What 1Price is
1Price is a price A/B testing tool for SaaS that focuses on revenue: its results show conversion, paid conversion, MRR and lifetime value per offering. You connect Stripe, import your products, and add a script tag that exposes the prices to your page. It also offers pricing experts and a done-for-you setup.

When 1Price fits better

- You’d rather have pricing experts set things up for you.
- Your site is on Framer, Webflow or WordPress and you don’t use a coding agent.
- You have under 5,000 visitors a month and want the lowest monthly price.
When PricingFast fits better
- You build with Claude Code, Cursor or Codex and want the agent to do the install, on a branch you review.
- You want to see the stop rule up front: 95% confidence, 30 sales, revenue per visitor.
- Your checkout can’t depend on a third party: PricingFast falls back to your prices within 1.5 seconds.
- You want to rehearse both prices on localhost before any visitor sees them.

Questions
Is 1Price or PricingFast cheaper?
1Price starts at $39 a month for up to 5,000 monthly visitors, with higher tiers priced on request. PricingFast is $79 a month or $790 a year with no visitor limit, and the first test is free up to 10,000 visitors.
Do both tools work with Stripe?
Yes. Both connect to Stripe. With 1Price you create test prices in the Stripe Dashboard and import them; PricingFast creates them for you.
Which one picks the winner by revenue?
Both report revenue. PricingFast calls a winner on revenue per visitor once one price is ahead with 95% confidence and at least 30 sales. 1Price's documentation shows conversion, MRR and LTV tables but doesn't document its significance rule.
