Which online form builder has real conditional logic?

Ten builders compared on one question: can your form change based on what people answer, without upgrading first?

The short answer: Tally if you want the full logic toolkit on a free plan, Fillout if you need hidden fields, URL parameters and calculations with 1,000 free responses a month, Jotform if each submission has to land in the right inbox, and Gravity Forms if your site runs on WordPress. Typeform still gives the nicest respondent experience, but the response caps make it expensive fast. Google Forms and Microsoft Forms work as long as your logic is "if they pick A, go to section 3" and nothing more.

Conditional logic is what lets a form react to answers: skip questions, show new ones, calculate a price or a score, and route the submission somewhere specific. Most "best form builder" lists treat it as a yes/no checkbox. It isn't. A builder can tick the box and only handle one of those four jobs. So we went through every tool on all four, plan by plan, in 2026.

Pick in one line. Solo or small team on zero budget: Tally. Forms tied to a database or CRM: Fillout. Support or HR teams triaging requests: Jotform. WordPress site: Gravity Forms. Internal approvals: Zoho Forms. Brand survey with low volume: Typeform.

The table that settles it

What each builder's logic actually does

Four kinds of logic, so you know what you're reading. Skip logic (or branching) sends people to another page or section. Show/hide makes a question appear or disappear on the same page. Calculations add up points, prices or scores. Routing decides where the submission goes: which recipient, which ending, which URL.

Every builder here does skip logic. What separates them is everything else, and which plan unlocks it. Rank follows logic quality; the score out of 5 is the tool's overall score, the same one as in our full reviews.

Best for full conditional logic on a free plan

Tally

4.3/5

Tally made an unusual call: all of its conditional logic sits on the free plan. So do calculations and the redirect at the end of the form. Its help center is blunt about it: no upgrade needed, no cap on how many conditions you add. Forms and responses are unlimited too, under a fair use policy whose threshold Tally doesn't publish.

A Tally rule can do six things: jump to a page (or the thank-you page), calculate a value, make a question required, show or hide blocks, hide the submit button to block the submission, or redirect to a URL or another Tally form. Conditions combine with AND and OR, including nested groups. That's more than most competitors offer on paid tiers.

Two gotchas straight from the docs. Jumps only fire when someone clicks "Next" or "Submit", so the rule has to live on the page where the question is, not the next one. And to show a block conditionally, you have to hide it first; otherwise "show" does nothing because it's already visible. Limits: file uploads cap at 10 MB on free, and since the fair use ceiling isn't public, ask support before a big launch.

Standout features
  • Logic, calculations and redirects on the free plan
  • Six logic actions, nested AND/OR conditions
  • No limit on number of conditions
  • Unlimited forms and responses on free
+Pros
  • ✓The deepest logic you can get for $0
  • ✓Builds like a doc, fast to learn
  • ✓Pro at $24/mo covers your whole team
−Cons
  • ✗Fair use ceiling isn't published
  • ✗10 MB file uploads on free
Verdict

Our top pick if you want real logic and don't want to pay for it. Torn between this and Fillout? See Tally vs Fillout.

Best for forms wired into your data

Fillout

4.2/5

Fillout's free plan gives you 1,000 responses a month with conditional logic, calculations, quiz scoring, prefill and hidden fields. Hidden fields are the quiet win here: data the respondent never sees but that travels with the submission, like a UTM source, a customer ID or a sales rep's name. Fillout can use them inside conditions.

Logic works at two levels. Page logic hides or shows whole pages or custom endings. Field logic shows a question based on an earlier answer. Conditions can read an answer, a URL parameter, a date or a calculated value. Real example: the link you email to existing customers carries ?customer=yes, and Fillout skips every qualifying question for them.

Paid tiers are mostly about volume: Starter at $15/mo billed yearly ($19 monthly) for 2,000 responses, Pro at $40 ($49 monthly) for 5,000, Business at $75 ($89 monthly) for unlimited. The Fillout badge only goes away on Pro. The catch: simple forms come together in minutes, but multi-condition logic has a real learning curve, and support is slower than the product.

