It supports popular frameworks like LangChain, LlamaIndex, and OpenAI SDK, making it easy to integrate into existing workflows. Langtrace offers both a hosted cloud version and a self-hosted option, catering to teams with varying security and compliance needs. Its core capabilities include real-time monitoring, cost analysis, and performance insights, helping teams improve response quality and reduce operational overhead. The platform is ideal for AI engineers, ML ops teams, and product developers who need visibility into their LLM applications.
