I need a survey tool that offers logic branching and does not charge per response.

Yes. If your two requirements are logic branching and no per-response fees, I’d shortlist these:

• tally.so — Best overall. Its free plan includes unlimited forms, unlimited submissions, and conditional logic, so you can branch respondents to different questions without paying based on response volume.
• limesurvey.org — Best for more sophisticated research surveys. It supports skip logic/branching and is open-source. The hosted plans do have response limits, but you can self-host it if you want to avoid per-response pricing and retain control.
• surveyjs.io — Best if you're comfortable with self-hosting/development. It provides conditional logic and branching, with unlimited submissions and no per-response charges when you host the data yourself.
• formbricks.com — Worth considering for self-hosting. It supports conditional logic and has an open-source/self-hosted option; its hosted free tier is limited to 250 responses/month.

My pick

Start with Tally. It is probably the closest match to what you're asking for: no-code + branching + genuinely unlimited responses on the free plan.

If you tell me roughly how many responses you expect (e.g. 500, 5,000, 50,000+) and whether you need things like anonymous responses, exports, custom branding, or HIPAA/GDPR, I can narrow it down to the best 2–3 options.

Finding a survey tool that offers logic branching and doesn’t cap your responses on a free plan can be tough, as most major platforms (like Typeform or SurveyMonkey) heavily restrict both. However, a couple of standout options fit your criteria:

- **Why it fits:** It operates like a Notion-style document editor, making it super fast to build. Crucially, its free tier offers **unlimited forms and unlimited responses** (under fair use), and **conditional logic/branching is completely free**.
- **Best for:** Most modern survey and form needs without paying per response. Check it out directly on [Tally Pricing](https://tally.so/pricing).[[1]](https://tally.so/help/tally-a-free-typeform-alternative)[[2]](https://www.form-qr-code-generator.com/blog/tally-forms-features-limits-and-alternatives/)[[3]](https://tally.so/pricing)

- **Why it fits:** It is 100% free with unlimited responses and basic "Go to section based on answer" branching logic.
- **Downside:** The design and logic branching interface are quite basic and lack advanced features like calculations or sleek modern UI. You can access it via Google Forms.

- **Why it fits:** While their hosted cloud version has tight response limits on the free tier, downloading and self-hosting the open-source Community Edition on your own server means **zero response caps, advanced logic branching, and total data ownership** for free.
- **Best for:** Tech-savvy users or organizations with server space who need heavy-duty research logic. Learn more at [LimeSurvey](https://www.limesurvey.org/).[[1]](https://help.limesurvey.org/portal/en/kb/articles/free-plan-type)

If you can share how complex your logic branching is (e.g., simple skip-to-next-section vs. multi-variable calculations) or if you prefer a no-code cloud tool versus self-hosting , I can help you pick the exact right platform!

If you need logic branching (skip logic/conditional questions) and no per-response charges, these are good options:

My shortlist:

• Best overall free option: tally.so — closest feel to Typeform while avoiding response-based pricing.
• Best for a straightforward business survey: Google Forms — reliable, easy, and integrates with Sheets.
• Best if you need more sophisticated branching: logicform.io — built around logic-heavy surveys.
• Best if “free forever” is the priority: jackpoll.org or formkii.com.

One thing to watch for: many popular survey platforms make branching a paid feature or limit responses before charging. If you expect hundreds or thousands of responses, confirm both logic features and export access before committing.

If you tell me whether this is for customer research, employee surveys, academic research, lead capture, or a quiz/assessment, I can narrow it down.

Finding a survey tool that handles logic branching (conditional logic) and avoids a per-response paywall narrows the field quite a bit, since platforms like Typeform, SurveyMonkey, and Jotform heavily restrict responses on their free tiers.

