Bandwidth refers to the total amount of data transferred through your proxy connection, measured in gigabytes. Every page load, API response, image download, and data transfer consumes bandwidth. In the proxy industry, bandwidth is the most common billing metric, with most providers charging between $5 and $15 per gigabyte of residential proxy traffic.
Most residential proxy providers sell bandwidth by the gigabyte. You buy a block of data (say 10 GB), and every byte that flows through the proxy counts against your balance. Once you hit your limit, traffic stops or you get charged overage fees. This model creates unpredictable costs, especially for data-heavy tasks like scraping image-rich sites or downloading large datasets.
The alternative is unmetered bandwidth, where you pay a flat monthly fee and transfer as much data as you want. Your throughput is governed by concurrent connections (threads), not by a data cap.
Per-GB pricing forces you to optimize for minimal data transfer instead of optimal results. You end up stripping images, limiting requests, and second-guessing every scraping job. That is the wrong tradeoff. ScaleProxy uses an unmetered model where all plans include unlimited bandwidth. You pay for threads, not data. Run your workload without counting bytes.
To put it in perspective: 100 threads on the Starter plan at $79/month could easily transfer hundreds of gigabytes in a single day. At per-GB rates, that would cost thousands. With ScaleProxy, it costs $79. Flat.
ScaleProxy is unmetered. Flat rate. No overages. Start your $10 for 10 days trial.
