A quote calculator on your website, working, with the math right.
Every calculator below computes a real quote — the arithmetic is checked as part of the build, because a calculator that is nearly right is worse than none.
Technical SEO is checked on every one of these — title, description, structured data, headings, alt text. It is part of the build, not an upsell.
More kinds: Landing page examples · Portfolio website examples · Booking system for a small business · No-code web scraping examples · Small business website examples · Agency website examples · Clean up an Excel spreadsheet with AI — or the whole showcase.
How every one of these was made
One sentence in, a plan for free, then the build — with the cost printed on every turn. The whole turn, explained.
Describe yours in a sentence.
The first version is free to try, and the finished code lands in a repo you own.
