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.
Learn to code free with hands-on lessons and instant playgrounds
Short, practice-first coding lessons that run directly in your browser, so you can start learning without installing a compiler or development environment.
Dedicated playgrounds for Python, JavaScript, C, C++, Java, SQL, React, Go, Swift and many other languages let you test snippets and experiment immediately after each lesson.
Structured curricula such as Software Engineer, Frontend, Full Stack, Backend, Data Analyst, Data Scientist, DevOps and game development bundle the skills employers actually ask for.
Streak-style daily coding challenges and progress tracking help learners build a consistent habit and stay motivated between longer courses.

SpecialistTeaches computer science and logic through visual interactive puzzles and an AI tutor, but lacks traditional text-editor coding playgrounds.

SpecialistFocuses on hands-on browser-based Linux and DevOps labs with AI guidance, rather than general multi-language programming fundamentals.

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

SpecialistKhan Academy's AI tutor and teaching assistant for guided, Socratic learning

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.
SpecialistYour personal AI tutor — generate a course on anything in seconds

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.

Free / Open-sourceAgent observability, evals and governance for AI platform teams

SpecialistStronger focus on compliance enforcement and AI governance, but less specialized for deep developer tracing workflows.
