mypy-boto3-support

What it is and what it does

This package is a type stub library that adds complete type annotations for the AWS boto3 Support service. It is generated automatically from boto3 1.43.28 using mypy-boto3-builder 8.12.0 and works with mypy, pyright, VSCode Pylance, PyCharm, Emacs, Sublime Text, and other type-aware development tools.

When installed, it enables static type checking and IDE autocompletion for boto3 Support client calls without requiring explicit type annotations in your code. The package is designed to be used alongside boto3 itself and depends only on typing-extensions. It is classified as stubs-only and carries no runtime behavior beyond providing type information to checkers and IDEs.

Use it for:

• Enable IDE autocompletion and type hints when writing boto3 Support service code in VSCode with Pylance or PyCharm.
• Catch type errors in boto3 Support API calls during development using mypy or pyright before runtime.
• Provide explicit type annotations for SupportClient, paginators, and service resources in large codebases.
• Support Emacs or Sublime Text development workflows with LSP-based type checking via pyright.
• Avoid production dependencies by importing stubs only within TYPE_CHECKING blocks while maintaining type safety.

Worth the install?

AI-flagged interpretation of the facts on this page — verify before relying

Provides type annotations and IDE autocompletion for the boto3 Support service, enabling static type checking with mypy, pyright, and other tools.

Yes. This is a low-friction, actively maintained type stub package with no known vulnerabilities and a permissive MIT license. Install it if you use boto3 Support and want IDE autocompletion or static type checking. The single dependency (typing-extensions) is widely available. Note that PyCharm users may experience performance issues with Literal overloads (documented in the package); consider boto3-stubs-lite as an alternative if that occurs.

Install

mypy-boto3-support on PyPI

pip install mypy-boto3-support

uv add mypy-boto3-support

poetry add mypy-boto3-support

Installing mypy-boto3-support

Before you install

Low install friction with a single lightweight runtime dependency (typing-extensions). Actively maintained as of 2026-06-22 with 670 repository stars, supporting Python 3.9 through 3.14.

License in practice

MIT license permits unrestricted use, modification, and distribution in both open-source and proprietary projects with minimal obligations.

Quickstart

pip install mypy-boto3-support

from boto3.session import Session
from mypy_boto3_support import SupportClient

client: SupportClient = Session().client("support")

Requires boto3 1.43.28 to be installed separately; type checking requires mypy, pyright, or a compatible IDE with type-aware language server.

Verify before relying

• Performance impact on PyCharm with Literal overloads (documentation references issue PY-40997 but resolution status is unclear)
• Whether the package works correctly with boto3-stubs-lite as a drop-in replacement when performance is a concern