Standout features
  • 1,000 responses/mo on free
  • Conditions on URL parameters, dates and calculations
  • Hidden fields and prefill on free
  • Page logic, field logic and custom endings
+Pros
  • ✓Most generous free volume with calculations
  • ✓Hidden fields usable inside conditions
  • ✓Clear tiers from 2,000 responses to unlimited
−Cons
  • ✗Fillout badge until Pro
  • ✗Multi-condition logic takes time to learn
Verdict

The pick when your form sits in the middle of your stack and needs to know where each person came from. For a plain contact form, Tally is enough.

Best for triaging requests to the right team

Jotform

4.0/5

Jotform has the widest set of condition types in this lineup. Its help docs list six: show/hide a field, update/calculate a field, enable/require a field, skip to or hide a page, change the thank-you page, and change the email recipient. That last one is the reason to pick it: depending on the answer, the notification goes to sales, support or HR, with no Zapier in between.

The free plan is a trial in disguise: 5 forms and 100 submissions a month. Bronze, at $34/mo billed yearly ($39 monthly), raises that to 25 forms and 1,000 submissions. Gold, at $99/mo billed yearly, gets you 100 forms and 10,000 submissions. If you have EU respondents, Jotform also offers data storage on its Frankfurt servers.

The limit came straight from a user on Jotform's own forum: the logic feels too basic for complex flows, with no nested conditions or multiple actions inside one rule, and support confirmed it isn't available. In practice you stack several simple rules instead of writing one rich one. The builder is also busy, with logic and calculation settings spread across several menus.

Standout features
  • Six condition types, including recipient change
  • Different thank-you page per answer
  • Calculated totals and scores
  • EU data storage option in Frankfurt
+Pros
  • ✓Easiest email routing in this list
  • ✓Thousands of templates to start from
  • ✓EU hosting available
−Cons
  • ✗No nested conditions within a rule
  • ✗Free plan capped at 5 forms and 100 submissions
Verdict

Pick it when every answer has to reach the right person. Compared to our number one: Jotform vs Tally.

Best for WordPress sites

Gravity Forms

3.8/5

Gravity Forms is a WordPress plugin, so the form lives on your site and the entries live in your database. Our full review scores it 4.7 on features and depth, and it earns it: field-level conditional logic, calculations, payments and notifications that go to a different recipient based on answers. For agencies running a fleet of client sites, it's often the default.

Pricing is per year and per site count: $59/yr for one site on Basic, $159/yr for three sites on Pro, $259/yr for unlimited sites on Elite. No free plan. The good news is renewal pricing stays flat. The less good news: the most useful add-ons need Pro or Elite.

Where it gets heavy: once notification logic grows, each recipient carries its own set of rules, and a heavily branched form turns into maintenance work. The builder feels dated and has no undo. Our habit: duplicate the form before you touch live logic, and name fields clearly, because rules show them by label. Already on WPForms? No need to switch: its Smart Logic also combines AND/OR conditions and sends conditional confirmations and notifications.

Standout features
  • Entries stored in your own WordPress
  • Conditional logic and calculations
  • Notifications routed by answer
  • Flat renewal pricing
+Pros
  • ✓No dependence on a third-party SaaS
  • ✓Built for agencies with many client sites
  • ✓Yearly license, not per response
−Cons
  • ✗No free plan
  • ✗Dated builder with no undo
Verdict

The pick if you run WordPress and want to own your data. Outside WordPress, it's not an option.

Best when a submission needs internal approval

Zoho Forms

3.9/5

We don't have a full Zoho Forms review yet, but it earns its spot here for one reason: it treats logic as a process, not just a path. Its official plan grid splits rules into three levels, all available on every plan, free included: field rules (show or hide a question), form rules (what happens on submit) and page rules (skip a page).

