SearchWebCode vs BuiltWith

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.

Start with the evidence you need: a technology profile, a dated relationship between sites or an exact source match. BuiltWith and SearchWebCode offer different ways to investigate those questions.

What is BuiltWith?

BuiltWith provides current and historical technology profiles and APIs. It also documents a Relationships API that connects domains through shared identifiers, including analytics IDs and IP addresses, with first-seen, last-seen and overlap fields. This capability extends beyond technology-category lists.

BuiltWith also offers a Keyword Search API for website keyword lookups. These APIs should be evaluated on their own inputs and results; they are not interchangeable with a regex over captured HTML. Documentation checked October 14, 2026.

What SearchWebCode is

SearchWebCode searches stored homepage HTML by text, boolean expression or regex. You can query a particular asset path or tracking ID without first selecting a named technology. Returned source matches open with highlighted occurrences and surrounding code.

At a glance

Source queries and relationship searches

To find a shared analytics ID, SearchWebCode checks the chosen string in stored homepage source. BuiltWith can start from a known domain and return other domains associated with its recorded identifiers. Its relationship records include observation dates and whether the identifiers overlapped. A shared ID can come from an agency or copied template, so neither result establishes common ownership by itself.

Seeing the evidence

Use SearchWebCode when you need to inspect the captured HTML around a path, version or ID. Use BuiltWith’s profiles and relationship records when their structured detections and history answer the question. A captured reference or detector label does not confirm current execution; check the site separately when that distinction matters.

Pricing and export allowances

Research is $15/month or $150/year, with 400 search credits and 50,000 export rows per month. Pro is $80/month or $720/year, with 3,000 search credits and 500,000 export rows per month. SearchWebCode also offers prepaid search credits at 5¢, with reviewed quotes for bulk-export overages. Check current pricing and request limits. BuiltWith’s subscriptions and API products have their own terms; see its published plans before comparing costs.

When BuiltWith fits the task

• You need structured technology profiles or historical detections.
• You want relationship records with observation dates.
• You use its technology lists, keyword lookups or enrichment products.

When SearchWebCode fits the task

• You have a specific source string or regex to investigate.
• You need the captured HTML around each match.
• You want to export matching hostnames into your own workflow.

Historical data and freshness

BuiltWith’s API documentation describes current and historical profiles and dated relationship observations. SearchWebCode searches its latest quarterly homepage snapshot; it does not reconstruct each site’s technology history. Record the provider’s observation dates, query and count type when comparing results.

A worked example

Copy an analytics ID from the source of a known site. Search it on SearchWebCode and inspect the stored matches. Query that site through BuiltWith’s Relationships API to compare its recorded identifiers and observation dates. Investigate copied tags and shared agencies before attributing the sites to one owner.
