How LangWatch compares to Arize
Agent simulation testing
Scenario-based testing framework that simulates real user interactions to validate complex agent behaviors and multi-step workflows before they reach production environments.
LLM-native architecture
Purpose-built for LLM applications with native support for conversation flows, prompt engineering, and agent-specific evaluation patterns.
Flexible collaboration model
Friendly platform UI for domain experts to create scenarios while providing powerful APIs and SDKs for developers to build complex workflows.
Automated prompt optimization
DSPy-powered automation that iteratively improves prompt performance through systematic generation and evaluation of variants using optimization algorithms.
Input/output evaluation focus
Traditional evaluation methodology using input/output pairs and statistical analysis for model performance assessment and drift detection across production systems.
ML-first platform with LLM features
Traditional ML monitoring platform extended to support LLM use cases, maintaining focus on statistical analysis and model drift detection.
Technical team focus
Designed primarily for ML engineers and data scientists with advanced statistical analysis tools requiring technical expertise.
Manual prompt management
Standard prompt versioning and tracking capabilities with human-driven optimization processes that require manual testing and performance validation across multiple deployment environments and use cases.
