The short version
- 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.; Microsoft Clarity no paid tier means no premium support; enterprise SLAs and dedicated account management are unavailable

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.
Microsoft Clarity
- No paid tier means no premium support; enterprise SLAs and dedicated account management are unavailable
- Dependency on JavaScript tracking; websites with strict CSP (content security policy) may struggle with integration
- Session replay is limited to browser-based interactions; native app behaviour in web wrappers is not captured
- AI Chat and summaries require adequate session volume; low-traffic sites lack sufficient data for meaningful pattern detection
- Privacy masking is automatic but lacks granular configuration; custom masking rules for proprietary data require workarounds

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.
Microsoft Clarity: Is Microsoft Clarity truly free?
Yes. Microsoft Clarity is completely free with no traffic limits, no paid tier, and no restrictions based on session volume. It integrates with web properties via a single tracking snippet.
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.
Microsoft Clarity: Does Clarity comply with GDPR and CCPA?
Yes. Clarity automatically masks sensitive form field data before transmission and supports privacy-by-default configuration. EU and California data residency options are available.
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.
Microsoft Clarity: Can Clarity track mobile apps?
Yes. Clarity provides native SDKs for iOS and Android, as well as support for React Native and Flutter apps.
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.
