requests-futures

What it is and what it does

requests-futures is a lightweight wrapper around the requests library that enables asynchronous HTTP requests using Python's concurrent.futures module. Instead of blocking on each request, you create a FuturesSession that returns Future objects immediately, allowing you to issue multiple requests in parallel and retrieve responses when ready. The API mirrors requests.Session closely, minimizing the learning curve—you swap FuturesSession for Session and call .result() on the returned Future to get the Response.

The package uses a ThreadPoolExecutor by default with 8 workers, which you can customize or replace entirely. It preserves the requests API's behavior including hooks, session configuration, and exception handling, with the main difference being that exceptions are deferred to the .result() call rather than raised immediately. This makes it useful for scenarios where you need to make many HTTP calls concurrently without switching to a fully async framework.

Use it for:

• Fetch data from multiple APIs in parallel without blocking, then process all responses together
• Implement concurrent web scraping that issues many requests simultaneously and collects results
• Background HTTP operations in foreground-focused applications where you want requests to proceed while other work continues
• Batch processing workflows that need to make many HTTP calls with controlled concurrency via thread pool size
• Canceling pending requests in a context manager to avoid wasted resources on unneeded work

Worth the install?

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

Wraps the requests library to execute HTTP requests asynchronously using thread pools, returning futures instead of responses so multiple requests can be issued and resolved in parallel.

Yes, if you need concurrent HTTP requests and prefer a minimal, requests-compatible API over learning a full async framework. The low install friction, active maintenance, permissive license, and zero known vulnerabilities make it a safe choice. Not recommended if you require true async/await syntax or need to handle thousands of concurrent connections—consider a modern async HTTP library instead.

Install

requests-futures on PyPI

pip install requests-futures

uv add requests-futures

poetry add requests-futures

Installing requests-futures

Before you install

Low friction install with a single runtime dependency on requests. Actively maintained with recent commits and stable production status since 2013.

License in practice

Apache License v2 is permissive; you can use this package in commercial and proprietary projects with minimal restrictions.

Quickstart

from requests_futures.sessions import FuturesSession

session = FuturesSession(max_workers=10)
future = session.get('http://example.com')
response = future.result()
print(response.status_code)

Verify before relying

• Whether the package supports async/await syntax or only futures-based concurrency
• Performance characteristics compared to modern async HTTP libraries
• Whether thread pool size and executor configuration are sufficient for high-concurrency workloads
