Concurrent connections represent the number of simultaneous active connections your scraper or application opens to the proxy gateway at any given moment. Each connection is an independent link that can route through a different residential IP address. A scraper running 500 parallel requests has 500 concurrent connections open.
When your scraper, browser, or application opens a connection through the proxy gateway, it routes through a residential exit IP. Once that request completes, the connection is freed. The number of concurrent connections you open is determined by your scraper's concurrency settings, not by your proxy plan. Some providers cap concurrent connections, but most don't meaningfully need to.
ScaleProxy does not cap concurrent connections. Open as many parallel sessions as your scraper needs. Instead of limiting concurrency, we publish a guaranteed Mbps floor per plan. Your aggregate bandwidth is capped at the Mbps you purchase. Individual connections don't fight for slot availability, they share the aggregate throughput budget.
This is a better model than per-connection billing. You don't tune scraper concurrency to avoid hitting a cap. You tune it for what's efficient for your target site. And bandwidth is unmetered, so you never worry about per-GB overages.
Pick your Mbps tier, open as many parallel connections as your scraper needs. Start with a $10 for 10 days trial.
