Form Builders With Unlimited Free Responses
Updated June 9, 2026
Only a handful of form builders offer genuinely unlimited free responses in 2026: Formkii (truly unlimited, no credit card), Google Forms (unlimited within your 15 GB of Drive storage), and Tally (unlimited under a fair-use policy). Others advertise 'unlimited' with fine print — Microsoft Forms caps each form at 200 responses, and StrawPoll is unlimited only for polls, not full forms. This guide spells out exactly what 'unlimited' means for each.
| Tool | Free responses | Paid from | Best for |
|---|---|---|---|
| Formkii | Unlimited | $0 — free | unlimited free responses across forms, surveys, quizzes, polls, and Q&A |
| Google Forms | Unlimited (15 GB Drive cap) | $7/user/mo (annual) | Quick, free, no-frills surveys inside the Google ecosystem |
| Tally | Unlimited (fair use) | $24/mo (annual) — Pro | Startups and creators who want unlimited free forms |
| StrawPoll | Unlimited (ad-supported) | ~$5-8/mo (annual, unverified) | Quick one-off straw polls shared by link |
| Fillout | 1,000/month | $15/mo (annual) — Starter | Teams building forms on top of Airtable, Notion, or Sheets |
| Zoho Forms | 500/month | ~$10/mo (annual, unverified) | Cheap high-volume business forms inside the Zoho ecosystem |
| Microsoft Forms | 200/form (free account) | ~$8.33/mo ($99.99/yr) | Quizzes and internal surveys inside Microsoft 365 organizations |
'Unlimited free responses' is one of the most abused phrases in the form-builder market. Some tools mean it literally; others mean unlimited until a storage cap, a fair-use line, or a per-form ceiling. We checked the fine print on each tool below so you know precisely where the limit actually sits.
- What 'unlimited' really means for each tool (cap, storage, fair-use, or per-form)
- Whether the limit is per form, per month, or account-wide
- Which builder features survive on the free unlimited tier
- Branding and other free-tier trade-offs
- When a capped tool is still the better choice
Formkii is our product and is genuinely uncapped, but we're precise about the others rather than lumping them together — Microsoft Forms in particular caps each form at 200 responses, which we state plainly. Honesty about the fine print is the whole point of this page.
Formkii
Truly unlimited, no asteriskThat's usFormkii's free plan is unlimited in the literal sense: unlimited forms, unlimited questions, and unlimited responses, with no credit card and no storage or fair-use ceiling called out. Conditional logic, themes, and CSV export are included. The honest trade-off isn't a response cap — it's the missing extras: no payment collection, no integration marketplace, and a smaller template library than incumbents.

Best for: unlimited free responses across forms, surveys, quizzes, polls, and Q&A
Google Forms accepts unlimited responses, but they count against your free 15 GB of Google Drive storage — so in practice the limit is how much file and response data you store, not a response count. For text-based forms that's effectively unlimited for most users. The trade-offs are a generic look, weak conditional logic, and no payments.
Unlimited (15 GB Drive cap) responses · Unlimited forms
Basic visual customization only (colors, fonts, images) · No true per-question conditional logic (section-based branching only) · No built-in payments · Limited analytics beyond response summaries
From $7/user/mo (annual)
- Genuinely free and unlimited forms/responses
- Seamless Google Sheets/Drive integration
- Familiar, zero-learning-curve interface
- Dated, generic look with minimal branding control
- Weak conditional logic and no payments
- Limited reporting/analytics
Best for: Quick, free, no-frills surveys inside the Google ecosystem
Tally offers unlimited forms and responses free under a fair-use policy — meaning there's no hard number, but extreme volume could draw a fair-use review. For nearly all users it behaves as unlimited, and conditional logic, calculations, and Stripe payments are free too. Branding removal, custom domains, and drop-off analytics require Pro at $24/mo.
Unlimited (fair use) responses · Unlimited forms
'Made with Tally' branding on forms · 10 MB per-file upload limit · No custom domains or custom email domain · No partial-submission capture or advanced analytics

