How to Choose a Proxy Provider in 2026

Selecting a proxy network for web data collection, price verification, or multi-region QA requires evaluating IP pool origin, billing unit mechanics (per-GB vs. per-IP), session persistence, and protocol compatibility. Here is how engineering teams evaluate commercial proxy providers.

Featured Provider: 2Captcha Proxy

Featured at #1 in our manually curated demonstration ranking, 2Captcha Proxy advertises Residential, Datacenter, ISP, and Mobile proxy pages across 220+ countries with Country, Region, City, ZIP, and ASN targeting. Connections support HTTP, HTTPS, and SOCKS5 with per-request rotation or sticky sessions up to 120 minutes, billed on a unified pay-as-you-go schedule from $3.99/GB (1 GB) down to $1.25/GB (10 TB).

1. Match the Proxy Category to Your Target Workload

The most consequential decision when selecting a provider is matching the IP pool category to your target servers' Autonomous System Number (ASN) filtering rules. Read our full Residential vs Datacenter vs ISP vs Mobile Proxies comparison for a deep architectural breakdown, or use the quick summary below:

• Residential Proxies: IP addresses registered to consumer broadband ISPs (such as Comcast, Deutsche Telekom, or BT). Because traffic routes through rotating backconnect gateways across real home networks, residential proxies are the standard choice for geo-localized e-commerce scraping, SERP monitoring, and ad verification. All six providers in our directory—2Captcha Proxy, Bright Data, Oxylabs, Decodo, SOAX, and Webshare—offer rotating residential pools.
• Datacenter Proxies: IPv4/IPv6 addresses hosted on cloud and colocation servers. They offer low network latency and low cost (from ~$0.05/IP on Webshare or $0.60/GB on Decodo), making them well suited for high-throughput public APIs and unprotected catalogs.
• ISP (Static Residential) Proxies: Hosted on datacenter hardware but registered under consumer ISP ASNs. They combine static IP continuity with residential ASN classification, making them popular for long-lived authenticated sessions.
• Mobile (3G/4G/5G) Proxies: Routed through cellular carrier CGNAT gateways where hundreds of real mobile subscribers share each public IPv4 address. Mobile proxies carry the highest per-GB cost ($8.00/GB on Decodo, $9.00/GB on Oxylabs, $24.00/GB on Bright Data) and are reserved for mobile-first platforms and carrier-specific testing.

2. Understand Billing Models: Pay-As-You-Go vs. Subscriptions vs. Per-IP

Commercial proxy providers structure pricing around three distinct models. Before committing to a platform, run your expected monthly traffic through our Proxy Bandwidth & Cost Calculator to compare effective unit costs:

• Pay-As-You-Go Bandwidth (Per-GB): You purchase bandwidth without a recurring monthly subscription floor. 2Captcha Proxy starts at $3.99 for 1 GB and scales down to $3.59/GB (10 GB), $2.99/GB (30 GB), $2.25/GB (100 GB), $1.99/GB (200 GB), $1.80/GB (1 TB), and $1.25/GB (10 TB). Decodo offers $4.00/GB PAYG residential bandwidth, Oxylabs offers $8.00/GB PAYG (up to 50 GB/mo), and Bright Data offers $8.40/GB PAYG.
• Monthly Bandwidth Subscriptions: Providers like SOAX require a monthly plan commitment starting at $90/month (25 GB Starter Plan at $3.60/GB, scaling down to $2.00/GB on 800 GB Business plans). Subscriptions lower unit rates for predictable, continuous workloads but create unused capacity if your scraping volume fluctuates.
• Per-IP Static Leases: Common for Datacenter and Static ISP proxies (Webshare from $2.99/mo for 100 Datacenter IPs or $6.00/mo for 20 Static ISP IPs; Bright Data from $0.60/IP Datacenter or $1.30/IP ISP; Oxylabs from $1.20/IP Dedicated Datacenter).

3. Verify Supported Protocols & Authentication Methods

Modern HTTP clients and headless browsers require flexible protocol and authentication support:

• HTTP, HTTPS, and SOCKS5: All six providers in our directory support HTTP, HTTPS, and SOCKS5 connections. Standard HTTP/HTTPS proxy tunnels (using HTTP CONNECT for TLS) work natively with every scraper, while SOCKS5 operates at the transport layer and supports UDP/TCP traffic without rewriting HTTP headers.
• Username / Password vs. IP Whitelisting: All six providers support both credential-based authentication (username:password@gateway:port) and static IP Whitelisting. Credential strings are essential when embedding routing parameters—such as target country, city, or sticky session ID—directly into each request's username field.

4. Evaluate IP Rotation & Sticky Session Controls

Different scraping workflows require different session lifespans:

• Per-Request Rotation (High-Concurrency Crawling): Each HTTP request routed through the backconnect gateway receives a fresh egress IP address. Ideal for stateless product page or search results pagination.
• Sticky Sessions (Multi-Step Flows): Pins a single egress IP to a custom session identifier for a fixed duration so login flows, shopping carts, and CSRF tokens remain consistent. Sticky window ceilings vary by provider: Oxylabs caps residential sticky sessions (sesstime) at 30 minutes, 2Captcha Proxy supports sticky sessions up to 120 minutes, and Decodo allows sticky durations up to 24 hours.

5. Check Geographic & ASN Targeting Granularity

When collecting localized pricing or regional search results, country-level routing is often insufficient. Verify which targeting parameters your provider supports:

• 220+ Countries with ZIP & ASN Targeting: 2Captcha Proxy documents coverage across 220+ countries with Country, Region, City, ZIP, and Autonomous System Number (ASN) targeting.
• Coordinate & Carrier Precision: Bright Data (195 countries) supports Country, City, ZIP, Carrier, and ASN filtering; Oxylabs (195 countries) adds latitude/longitude coordinate targeting; and SOAX (195+ countries) specializes in ISP and mobile carrier filtering.