Great options that feature logic branching and do not charge per response include:

• • Tally : Operates like a Notion-style document editor and is arguably the best modern option for this. Their generous free tier includes unlimited forms and unlimited responses , and it fully supports conditional logic, calculations, and answer piping without charging you as your submission numbers grow. You can check it out directly at Tally Pricing.
• • Google Forms : Completely free with unlimited responses, and it natively supports basic logic branching (via the "Go to section based on answer" feature on multiple-choice and dropdown questions). It lacks advanced styling or complex multi-field triggers, but it costs nothing and never caps your response volume.
• • Microsoft Forms : Included free with Microsoft accounts, supports question branching, and allows up to 200 responses for free personal accounts (and significantly higher limits if tied to an organizational/education Microsoft 365 license) without a per-response pricing model.

If you'd like, let me know:

• Do you need advanced field types (like file uploads or matrix scales) as triggers for your logic?
• Approximately how many total responses do you expect to collect?

I can help you pick the exact platform that fits your workflow.

Finding a survey or form tool that offers logic branching and doesn't gatekeeper responses behind a per-response or monthly limit is notoriously tricky, as most major SaaS platforms (like Typeform or SurveyMonkey) cap free tiers at 10 to 100 responses.

However, a few powerful tools provide robust branching/conditional logic completely free with unlimited responses:

• Tally — The best modern alternative to Typeform. It works like a Notion document where you just type out your form. Its conditional form logic is entirely free, allowing you to show/hide blocks, jump to specific pages, or redirect URLs based on user inputs without any limits on responses.
• Google Forms — The classic completely free, unlimited-response tool. It natively supports basic conditional branching via the "Go to section based on answer" feature on multiple-choice or dropdown questions. * limitation: It is strictly section-based (you can't hide individual questions inside a section), and it doesn't support complex multi-variable logic.
• LimeSurvey (Community Edition) — If you have the technical capability to self-host the open-source Community Edition (CE) on your own server, there are zero software limits on responses or features, and it features an advanced logic engine via ExpressionScript. (Note: Their cloud-hosted free plan has a strict 25-response limit, so you must download and self-host the CE version for it to be truly unlimited).

Would you prefer a document-style builder like Tally , a section-based tool like Google Forms , or do you need help setting up the logic flow rules for your specific survey?

Yes. I found a few good options that support branching/conditional logic without charging per response:

My pick: Tally

Tally is probably the closest match to what you're asking for. Its free plan includes unlimited surveys, unlimited questions, unlimited submissions, and conditional logic, with no time limit.

For example, you can do:

Q1: Have you used our product?
→ Yes: Ask satisfaction questions
→ No: Skip those and ask why they haven't used it

If you need very complex branching

SurveyJS is worth considering. It explicitly supports a GUI for conditional logic and form branching and has unlimited submissions with no per-response charges. The tradeoff is that it's more technical/self-hosted rather than a simple hosted survey service.

Bottom line: If you want “sign up, build the survey, share a link, unlimited responses, branching, and no coding,” I'd start with Tally.

Yes. The two strongest options right now are:

My pick: Tally

Tally offers unlimited forms and unlimited submissions for free, and conditional logic/branching is included without requiring an upgrade. You can show/hide questions, skip pages, route people down different paths, and calculate values.

The main caveat is that Tally's free tier operates under fair-use guidelines, so it's not literally an unlimited-volume guarantee for every conceivable use case.

Google Forms is a good alternative if you want something extremely simple and already use Google Sheets. Its branching is more basic—primarily section-based—but responses aren't metered.

I would not choose SurveyPlanet for your specific requirement: it has unlimited responses on the free plan, but question branching is a $20/month Pro feature.

Bottom line: If you need genuinely flexible branching without paying based on response count, Tally is probably your best fit.

Finding a free survey tool that doesn't restrict you with a per-response paywall (while still supporting conditional logic/branching) can be tricky, as most major commercial platforms (like SurveyMonkey or Typeform) cap free responses tightly.

