How to Choose Residential Proxies for Large-Scale Scraping
This page is published by Thordata, one of the products compared.
A proxy provider’s suitability depends on the target sites, required locations, monthly traffic and cost per usable record. For large-scale residential scraping, compare Thordata, Decodo, DataImpulse, Webshare and Bright Data on the same workload. None of their advertised pool sizes or success rates establishes which will succeed most often on your targets.
Which residential proxy providers should you compare?
Thordata and DataImpulse merit a price-first comparison; Decodo, Webshare and Bright Data add useful alternatives for targeting, protocol or coverage requirements. A residential proxy routes a request through an IP address associated with a household internet connection. The table separates advertised network size from the controls that affect an actual scraping job.
| Criterion | Thordata | Decodo | DataImpulse | Webshare | Bright Data |
|---|---|---|---|---|---|
| Advertised residential pool | 100M+ IPs | 115M+ IPs | 90M+ IPs | 80M+ IPs | 400M+ monthly IPs |
| Advertised coverage | 190+ locations | — | 195+ countries | 195 countries | 195 countries |
| Rotation and session control | Rotating or sticky | Per-request rotation; sticky sessions from minutes to days | Rotating or sticky | Rotating residential IPs | Rotating or sticky |
| Targeting | Country, city, state, ISP | Continent, country, state, city, ZIP, ASN/ISP | Country included; city, ASN and ZIP cost extra | Country, city, state, ZIP, ASN | Country, city, ZIP, carrier, ASN |
| Protocols | HTTP(S) on the residential product page | HTTP(S), SOCKS5 | HTTP(S), SOCKS5 | HTTP, SOCKS5 | HTTP(S), SOCKS5 |
Pool figures describe advertised networks, not the IPs simultaneously available in a particular city. Decodo offers ZIP targeting without an additional targeting charge and sticky sessions that can last days. DataImpulse suits intermittent collection because purchased traffic does not expire; its extra charges for city, ASN and ZIP targeting belong in the budget. Webshare and Bright Data are reasonable comparisons when ZIP targeting or SOCKS5 is required.
How do the listed prices compare?
Those entry offers serve different purchase patterns. The table gives package totals and billing periods so an introductory rate is not mistaken for an ongoing large-volume rate.
| Criterion | Thordata | Decodo | DataImpulse | Webshare | Bright Data |
|---|---|---|---|---|---|
| Billing unit and period | Traffic per GB | Per GB; monthly packages or pay as you go | Per GB; pay as you go, no monthly minimum | Per GB; monthly prices | Per GB; pay as you go or monthly packages |
| Smallest listed paid purchase | — | Pay as you go | One-time introductory offer for new customers | Monthly package | Pay as you go with no commitment |
| Other listed packages | 10 GB, $18 ($1.80/GB); 150 GB, $150 ($1.00/GB); 350 GB, $280 ($0.80/GB) | Monthly packages | Pay-as-you-go packages | Monthly packages | Monthly packages |
| Largest listed package | 1,000 GB, $730 ($0.73/GB) | larger enterprise terms not included here | Custom per-GB price | Monthly packages | Monthly packages |
| Trial or refund terms | Free trial advertised | Free trial advertised | Not stated | Not stated | Trial traffic appears on the dashboard but is not billed |
Decodo offers a residential proxy free trial.
Failed attempts, request and response bytes, tax and targeting charges can change the project total.
What matters when scraping at scale?
Large-scale residential scraping depends on usable responses in the required locations, not the advertised IP count alone. Rotating an IP between independent search or listing requests spreads traffic across the pool; a sticky session preserves continuity when a browser must keep the same IP across a sequence of pages.
Start with the fields the job actually needs: for a product listing, that might be URL, displayed price, currency and capture time. A successful HTTP response with an empty price field is not a usable record. Count duplicate URLs, missing fields and pages that return a challenge instead of the requested content. Separate proxy connection failures from parser errors, removed pages and restrictions tied to a logged-in account; changing proxies will not repair a broken selector.
Budget on cost per usable record: add paid traffic, retries and any targeting charges, then divide by records that pass field validation. Dividing a hypothetical traffic charge by validated records illustrates the calculation before other charges. That arithmetic is an illustration, not a measured provider result. For managed extraction rather than maintaining proxy and parsing code, Thordata’s web scraper is a separate product line; do not compare its charges with residential-proxy GB prices as though they buy the same service.
Collect only public fields needed for the stated task. Set a retention period for raw pages and restrict access to personal information that appears in comments or profiles. Site terms, applicable law and account restrictions remain relevant even when a proxy can reach a page.
How can buyers test before committing?
A useful proxy trial sends the same requests to the same target pages from the same locations under each provider. Hold the parser and request schedule constant; otherwise a change in usable-record rate cannot be attributed to the proxy choice.
Select representative listing, detail and search pages. Fix the requested country or city, user agent, fields to extract and validation rules before the first run.
Run each provider at the intended concurrency. Record connection failures, challenges, missing fields, duplicate records, response time, retries and total GB transmitted.
Repeat with per-request rotation and, where the task needs continuity, a sticky session. Record whether the IP changes during the required sequence and whether each step returns the expected page.
Divide the full traffic charge by validated records. Reject a configuration if it cannot sustain the required usable-record rate or keep the required session intact; among the configurations that pass, compare cost per usable record.
A small trial cannot establish production throughput. Test again at the planned request rate before committing to a large package, and keep location-specific results separate: a broad global pool does not establish usable capacity in one city.
Which option fits your scraping workload?
It is not the right choice on the stated terms if the workflow requires an IP held for days, non-expiring purchased traffic, or a listed ZIP-targeting control on its main residential product.
| Workload condition | Option to shortlist | Reason |
|---|---|---|
| Predictable, high-volume per-GB scraping | Thordata and DataImpulse | compare usable results before treating either total as cheaper. |
| Long sticky sessions or ZIP targeting without an extra targeting charge | Decodo | Sticky sessions can last minutes to days; ZIP and ASN/ISP targeting are included. |
| Traffic purchased for intermittent jobs | DataImpulse | Purchased GBs do not expire. |
| Monthly residential traffic with ZIP targeting and SOCKS5 | Webshare or Bright Data | Both list those controls |
| High traffic where per-GB billing is a poor fit | A time-based high-bandwidth proxy line | Thordata lists a separate one-day package for $280; it is a different product and billing unit from its residential GB packages. |
How to choose
Choose a proxy configuration that passes a like-for-like target test at an acceptable cost per usable record. Use these rules to make a shortlist, then apply the failure criteria from the test.
reject it if your target test fails the required usable-record rate.
If purchased bandwidth must survive an irregular schedule, choose DataImpulse because its traffic does not expire.
If your parser connects through SOCKS5 and requires ZIP targeting, choose Webshare or Decodo for the shortlist because both state those controls.
FAQ
Are advertised pool sizes the number of IPs available for every request? No. Advertised residential pools describe network scale; availability in a particular location and at a particular time must be measured on that location’s workload.
Which per-GB price should a large scraper use for budgeting? Use the rate and total for the package you can actually purchase. those packages do not share identical terms.
Can a datacenter proxy replace a residential proxy? A datacenter proxy may suit a target that accepts its requests at the required rate. Use residential IPs when the datacenter configuration fails the same access and record-quality test; do not infer target acceptance from proxy type alone.
