These three tools aren't substitutes for each other — they automate three unrelated operational tasks: collecting form and survey data, screening payments for…

Three different jobs, not three competitors
forms.app collects data, FraudLabs Pro screens transactions for risk, and freedns.afraid.org resolves domain names to IP addresses. There's essentially no overlap in what these tools do, so 'which is best' depends entirely on which of the three problems you're solving.

Free-tier structure differs meaningfully
forms.app offers unlimited responses on its free plan, a generous approach for a form builder where competitors often cap submissions. FraudLabs Pro instead caps its free tier by volume (500 validations per month), reflecting its usage-based, per-transaction pricing model.

freedns.afraid.org is the cheapest paid entry point
Premium DNS plans start around $5/month, undercutting forms.app's paid tiers, which start near $16/month for a fuller-featured SaaS product with AI-assisted form building.

AI is a differentiator only for forms.app
forms.app markets itself as AI-assisted for building forms, surveys, and quizzes. Neither FraudLabs Pro nor freedns.afraid.org advertises AI features in the data available — both read as traditional, purpose-built utility services.

No. They solve completely different problems — forms.app is a form/survey/quiz builder, FraudLabs Pro is a payment fraud screening service, and freedns.afraid.org is a DNS hosting provider. They're grouped here because they're all narrow, automation-oriented utilities, not because they replace each other.
All three have free tiers, but the entry points differ: forms.app gives unlimited form responses free, FraudLabs Pro gives 500 fraud validations per month free, and freedns.afraid.org gives free DNS hosting with premium plans from about $5/month. There's no single 'cheapest' answer since they meter different things.
Likely FraudLabs Pro, to screen incoming orders for fraud signals like mismatched IP, email, and address data. A store might separately use forms.app for contact or intake forms, and freedns.afraid.org only if it's self-hosting infrastructure that needs dynamic DNS.
Based on the available pricing data, no — all three list self-serve starting prices (including free tiers), unlike tools that require a sales contact before you can see pricing.
The two tools aren't documented as having a direct integration with each other. forms.app is a general-purpose form and survey builder, while FraudLabs Pro is a dedicated fraud-screening API; combining them would require custom setup on the merchant's side rather than a built-in connection.
