Heym

Heym is a source-available platform for building and self-hosting multi-agent workflows. Developers can visually construct agent systems, integrate custom data and tools, incorporate coding agents, and embed human-in-the-loop approval gates. The platform provides native observability with built-in tracing, cost tracking, latency metrics, and evaluations while allowing teams to ship workflows as APIs, portals, or MCP tools.
