On published prices, the cheapest residential proxies in our database are Evomi at $0.49/GB on a subscription and DataImpulse at $1/GB, with DataImpulse falling to $0.80/GB at 1 TB. Both come with conditions, which is why this ranking sorts by effective price at about 100 GB rather than by the first number on a homepage.
Pool sizes are vendor claims, and they differ: DataImpulse advertises 90M IPs and Evomi 54M, against 400M at Bright Data. A smaller pool is not automatically worse. It matters when you need one narrow city or ASN, because a small slice of a small pool means you will see the same IPs more often.
Thordata advertises a headline from $0.65/GB, but we have not verified its volume tiers or minimum commitments, so treat that figure as a lead to check, not a price to budget on. The table above lists the providers at or below $2.75/GB at 100 GB. For the wider market, including pricier networks with deeper targeting, see the best residential proxies.
