Unlimited Tests, Zero Hidden Fees

Chris Edington has led A/B tests for years across e-commerce, SaaS, and content sites. While existing platforms were powerful, their per-visitor pricing penalized successful campaigns and complicated budgets. He envisioned a platform that charges per project rather than visitor traffic, so teams can run unlimited tests on unlimited visitors without unexpected overage fees. This approach unbundles growth from cost, ensuring testing remains accessible and predictable. Otter A/B was built to focus on learning what works: its all-in-one suite combines a visual editor, analytics integration, and revenue tracking to empower teams to iterate quickly without usage meters or surprise invoices.

What “Radar” means for this product

Learn more about AppSumo deals

Radar is home to early-stage products looking to gain traction. Here’s the lowdown of what these deals are and aren’t.

Where it is in its life

Radar products are at the start of their journey. They're fresh on the scene and building a customer base.

How we vouch for it

We've verified the basics and reviewed the listing for safety. Success isn't guaranteed — we haven't fully vetted every claim, feature, or result.

Code & security review

All AI skills are reviewed for security purposes. We do not review software code — partner owns security and what ships.

Refund policy

60-day refund on most deals. AI skills are non-refundable once redeemed.

Pricing

Prices are set by the founder. Simple as that.

Where you'll see it

The Radar section of our site exclusively. These products are in early discovery and not quite ready for the AppSumo limelight yet.

Radar is a discovery engine — because we aren’t vetting these products, our We Got Your Back guarantee doesn’t apply. Should these products show traction, our team will work with theirs to get them ready for the main stage (and protected).
