Agent observability, evaluation, and continuous improvement for production AI
Capture spans, traces, and sessions across agents and LLM calls using OpenInference conventions built on OpenTelemetry, so instrumentation stays portable.
Run evaluations at span, trace, and session level to grade retrieval quality, tool use, and final answers across large production datasets.
An in-product agent that inspects traces, diagnoses likely root causes, and proposes fixes that engineers can review before shipping.
Self-host the leading open-source tracing and eval tool when you need to keep trace data inside your own infrastructure.

Targeted research audiences with AI-verified data quality
Recruit from 100+ consumer segments and industries, from first-time homebuyers to niche professional groups, based on detailed profiling.
Connect to custom audiences in real time through the Audience API and route qualified participants straight into your own research programming tools.
AI verification of participant responses removes poor actors and protects data integrity before insights reach decision-makers.
Support webcam studies, emotional AI research, surveys, and concept testing, with the flexibility to use your own tools or a third-party platform.

#1
Automates qualitative customer research by moderating live user interviews at scale and synthesizing insights into actionable reports.
#2Runs AI-moderated qualitative interviews and automated research studies at scale, replacing traditional panel surveys with interactive conversations.

Excels at experiment tracking and model registry workflows, but is less purpose-built for real-time LLM production observability.

Captures video-based consumer surveys and interviews, using AI to automatically analyze emotional sentiment and thematic feedback.

SpecialistSources verified B2B professionals and healthcare experts for specialized respondent recruitment, though with less automated consumer panel volume.


Free / Open-sourceIncludes integrated guardrails and simulation tools, but is less mature for large-scale enterprise production telemetry monitoring.

Free / Open-sourceFeatures strong testing and prompt evaluation tools, though its monitoring interface is less oriented towards massive telemetry streams.

Focuses heavily on prompt management and versioning control, whereas Arize prioritizes end-to-end tracing and ML observability.

Offers comprehensive LLM evaluation and unit testing via DeepEval, but lacks Arize's deep production monitoring infrastructure.

SpecialistConducts voice and chat-based qualitative customer interviews, automatically analyzing transcripts into comprehensive market research reports.
