Products, side by side

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

Arize AI

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.

Platform

Arize AXPlatform

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

Labelbox

Developer tool

Labelbox FoundryDeveloper tool

Foundry runs third-party foundation models over data already in Labelbox to pre-label and enrich image, text and document datasets without code, routing the predictions to human review; billed as inference cost per model run plus Labelbox Units.

Platform

HorizonPlatform

Horizon supplies RL training gyms and evaluations for reasoning, tool use and computer use, using WorldSim to simulate enterprise environments such as GitLab, Jira, CRM, email and chat and to produce calibrated reward and preference signals for post-training.

No counterpart

Arize AI sells these in a stack layer with no product recorded for Labelbox 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.

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.

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