Eight more, independent.

Tested 10 Nov 2026. Scores can move a little between runs.

  1. A+12 of 12 checks passed

    Mozilla Observatory by Mozilla

    Checks: The security headers that tell a browser what the page may load, run and connect to.

    How hard: A+ needs every header set and a content policy strict enough to block injected scripts. Templates and plugins that add their own scripts usually rule it out.

  2. A+

    Security Headers by Snyk

    Checks: Six key security headers, and whether any are set unsafely.

    How hard: One missing or loose header drops it to A or below.

  3. A+on every server

    SSL Server Test by Qualys SSL Labs

    Checks: The HTTPS setup: certificate, protocol versions and encryption.

    How hard: A+ needs modern encryption only, plus HSTS, which forces HTTPS on every visit. A default setup usually stops at A.

  4. 100%

    Website test by internet.nl

    Checks: Modern internet standards: IPv6, signed DNS (DNSSEC), HTTPS strength and security options.

    How hard: Run by the Dutch Internet Standards Platform. Hosting defaults often fail on old encryption. This site did too, until the settings were tightened.

  5. 0trackers found

    Blacklight by The Markup

    Checks: Ad trackers, third-party cookies, session recording, keystroke capture, and the Facebook, TikTok, X and Google ad pixels.

    How hard: Most sites carry several. Zero means nothing on the page reports to anyone.

  6. A+0.02 g of CO₂ a visit

    Website Carbon by Wholegrain Digital

    Checks: How much data a visit moves, and the energy behind it.

    How hard: Cleaner than 96% of pages it has tested. A+ means under 0.04 g. Large images, video and heavy scripts push a page down the scale.

  7. 0errors, on every page

    HTML Checker by W3C

    Checks: Whether the code follows the HTML standard, so browsers and screen readers never have to guess.

    How hard: Errors creep in easily: one stray attribute counts.

  8. 0errors

    WAVE by WebAIM

    Checks: Accessibility: missing labels, descriptions and structure.

    How hard: It also lists 9 contrast warnings. 8 are red notes it checks before they fade in, and 1 is the deliberately bad example on the home page. Lighthouse and axe pass them all.
