Latency Test

See real client-side latency, not just server-side benchmarks.

Choosing deployment regions needed latency data, but most tools measured from the server, not from an actual user's browser.

A public deployment is available to try.

Case Study

Before

Choosing deployment regions for globally-distributed portfolio apps required latency data, but existing tools focused on server-side testing and didn't show client-side experience.

After

Provided real client-side latency data that informed deployment region selection. The visual map revealed latency patterns that server-side tools missed, optimizing CDN and edge function placement.

How it's solved

Built a latency testing tool that measures round-trip times from the user's browser to multiple endpoints across regions. Displays results on a world map with color-coded latency zones and historical averages.

Trade-offs

Measurements reflect the testing device's own network conditions, not a controlled, repeatable benchmark environment.
