It hooks into langchain-core to intercept calls across all LangChain packages (langchain-openai, langchain-anthropic, langchain-google-vertexai, etc.) and works with both the modern LangChain 1.x agent framework and the legacy LangChain Classic chains API.\n\nOnce instrumented, every LangChain operation\u2014agent steps, tool calls, LLM invocations, prompt templates\u2014generates a span that can be viewed in a web dashboard for debugging, performance analysis, and tracing AI application behavior. It requires an OpenTelemetry exporter and collector endpoint to function; Arize Phoenix is the recommended local option.","worth_installing":"Yes, if you are building or maintaining LangChain applications and need visibility into execution. The package is actively maintained, has no known vulnerabilities, installs with low friction, and integrates seamlessly with standard observability infrastructure. The Apache-2.0 license poses no barrier. Install it alongside an OpenTelemetry collector (Arize Phoenix is free and local) to enable immediate tracing."},"id":"openinference-instrumentation-langchain","links":{"html":"https://skillfed.io/packages/openinference-instrumentation-langchain","md":"https://skillfed.io/packages/openinference-instrumentation-langchain.md","pypi":"https://pypi.org/project/openinference-instrumentation-langchain/"},"maintenance":{"status":"active"},"meta":{"latest_release":"2026-08-07","license_spdx":"Apache-2.0","license_treatment":"permissive","name":"openinference-instrumentation-langchain","python_support":"supports_current","summary":"OpenInference LangChain Instrumentation"},"popularity":{"monthly_downloads":3470274,"position":2612,"tier":"top_5000"},"security":{"n_vulnerabilities":0},"version":"0.1.70"}
