Cloudflare vs Spider Cloud

These tools overlap on nothing material because they solve different jobs. Spider Cloud's entire surface is getting web content out: single-page scrape to markdown/JSON/HTML, whole-site crawl streamed as JSONL as pages land, a search endpoint returning SERP results plus scraped pages plus AI extraction in one call, and a prompting mode that returns named fields as JSON. Rendering is first-class — scripts run, lazy images load, infinite scroll completes — and bot walls, CAPTCHAs, and geo checks are handled in-request, with protected sites routed to browser.spider.cloud sessions that have stealth and CAPTCHA solving on by default. The September 2026 provider router lets scrape and crawl bodies route to outside providers on your own keys, and mcp.spider.cloud plus the spider-agent CLI and SKILL.md let a coding agent self-onboard.

Cloudflare is infrastructure you build on rather than a data source. Workers bills on 1ms CPU with no wall-clock charges; Durable Objects now run up to ten Dynamic Workers concurrently per object; R2 has no egress fees; Zero Trust SASE is free for the first 50 employees. Its AI side — AI Gateway spend limits, Workers AI with GLM-5.3 on a 1M token context window and function calling, and AI Search over your own data — consumes and serves content, but does not render or unblock third-party sites for you. Python Workers reaching GA (2026-09-21) and per-Worker access scoping (2026-09-15) sharpen the developer story. The honest read: Spider supplies data, Cloudflare supplies the runtime and perimeter.

Both are freemium, but the meters measure different things, which is why cost comparisons across them are meaningless. Spider Cloud offers a flat-rate Unlimited tier where concurrency isn't metered per request — attractive for high-throughput crawls — alongside pay-as-you-go for the jobs Unlimited can't do yet, notably geo-targeted crawls. Buyers consistently misjudge the add-ons: residential/ISP proxy pools and AI extraction bill separately rather than bundling into base request pricing, so estimate volume, proxy usage, and extraction calls independently before committing. Unlimited also queues nothing server-side, so a client that can't handle HTTP 429 and back off will burn requests.

Cloudflare's free tier is famously generous — 100k daily requests plus 50 free Zero Trust seats — and its pricing philosophy is to avoid charging for idle time: a 2,500ms LLM call burning 0.5ms of CPU costs 0.5ms. R2's zero egress fees change the storage math against hyperscalers, and enterprise SASE beyond Free or the $7/user tier requires a custom contract. The practical guidance: budget Spider as a metered data-acquisition line item (requests + proxies + extraction), and budget Cloudflare as platform spend (compute, storage, security seats). If you ran Spider's data pipeline on Cloudflare Workers, you'd pay both — they're complements, not substitutes.
