Best Form Builder With Conditional Logic: 8 Tools Compared (2026)

A form with conditional logic changes as people answer it. A visitor who picks "Just browsing" skips the budget questions. A visitor who picks "Ready to buy" sees the booking step. Each person gets a shorter form, and you get cleaner answers.

This post is for small teams picking a form builder with conditional logic this week. Look at how far the logic goes. Can it skip whole steps? Can it run math on answers? Can it pass hidden values like UTM tags into the rules? And can you use it on the free plan before you pay?

How we picked

• Depth of logic. Rules that show or hide questions, plus jumps that skip whole pages.
• Logic on the free plan. You should be able to test real rules before you spend money.
• Calculations. Scores and totals built from answers.
• What happens after the form. Where the answer goes once the logic has done its job.
• Fair pricing. Clear plans with caps you can live with.

The quick comparison

1. Claritia

Claritia is a forms and meetings tool for small teams, with workflows that follow up. Its forms come with conditional logic and step skips on the free plan, plus calculations and formulas. When the logic decides a visitor is a fit, the same form can book them into a meeting with the right person.

Best for: Teams that want the logic to end in a booked meeting.

What stands out:

• Conditional logic, step skips, calculations and formulas are all on the free plan.
• Hidden fields capture UTM tags and where the visitor came from, and the form can pre-fill from the link.
• On Pro, you can route by any answer to a meeting and a person, with a routing log.
• Tia, the AI form builder, builds a form from a plain sentence, so you start with questions in place.

Where it falls short:

• Claritia is a newer tool, so its app marketplace and community are smaller than the big names.
• Zapier and Make apps are on the way and are yet to be listed.

Pricing: Free is $0, Starter is $15 a seat a month ($12 billed yearly), Pro is $39 ($31) and Business is $79 ($63). Teammates who only build forms or read answers are free.

Questions

What is conditional logic in a form?

Conditional logic is a set of rules that change the form based on answers. A rule can show a question, hide it, skip a page or pick the ending. People only see what applies to them.

Which form builders have conditional logic on the free plan?

Claritia, Fillout, Jotform, Tally and Paperform all include conditional logic on their free plans. Typeform includes it from its Basic plan. Check each plan's caps on submissions before you commit.

Does conditional logic make forms shorter?

Yes. Each person only sees the questions that fit their answers. A shorter path means fewer people give up halfway.

Can conditional logic do math?

Many builders pair logic with calculations. Claritia and Tally both include calculations on the free plan, so you can score answers and use the result in your rules.

Can a form route people based on their answers?

Yes. In Claritia, Pro plans route by any answer to a meeting and a person. A qualified lead can book with the right teammate before leaving the page.
