Typebot
Open-source visual builder for creating conversational chatbots and smart forms without writing code. Drag-and-drop flow editor connects to OpenAI, Claude, and custom APIs. Self-host on your own infrastructure for full data control or use the managed cloud. Great for indie hackers and agencies building lead capture bots and onboarding flows.
Pi
Pi, from Inflection AI, is an empathy-first 'personal AI' tuned for supportive, natural conversation and voice rather than tasks. It's free with no paid consumer tier (now with some message caps), works across web and mobile, and has a uniquely warm, low-friction tone with eight voices. But after Inflection's founding team left for Microsoft in 2024 and the company pivoted to enterprise, Pi has sat in maintenance mode -- it still runs reliably, but the roadmap is uncertain and the feature set is frozen. It's lovely for companionship, but not something to build a workflow on.
Typebot edges Pi on aggregate — 83 vs 56.
The best open-source chatbot builder available -- self-hosting is genuinely free, but the cloud pricing catches up fast. Pi still wins for buyers who prioritise genuinely free, no card, no paid upsell. Both tools are independently scored — the right pick depends on which dimensions matter most for your workflow.
