Cheap proxies for public data collection
Government portals, open-data sites and archives often limit each address to a few requests a minute. More addresses at a low price lets a polite crawl finish in reasonable time.
Worked budget: 20 shared datacenter IPs for a month. On the cheap datacenter proxies line that comes to $20.80 at list price. This is an illustration from your own assumptions, not a measurement of any workload.
Why datacenter fits
Public-interest sites rarely run bot-detection against hosting ranges, and the data volume is modest. The cheapest line is usually the right one: a shared datacenter proxy per worker.
Be a good guest
Spread requests so that no address exceeds the rate the site documents, identify your crawler honestly where the site asks for it, and honour robots.txt. More addresses are for staying within a per-address limit, not for exceeding the site’s overall capacity.
Frequently asked questions
How many addresses do I need?
Divide your target request rate by the per-address limit the site allows, then add a few spare addresses for any that get blocked.
Try it for $5
Minimum top-up is $5. Run your own target through it before you scale.
