Fast data collection is not just about choosing a Python library. It depends on how closely your client behavior matches the target environment. Requests, curl_cffi, and Playwright solve different problems. Requests is lightweight and simple, curl_cffi improves TLS and browser impersonation behavior, while Playwright runs a real browser environment. The right choice depends on performance, stability, reliability, and whether the target requires JavaScript execution or realistic protocol behavior. What is the difference between Requests, curl_cffi, and Playwright? Requests is a lightweight HTTP client for sending direct web requests. curl_cffi is a Python binding for curl-impersonate that can mimic browser TLS and JA3 fingerprints. Playwright is a browser automation framework that runs real browser engines such as Chromium, Firefox, and WebKit.…
