## Arize AI

Arize is an AI engineering platform built for teams that run generative AI in production. It is split into two products: Arize AX, a managed environment for agent observability, evaluation, and experimentation, and Phoenix, an open-source tracing and evaluation library that teams can self-host when they need full data control. Both rely on OpenInference, the open-source semantic convention for generative AI tracing that the Arize team founded and that is built on OpenTelemetry.

The workflow follows three questions. Observe answers what an agent actually did by capturing every span, trace, and session; Evaluate answers whether quality is improving or regressing using span-level, trace-level, and session-level evals; Learn answers whether a proposed change will help by letting teams test prompts and harnesses before rollout. A datastore for GenAI traces (ADB) keeps data in open formats that connect to warehouses such as BigQuery, Databricks, and Snowflake, and an in-app AI engineering agent named Alyx surfaces issues and drafts review-ready fixes.

The platform integrates with dozens of models, frameworks, and tools, including OpenAI, Anthropic, Google, Amazon Bedrock, LangChain, LangGraph, LlamaIndex, CrewAI, and DSPy. Arize publishes compliance certifications including SOC 2 Type II, ISO 27001, PCI DSS, HIPAA, and GDPR, and supports cloud, hybrid, and self-hosted deployment.

**Pricing & Plans:** Arize uses a paid model with a free entry point: teams can start free or book a demo, while enterprise-scale usage, deployment options, and support are quoted through a contact-sales process. The open-source Phoenix project is free to self-host.

- **End-to-end tracing:** Capture spans, traces, and sessions across agents and LLM calls using OpenInference conventions built on OpenTelemetry, so instrumentation stays portable.
- **Scalable evaluation framework:** Run evaluations at span, trace, and session level to grade retrieval quality, tool use, and final answers across large production datasets.
- **Alyx AI engineering agent:** An in-product agent that inspects traces, diagnoses likely root causes, and proposes fixes that engineers can review before shipping.
- **Phoenix open-source toolkit:** Self-host the leading open-source tracing and eval tool when you need to keep trace data inside your own infrastructure.
- **Warehouse-native trace storage:** ADB stores traces in open formats that connect natively to BigQuery, Databricks, or Snowflake for joint analytics with business data.

**Strengths:** Covers the full loop of observe, evaluate, and improve rather than stopping at dashboards; Backed by OpenInference and OpenTelemetry standards, limiting vendor lock-in on trace formats; Strong enterprise posture with SOC 2, ISO 27001, HIPAA, and GDPR coverage plus self-hosting options; Integrates with a very wide set of models, frameworks, and agent SDKs

**Limitations:** Self-serve pricing is not published, so cost requires a sales conversation; The breadth of features can be overwhelming for small teams shipping their first LLM feature; Full value depends on disciplined instrumentation across the whole application

## Datadog

Datadog began as a hosted infrastructure-monitoring service and has grown into a broad platform spanning observability, application security, digital experience and service management. Its core promise is a single, consistent data model: metrics from agents and cloud integrations, distributed traces from instrumented services, logs from collectors, real user monitoring from browsers and mobile apps, and synthetic checks from managed locations all land in the same graph, so a spike in latency can be tied to a specific deploy, container, database query or error log without switching consoles.

On top of that foundation, Datadog layers AI-assisted workflows. Bits AI acts as an investigation and chat assistant, an agent builder lets teams compose automation, and dedicated AI Observability and LLM monitoring views track model latency, cost, token usage and agent traces. Security surfaces such as Cloud SIEM, Cloud Security Posture Management, vulnerability management and code scanning share the same telemetry, and software-delivery features cover CI visibility, test optimization, feature flags and DORA metrics.

Datadog is aimed at teams running cloud-native, multi-cloud and Kubernetes-heavy estates, from startups to large enterprises. It is a paid, usage-metered service with a free trial and generous free allowances on many individual products, and it ships official SDKs, an MCP server, OpenTelemetry support and an integrations directory covering AWS, Azure, Google Cloud, databases, queues and popular frameworks.

**Pricing & Plans:** Usage-based SaaS pricing. New customers get a free trial, and many individual products include free tiers or allowances (for example, a handful of free hosts, limited custom metrics or log ingestion credits). Beyond that you pay per host, per ingested log volume, per indexed span, per monitored synthetic test and per security seat, with annual commitments typically discounted. Enterprise and consolidated-bundle plans are quoted by sales.

- **Unified metrics, traces and logs:** Agents, cloud integrations and OpenTelemetry collectors feed one platform where metrics, distributed traces, profiles and logs can be pivoted between without context switching.
- **AI-assisted investigation:** Bits AI, an agent builder and LLM/AI-agent observability help teams triage alerts, explain anomalies and monitor model latency, token spend and agent traces.
- **Security in the same data model:** Cloud SIEM, cloud security posture management, vulnerability management, workload protection and code scanning correlate threat signals with the telemetry you already collect.
- **Digital experience and delivery:** Real user monitoring, session replay, product analytics, synthetic and mobile testing sit alongside CI visibility, test optimization, feature flags and DORA metrics.
- **Alerting, SLOs and automation:** Metric, log and trace monitors, service-level objectives, event management, on-call schedules and workflow automation turn signals into coordinated action.

**Strengths:** Very broad product coverage from infrastructure, APM and logs through to security, RUM and software delivery; Strong integrations and OpenTelemetry support across clouds, runtimes and languages; Shared data model makes cross-signal correlation practical in one interface; Reliable alerting, dashboards, SLOs and collaboration features for on-call teams

**Limitations:** Costs can climb quickly because pricing is granular per host, per log volume and per span; The breadth of the catalogue means onboarding and configuration take real effort; Some advanced AI and security modules require separate purchases, which complicates budgeting
