Are these network tools free?

Yes. Every diagnostic tool and calculator on SwiftNetScan runs free in your browser, with no registration required.

Do the tools install anything?

No. They run entirely as web pages using standard browser APIs. Nothing is downloaded to your device.

Which tool should I start with?

Start with the internet speed test for a baseline, then use the ping test and packet loss test if the connection feels unstable.

Can I use these tools on mobile?

Yes. Every tool is responsive and works on phones and tablets, including the mobile speed test.

How accurate are browser-based tests?

Browser tests measure real HTTP throughput, which is what applications actually get. Use a wired connection and close other apps for the cleanest result.
