Heym is an agentic AI workflow automation platform with a visual, low-code editor. Describe a workflow in natural language and the assistant builds it for you, or wire it yourself from a deep library of built-in nodes and integrations. It supports LLM nodes for text generation and vision, Agent nodes with tool calling and Python tools, RAG for semantic search over Qdrant or built-in Postgres (pgvector), MCP client and server integration, human-in-the-loop approval checkpoints, content guardrails, parallel DAG execution, a skills system for portable agent capabilities, Playwright browser automation with auto-heal, and integrations with Telegram bots, Slack, IMAP inboxes, outbound WebSocket streams, email, Redis, RabbitMQ, Grist, and any HTTP API. Heym is source-available and fully self-hosted, so your data and automations stay on infrastructure you control, from the first prototype to production, with tracing and evals built in. Self-host with Docker Compose or Kubernetes on your own infrastructure.

Heym is a source-available AI-native workflow automation platform that lets you build, visualize, and run intelligent pipelines without writing code. Using a drag-and-drop canvas, you connect a broad library of node types across seven categories — triggers, AI, logic, data, integrations, automation, and utilities — into production-grade workflows that run on your own infrastructure.
Every workflow is a directed acyclic graph (DAG) that Heym compiles, validates, and executes in parallel where dependencies allow, giving you maximum throughput without manual parallelism boilerplate.
Explore the platform overview, feature deep dives, node reference, documentation hub, use cases, enterprise options, and community resources from the links in the site footer.
MCP integration works in both directions. As an MCP client, Agent nodes connect to any external MCP server and gain access to all tools it exposes. Heym automatically discovers available tools on connection and presents them in the agent configuration panel.
As an MCP server, Heym exposes all published workflows as callable tools over the MCP protocol. Claude Desktop, Cursor, VS Code extensions, and other MCP-compatible clients can invoke your workflows directly from their native interfaces.
The skills system enables portable, reusable capability bundles for Agent nodes. A skill is a zip archive or Markdown file containing a SKILL.md instruction document and optional Python tool files. Dragging a skill onto an Agent node extends that agent’s system context and toolbox without modifying the node configuration.
Skills can define custom tool schemas, persistent memory structures, and multi-step reasoning templates. Agent nodes include an AI Skill Builder modal for drafting and revising skills with live previews. The same skill can be shared across multiple agents and workflows for consistent behavior across an organization.
Join the Heym Discord community to share workflows, report issues, and collaborate with other builders. Tutorial videos walk through canvas basics, agent configuration, RAG setup, and deployment patterns.
Community templates and blog posts demonstrate real production patterns — from MCP tool servers to evaluation-driven prompt iteration. Sharing workflows publicly helps other teams adopt guardrails, tracing, and human review patterns that are easy to skip in early prototypes.
Contributing back to the open-source repository improves documentation, adds node types, and hardens executor edge cases. Whether you file a bug with a minimal reproduction or ship a pull request for a new integration node, the community benefits from shared execution semantics tested across diverse deployments.
