It uses pydantic for automatic input/output schema inference and validation. The library provides `/invoke`, `/batch`, and `/stream` endpoints for efficient concurrent request handling, plus a `/stream_log` endpoint for intermediate step visibility and a web playground for testing.\n\nThe package is designed for simple runnables and well-known LangChain primitives. It includes a Python client SDK to call deployed runnables as if they were local objects, optional tracing integration with LangSmith, and automatic API documentation. However, the repository is now archived and no longer accepting new features\u2014the maintainers recommend LangGraph Platform for new projects.","worth_installing":"No\u2014not for new projects. The repository is archived and abandoned; maintainers explicitly recommend LangGraph Platform instead. Existing LangServe deployments may continue to receive bug fixes, but the lack of active maintenance, unclear licensing, and explicit deprecation guidance make this unsuitable for new development."},"id":"langserve","links":{"html":"https://skillfed.io/packages/langserve","md":"https://skillfed.io/packages/langserve.md","pypi":"https://pypi.org/project/langserve/"},"maintenance":{"status":"abandoned"},"meta":{"latest_release":"2025-10-17","license_spdx":null,"license_treatment":"unclear","name":"langserve","python_support":"supports_current","summary":null},"popularity":{"monthly_downloads":527184,"position":6170,"tier":"top_15000"},"security":{"n_vulnerabilities":0},"version":"0.3.3"}