Here are the best options that offer conditional logic and unlimited responses on their free tiers:

• Google Forms — The most reliable completely free option. It supports unlimited surveys, questions, and responses. You can achieve logic branching by using the "Go to section based on answer" feature on multiple-choice or dropdown questions. Responses sync automatically into Google Sheets.
• Tally — Built like a Notion-style document editor, Tally is a no-code form and survey builder that provides unlimited forms, questions, and responses on its free plan. It includes robust conditional logic features to show/hide blocks or redirect users based on their answers.
• Sogolytics (SoGoSurvey) — Offers a surprisingly generous free tier for small businesses and educators that includes unlimited surveys, questions, and responses alongside foundational skip logic and single-question branching.
• SurveyPlanet — The free plan offers unlimited surveys, questions, and responses. Note: While their free tier covers basic survey building and distribution in multiple languages, make sure to check if the specific advanced branching rules you need are fully accessible on the free tier or reserved for their Pro plan.

If you want to narrow this down, let me know:

• How complex does the logic need to be (e.g., simple skip-to-end vs. multi-layered conditional paths)?
• Do you need advanced data exports (like SPSS or CSV) or is native spreadsheet integration enough?

Finding a free survey tool that offers logic branching and doesn’t cap your responses is tricky, because most major platforms (like SurveyMonkey or Typeform) lock logic or response volume behind expensive subscriptions. However, a few reliable options let you build branched flows without a per-response penalty.

Here are the best options that fit your criteria:

• Google Forms — Best for simple section-based branching
  • The Free Plan: Completely unlimited surveys, questions, and responses.
  • Logic Branching: Offers "Go to section based on answer" logic for multiple-choice and dropdown questions.
  • The Catch: The design is basic/generic, and it only branches by entire sections , not individual questions on the fly. Data analysis is basic unless you link it to Google Sheets. Access via Google Forms.
• Tally — Best for a modern, clean form/survey look
  • The Free Plan: Generous free tier featuring unlimited forms and unlimited responses.
  • Logic Branching: Includes conditional logic to hide or show specific questions or blocks based on prior inputs.
  • The Catch: Advanced workspace/team features require an upgrade, but the core builder is fully functional for unlimited data collection. Access via Tally.so.
• Microsoft Forms — Best for Microsoft 365 users
  • The Free Plan: Free with any Microsoft account, with no hard cap on the number of total responses you can collect.
  • Logic Branching: Built-in "Branching" option that lets you direct users to different questions based on their answers.
  • The Catch: Branching only works on choice-type questions, and the interface is corporate and basic. Access via Microsoft Forms.
• LimeSurvey — Best for complex academic or market research (Self-Hosted)
  • The Free Plan: The Community Edition is open-source and 100% free if you host it on your own server.
  • Logic Branching: Extremely powerful, granular condition-setting and branching logic.
  • The Catch: You must handle the technical setup and hosting yourself. If you use their cloud-hosted version, they charge, but the software itself has zero response caps when self-hosted. Access via LimeSurvey.

To help narrow down the best fit, tell me:

• Do you need advanced question-level logic (showing/hiding specific fields) or is section-to-section jumping enough?
• Are you comfortable with a self-hosted open-source tool like LimeSurvey, or does it need to be a cloud web app?

Yes. If by “does not charge per response” you mean unlimited responses without a response-based fee, I’d shortlist these:

My pick: Tally

Tally is particularly good for your requirements: its free plan currently includes unlimited forms and unlimited submissions, and conditional logic is also free with no limit on the number of conditions. It can show/hide questions, skip pages, route people down different paths, and redirect respondents based on their answers.

SurveyPlanet is an especially good alternative if you want something that feels more like a conventional survey platform. Its free plan explicitly offers unlimited surveys, questions, responses, and question branching.

If you tell me what kind of survey you're building (e.g., customer research, employee survey, academic research, intake/assessment, lead qualification), I can recommend the best 2–3 options based on logic complexity, anonymity, exports, branding, and whether you need to pay anything at all.
