Need faster, steadier proxy routes?
Rainproxy gives high-throughput residential, mobile, IPv6 and datacenter routes for scraping, automation and live operations that cannot stall mid-run.
How it works
Measure the route your browser is actually taking
A proxy, VPN, mobile network or datacenter route can all change throughput. This test measures from your current browser session, not from our server.
Step 1
Choose a profile
Quick, balanced and extended profiles control the transfer size and number of samples.
Step 2
Run live probes
Your browser measures ping, downloads test payloads and uploads generated data to Cloudflare speed endpoints.
Step 3
Read stable results
We use median samples so one cold request or temporary spike does not dominate the final number.
Tests your real route
Measures the network path visible from this browser, including VPNs, proxies and mobile tethering.
Three test sizes
Use quick checks for a fast pulse or extended checks when you want steadier throughput numbers.
No stored history
Results stay in the page. The generated upload payload is random test data, not your files.