Paid plans add what others skip: advanced rules, a Set Value action that fills a field for you, and Deny Submissions, which blocks a form when a condition isn't met (handy for out-of-budget or late requests). They also add approval workflows, so a purchase request above a threshold goes to a manager while smaller ones go straight through.

The free plan holds up with 3 forms and 500 submissions a month. The catch is the ecosystem: Zoho Forms shines with other Zoho apps and is a bit less compelling alone.

Standout features
  • Field, form and page rules on free
  • Deny Submissions on paid plans
  • Approval workflows on paid plans
  • 500 submissions/mo on free
+Pros
  • ✓Logic built for internal processes
  • ✓Generous free submission cap
  • ✓Ties into the rest of Zoho
−Cons
  • ✗Approvals and Deny Submissions need a paid plan
  • ✗Only 3 forms on free
Verdict

The pick when a form triggers an internal decision. For customer-facing surveys, Tally or Fillout are simpler.

Nicest to fill out, if your volume stays low

Typeform

3.8/5

Typeform made the one-question-at-a-time form famous, and its logic fits that format. The pricing page describes logic that connects, skips and rearranges questions, adds scores and calculations, and shows different endings to different respondents. Hidden fields round it out. It's still the most polished experience in this list, and on brand surveys that shows up in completion.

Volume is the problem. Free stops at 10 responses a month. Basic, where Typeform's own grid lists conditional logic, costs $28/mo billed yearly ($39 monthly) for 100 responses. Plus is $56 ($79 monthly) for 1,000. In user reviews, it's the top complaint: "It works well but it is expensive." One successful launch and the cap is gone in days. Budget for your peak, not your average.

A tip from Typeform's community forum: when combinations pile up (say, six goals someone can tick together), nested logic becomes unreadable. Typeform's own answer was to redirect people, based on their answer, to separate forms instead of cramming everything into one. The branching map is clear on short flows and gets crowded fast on long ones.

Standout features
  • One question at a time, very polished
  • Different endings per respondent
  • Scores and calculations
  • Hidden fields to track the source
+Pros
  • ✓Best look for a brand survey
  • ✓Logic stays readable on short flows
  • ✓AI builder to draft a form fast
−Cons
  • ✗10 responses/mo free, 100 on Basic
  • ✗Branching map hard to read on long surveys
Verdict

Pay for the look, not the volume. On a budget, read Typeform vs Tally or the best Typeform alternatives.

Best for a form that reads like a landing page

Paperform

3.9/5

Paperform builds like a page: you write copy, drop in images, and slot questions in between. Conditional logic is on the free plan, which is capped at 30 submissions a month. That's enough to check your flow, not to run a real campaign.

The interesting part starts on Pro, at $49/mo billed yearly ($59 monthly). The calculation field outputs a price, an order total or a score, and conditional redirects send people to a different URL based on their answers. Concrete use: a quote form that computes the total, then sends high-budget leads to your booking page and everyone else to a resource page. Business is $124/mo billed yearly ($149 monthly).

The limit is in the grid: no calculation field and no conditional redirects on free. Tally and Fillout give you both for nothing. Paperform makes sense when layout matters as much as logic, like an order form that also has to sell.

Standout features
  • Form laid out like a document
  • Conditional logic on free
  • Calculation field on Pro
  • Conditional URL redirects on Pro
+Pros
  • ✓Most layout freedom in this list
  • ✓Price calculations for quote forms
  • ✓Answer-based redirects on Pro
−Cons
  • ✗30 submissions/mo on free
  • ✗Math and redirects locked to Pro
Verdict

Pick it when your form has to sell too. If you only need calculations, Tally gives them away.

A simple free option with endings and a calculator

forms.app

3.6/5

forms.app keeps showing up in conditional logic searches, and its official page says why: logic is on the free plan, along with multiple endings based on answers and a calculator field. That covers three of the four jobs in this comparison for free: jumps, different endings and simple math such as a quiz score.

