Marketing site and signup funnel
Turn visitors into trials, and know which page changes actually bring more signups.
A working demo for Brightloop, an invented business. All data is made up and nothing you enter leaves this page.
Try it
- Switch the headline under test, then read the FAQ
- Toggle annual billing and drag the seat count on the pricing page
- Start a trial, reload halfway through and pick up where you left off
- Open the funnel analytics and compare the last 7 and 28 days
Under the hood
- Prices are integer cents, so the annual saving is exact to the cent
- The headline test uses a two-proportion z-test and will not call a winner before the sample is large enough
- Funnel traffic comes from a seeded random source, so every visitor sees the same figures
Built with React, TypeScript, Zod, Vitest.
The same skill in production work
- The home page scores 100 in every Lighthouse category on mobile, and a reload is answered by the site's own service worker without waiting on the network.
- Measured in early October 2026, every change to this site passed its checks in about five minutes, browser tests included, and a release took a median of 80 seconds.
