Best proxies for hard-to-crack targets
When a target blocks aggressively, success rate beats price. One caveat first: the public 2026 numbers were measured on an easy CDN endpoint, and every network scores lower on genuinely hard targets. Use them to rank, not as a promise, and budget a test run against your own targets.
1. 
Oxylabs Highest measured successOur pick
Oxylabs topped the 2026 testing at 99.93% on a 175M+ pool, with a 0.60s average response. On the hardest targets its size and quality show. The cost is real: $6/GB to start, dropping to $2.50 only at 1000 GB.
2. 
Decodo (formerly Smartproxy) Almost as good, cheaper and faster
Decodo measured 99.92% and was the fastest network at 0.53s, starting at $4/GB. The gap to Oxylabs is inside the margin of error on the easy test, so for most hard targets it is the better value.
3. 
Bright Data Biggest pool for the worst targets
When a site blocks everything in sight, Bright Data's 400M+ pool and Web Unlocker are what finish the job. The catch is there is no 2026 independent number for it, so you are trusting reputation and your own testing rather than a fresh benchmark.
Read the success numbers carefully
The 2026 figures above were all measured on an easy CDN endpoint. Hard targets score lower for every network, sometimes far lower, so a 99% on the chart does not mean 99% on a site with serious anti-bot defenses. Treat the numbers as a ranking and confirm with a small paid test before you commit volume.
The call
For hard targets, start with Oxylabs for the top measured success, or Decodo for nearly the same at a lower price. Keep Bright Data in reserve for the targets that beat both, where the bigger pool and the unblocker earn their cost.
Whatever you pick, run it against your own targets before you scale.
FAQ
Which proxy has the highest success rate?
Oxylabs, at 99.93% in the 2026 testing, with Decodo a hair behind at 99.92%.
Are those success rates real for my targets?
They were measured on an easy endpoint. Hard targets score lower for every network, so treat the numbers as a ranking, not a guarantee.
Do I need residential or a scraping API for hard targets?
If you would rather not tune rotation yourself, a managed unblocker like Bright Data's Web Unlocker, or a scraping API, can be worth it on the hardest sites.
