Web Technology Adoption Report: 129M Domains

Data report by the SearchWebCode team · August 2026 index build · Updated August 7, 2026

This report measures technology footprints in the HTML, CSS, and JavaScript delivered by the homepages of roughly 129 million unique domains. It is a source-code census: each count is the number of indexed domains whose stored homepage contains the listed substring, verified against the source itself.

The results describe observable adoption, not vendor customers, active paid accounts, or market share among a hand-picked category. Technologies overlap heavily-a WordPress site can also ship jQuery, Google Fonts, WooCommerce, and several analytics tags-so rows must not be added together. The share column uses approximately 127,800,000 indexed domains as its denominator.

Adoption across the August 2026 index

What the leading footprints say

Older, broadly embedded front-end building blocks remain the most visible layer of the web. The jQuery filename footprint leads at 34,960,796 domains (27.37%). Google Fonts follows at 30,700,679 (24.03%), and WordPress at 24,899,751 (19.49%). Bootstrap reaches 17,915,175 (14.02%), while Font Awesome reaches 17,288,215 (13.53%).

These rows are deliberately footprint-specific. A site that bundles jQuery under another filename will not match jquery.min.js; a site that self-hosts fonts will not match fonts.googleapis.com; and a customized WordPress deployment can hide wp-content. The measured shares are therefore shares of indexed homepages exposing each chosen signal, not upper-bound estimates of all possible installations.

Framework visibility is not framework market share

The react-dom signal appears on 952,016 domains (0.75%), ahead of the framework-specific __NEXT_DATA__ marker for Next.js at 600,211 (0.47%). That gap should not be read as a complete React-versus-Next.js market calculation. Production bundling can erase a readable react-dom string, while __NEXT_DATA__ is a narrow marker emitted by a particular rendering path. The counts are reproducible precisely because they stay attached to their stated substrings.

Measurement, tagging, and security code

Google Analytics 4 is visible on 9,614,187 domains (7.53%), ahead of Google Tag Manager at 7,391,424 (5.79%). The two populations overlap but are not interchangeable: GTM can deploy many products, and GA4 can be installed without the GTM container footprint.

Cloudflare Insights appears on 5,814,915 domains (4.55%). That row measures the browser-side Insights beacon, not every domain proxied by Cloudflare. reCAPTCHA appears on 5,060,663 (3.96%), and Meta Pixel on 2,986,269 (2.34%). As with every row, presence shows that the homepage source exposes the footprint; it does not prove the tag fired successfully or that a paid account is active.

Commerce and marketing stacks

The WooCommerce plugin path is present on 5,031,078 domains (3.94%), while Shopify's CDN footprint appears on 1,975,674 (1.55%). These are not directly comparable platform market shares: WooCommerce exposes a plugin directory on WordPress, while Shopify exposes a hosted asset domain. They are two concrete source signals measured by the same index.

Down the commerce and marketing stack, Stripe.js v3 appears on 487,552 domains (0.38%), Klaviyo on 387,387 (0.30%), and HubSpot on 287,468 (0.23%). A small homepage-source share can still describe a substantial specialist ecosystem, and integrations limited to checkout, account, or post-consent routes will not necessarily be visible in this homepage census.

Methodology

SearchWebCode built this dataset in August 2026 from a trigram index over approximately 129 million homepages, with one homepage per unique domain. For each technology, the engine used the exact substring shown in the table to retrieve candidates, then performed a verified substring match against the stored source before counting the domain. The index is refreshed monthly.

The denominator for each displayed share is approximately 127,800,000, so shares are rounded to two decimal places and should be cited as approximate. Rows overlap. The method can miss code loaded only after JavaScript execution, consent, authentication, or navigation to a deeper page; it can also count a dormant or quoted footprint that remains in HTML. The technology pages document the practical false-positive boundary for each signal, and the full matched source is available for result-level verification.

How to cite and reuse this report

Cite the technology, exact footprint, verified domain count, approximate share, index scope, and build month together. For example: “The August 2026 SearchWebCode homepage index found 24,899,751 domains (19.49% of approximately 129 million) containing wp-content.” Keeping the footprint in the sentence makes the claim reproducible and prevents a source-code observation from being inflated into an unsupported total-market estimate.

The full table is available as a dated CSV snapshot, web-technology-adoption-2026-08.csv, for spreadsheets, notebooks, and republication. Reuse is welcome with attribution: cite "SearchWebCode, August 2026 index" and link this page so readers can verify any number against the live search.

Data quality & editorial policy

Every count we publish is verified against stored page source: an exact match count where the engine can prove one, otherwise an estimate scaled from a verified sample of real pages, never a survey extrapolation. The exact footprint appears next to each number so any claim can be re-run as a search and checked result by result. Reports are tied to a dated index build; when a new build changes the numbers, we update the page and move the modified date above. Corrections are made in place.
