You think you know which bot platform to pick until the first production pilot exposes brittle intent models, messy handoffs, and channel policy surprises. Working across different tech companies, we have seen teams waste months on issues that better tools solve out of the box. From our experience in the startup ecosystem, three technical choices separate quick wins from rework: a dialogue manager that handles interruptions, strong voice and telephony connectors for IVR handoffs, and an analytics loop that drives training data fixes. The market is moving fast, and adoption pressure is rising, which is why this guide focuses on proven platforms. A 2024 survey found that 85 percent of service leaders planned to explore or pilot customer-facing conversational GenAI in 2025, a signal that budgets are real and timelines are short, according to a Gartner press release.
The final five platforms below consistently delivered on orchestration, deployment flexibility, and measurable outcomes. For market context, the global conversational AI market was about 11.6 billion dollars in 2024 and is projected to reach 41.4 billion dollars by 2030, based on Grand View Research's 2025 report. In this guide, you will learn when to choose each platform, what it does well, where reviewers report friction, and how pricing is structured where public information exists.
Rasa Pro
Commercial, pro-code framework plus optional no-code UI for building production AI assistants with granular control and enterprise add-ons. Known for on-prem and private cloud deployments, with telemetry and observability options for regulated environments.

- Pricing: Enterprise pricing is not publicly available. For SMBs, Haptik's Interakt initiative has India pricing starting around Rs 10,000, as covered by the Times of India. Haptik has operated under Jio since a 2019 acquisition, which you should note for vendor due diligence, per TechCrunch's deal report.
Gupshup
Conversational engagement and messaging platform with multichannel bot building and generative automation, widely used for WhatsApp, SMS, and marketing flows.
