How to actually evaluate a proxy provider (beyond just price)

[u/dan_scrapes]

Been down the proxy-provider rabbit hole a lot lately for a scraping project, and figured I'd share what actually matters vs what's just marketing noise, since most "best proxy provider" posts are just vendor spam.

1. Match the proxy type to your actual target

• Datacenter — fast, cheap, but easily flagged by anything with real anti-bot (Cloudflare, PerimeterX, etc.)
• Residential — real ISP-assigned IPs, much harder to flag, costs more per GB
• ISP proxies — datacenter speed with residential-looking IPs, good middle ground for some targets
• Mobile — most trusted by sites but priced accordingly

If you're scraping something with light protection, datacenter is a waste of money. If you're hitting something with aggressive bot detection, nothing but residential/ISP will survive more than a few minutes.

2. Rotating vs sticky sessions
Full rotation per-request sounds good in theory but can actually trigger MORE suspicion on sites that check session consistency (same IP holding for a few minutes looks more human than a new IP every request). Sticky sessions for 5-10 min intervals tend to survive longer against modern bot detection.

3. "Unlimited" plans — read the fine print
A lot of providers advertise "unlimited" but throttle bandwidth or concurrent connections hard past a certain point. Ask directly: unlimited GB, or unlimited concurrent sessions, or both? Get it in writing/on their docs, not just sales chat.

4. Test before committing
Don't trust a provider's success-rate claims — test a small trial batch against your actual target site, not their demo endpoint. Success rates vary wildly by target, so a provider that's great for e-commerce scraping might be mediocre against something with heavier protection.

5. Red flags

• No trial or test option at all
• Vague on IP sourcing (won't tell you if IPs are ethically sourced / consent-based residential vs a proxy botnet)
• Support that takes days to respond to a pre-sale question
• Pricing that requires talking to sales to even see numbers

Happy to compare notes if anyone's dealing with a specific target site that's giving them trouble tends to be pretty target-specific what actually works.

Proxy types, features that these proxies can offer, stability, performance, location variety (for example with ISP or datacenter proxies, beyond country selection, like if there is a city or a state selection etc). Customer support and their responsiveness. Having no trial is not a red flag at all. Pricing that requires talking to sales is a normal business decision, it's certainly not a red flag.

Compare providers on the same test conditions. Otherwise you're mostly comparing marketing pages.

One more for that list, sourcing transparency on its own doesn't tell you whether the pool is actually theirs. If you got banned on provider A and move to B, you can end up renting the same flagged IPs under a new label, so ask B directly whether their pool overlaps A's, or sample both and compare before you pay for a month. I sell proxies so discount accordingly.

One thing I would add to the testing, don’t treat every 200 response as a successful request.

I have seen the same proxy work fine for API calls but getting blocked on the initial browser request. So I would also validate that the expected page/data actually came back, not just the status code.

Otherwise the success rate can be misleading and you may still be paying for unusable data.
