Spec score 7.8 #16 of 30 in AI Workflow Automation Software

What it is

Heym is infrastructure for building, running, and governing AI agents and workflows in production. Workflows can be assembled on a visual canvas or described by text or voice for generation by its AI assistant. An orchestrator delegates to named sub-agents and sub-workflows across as many as five nesting levels. Retrieval supports managed Qdrant or built-in Postgres with pgvector, document uploads, semantic search, and optional Cohere reranking. Human-review checkpoints pause runs so a reviewer can accept, edit, or refuse before continuation. Execution traces record prompts, responses, tool calls, timing, and token use, with 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 is self-hostable with Docker Compose or Kubernetes, and describes encrypted credentials plus JWT authentication.
