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.
Parabola
- The Basic plan allows 1 user and 1,000 credits with limited AI
- No price is published for either the self serve or the business tier
- Credits are consumed when agents run, and further credits are bought pay as you go
- Role based access control, SSO, version history and SLAs all sit on the unpriced business plan

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.
Parabola: How much does Parabola cost?
Parabola does not publish specific pricing rates. The service uses a credit-based system where credits are consumed when agents run. Self-serve plans include a monthly credit allotment, and Business plans require a custom quote.
SourceFillout: 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.
Parabola: Does Parabola offer a free plan?
Yes, Parabola offers a free tier indefinitely for self-serve users with limited credits and basic features including the Prowork agent builder and pre-built integrations.
SourceFillout: 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.
Parabola: What features are included in Parabola's Business plan?
Business plans include all self-serve features plus automation engineer enablement, deployment support, proof of concept on production data, enterprise security with SSO, service level agreements, and a dedicated account manager.
SourceFillout: 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.
Parabola: Can I upgrade from free to Business later?
Yes, customers can start on free or self-serve plans and upgrade to Business plans at any time.
