aioaws
Asyncio SDK for some AWS services.
Decision gist · record as of 2026-08-14
Yes, if you need async S3, SES, or SNS access and want to avoid boto3's weight and complexity. The type hints, clean API, and permissive MIT license make it a solid choice for new async projects. No, if you require active maintenance, frequent updates, or comprehensive AWS service coverage—the package is dormant and covers only three services. Yes-with-conditions if you're already committed to asyncio and can live with no upstream support; test thoroughly in your environment first.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires Python 3.10 or later; you must provide AWS credentials (access key, secret key, region) and an httpx.AsyncClient instance.
- Low install friction with five lean runtime dependencies.
- The package is marked Production/Stable and supports Python 3.10+.

Alternatives
Verify before relying
pip install aioaws
from aioaws.s3 import S3Client, S3Config
from httpx import AsyncClient
async with AsyncClient() as client:
s3 = S3Client(client, S3Config('access_key', 'secret_key', 'region', 'bucket.com'))
await s3.upload('path/to/file.txt', b'content')
files = [f async for f in s3.list()]- Whether SNS signature verification works with current AWS SNS certificate formats and rotation practices.
- Performance characteristics under high concurrency or large file uploads compared to other async AWS clients.
- Whether the library handles all AWS S3 error responses and edge cases in production workloads.
What it is and what it does
aioaws is a minimal, type-hinted asyncio SDK for three AWS services: S3 (upload, download, list, delete, signed URLs), SES (email with attachments and multipart), and SNS (webhook verification). It implements AWS Signature Version 4 authentication from scratch and depends only on aiofiles, cryptography, httpx, and pydantic—no boto or boto3. The library is formatted with black and passes mypy in strict mode, making it suitable for codebases that prioritize type safety and debuggability.
The package is stable and production-ready but dormant: the last release was 2024-08-16 and the last commit in 2024-11-18. It works well for developers who want a lightweight, async-first alternative for specific AWS services, but you should expect no active maintenance or new features. The small dependency footprint and clean API make it attractive for serverless functions or microservices where bundle size matters.
Use it for
- Upload and manage files in S3 from async Python applications without boto3 overhead.
- Send transactional emails via SES with attachments in async contexts (e.g., FastAPI handlers).
- Verify and process SES delivery notifications via SNS webhooks in web frameworks.
- Generate signed S3 URLs for direct browser uploads or time-limited downloads.
- Build lightweight AWS integrations in serverless functions where minimal dependencies are critical.

Before you install
Low install friction with five lean runtime dependencies. The package is marked Production/Stable and supports Python 3.10+. Maintenance is dormant—last commit was 2024-11-18 and no release since 2024-08-16—so expect no active bug fixes or feature updates, though the codebase is stable.
Requires Python 3.10 or later; you must provide AWS credentials (access key, secret key, region) and an httpx.AsyncClient instance.
