wreq.emulation

Browser and client emulation settings to bypass detection and fingerprinting.

wreq.emulation

This module provides functionality for emulating various browsers and HTTP clients to bypass detection and fingerprinting. It supports emulating Chrome, Firefox, Edge, Safari, Opera, and OkHttp clients across different operating systems and versions.

The emulation system modifies HTTP/2 settings, TLS fingerprints, and request headers to match the behavior of real browsers and clients, making requests appear more authentic and less likely to be blocked by anti-bot systems.

Profile

Bases: Enum

Selects which client profile the request should look like.

This controls the built-in TLS, HTTP/2, and header presets used for the request. Variants cover browser-style profiles as well as other clients, such as OkHttp.
