Questions & Answers

As answered by people managing PricingFast.st and Diffee.

Which are the primary technologies used for building your product?

PricingFast.st's answer

Next.js, Supabase (Postgres), Stripe Connect and Checkout, Vercel, an MCP server, PostHog.

Who are some of the biggest customers of your product?

PricingFast.st's answer

None yet: PricingFast launched recently and has no paying customers to name.

What makes your product unique?

PricingFast.st's answer

It A/B tests the price itself on Stripe, not a page design. Each visitor sees one price and pays exactly that price at Stripe Checkout. The winner is picked by revenue per visitor, not by conversion rate. Your coding agent installs it over MCP, and nothing goes live until you press Launch.

Why should a person choose your product over its competitors?

PricingFast.st's answer

Generic A/B tools know nothing about revenue. Pricing tools for mobile apps (RevenueCat, Superwall) don't work for web SaaS. PricingFast is built for SaaS on Stripe. Setup takes one sentence ("+20% for half of new visitors"). You check both prices on localhost before going live. Once a price wins, you apply it in one click, and people already subscribed keep their current price. The first test is free.

How would you describe the primary audience of your product?

PricingFast.st's answer

Indie founders and small SaaS teams who bill through Stripe, get steady traffic on their pricing page, and suspect their price is too low.

What's the story behind your product?

PricingFast.st's answer

Changing a price is stressful because you only get one try. If sales drop afterwards, you can't tell whether the price caused it or it was just a slow month. Mobile apps solve this by showing two prices at the same time, but web SaaS on Stripe had no simple way to do it. So I built one.
