We're two engineers in Berlin who kept hitting the same wall building AI workflows. Every time we needed agents, document retrieval, approval steps, and observability in the same flow, we ended up gluing five tools together.
So we built Heym, launching Tuesday. Self-hosted, source-available, visual canvas.
One thing we're genuinely still thinking about: what's the right balance between no-code accessibility and the depth that technical teams actually need? We've leaned technical and curious what this community thinks.
Build AI workflow automations visually, with no coding required. Heym supports multi-agent orchestration, RAG pipelines, and MCP, plus a powerful AI builder for faster creation.
Heym is a source-available, self-hosted AI workflow automation platform. It offers a visual canvas, many node types, multi-agent orchestration, RAG capabilities, HITL approvals, an MCP server/client, full LLM traces, and a portal that turns any workflow into a public chat UI. Ready to setup with no vendor lock-in.
