How to Find the Best Proxy Provider — 2026 Guide
Pool quality, ASN diversity, rotation models and pricing — what really matters when picking residential proxies for anti-detect work.
Your anti-detect browser is only half the stack. The proxy is the other half — and most failures we diagnose are proxy failures, not browser failures.
What separates good from bad
ASN diversity
A "residential" pool concentrated in 3 ASNs is detectable. Real residential traffic comes from dozens of ASNs per city. Ask your provider for an ASN distribution report; if they refuse, walk away.
Pool freshness
How long are IPs in the pool? Healthy pools recycle IPs every 30–90 days. Stale pools (some on the market are >2 years stale) are flagged by anti-bot systems en masse.
Sticky session length
10–30 minutes is the sweet spot. Shorter, and you can't complete checkouts. Longer, and your "user" looks unusually attached to a single IP.
IP geolocation accuracy
A proxy claiming "Berlin" should be in a Berlin ASN, in MaxMind as DE, and in IP2Location as Berlin. Mismatch = instant flag.
How to test before committing
- Request a trial (1–5 GB)
- Pull 100 IPs from your target country
- Check each IP against:
- ipinfo.io — type should be "isp" / "broadband"
- MaxMind — country/city match
- Spamhaus — should not appear in DROP/EDROP lists
- Test 10 random IPs against iphey.com with Afina — should be all-green
- Test against demo.fingerprint.com — should score "low" bot probability
If 90/100 IPs pass, the pool is good. Below 80%, walk away.
Pricing models
| Model | Best for | Notes |
|---|---|---|
| Per GB | Bursty traffic, varied site weights | Most flexible |
| Per port | Long-running automations | Cheaper for >100GB/month |
| Unlimited | Specific use case promises | Usually capped at fair use |
For anti-detect work, per-GB is the default. $4–$6 per GB for tier-1 residential, $10–$15 for mobile.
Red flags
- "Unlimited" plans without throttling clauses — never sustainable
- Free credits without KYC — pools are publicly known and burnt
- Multiple "premium" tiers within the same pool — usually marketing
- No trial — providers confident in quality offer trials
- API rate limits below 100 req/s — operationally painful
Top tier-1 providers (alphabetical)
We don't link to providers we don't operate with. The names we currently see clean output from: Bright Data, IPRoyal, Oxylabs, Soax, Smartproxy. Mobile: Airproxy, Proxidize.
The market shifts; re-evaluate quarterly.
Specific recommendations by use case
- Affiliate marketing (Facebook/TikTok Ads) — residential, tier-1, paired with Afina UDP
- E-commerce multi-accounting — residential mid-tier; less sensitive
- Crypto KYC — residential tier-1 + clean history; this is where pool quality matters most
- Web scraping — datacenter is fine; switch to residential only when blocked
Final note
A great anti-detect browser cannot fix a bad proxy. A great proxy cannot fix a bad anti-detect browser. Pair Afina with a tier-1 residential provider and you have a baseline you can trust.
