smithy-aws-core
Core Smithy components for AWS services and protocols.
Decision gist · record as of 2026-08-14
Yes, if you are actively generating Smithy-based Python clients and accept pre-alpha instability. The package is actively maintained, has low install friction, and carries no known vulnerabilities. However, do not use in production systems—the documentation explicitly warns that interfaces are unstable and several features remain unimplemented. Install only when you are part of the Smithy code generation workflow.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires Python 3.12 or later.
- This package is a runtime dependency for code generated by the Smithy Python code generator; it is not typically instantiated directly but rather used by generated client code.
- Active maintenance with a release within the last day.

What it is and what it does
smithy-aws-core is a low-level Python library that provides foundational runtime components for async service clients generated from Smithy service definitions. It supplies protocol handlers, core interfaces, and utilities that generated clients depend on, working alongside the Smithy code generator. The package is part of the broader Smithy Python ecosystem.
The library targets developers generating Python clients from Smithy models—either full service clients or type definitions for shapes. It currently supports the restJson1 protocol and depends on aws-sdk-signers, smithy-core, and smithy-http. The package requires Python 3.12 or later and explicitly marks all interfaces as subject to change, reflecting its pre-alpha development stage.
Use it for
- Generate async Python service clients from Smithy models for experimental or internal services
- Build type-safe Python classes for Smithy shape definitions without generating full clients
- Prototype REST/JSON service clients before production deployment
- Integrate Smithy-defined services into Python applications using async/await patterns

Before you install
Active maintenance with a release within the last day. Low install friction with only three runtime dependencies (aws-sdk-signers, smithy-core, smithy-http). Pre-alpha status means interfaces remain unstable.
Requires Python 3.12 or later. This package is a runtime dependency for code generated by the Smithy Python code generator; it is not typically instantiated directly but rather used by generated client code.
