Proxy Speed Test
Measure your proxy's real-world performance — latency, download speed, and upload speed. Connect through your proxy and hit start.

Latency Test
Measures round-trip time (ping) between your connection and our servers with multiple samples.
Download Speed
Downloads test data to measure your real throughput from our Vercel edge network.
Upload Speed
Uploads test data to measure how fast your connection can send data upstream.
Frequently Asked Questions
How does this speed test work?
Your browser sends and receives data packets to our Vercel edge servers. We measure the round-trip time (ping), download throughput, and upload throughput in real-time — all from your current connection.
Can I test my proxy speed with this?
Yes — that's exactly what it's built for. Connect through your proxy first, then run the test. The results show the actual speed between your proxy and our servers.
Is the speed test free?
Completely free, no account needed. Run as many tests as you like.
What is ping / latency?
Ping measures the round-trip time for a tiny data packet to travel from your connection to our server and back. Lower is better — under 100ms is good, under 50ms is excellent.
What is jitter?
Jitter measures the variation in ping times. Low jitter means a stable connection. High jitter can cause lag in real-time applications like video calls or gaming.
Why are my speeds lower than expected?
Proxy connections add an extra hop between you and the destination, which naturally adds latency. Mobile proxies typically range from 5–50 Mbps download speed depending on carrier and signal strength.
