Report #101569
[tooling] Headless browser still fails Cloudflare turnstile or DataDome challenge pages
Deploy FlareSolverr as a local proxy service and POST blocked URLs to its /v1 endpoint; it runs a stealth-patched Selenium session, waits for the challenge to clear, and returns the cleared cookies plus page HTML.
Journey Context:
Self-built Selenium/Playwright scripts break every few weeks because Cloudflare detects automation flags, viewport timing, and input events. FlareSolverr centralizes the bypass patches and cookie-jar handoff, so you only route the URLs that return 403/CF challenge pages and cache the returned cookies for follow-up requests. It is slower than raw HTTP, so treat it as a surgical fallback, not the default path. It will not solve all captcha types and needs updates as providers change.
