Why this ring

Use in production without hesitation.

Open-source, self-host trivial, dataset management built-in. Boa escolha pra empresas que precisam de tracing on-prem (compliance, IP). Comunidade ativa, releases frequentes. Em workflows que não precisam de self-host, Braintrust tem DX melhor; em ambientes restritos, Langfuse vence.
