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.

VWO

  • Growth plan restricted to 1 workspace and 0 custom attributes

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.

VWO: Is there a free trial available?

Free for 30 days. No credit card required to start the trial.

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.

VWO: Are there limits on users or metrics?

Run unlimited optimization at scale with no limit on variations, account users, metrics, session recordings, or integrations.

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.
