For companies that want AI apps fast without writing everything: visual orchestration, RAG, dozens of model providers, access control — all self-hostable. The default base for an SME's AI proof-of-concept.
Laojin's advice
Mind the two-layer data boundary: app data can stay on your servers, but model calls still leave for external APIs — audit that separately for compliance. Keep canvases to a dozen nodes; beyond that, maintaining visual branches is worse than going back to code.
