What's on it
- Service and regional pages generated from one content file, each with its own local copy.
- Free tools for business owners: a website check, an accessibility check, a cookie check and a Google review link with a printable QR code.
- A quote calculator that businesses embed on their own site, and Website-APK, a monitoring service with weekly reports, uptime checks and certificate alerts.
- Research on how findable local businesses are online, published as anonymous totals only.
How it's built
- Plain Python with the standard library wherever possible, so it runs on the server's stock Python 3.8.
- The checkers fetch other people's websites, so every request is limited to public addresses, the resolved IP is pinned and each redirect is checked again.
- A per-request Content-Security-Policy nonce, no inline styles and self-hosted fonts. Every page is held to a score of 100 on the site's own checks.
Open source
The QR encoder and the three checkers are public under the MIT licence: tinyqr, website-check, toegankelijkheid-check, cookie-check and google-reviewlink.
