| Description | 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. | Windsurf by Codeium is the agentic IDE that keeps developers in flow. Its Cascade agent can plan, implement, debug, and iterate on multi-file changes autonomously — going beyond autocomplete to actually understand your entire codebase and take action. |
