Datadog LLM observability alternatives (2026): Better tools for AI quality
Blog post from Braintrust
Braintrust is highlighted as the leading alternative to Datadog for teams aiming to improve AI output quality by integrating evaluations, CI/CD quality gates, and production feedback loops into a unified workflow. While Datadog is adept at monitoring LLM systems through dashboards that track latency, error rates, and token costs, it lacks the capacity for systematic output improvement and regression prevention. Braintrust, in contrast, emphasizes evaluation as a core component of the development process, allowing production traces to be transformed into test cases and evaluation results to influence pull request decisions. It supports offline and online evaluations, custom scoring types, and collaboration through shared playgrounds, with a pricing model that scales with data usage rather than user count. Other top contenders include LangSmith for those invested in LangChain, Galileo for real-time guardrails, W&B Weave for Weights & Biases users, and Fiddler AI for enterprises focused on governance and compliance, each catering to specific organizational needs and ecosystems.
