Puffin.io is perfect for any type of website A/B testing You can A/B test your landing pages, lead forms, shopping cart funnel, on-boarding funnel, buttons, headlines, hero images, page redesigns and more. Puffin.io is inspired by making an A/B testing tool fast, simple, affordable. We like to challenge ourselves by making things simple. Attending training to launch an A/B test, isn’t simple. We get excited by less. Not more. And we know you might be looking for a Swiss-army knife. But we are far from that, we are a samurai sword. A/B testing. Simple. Fast. Inexpensive.
