchWebCode returns source matches from stored homepages in its latest quarterly index. Each returned match can be opened in full captured source. Population counts can be candidate bounds, sample estimates or exact verified totals, as labelled; none is a census of currently active installations. An archived report needs its original index and query response to reproduce the same total.
At a glance
| SearchWebCode | W3Techs | |
|---|---|---|
| Category | source-code search engine | market-share survey |
| Answers | which exact sites ship this | what share of sites use this |
| Query model | any literal string or regex | a catalogue of surveyed technologies |
| Sample | the full index of homepages | relevance-filtered websites; subdomains combined |
| Per-site list + export | yes, browse and export domains | aggregate shares; limited site lists |
| Shows the matched source | yes, full page source | no, published statistics |
Shares vs the actual list
W3Techs is built to be cited: "this CMS powers N% of all websites." That aggregate, drawn from its relevance-filtered website sample, is exactly what you want for a headline or a trend line. It is not built to hand you the sites. SearchWebCode goes the other way, it starts from the list: run the footprint, get the domains that match, open any one to read the source, and export the set. If your question is "how big is this, and is it growing," W3Techs is the instrument; if it's "give me the sites and the proof," it's SearchWebCode.
Top-sites sample vs the whole index
W3Techs deliberately surveys popular sites, which keeps its percentages meaningful but means the long tail is out of scope by design. SearchWebCode searches its full homepage index rather than a ranked sample, and ranks results by popularity so recognizable sites surface first while the long tail stays reachable. The two measure different populations, W3Techs a curated head, SearchWebCode the broader index, so their numbers aren't meant to be identical, and each is explicit about what it counts.
Verifiability
A survey asks you to trust its methodology; a search lets you check. SearchWebCode labels candidate bounds, sample estimates and exact verified counts. The footprint and current query are linked, and each result opens the source that matched. Reproducing a dated report requires its archived index and query responses. For a claim you need to defend, a competitive brief, a compliance note, being able to point at the pages themselves is the difference between a statistic and evidence.
When W3Techs is the better choice
- You want a citable market-share percentage across the web.
- You're tracking a technology's adoption trend over months or years.
- A consistent top-sites sample matters more to you than the individual sites.
When SearchWebCode is the better choice
- You need the actual list of sites shipping a footprint, not a percentage.
- You need to read the full matched source to verify or investigate each result.
- You want to search arbitrary strings or regex, filter by TLD, and export the domains.
- You're doing OSINT or security work where the evidence, not the aggregate, is the point.

Frequently asked questions
Is SearchWebCode a W3Techs alternative?
W3Techs publishes technology usage shares for a relevance-filtered website sample, combining subdomains. SearchWebCode searches stored homepage documents by hostname and returns source matches with labelled counts. Choose the population and evidence that fit the question.
Does W3Techs give you the list of sites using a technology?
Mostly it publishes aggregate percentages over a top-sites sample; full site lists are limited. SearchWebCode is built around the list, run a footprint, browse the matching domains with full source, and export them.
Why don't the numbers match W3Techs?
Different populations. W3Techs filters its website sample by relevance and combines subdomains. SearchWebCode counts source fingerprints across homepage documents, one per hostname including subdomains, and labels candidate bounds, estimates and verified totals. The populations and measurement methods differ.
Can I verify SearchWebCode's counts?
Yes. Every count is a substring match with the exact footprint shown next to it, the search is one click away, and each result opens the full page source, so any figure can be re-run and checked result by result.