Free gives you 5 forms, and the pricing page lists monthly submissions as unlimited on that plan. The first paid tier, Basic, is $19/mo billed yearly ($29 monthly), cheaper than Typeform or Paperform for similar use.

The catch: 5 forms go fast if you build one per campaign. And we didn't find the same depth as Tally on nested AND/OR conditions or blocking submission. For a quiz with a result or a two- or three-branch sign-up, it does the job well.

Standout features
  • Conditional logic on free
  • Multiple endings per answer
  • Calculator field
  • Unlimited submissions listed on free
+Pros
  • ✓Logic and math at $0
  • ✓Basic at $19/mo billed yearly
  • ✓Quick for scored quizzes
−Cons
  • ✗5 forms on free
  • ✗Less depth than Tally on complex conditions
Verdict

A solid free pick for simple flows. For combined conditions, Tally goes further.

The default if your team lives in Microsoft 365

Microsoft Forms

3.6/5

Microsoft Forms does one thing: branching. Based on the answer to a choice question, people jump to a later question or section. Each answer has one destination, and branching only moves forward, so no going back or looping. No show/hide on the same page, no calculations, no combined conditions.

The limits are known: 200 questions max per form, and a response cap that depends on the account (200 on a free personal account, 1,000 on a paid personal account, up to 5 million on a work or school account). One user on Microsoft's Tech Community described getting stuck at the 17th branch of a 34-option question, with no clear answer.

The tip people hunt for: branching isn't on the question itself, it's in the "…" menu at the top right of the form. And since everything flows forward, put every question in its final order before you add a single rule, or you'll redo the lot. For an internal poll, it's enough. For a customer form that needs to qualify or calculate, move to Tally or Fillout.

Standout features
  • Branching from a choice question
  • Included with a Microsoft account
  • Up to 5 million responses on work accounts
  • Up to 200 questions per form
+Pros
  • ✓No extra tool for a Microsoft 365 team
  • ✓No new account for your colleagues
  • ✓Zero learning curve
−Cons
  • ✗Forward-only branching
  • ✗No show/hide or calculations
Verdict

Fine for an internal poll with two or three paths. Past that, the logic runs out.

Free and familiar, but section jumps only

Google Forms

3.4/5

Google Forms has exactly one kind of logic: "Go to section based on answer". It triggers on multiple choice or dropdown questions, not checkboxes. You can't show or hide a single question, and you can't combine two conditions ("if they're in the US AND have 10+ employees"). There's no map of your rules either; you find them section by section.

The setup that works: one section per conditional question. Put the sorting question in its own section, point each answer to its matching section, and end each branch with "Go to section" back to the shared path. If someone might not fit any option, add an explicit "Something else" choice with its own destination. The free-text "Other" option can't trigger a jump.

It's free, and nobody needs instructions to fill it in. For a three-branch sign-up, it's the simplest choice. The moment you need to calculate a quote, hide a question on the same page or notify a different person per answer, switch tools.

Standout features
  • Section jumps on multiple choice or dropdown
  • Free with a Google account
  • Everyone already knows how to fill it in
  • Explicit "Something else" path for edge cases
+Pros
  • ✓Zero cost, zero setup
  • ✓Fine for two or three branches
  • ✓Share a link and you're done
−Cons
  • ✗No show/hide for a single question
  • ✗No AND/OR, checkboxes can't trigger jumps
Verdict

Good for a simple free flow. If you want to stay free with real logic, Tally does everything Google Forms can't.

Before you build

What breaks conditional logic in the wild

These come from our comparison, official help docs and user forums. They apply whichever builder you pick. For a broader ranking without the logic filter, see the best online form builders.

Map every path first

On paper or a whiteboard, draw every route: who sees which question, and where they end up. A quote form with three profiles and two budgets is already six paths. If you can't draw them, the builder won't show them any better, especially Google Forms and Typeform on long flows.

