Typeform builds forms that show one question at a time and adapt based on previous answers, so an online survey feels closer to a conversation than a wall of fields. It supports quizzes, lead capture, NPS, registration, and research with logic jumps, hidden fields, and a large library of integrations (Slack, Notion, HubSpot, Zapier, Google Sheets).

Free plan covers small projects with limited responses; paid plans unlock higher limits, custom branding, payment collection, and analytics. Web-based, no install required.
