About Heym

What the tool does and who it's for

Heym is a source-available platform for building and running agentic systems on your own infrastructure. Build multi-agent workflows visually, connect your data and tools, bring in coding agents like Codex and OpenCode, and add human approval where it matters. See exactly how every run performs with built-in traces, costs, latency, and evals. Self-host Heym, use your own models and credentials, and ship workflows as portals, APIs, or MCP tools.

Key capabilities

Visual Multi-Agent Workflow Builder: Design complex multi-agent orchestrations visually on a canvas.
Self-Hosted Infrastructure: Run platforms on your own hardware, using your own models and credentials.
Coding Agent Integration: Integrate coding agents like Codex and OpenCode directly into workflows.
Human-in-the-Loop (HITL): Add mandatory human review and approval gates where critical decisions occur.
Comprehensive Observability: Monitor run performance with real-time traces, execution costs, latency, and evaluations.
Flexible Deployment Options: Ship and expose completed workflows as portals, REST APIs, or MCP tools.
