The web-assets category ships the supporting files every website and web app carries, the ones you rarely author by hand but constantly need to test against. The favicon set has a multi-resolution .ico, a scalable SVG favicon, and an apple-touch-icon, plus Windows cursor (.cur) samples with real hotspots. The PWA set is a complete web app manifest with a full icon spread (192, 512, and a maskable variant), a cache-first service worker, and a browserconfig.xml tile definition. Social preview cards are rendered at the exact Open Graph (1200×630) and Twitter summary (1200×600) sizes. The crawler set covers robots.txt, an XML sitemap, humans.txt, and ads.txt, and the .well-known set has an RFC 9116 security.txt, an Apple app-site-association file, and an Android assetlinks.json. There's also an SVG symbol sprite paired with its PNG twin. Every file is a realistic, standards-compliant sample against fictional example.com data, for testing crawlers, PWA installers and manifest validators, favicon and icon pipelines, service-worker registration, link-preview generators, and .well-known parsers.

Results start with a representative from each related test family. Use a card’s variant menu or the filters below to reach a specific format, profile, or failure case; every sample retains its own detail page and download.
Favicons (multi-resolution .ico, SVG, apple-touch-icon, Windows .cur), a full PWA set (web app manifest, 192/512/maskable icons, a cache-first service worker, browserconfig.xml), social preview cards at exact Open Graph (1200×630) and Twitter (1200×600) sizes, crawler files (robots.txt, XML sitemap, humans.txt, ads.txt), and .well-known files.
An RFC 9116 security.txt, an Apple app-site-association file, and an Android assetlinks.json, realistic, standards-compliant samples against fictional example.com data.
They're samples for testing crawlers, PWA installers and manifest validators, favicon pipelines, service-worker registration, link-preview generators, and .well-known parsers, point your tooling at them rather than deploying them as-is.
Start with one example from each use-case group, then continue through its other test families. Choose a use case, search, or filter to find a specific profile; a card’s variant menu contains its related samples.

Build Output
A minified stylesheet closing with the CSS form of the annotation, `/*# sourceMappingURL= */` - the comment syntax differs from JavaScript's and is a common reason a CSS map is silently ignored. For testing stylesheet so
Config
Sample App .env: small deterministic fixture for parsers and the in-browser editor.
Crawlers
An IAB ads.txt listing authorised digital sellers with account IDs and relationships (sample data), for testing ads.txt parsers and ad-fraud tooling.
Cursors
A 32×32 Windows arrow cursor with its hotspot at the top-left tip (0,0), for testing .cur parsers, CSS custom cursors, and ICO/CUR converters.
Favicons
A 180×180 opaque PNG apple-touch-icon (iOS rounds the corners itself), for testing home-screen icon extraction and Apple touch-icon handling.
Feeds
The same four articles as Atom 1.0: tag: ids identical to the RSS twin, RFC 3339 published and updated timestamps, escaped HTML content, and both alternate and self links. For diffing an RSS-to-Atom converter against a k
Indexing
The baseline every canonical audit should pass: one self-referential canonical, an indexable robots meta, matching hreflang self-reference and an og:url that agrees with all of them. For use as the comparison reference a
Pwa
A browserconfig.xml defining Windows Start-menu tile logos and colour, for testing MS tile configuration parsers and XML handling.
Social
A single @graph holding four nodes wired together by @id rather than by nesting - the shape most CMS plugins emit - including a SearchAction, a breadcrumb whose last item has no URL, and one reference to a product node t
Sprites
A 320×64 PNG icon sprite (five 64×64 cells): the raster twin of the SVG sprite, for testing background-position sprite techniques and sprite slicers.
Well Known
ads.txt: Wave G SAMPLE for crawler and .well-known tooling.
Config
Sample Dockerfile: small deterministic fixture for parsers and the in-browser editor.
Crawlers
SAMPLE crawler/policy text file (ads-txt-sample) for bot and ads.txt parsers.
Cursors
A 32×32 Windows crosshair cursor with its hotspot at the centre (16,16), for testing cursor hotspot handling and .cur decoding.
Feeds
Sample OPML Subscriptions: small deterministic fixture for parsers and the in-browser editor.
Indexing
The English member of a correct three-locale hreflang cluster: it lists itself, both translations and the x-default, and its canonical agrees. Ships with the German page so reciprocity can be verified across real files.
Pwa
192×192 PWA icon SAMPLE for manifest icon pipelines.
Social
schema.org JSON-LD SAMPLE (breadcrumb) for SEO/structured-data validators.
The use-case group filter replaces the long list of category sections.
