A framework for choosing between building, buying, or adapting an AI chatbot in 2026. Custom builds cost $100K–$500K and take 3–9 months but offer full control. SaaS solutions deploy in days but create vendor lock-in and limited customization. The 'adapt' model—using configurable platforms like Rasa, Dialogflow CX, or Cognigy—deploys in 2–4 weeks with moderate-to-deep customization, costing $242K–$581K over three years. The adapt approach is positioned as the practical middle ground, especially for e-commerce teams needing speed without sacrificing control over product discovery flows, integrations, and business logic.
