Domain Rating by Ahrefs, checked 3 Oct 2026, changed 3 Oct 2026.
Platform for simulation-based testing, evaluation, and observability of AI agents with governance and security controls for production deployment.
Billing combines seats and usage. Growth is €29 per core-seat per month; on top you pay for usage at €5 per 100k events beyond the 200k monthly allowance, and €3 per GB only if you retain data beyond the included 30 days. Payment can be by card, or by invoice and AWS/Azure/GCP marketplace on Enterprise.
Events measure the work AI applications perform in LangWatch. Every LLM call, tool call, retrieval, evaluation, or simulation step counts as an event. Most AI applications generate multiple events during a single user interaction, such as an agent that retrieves information, calls an LLM, uses tools, and runs quality evaluations.

No. The Developer plan is free forever; sign up and start sending events with no card required.
Yes, upgrade, downgrade or cancel whenever you like.
