| Compare | Core Forms | Formstack |
|---|---|---|
| Verdict | Depends | Depends |
| Best for | WordPress site owners | Regulated teams (healthcare, finance) needing secure, auditable data collection |
| Who it's not for | Non-WordPress websites | Solo users needing a basic contact form . free tools suffice |
| Privacy | No known public vulnerabilities found in the sources reviewed.⁷ | SOC 2 and compliance tooling claimed; one public CVE affects the WordPress plugin, not the core platform.11 |
| Support quality | No support evidence found | No evidence in sources |
| Public sentiment | Early third-party WordPress reviews (InfluenceWP, IndependentWP) are favorable, but real user review volume is still minimal.³ | Independent user reviews are scarce; the available testimonial praises Formstack as the most user-friendly form builder.⁸ |
| Biggest gotcha | A 100-customer vendor means support depth and future updates aren't guaranteed.⁶ | Forms, Documents, and Sign are separate products . needing all three stacks subscription costs fast.⁸ |
