You write your API specification once in Stone's language, then use backends (code generators) to automatically produce client libraries and server stubs in your choice of target languages. The package includes builtin backends for Javascript, Python, Obj-C, Swift, and Typescript, and provides a Python interface for writing custom backends to generate code for any target.\n\nThe core problem Stone solves is decoupling API specifications from SDK implementations\u2014instead of maintaining separate SDKs in multiple languages that drift out of sync, you maintain a single spec and regenerate all client libraries from it. It also provides a single source of truth for API documentation and enforces consistency across your API design. Stone makes no assumptions about the protocol layer or RPC framework, focusing purely on data type and endpoint specification.","worth_installing":"Yes, if you are building or maintaining an API that needs to be consumed by clients in multiple programming languages. Stone is production-grade, actively maintained, has no known vulnerabilities, and solves a real problem at scale. Install friction is minimal. If you only need SDKs in one or two languages or are not responsible for maintaining API consistency across multiple implementations, it may be overkill."},"id":"stone","links":{"html":"https://skillfed.io/packages/stone","md":"https://skillfed.io/packages/stone.md","pypi":"https://pypi.org/project/stone/"},"maintenance":{"status":"active"},"meta":{"latest_release":"2026-08-03","license_spdx":"MIT","license_treatment":"permissive","name":"stone","python_support":"supports_current","summary":"Stone is an interface description language (IDL) for APIs."},"popularity":{"monthly_downloads":2273028,"position":3176,"tier":"top_5000"},"security":{"n_vulnerabilities":0},"version":"3.5.4"}
