The best Python HTTP clients for web scraping

Requests, urllib3, aiohttp, and HTTPX are the best Python HTTP clients for web scraping, each for a different job: lightweight simplicity (Requests), low-level control (urllib3), async scraping (aiohttp), and a modern sync/async combo (HTTPX). Choosing the right one depends on what you’re building. A single-script scraper and a high-concurrency crawler have very different needs around connection pooling, retries, timeouts, and async support.
