## Frequently Asked Questions

### Should I choose Formbricks or Typebot for product feedback and surveys in 2026?
Choose Formbricks (`formbricks/formbricks`, 13.1k stars) when you need targeted in-app micro-surveys, NPS score tracking, and feature feedback triggered by user actions natively inside your React/Next.js web app or mobile app. Choose Typebot.io (`baptisteArno/typebot.io`, 10.6k stars) when you want interactive, conversational forms, lead qualification chatbots, and multi-step onboarding funnels with visual drag-and-drop workflow routing.

### How do Formbricks and Typebot eliminate $1,600+/month Typeform and SurveyMonkey bills?
Commercial survey tools charge steep subscription tiers and meter responses ($0.10-$0.50 per response overage), easily running $1,650+/month for 25,000 monthly responses. Self-hosting Formbricks or Typebot on a single $35/month Docker VPS allows unlimited surveys, unlimited responses, and complete data privacy without third-party tracker injection.
