Steel

Steel charges per successful request, starting at $0.10 per request for the basic plan with volume discounts for higher usage. Failed requests aren't charged, and there's no monthly minimum. For high-volume operations (10,000+ requests/month), custom pricing is available. The cost includes proxy usage, JavaScript rendering, and infrastructure, making it predictable compared to managing your own proxy pools and browser instances.

Yes, Steel's session management can handle OAuth flows, multi-factor authentication, and complex login sequences. You can send multiple requests to perform login steps, then use the authenticated session for data extraction. The service maintains session state including cookies, local storage, and authentication tokens. However, sites with email verification or SMS-based 2FA require manual intervention and aren't suitable for automated workflows.

Steel provides monitoring and alerting for failed extractions, but you'll need to update your CSS selectors when sites change their HTML structure. The platform offers a testing environment where you can validate selectors against live pages before running production jobs. For mission-critical scraping, consider implementing multiple fallback selectors and monitoring extraction success rates to catch changes quickly.

Steel eliminates the need to manage proxy infrastructure, handle browser automation, and deal with anti-bot detection - typically months of engineering work. The main trade-offs are cost and customization: Steel is more expensive per request than self-built solutions but includes infrastructure, maintenance, and anti-detection capabilities. For complex scraping logic or very high volumes, in-house solutions may be more cost-effective, but Steel reduces time-to-market significantly.
