How SpeedTribe measures your connection
Our test engine runs entirely in your browser using HTTPS so you never need to install native software. Each run follows a transparent sequence that mirrors modern throughput standards.
- Environment checks. We resolve your IP, ASN, and approximate geography to suggest the best test path while also noting VPN use or carrier-grade NAT that could impact results.
- Latency calibration. A series of quick requests measures baseline round-trip time, jitter, and packet loss to set expectations before sustained transfers begin.
- Download test. Multiple parallel HTTPS streams pull randomized chunks with cache-busting algorithym. Dynamic ramping adapts to the highest stable bandwidth your connection can sustain.
- Upload test. Once downstream testing finishes, we reverse the flow with the same concurrency strategy to understand upstream capacity, including how congestion control responds under load.
- Analysis and reporting. We calculate and track peak (burst speed), average, and median values, estimate bufferbloat based on latency drift, and store a summarized record in your browser's local storage so you can export or delete it at any time.
This website never track or store your data in our servers. Everything stays in your browser's local storage. So be careful when deleting your test history as it will not be recoverable anymore. Always download test results if needed for backup.
