Full review

Botpress is an all-in-one platform for building AI agents and chatbots powered by current LLMs, pairing a visual Studio with code-based tools, custom knowledge sources, and third-party integrations.

It has repositioned from scripted chatbots to autonomous agents, lets builders start free and pay for usage as agents grow, and added a $25M Series B in 2025 backed by HubSpot Ventures and others.

It suits developers and teams that want flexibility and control, with the reminder that capable agents still require careful design and that costs scale with usage.