- Fewer enterprise/compliance features
- Branding removal requires Pro
Best for: Startups and creators who want unlimited free forms
StrawPoll allows unlimited free polls and unlimited participants with no signup, but it's a poll maker, not a full form or survey builder — few question types and limited logic. Voters also see ads on the free plan. If your 'form' is really a single-question vote, StrawPoll's unlimited free tier is unbeatable; for multi-field forms, look elsewhere.
Unlimited (ad-supported) responses · Unlimited polls forms
Participants see advertisements · 50 email invites per month · No custom poll links or external links in description · Some features require confirmed email address
From ~$5-8/mo (annual, unverified)
- Fastest way to spin up a simple one-question poll, no signup
- Unlimited free polls and participants
- Solid anti-cheat (bot/VPN/duplicate blocking)
- Ads shown to voters on the free plan
- Not a real form/survey builder — single-poll focused, few question types
- No live presentation mode, analytics are basic
Best for: Quick one-off straw polls shared by link
Fillout doesn't claim unlimited — its free plan allows 1,000 submissions a month across unlimited forms, which clears most needs while staying honestly capped. You get 50+ field types, conditional logic, payments, and strong Airtable/Notion/Sheets sync. Analytics are thin, and a branding badge stays until you upgrade ($15/mo). Above 1,000/month you'd pay or move to a truly unlimited tool.
1,000/month responses · Unlimited forms
Fillout branding badge · 20 MB max file upload size · No custom themes, CAPTCHA, custom emails, analytics, or custom domains
From $15/mo (annual) — Starter

- Best-in-class Airtable, Notion, and Google Sheets native integrations
- Built-in scheduling (Calendly-style) inside forms

- Granular permissions locked to Enterprise
Best for: Teams building forms on top of Airtable, Notion, or Sheets
Zoho Forms is often grouped with 'unlimited' tools but isn't: its free plan caps submissions at 500 a month and forms at 3. That's higher than many rivals and fine for moderate volume, with strong mobile and offline capture. For genuinely unlimited free responses you'd need Formkii, Google Forms, or Tally instead.
500/month responses · 3 forms forms
1 user · 200 MB storage · 'Powered by Zoho' branding · Max 10 payment submissions
From ~$10/mo (annual, unverified)
- Very cheap entry price with high submission caps
- Strong mobile apps with offline form submission
- Approval workflows and document merge on mid tiers
- Free plan limited to 3 forms
- Design/theme customization weaker than Typeform-style builders
- Best value mostly realized if you already use Zoho products
Best for: Cheap high-volume business forms inside the Zoho ecosystem
Microsoft Forms is frequently mislabeled as unlimited, but free personal accounts cap each form at 200 responses — and once a form hits 200, it permanently stops accepting responses with no way to reopen it on the free tier. Microsoft 365 business and education plans raise this dramatically (up to millions), but the free personal limit is a hard 200 per form. Don't rely on it for high-volume collection.

- Simple, fast quiz and poll creation with auto-grading
- Enterprise-grade compliance via Microsoft 365

How to choose for unlimited free responses
If you need a literal no-cap free tier, Formkii is the cleanest answer, with Google Forms (Drive-limited) and Tally (fair-use) close behind for typical use. Treat 'unlimited' claims skeptically: Microsoft Forms caps each form at 200, StrawPoll is unlimited only for single-question polls, and Zoho Forms tops out at 500 a month. Match the real limit to your expected volume, then check that the features you need survive the free tier.
Estimate your peak monthly volume, not your average. A form that averages 100 responses but spikes to 1,000 during a campaign will blow past a 200- or 500-cap tool exactly when it matters most — a genuinely uncapped tool avoids that failure mode.
Frequently asked questions
Which form builder has truly unlimited free responses?
Formkii offers genuinely unlimited free responses with no cap or credit card. Google Forms is unlimited within your 15 GB of Drive storage, and Tally is unlimited under a fair-use policy. These three are the closest to literally unlimited among free form builders.
Does Microsoft Forms have unlimited responses?
No. Free personal Microsoft accounts cap each Microsoft Form at 200 responses, after which the form permanently stops accepting responses with no way to reopen it for free. Microsoft 365 business and education plans raise the limit dramatically, but the free personal tier is hard-capped at 200 per form.
Is Google Forms really unlimited?
Effectively, yes, for most users. Google Forms accepts unlimited responses, but they count against your free 15 GB of Google Drive storage. For text-based forms you're unlikely to hit that ceiling, but heavy file-upload forms could, in which case you'd need more Drive storage.
What does 'fair-use unlimited' mean on Tally?
Tally has no hard response number on its free plan, but reserves the right to review accounts with extreme usage under a fair-use policy. In practice it behaves as unlimited for nearly all users, including those collecting thousands of responses, while preventing abuse of the free tier.
