LangWatch Scenario - Agent Simulations

LangWatch Scenario - Agent Simulations

Agentic testing for agentic codebases

Overview

What it is

Open-source testing platform for AI agents. Run simulations, catch regressions, and ship autonomous agents with confidence. Built for developers who treat AI like software. Agent simulations are the new unit tests

Intent

I need it when

Validate multi-turn conversations and complex agentic workflows in controlled environments

Agent Simulations enables testing of multi-step agent behavior, multi-turn conversations, and tool usage patterns through realistic scenario-based simulations, ensuring agents handle complex workflows correctly.

Create reusable test datasets and benchmarks from production traces

Agent Simulations work with dataset management features to convert production traces into reusable test cases and golden datasets that power experiments and regression testing across agent iterations.

Measure impact of agent changes and prevent regressions across updates

Simulations integrate with batch tests and experiments to track the impact of every change to prompts, models, and agent pipelines, providing structured regression testing before deployment.

Test AI agents before production deployment to catch failures and regressions early

Agent Simulations runs thousands of synthetic conversations across scenarios, languages, and edge cases to validate agent behavior before release, preventing production failures and quality degradation from prompt or model changes.

Drop

Not a fit when

  • Teams requiring on-premises deployment without custom negotiation, as self-hosted is only available on Enterprise plan
  • Organizations with minimal AI agent testing needs and no budget for paid tiers, as free plan limits to 3 scenarios and 3 simulations
  • Companies needing real-time production monitoring without any testing/evaluation component, as Agent Simulations is pre-production focused
  • Teams using non-standard AI frameworks not listed in LangWatch integrations (Python SDK, JS/TS SDK, OpenTelemetry, LangChain, DSPy, etc.)
  • Organizations requiring guaranteed uptime SLA or premium support without Enterprise contract
