Here is the quiet frustration with per GB proxy pricing.

The better your scraper gets, the more it costs you. You optimise, you speed things up, and the invoice goes up with it. Success becomes an expense.

9Proxy sells residential proxies on unlimited bandwidth instead, and if that sentence made you sit up slightly, this review is for you.

The Model Is the Point

Most residential providers meter you by the gigabyte. 9Proxy's pitch is premium residential IPs with unlimited bandwidth, backed by 24/7 support and a refund policy they put front and centre.

What that changes in practice:

  • You stop rationing requests
  • Your monthly cost becomes a fixed line rather than a variable one
  • Heavy pages, images and media stop being scary

Anyone who has watched a single image heavy target eat half a month's allowance understands why this matters.

Where Unlimited Genuinely Wins

Media heavy targets

Product pages with forty images, video listings, anything where the HTML is the small part of the payload. Per GB pricing turns these into a budget problem. Unlimited turns them back into an engineering problem, which is the one you can actually solve.

Long running sessions

If you are keeping a browser open and driving it, bandwidth accumulates quietly in the background. A flat model means you never have to think about it.

Learning and experimenting

When you are still working out what your scraper should do, you waste bandwidth. That is not a failure, it is how the work goes. It should not cost extra.

The Support and Refund Angle

Two things 9Proxy chooses to lead with are round the clock support and a refund policy.

Support matters more in proxies than people expect, because when something breaks you usually cannot tell whether it is your code, your target or the IPs. A provider who will actually answer that question saves you an evening.

A refund policy is a provider putting a small amount of skin in the game. It does not prove quality, but it is a better signal than a testimonial.

Who Should Consider It

  • Scrapers working on bandwidth heavy sites
  • Anyone whose per GB bill keeps surprising them
  • People who want a predictable fixed monthly cost
  • Teams running long automated browser sessions

Who Might Look Elsewhere

If your usage is genuinely small, a few gigabytes a month, per GB pricing will be cheaper and you should take it. Unlimited plans only pay off past a certain volume.

Unlimited models also usually trade against concurrency or pool depth somewhere. Ask about thread limits before you commit, because that is where the real ceiling tends to live.

Final Verdict

9Proxy is worth a look for one clear reason: it prices the thing that actually hurts.

If you have ever throttled your own scraper to protect a bandwidth allowance, you already know the value of taking that decision off the table. Fixed cost, unlimited transfer, support on hand and a refund path if it does not work out.

Do the maths on your current bill first. If you are past the crossover point, this model will feel like a weight coming off. Test the IPs against your targets with a proxy checker before you scale up, and read how to scrape without getting blocked so the bandwidth goes somewhere useful.
