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

Microsoft Power Automate

  • Free plan limited to 750 flow runs/month and standard connectors only; premium connectors require paid plans
  • Not suitable for long-running workflows; can fail unexpectedly without warning
  • Limited to simple linear logic; fails with complex workflows involving multiple stakeholders
  • Tasks cannot automate at scale when requiring more than approximately 60 users

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.

Microsoft Power Automate: Is Power Automate included with Microsoft 365?

Yes. If you have an eligible Microsoft 365 subscription, you can use Power Automate at no extra cost for flows relying only on standard connectors (SharePoint, Outlook, Teams). Premium connectors (Salesforce, SAP, Oracle) require paid plans.

Source
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.

Microsoft Power Automate: How many flow runs are allowed on the free plan?

Power Automate's free tier (included with Microsoft 365) is limited to 750 flow runs per month and standard connectors only. Out of 900+ total connectors, the free plan only includes Microsoft ecosystem apps and limited third-party apps.

Source
Formstack: Is it HIPAA compliant?

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

Microsoft Power Automate: What's the difference between Premium and Process plans?

Premium ($15/user/month) provides attended automation with cloud flows and standard RPA. Process plan ($150/bot/month) enables unattended automation where bots run without human intervention on virtual machines for high-volume, repetitive tasks.

Source
Microsoft Power Automate: Does Power Automate support long-running workflows?

No. Power Automate is not suitable for long-lasting workflows because they can run without warning and fail unexpectedly. The platform is built for linear, branching logic (if-then) rather than complex, multi-step business processes involving multiple stakeholders.
