With Scrapfly, you choose your proxy pool, JS rendering, and set the ASP on a per-request basis. Get it wrong, and you'll waste credits and have to reconfigure manually. ZenRows' Adaptive Stealth selects the right bypass configuration for every target: no manual guesses required.
Scrapfly's residential proxies cost 25x base credits. Add JS rendering, and you're at +30x. Every request commits to the full cost upfront, whether you use the right configuration or not. ZenRows has one flat subscription. No multipliers. No per-feature credit stacks. You pay for results, not for features.
ScrapFly's service interruptions take hours to days to weeks, API credit costs can fluctuate without warning, and the average resolution time is 3–7 business days. Sites' anti-bot changes are handled on ZenRows' end. No parameter updates required. Your code stays the same.

Scrapfly's $30 plan gets 40,000 basic requests. Stack the browser and residential proxies you need for protected sites, and you're down to 1,290 real requests. To match ZenRows' $69 for 10,000 protected requests, you'd need Scrapfly's $100 plan. Same capability, 45% more expensive. Here's the breakdown:

Effective Cost Per Protected Request:
ZenRows is actually 3.3x cheaper for the sites you care to scrape.
Scrapfly’s $30 for 40,000 requests is a credit mirage. For protected targets, you're looking at 1,290 requests. That’s not a pricing tier, it’s a pricing trap.
Migrating from Scrapfly to ZenRows is all about parameter changes. Not a codebase overhaul. Most teams switch in minutes.
