About

Portproof sells proxy traffic by the GB through mobile 4G/5G carrier-modem and mixed peer-network pools. One balance covers both. Mobile exits span the US, UK, France, Netherlands, Poland and Georgia (country); the peer pool combines home broadband and mobile connections. Set pool, country, rotation and sticky session in the proxy username; connect over HTTP or SOCKS5. Rotation options include per connection, every 5, 10, 20 or 60 minutes, or sticky sessions. Per-GB pricing falls with order size, from EUR 1.99 to EUR 0.89, and purchased GB never expire. A one-time paid trial costs EUR 1.49 per customer. Unused whole GB are refundable within 14 days. Payment is by cryptocurrency. The dashboard builds connection strings, provides curl, Python, Node and Playwright examples, and tests the gateway. An API and MCP server support automated workflows. Use cases include price monitoring, ad verification, market research, QA and geo-testing, subject to the acceptable-use policy.

About

Shifter is a residential proxy network for collecting public web data at a lower cost than major providers. It has operated since 2012. In our published benchmarks we tested Shifter against the biggest names in residential proxies, using the same method for everyone. Shifter costs less than half of what most of them charge per GB, gives you a comparable or bigger IP pool, and has lower latencies, often by 50% or more. The network covers 205M+ residential IPs in 195+ countries through one gateway endpoint over HTTP, HTTPS or SOCKS5. Country, state, city and ASN targeting is set in the proxy username. Sessions rotate on every request or stay on one IP for a set time, concurrency is uncapped, and usage is billed per GB. A dashboard shows live bandwidth and requests, team workspaces, a usage API and guides for Python, Node.js, Go, PHP, Selenium, Playwright and Puppeteer.
