Onyx's bet is a single owned retrieval layer: index once, let every agent query the same permission-aware index. The honest read: the free MIT tier covers the core retrieval and chat stack, which is most of what a lean team needs, but enterprise-grade access control and white-labeling sit behind a paid tier — worth checking that split against your actual compliance requirements before standardizing on it."
