Datadog LLM vs Maxim AI
Overview
Datadog's LLM Observability extends its industry-leading APM platform to AI applications. It provides end-to-end tracing from LLM calls to infrastructure metrics, prompt and completion tracking, cost analysis, and quality evaluation—all integrated with Datadog's existing monitoring, logging, and alerting stack. Ideal for enterprises already using Datadog who want unified observability across traditional and AI workloads.
Maxim AI is an end-to-end LLM evaluation and observability platform aimed at engineering teams building and shipping AI agents and copilots. It combines tracing, evaluators, a prompt playground, and human-in-the-loop review workflows, and offers both managed cloud and self-hosted deployment.
