# types-boto3-sns — Type annotations for boto3 SNS 1.43.23 service generated with mypy-boto3-builder 8.12.0

License: permissive · Maintenance: active · Downloads: 217.7K/mo

## What it is and what it does

types-boto3-sns is a type stub package that adds static type information to boto3's SNS service client. It was generated with mypy-boto3-builder 8.12.0 and provides complete type annotations for SNS operations, paginators, and service resources. When installed, it enables IDEs like VSCode, PyCharm, Emacs, and Sublime Text to offer autocomplete and type checking for boto3 SNS code without requiring explicit type hints in your application.

The package is designed as a development-time dependency—you can use TYPE_CHECKING guards to avoid including it in production builds. It works with mypy, pyright, and other type checkers, and is compatible with modern Python versions (3.9–3.14). The package is actively maintained and generated from boto3 1.43.23.

Use it for:

- Enable IDE autocomplete and inline documentation for boto3 SNS client methods in VSCode with Pylance
- Run mypy type checking on SNS-using code to catch type errors before runtime
- Use pyright for static analysis of boto3 SNS operations in CI/CD pipelines
- Get type hints for SNS paginators and service resources in code editors
- Catch incorrect SNS API parameter types during development instead of at runtime

## Worth the install?

AI-flagged interpretation of the facts above — verify before relying.

Provides type annotations and IDE autocomplete support for boto3 SNS 1.43.23, enabling static type checking with mypy, pyright, and other tools.

Yes. If you use boto3 SNS and want IDE autocomplete or static type checking, this is the standard way to get it. Install friction is minimal, maintenance is active, and it carries no license restrictions. The only caveat is PyCharm users may want to test performance or consider the lite variant if they experience slowdowns.

## Install

pip install types-boto3-sns
uv add types-boto3-sns
poetry add types-boto3-sns

## Installing types-boto3-sns

Before you install: Low friction: single runtime dependency (typing-extensions), wheel-only distribution, active maintenance with last commit 2026-06-22. Supports Python 3.9 through 3.14.

License in practice: MIT license (permissive) means you can use this freely in commercial and open-source projects without restriction.

Quickstart:

pip install types-boto3-sns

from boto3.session import Session
from types_boto3_sns import SNSClient

client: SNSClient = Session().client("sns")
# Now mypy and your IDE provide type checking and completion

Verify before relying:

- Whether PyCharm performance issues (PY-40997) mentioned in docs still affect current versions
- Whether the lite variant (types-boto3-lite) is recommended for your specific IDE setup
