The short version

  • Only SurveyLegend has a free tier, so it costs nothing to try first.
  • Each has a real cost: Formstack more expensive than form builders that only collect, which is the fair comparison for simple use; SurveyLegend every paid tier can collect more responses than it can export, with Pro gathering 5,000 per survey but exporting only 1,000 and Business gathering 20,000 but exporting 10,000, so data you have paid to collect can be stranded inside the product.
  • They diverge on capability: Formstack covers Form builder, SurveyLegend covers Per survey response limits.
  • 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.

Formstack

  • More expensive than form builders that only collect, which is the fair comparison for simple use
  • Document generation and signature sit in higher tiers, so the headline price is not the working price
  • The interface has accumulated features over a long life and shows it
  • Overkill where a form only needs to collect an answer

SurveyLegend

  • Every paid tier can collect more responses than it can export, with Pro gathering 5,000 per survey but exporting only 1,000 and Business gathering 20,000 but exporting 10,000, so data you have paid to collect can be stranded inside the product.
  • The free Starter plan cannot export data at all, only preview it in the live analytics, which makes it a demonstration rather than a usable plan and means any real project starts as a paid one.
  • The vendor claims neither SOC 2 nor ISO 27001 nor any third-party audit, and its GDPR page does not disclose hosting location, subprocessors or transfer mechanisms, so an enterprise security review will stall regardless of how good the residency story is.
  • The integration list runs to roughly four connectors with no native Zapier, Make, Slack, Teams, HubSpot or Airtable support, so anything beyond Google Sheets or Mailchimp has to be built against the API, which itself is unavailable below the Business tier.
  • No seat, collaborator or team permission model is documented anywhere in the pricing, features or user guide, so an organisation that needs several people to share and administer surveys has no described way to do it.

Answered from the vendors’ own pages

Formstack: What does Formstack cost?

It publishes tiered monthly pricing; document generation and e-signature sit in higher tiers, and HIPAA-capable plans are priced separately.

SurveyLegend: Where is my data stored?

In Frankfurt, Germany, on DigitalOcean, on every plan including the free one, with backups also held in Frankfurt. There is no United States transfer and no residency upgrade to buy.

Formstack: What makes it different from a plain form builder?

It generates documents from submissions and collects signatures on them, which is the step that otherwise involves retyping form data into a template.

SurveyLegend: What is the catch with the free plan?

You cannot export your data. You can build three surveys, collect a thousand responses each and view the analytics, but getting the raw responses out requires a paid plan.

Formstack: Is it HIPAA compliant?

It offers HIPAA-capable plans for regulated data. That is a plan-level feature, not the default.

SurveyLegend: Why does Pro cost 170 USD a year when the page shows 15 USD a month?

The published annual total is 170 USD, which is ten dollars below twelve times the stated monthly-equivalent rate. Both figures are printed on the vendor pricing page.

SurveyLegend: Is it suitable for an enterprise rollout?

Probably not. There is no SOC 2 or ISO 27001 certification, no documented team or permission model, and support is by email with phone access only on the top tier.
