The honest answer
A conversational form builder with common field types, themes, branching, and response exports is very achievable. Collaboration, enterprise controls, sophisticated analytics, and a broad integration catalogue are the expensive layers.
The hard parts
What actually makes this difficult

- Complex branching graphs
- Spam and abuse controls
What you lose
The parts that make the paid product hard to replace

- Advanced research analytics
People still pay for Typeform because exceptional polish; integration breadth; team and enterprise governance.

Before you start
Typeform build questions
Can I vibe code Typeform?
Yes, particularly for a niche workflow. Start with a small question schema and an excellent respondent experience instead of cloning every field and integration.
Is the form builder or renderer harder?
The builder creates more state-management work, while the renderer creates accessibility and validation edge cases. Design one shared schema for both.
Can it be static?
The marketing page can be static, but accepting and storing real responses requires an API and database or a managed form backend.
