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.; Insider delivery depends heavily on the assigned account team, so results vary by region and a team change mid-contract can be felt immediately in campaign output.
  • They diverge on capability: Fillout covers Unlimited seats and forms, Insider covers Architect journeys.
  • 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.

Insider

  • Delivery depends heavily on the assigned account team, so results vary by region and a team change mid-contract can be felt immediately in campaign output.
  • The suite is licensed by module, so the platform fee quoted at the start typically excludes the channels and predictive features that make the business case work.
  • Template-driven web personalisation targets the rendered DOM, which breaks on single-page applications that re-render after the template applies unless a developer wires in the framework hooks.
  • Reporting exports are limited compared with warehouse-native tools, so teams that want campaign data alongside finance data end up pulling it through the API on a schedule.
  • Contracts are annual and negotiated per traffic band, so a seasonal spike in visitors can push you into a renegotiation rather than a metered overage.

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.

Insider: Is WhatsApp actually usable at scale here?

Yes. It is a supported primary channel with catalogue and template message support, though WhatsApp conversation fees from Meta are passed through and are separate from the licence.

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.

Insider: Can we run it without vendor help?

You can, but the pricing assumes a managed relationship. Teams with strong in-house campaign operations often find they are paying for services they do not use.

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.

Insider: Does it work for B2B?

Rarely a good fit. The segmentation, recommendations and channel mix are built around high-frequency consumer behaviour.

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.
