The short version

  • Only Fillout has a free tier, so it costs nothing to try first.
  • Each has a real cost: Adverity no published pricing and no tiers; every quote is bespoke, which the vendor states plainly; 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.
  • They diverge on capability: Adverity covers Data aggregation, Fillout covers Unlimited seats and forms.
  • Prices and features above were last checked on 31 August 2026.

Fillout

  • An organisation with many occasional form builders, where per-seat pricing elsewhere would cost more than the forms are worthnot Adverity
  • Replacing a survey tool, a scheduling tool and a payment link with one form that does all threenot Adverity
  • Public forms that must keep collecting through an unexpected traffic spike rather than shutting off at a quotanot Adverity

Where each one falls short

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

Adverity

  • No published pricing and no tiers; every quote is bespoke, which the vendor states plainly
  • An ETL and data layer rather than a reporting tool, so it needs a BI destination alongside it

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.

Answered from the vendors’ own pages

Adverity: Does Adverity offer transparent published pricing?

No. Adverity does not publish fixed pricing plans. Instead, each customer receives a custom quote tailored to their specific needs and requirements, as stated on their pricing page.

Source
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.

Adverity: How is Adverity pricing determined?

Adverity pricing is based on individual customer requirements. Interested buyers must complete a form and contact the sales team to receive a customized quote, making it quote-only with no published rate card.

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.

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.
