Products, side by side

Algorithmic pairing — assembled from recorded fields, not hand-checked

Arize AI

Platform

Arize AXPlatform

AI observability platform that traces, evaluates and monitors machine-learning and LLM applications in production, surfacing issues and root causes.

Elastic

Platform

Elastic AI AssistantPlatform

A conversational assistant embedded in Kibana that answers natural-language questions against a customer's own indexed data across Elastic's Observability, Security and Search solutions.

No counterpart

Arize AI sells these in a stack layer with no product recorded for Elastic yet — nothing on the other side to compare them against.

AI agent

AlyxAI agent

AI engineering agent built into Arize AX that reads a project's traces, prompts, datasets and evals and acts on them — investigating issues, improving prompts and running evaluations from a full-page or side-chat surface whose context carries across pages.

Developer tool

Arize PhoenixDeveloper tool

Open-source platform for tracing, evaluating and experimenting with LLM and agent applications, run locally, via Docker/Kubernetes, or as free Phoenix Cloud instances.

Infrastructure service

Arize Database (adb)Infrastructure service

An AI-native datastore (built on Apache Iceberg) that unifies observability and evaluation data in open formats for zero-copy access across the AI/data stack.

Elastic sells these in a stack layer with no product recorded for Arize AI yet — nothing on the other side to compare them against.

Application

Elastic AI SOC EngineApplication

An AI security-operations layer that correlates alerts from a customer's existing security tools, prioritizes threats and guides response workflows without replacing their SIEM.

Elastic AIOpsApplication

GenAI- and ML-driven capability inside Elastic Observability that automatically detects, diagnoses and helps resolve operational issues, providing recommended actions for SREs.

Elastic LLM ObservabilityApplication

Monitoring capability inside Elastic Observability for generative-AI and agentic applications: performance, cost control, guardrail tracking and reliability for GenAI workloads.

Elastic SecurityApplication

Agentic security-operations platform unifying SIEM, XDR and native automation, with autonomous agents handling detection-to-response workflows and purpose-built AI skills for threat hunting, alert analysis and detection engineering; supports multiple LLMs including on-premises models.

Agent platform

Elastic Agent BuilderAgent platform

A builder for custom AI agents that answer questions and take actions over data indexed in Elasticsearch, using configurable tools, skills and prompts.

Elastic WorkflowsAgent platform

An automation engine that runs both scripted steps and AI agents which reason through investigations and execute response actions against data in Elasticsearch.

Model API

Elastic Inference ServiceModel API

Hosted inference endpoint that runs Elastic-managed LLMs, the ELSER sparse-embedding model and third-party embedding models for ingest, search and chat without provisioning ML nodes in a customer's own Elasticsearch deployment.
