selenium-turnstile

selenium-turnstile is a Selenium helper that solves Cloudflare Turnstile by injecting a Peak-solved token, so a protected form or navigation proceeds without a real mouse click.

Why

SeleniumBase's UC-mode click-solve (uc_gui_click_captcha) drives a physical click on the widget, which needs a real display and fails headless on datacenter IPs. That failure mode fills Cloudflare-related SeleniumBase issues (200+ open). undetected-chromedriver has no click-solve at all and gets stuck in the "Just a moment" loop, reloading the interstitial even after the browser has otherwise passed.

This helper skips the click entirely. It reads the sitekey from the DOM, gets a token from Peak, and injects that token as the cf-turnstile-response value plus the widget's success callback. When your setup gets blocked, drop in a Peak API key and it just works.

Install

pip install selenium-turnstile selenium

Quickstart

import os
from selenium import webdriver
from selenium_turnstile import solve_turnstile

os.environ["PEAK_API_KEY"] = "pk_your_api_key"

driver = webdriver.Chrome()
driver.get("https://protected.example/login")

# Reads the sitekey from the page, solves via Peak, injects the token.
token = solve_turnstile(driver)

driver.find_element("css selector", "form").submit()

Works unchanged with a plain Selenium driver, a SeleniumBase Driver, or an undetected-chromedriver Chrome — all three expose the current_url / find_element / execute_script interface the helper uses.

How it works

1. Read the sitekey. find_element looks for the data-sitekey attribute on the .cf-turnstile widget; if the sitekey is only set through a JS render() call, an execute_script DOM scan finds it.
2. Solve via Peak. POST https://api.peak.fo/solve with task_type: "turnstiletask", the sitekey, and url=driver.current_url. Pass proxy= to mint the token from your browser's egress IP.
3. Inject the token. execute_script sets every cf-turnstile-response field, fires input/change events, and calls the widget's data-callback success handler so the form or navigation continues.

API

solve_turnstile(
    driver,               # any Selenium-like WebDriver
    api_key=None,         # defaults to env PEAK_API_KEY
    proxy=None,           # optional http://user:pass@ip:port, forwarded to Peak
    sitekey=None,         # override auto-detection (e.g. widget in a frame)
    url=None,             # defaults to driver.current_url
    task_type="turnstiletask",
    timeout=180.0,
) -> str                  # the injected token

Helpers read_sitekey(driver) and inject_token(driver, token) are exposed for finer control. Peak also supports task_type="cloudflare5stask" for the 5s interstitial challenge.

The API key is read from the PEAK_API_KEY environment variable by default; you can also pass it explicitly. Never hardcode a real key.