Walk each path in preview

Fill the form in preview once per path, using deliberately extreme answers. That's how you catch the person who never sees the contact question, or the jump that dumps people on the thank-you page too early. In Tally, remember jumps fire on "Next": the rule belongs on the question's page. And a question meant to appear conditionally has to start hidden, or a "show" rule changes nothing.

Know where the answers live

A conditional form often collects more than a contact form: budget, situation, sometimes health or family details. Ask where that data is stored before you pick. Jotform offers storage on its Frankfurt servers, and Gravity Forms or WPForms keep entries in your own WordPress database. For the rest, read the vendor's privacy page and check which plan unlocks regional hosting.

Too many combinations? Split the form

Past four or five branches that cross each other, one form becomes impossible to maintain. Typeform's forum gives the clean way out: one sorting question up front, then a redirect to a separate form per profile. Each form stays simple, and editing one won't break the others.

Budget for your peak

A monthly cap shuts your form off on the day it performs best. Typeform stops at 10 responses free and 100 on Basic, Paperform at 30 free, Jotform at 100. Take your best month last year, or your next campaign, and hold it against the cap. Tally (fair use) and Fillout (1,000 responses) leave more room for free.

Check which plan each action is on

"Conditional logic" on a features page doesn't tell you which actions you get. Paperform puts calculations and redirects on Pro. Zoho Forms keeps Deny Submissions and approvals for paid plans. Read the grid plan by plan, action by action, and list the ones you actually need.

  • Every path is drawn before you build
  • Conditional questions are hidden by default
  • Each path was walked in preview with extreme answers
  • The monthly cap covers your peak, not your average
  • The actions you need (math, redirect, recipient) are on your plan
  • A "Something else" option exists for edge cases
  • Hidden fields pass along the response source

FAQ

Your questions on conditional logic in forms

  • What is conditional logic in a form?

    It's a form's ability to change based on answers: skip questions, show new ones, calculate a result or send the submission to a specific person. A quote form that only asks for office size when someone picks "Business" is using conditional logic. The payoff: shorter forms for each respondent and better-sorted data.

  • Which free form builder has conditional logic?

    Tally has the most complete free logic: jumps, show/hide, calculations and redirects, with no cap on conditions. Fillout is close behind with 1,000 free responses a month and hidden fields. Zoho Forms keeps its basic rules on free with 500 submissions a month, and Jotform opens its standard core features on free with 100 submissions a month.

  • Does Google Forms support conditional logic?

    Only one kind: "Go to section based on answer", on a multiple choice or dropdown question. You can't hide a single question or combine conditions. The workaround is one section per conditional question. For anything more, Tally does for free what Google Forms can't.

  • Is Typeform's conditional logic available on the free plan?

    Typeform's official pricing grid lists conditional logic from the Basic plan, at $28/mo billed yearly. Even if you can sketch logic on free, the 10-response monthly cap makes it unusable for anything live. If you're comparing on budget, Tally and Fillout both give you logic plus far more responses at $0.

  • Can a form redirect to a different page based on answers?

    Yes. Tally does it on free, Paperform from Pro, and Typeform through different endings per respondent. Jotform swaps the thank-you page based on answers. It's handy for sending qualified leads to your calendar and everyone else to a resource page. Google Forms and Microsoft Forms can't.

  • How do I add branching in Microsoft Forms?

    Open the "…" menu at the top right of the form and pick the branching option. For each answer to a choice question, set the next question or section. Branching only moves forward, so put every question in its final order before you add rules.

  • Can I combine conditions with AND / OR?

    Yes in Tally, with nested condition groups, and in WPForms on WordPress, whose Smart Logic handles AND and OR. Jotform accepts several conditions in one rule but not nested ones, according to its own support. Google Forms and Microsoft Forms don't combine anything: one answer, one destination.

  • Can I send submissions to a different email based on the answer?

    Yes, that's Jotform's strength: one of its six condition types changes the email recipient. Gravity Forms does it on WordPress with conditional notifications. Elsewhere you usually need an automation tool (Make, n8n, Zapier) to read the answer and forward it.
