Questions & Answers

As answered by people managing GriffinForms and Formstack.

What makes your product unique?

GriffinForms's answer

GriffinForms handles form scenarios that most WordPress form plugins treat as edge cases: multi-step forms with per-step validation and conditional page branching, WordPress user registration with pending approval and payment-gated account creation, and compliance-ready submission storage with GDPR and HIPAA profiles — all in a single free plugin. The builder includes a live checks system that flags spam configuration gaps, missing registration mappings, and compliance risks before a form is published, which reduces misconfiguration on complex forms. AI-assisted editing (Griffin Assist) lets users create and modify forms from plain-English prompts without rebuilding from scratch.

Why should a person choose your product over its competitors?

GriffinForms's answer

GriffinForms is built for forms that do more than collect an email address. If you need a contact form, any plugin will do. If you need a multi-step registration form that creates a WordPress account, holds it for admin approval, and only activates it after a Stripe payment clears — GriffinForms handles that in one place without stitching together separate plugins. It also includes four independent spam protection layers, native rate limiting, compliance profiles, and detailed submission timelines with audit logs. Everything is included free — there is no gated tier for multi-step, payments, or registration.

How would you describe the primary audience of your product?

GriffinForms's answer

WordPress developers, agencies, and site owners who build forms for real workflows — membership sites, institutional intake, event registration, client onboarding, or any form that involves payments, file uploads, user account creation, or compliance requirements. It suits users who have outgrown simple contact form plugins and need conditional logic, multi-step flows, and submission traceability without switching to a hosted form SaaS.

What's the story behind your product?

GriffinForms's answer

GriffinForms was built by an independent developer who kept running into the same wall: WordPress form plugins handle simple contact forms well, but break down when forms need to do real work — registration, payments, multi-step flows, compliance. Rather than continue patching together multiple plugins with fragile integrations, GriffinForms was built from the ground up as a single plugin designed for workflow-heavy form scenarios. It has been in active development for over a year with frequent releases, expanding from core form building into user registration, Stripe payments, AI-assisted editing, and compliance tooling.

Which are the primary technologies used for building your product?

GriffinForms's answer

PHP 8.2+, WordPress 6.6+, JavaScript (vanilla + WordPress block editor APIs), Bootstrap 5 for frontend form rendering, Stripe API for payments, REST API for external integrations, and AI provider APIs (OpenAI) for the Griffin Assist feature.

Who are some of the biggest customers of your product?

GriffinForms's answer

  • GriffinForms is an early-stage plugin. We do not have publicly referenceable enterprise customers at this stage.
