Heym

Heym is a self-hosted platform for building and running agentic AI systems. Users compose workflows visually using a low-code editor, describe them in natural language for AI generation, or wire them from built-in nodes and integrations. It supports LLM and agent nodes with tool calling, RAG pipelines with Qdrant or Postgres, MCP integration, human-in-the-loop checkpoints, parallel execution, browser automation, and connections to Slack, email, GitHub, Jira, and HTTP APIs.

Designed for AI, platform, and automation teams, Heym provides full observability with execution traces, token counts, latency metrics, and cost tracking. The platform is source-available and fully self-hosted via Docker or Kubernetes, keeping data and automations on your own infrastructure from prototype through production.
