# LangWatch

A platform for testing, evaluating, and observing LLM-powered agents through simulation, scoring, and trace analysis.

**Route:** surfaced by the AI Development and Deployment Infrastructure lane's de-branded queries → substitute to vercel.com.

**Why it's on the map:** A buyer evaluating the anchor for deploying and scaling AI agents could use LangWatch instead to test and validate those agents before production, making the anchor's deployment pipeline unnecessary for the testing and evaluation phase.

**Receipts** (verbatim from its page this run):

> AI Agent Testing and Evaluation

> Simulation-based AI agent testing and evaluation that turns unpredictable agents into reliable production systems

> Trace every agent step and monitor cost and latency with full production visibility
