Test your real internet speed, see how VPN affects performance, and detect hidden lag problems like bufferbloat. This tool explains every metric in plain English so you know what affects streaming, gaming, video calls, browsing, and VPN use.

Choose the right mode

⚡Quick Test
Open

Fastest way to check whether your internet feels healthy right now. Best before a call, stream, or download when you want a quick answer without deep diagnostics.

🧪Deep Test
Open

Use this when games lag, calls glitch, or buffering appears only under load. It exposes jitter, loaded latency, and hidden router or Wi‑Fi congestion.

🧭Baseline
Open

Save your no‑VPN reference first. Then you can compare the same line against a VPN run and see the real penalty in speed, ping, and stability.

🔒VPN Compare
Open

Best when you already saved a baseline. It shows whether the slowdown comes from the VPN server, protocol, distance, or your own connection.

-- Mbps Ready
-- Ping ms
-- Jitter ms
-- Down Mbps
-- Up Mbps

After your test

Compare with a proven VPN only after you know your baseline

Use these only after you finish the tool. That way you compare a real problem against a real reference, not marketing claims.

NordVPN

Verified speed pick

One of the most reliable choices when you need high throughput with low latency. Good default option for gaming, streaming, and “how much speed do I really lose on VPN?” checks.

  • Fast global routing with consistently low ping on nearby regions
  • Strong WireGuard-based performance for 4K streaming and large downloads
  • Large server coverage, so it is easier to compare close vs distant locations

Surfshark

Best speed/value

Good option when you want strong speed without overpaying. Useful for home setups with many devices and for checking how much VPN overhead appears on shared Wi‑Fi.

  • Fast WireGuard performance and solid streaming stability
  • Unlimited devices, useful when the same line is shared by phone, TV, and laptop
  • Usually a strong price-to-speed tradeoff for daily use

Proton VPN

Stable EU routing

Strong privacy-focused option with stable European routing. Good when you care about predictable behavior, not just raw headline speed.

  • Reliable latency on EU routes and good congestion handling
  • Useful for comparing “privacy-first” routing against gaming-first speed profiles
  • Good benchmark when testing VPN impact on browsing and video calls
