What Heym is
Heym is infrastructure for building, running, and governing AI agents and workflows in production. Teams can create workflows on a visual canvas or describe them in natural language or voice for an AI assistant to generate. An orchestrator can delegate work to named sub-agents and sub-workflows, nested up to five levels. Its retrieval pipeline supports document uploads and semantic search using managed Qdrant or built-in Postgres with pgvector, with optional Cohere reranking. Human-review checkpoints can pause a workflow so a reviewer can accept, edit, or refuse before it resumes. Execution traces capture prompts, responses, tool calls, timing, and token use, alongside built-in evaluation features. Listed integrations include OpenAI, Anthropic, Google Gemini, Slack, Discord, Gmail, Outlook, GitHub, Jira, Telegram, Notion, Qdrant, Redis, RabbitMQ, Google Sheets, and MCP. Heym can be self-hosted with Docker Compose or Kubernetes. The source-available software is free to use, modify, and distribute, but not to resell as a paid service. Community help is available through Discord; support packages and enterprise engagements may be paid.
