Internet Speed Test — Measure Your Connection
Free internet speed test that measures download speed, upload speed, ping, jitter, stability and latency under load (bufferbloat). Includes a connection quality score and real-world usage assessment for streaming, gaming, and video calls.
How to Test Your Internet Speed
Press the button and the test runs automatically. It takes about 30 seconds.
See download/upload speed, ping, jitter, stability, and bufferbloat grade.
The assessment section shows whether your connection can handle streaming, gaming, and video calls.
Results are saved automatically. Open the history section to view trends and export data.
Measure download, upload, ping, and connection quality in seconds

Frequently Asked Questions
How accurate is this speed test?
The test runs several parallel streams against static files on the test server — with no web-application layer in between to distort results. TCP ramp-up is excluded from the math, speed is computed over the steady-state window, and ping is a pure network round-trip.
What is bufferbloat and why does it matter?
Bufferbloat occurs when your latency spikes under load. Even with fast download speeds, high bufferbloat causes lag in games and choppy video calls. We grade it A through F.
What is the Connection Quality Score?
A composite 0–100 score weighs download (30%), upload (20%), latency (20%), jitter (10%) and the latency increase under load (20%).
Why is my speed different from other tests?
Speed test results depend on the server location, test methodology, and network path. Our test measures the real-world path to our server, which may differ from CDN-hosted tests like Fast.com.
