Questions & Answers

As answered by people managing Project Euler and DomainCapybara.

What makes your product unique?

DomainCapybara's answer:

Most tools rank domains by the first-year promo price, which hides the renewal jump that actually costs you money. DomainCapybara ranks registrars by their 3-year total, first year plus renewals, so the cheapest-looking option and the actually-cheapest option stop getting confused. It is 100% free and needs no signup. Prices get updated daily and the UI is modern and clean.

Why should a person choose your product over its competitors?

DomainCapybara's answer:

It is honest about the numbers. Renewals sit front and center and rankings are not affected by affiliate links. No account, no ads, no fake urgency.

How would you describe the primary audience of your product?

DomainCapybara's answer:

People buying or moving a domain who want the cheapest real long-term price. Indie founders, developers, side-project builders, and small businesses. Especially anyone who once grabbed a cheap first year and then got hit by a painful renewal.

What's the story behind your product?

DomainCapybara's answer:

It started with a GoDaddy renewal. The first year was cheap, then the renewal came in several times higher. The founder went looking for a tool to compare registrars properly and mostly found messy tables, prices that were often wrong, and pages buried in ads. So he built the alternative he wanted: accurate prices updated daily, renewals shown up front, and a clean modern interface.

Which are the primary technologies used for building your product?

DomainCapybara's answer:

Next.js and React with Tailwind CSS, hosted on Vercel. The daily pricing pipeline is backed by Upstash Redis and Neon Postgres.
