About Hexabot

Hexabot is a self-hosted, open-source AI workflow automation platform that enables teams to build AI agents, agentic workflows, and business automation with complete control over data and infrastructure. It offers a no-code visual workflow builder alongside YAML-based portability, supports multi-channel deployment (web, messaging, social, and custom channels), and integrates with LLMs, NLU, RAG, and MCP. Features include human-in-the-loop review points, memory, scheduled/event triggers, and reusable actions with typed contracts. Hexabot is source-available under the FCL-1.0-ALv2 license and does not bill by message volume or workflow executions. Pricing starts with a free Community plan (10 workflows, 1 user) and scales through license-key-based paid plans.
