The short version

  • Only Fillout has a free tier, so it costs nothing to try first.
  • Each has a real cost: Fillout the Business plan is marketed with unlimited responses but the fair use policy names thresholds of 30,000 submissions a month, 250,000 in total, 500 forms per account and 50 GB of uploads a month, above which the vendor may limit or suspend features, so unlimited means unmetered rather than uncapped.; Supermetrics every package includes only 1 core destination; sending the same data to a second destination is a paid extra
  • They diverge on capability: Fillout covers Unlimited seats and forms, Supermetrics covers Multi-source data connectors.
  • Prices and features above were last checked on 31 August 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Fillout

  • The Business plan is marketed with unlimited responses but the fair use policy names thresholds of 30,000 submissions a month, 250,000 in total, 500 forms per account and 50 GB of uploads a month, above which the vendor may limit or suspend features, so unlimited means unmetered rather than uncapped.
  • EU data residency begins on the Team plan at 250 USD per month, more than three times the Business price, and is not applied automatically; you must upgrade and then raise a support request to be moved.
  • The Team plan is hidden behind a secondary tab that does not render without interaction, so buyers reading the pricing page see Business at 75 USD as the top self-serve tier and only discover the 250 USD step when they ask for single sign-on or EU hosting.
  • The enterprise marketing page lists hosting in the United States, EU, United Kingdom, Australia and Canada, but the security documentation and subprocessor list name only the United States and the EU, so three of those five regions should be confirmed in writing before they are relied on.
  • The vendor is SOC 2 Type 2 but claims neither ISO 27001 nor HIPAA anywhere in its documentation, and it is angel-funded with no disclosed institutional round while the parent company now trades as Zite and ships a separate AI application builder.

Supermetrics

  • Every package includes only 1 core destination; sending the same data to a second destination is a paid extra
  • The Starter plan at 49 EUR per month billed monthly includes 1 user, 3 data sources and 3 accounts per data source
  • Data refreshes are weekly on Starter, daily on Growth and hourly on Pro; on-demand refreshes require Enterprise
  • Refresh scheduling on those tiers is stated for Google Sheets only
  • Snowflake and BigQuery data warehouse destinations require the Enterprise package
  • SAML SSO is Enterprise only; lower tiers get basic single sign-on
  • Data transformations, data residency and region control, multiple teams and Management API access are Enterprise only
  • Enterprise carries no published price and is quote only
  • The 20% saving is only available on yearly billing
  • AI credits are metered per plan at 4,000 monthly on Starter and 12,000 on Growth

Answered from the vendors’ own pages

Fillout: Are seats really unlimited?

Yes. The vendor states there are no per-seat charges on any plan, including Free, and forms are unlimited too. Responses per month is the only meter below the Business tier.

Supermetrics: How much does Supermetrics cost?

Supermetrics offers three subscription plans: Starter at EUR 49 per month, Growth at EUR 199 per month, and Pro at EUR 499 per month. Annual billing provides a 20% discount. Enterprise plans require a custom quote.

Source
Fillout: What happens when I exceed my response quota?

Nothing breaks. Forms keep collecting, and you can upgrade, buy bulk submissions or wait for the monthly reset.

Supermetrics: Can I add extra users or data sources to my Supermetrics plan?

Yes, additional features are available for all plans. Additional users cost EUR 29 to EUR 124 per month depending on plan tier, and additional data sources cost EUR 29 to EUR 37 per month. Additional destinations and ad accounts also carry separate monthly fees.

Source
Fillout: Can I host respondent data in the EU?

Only from the Team plan at 250 USD per month, and only after contacting support to switch. Note that email and payment subprocessors remain in the United States regardless.

Fillout: Is the Business plan really unlimited responses?

It is unmetered, not uncapped. The fair use policy names roughly 30,000 submissions a month as the point at which the vendor may intervene, so treat that as the practical ceiling.
