Description

Scalebrowser provides isolated browser profiles with persistent identity for AI agents, letting each agent operate with its own consistent cookies, sessions, and fingerprint across runs instead of a fresh, identity-less browser context every time. It is aimed at teams building browser-using AI agents at scale who need each agent to behave like a consistent, distinct user rather than triggering anti-bot defenses designed to catch identical, disposable sessions.

LangWatch is an open-source, framework-agnostic platform for testing, evaluating, observing, and optimizing AI agents and LLM applications. It uses simulation-based testing with real-user text and voice conversations, LLM-as-a-judge evaluations, red teaming, and OpenTelemetry-native observability to catch issues and prevent regressions. It supports collaboration between technical and non-technical teams and can be deployed as cloud, self-hosted, or hybrid.
