Botpress

Botpress is an all-in-one platform for building and deploying LLM-powered AI agents, with an open-source core that supports self-hosting plus a managed cloud product. It offers a visual studio, knowledge bases and multi-channel deployment, and bills AI model usage separately from plan fees on the cloud.

Botpress is a platform for building AI agents powered by large language models. It provides a visual studio for designing conversation logic, a knowledge base for grounding answers, and integrations to deploy agents across channels such as web, WhatsApp, Slack and more. Originally a well-known open-source chatbot framework, Botpress pivoted in 2023 into an all-in-one cloud platform for LLM-based agents, while keeping its open-source server as a self-hosting on-ramp. The open-source core means technically capable teams can self-host, inspect and extend the platform, while the Botpress Cloud product handles hosting, scaling and advanced integrations for those who prefer a managed service. Pricing on the cloud side now bills AI model usage (AI Spend) separately from plan fees, so teams should model both message volume and LLM costs. Botpress is a venture-backed company that has raised roughly $40 million across several rounds, including a $25 million Series B in 2025 led by FRAMEWORK at a reported $120 million post-money valuation. It suits developers and teams that want flexibility, an option to self-host, and a path to a managed cloud as they scale, though the combination of plan fees, message overages and separate AI Spend makes cost planning important.
