Typebot is a fully open-source conversational app builder built with a modern stack, offering a visual drag-and-drop flow editor backed by 45+ composable building blocks. It supports multichannel deployment via custom domains, embedded containers, popups, chat bubbles, WhatsApp, and raw HTTP requests, making it programmable from any language or service. The platform integrates natively with OpenAI (and multiple other generative AI providers), Google Sheets, Google Analytics, Meta Pixel, and Zapier, and exposes easy-to-use APIs for custom implementations. Developers can extend bots with custom JavaScript and CSS, link sub-typebots for modular flows, and export analytics data via CSV for external processing.
