Website Health Report

Enter a website you own and get a scored report on security headers, TLS, DNS and email authentication, performance and SEO basics. Checks are passive only, with no intrusive scanning. The report opens at a private link, a PDF copy can be emailed with your consent, and a magic-link dashboard keeps your history, rescans and comparisons.

Delete your data at any time. It is removed after 30 days. Performance scores can be missing when the free PageSpeed quota is reached.

Working demos with fictional data, built to show what's possible.

Booking and Quote System

A marketplace demo for places to stay and places to eat. Stays book nights; restaurants book a table at a time slot for a party size. Hosts manage only their own listings, and guests get PDF quotes and confirmations. The brand, Quillmoor, is fictional, with a demo banner on every page and a nightly reset.

No real payments: Stripe runs in test mode only, and payment is not set up on the demo yet. Sign in with the demo logins (opens an external site in a new tab) to book.
