Ready to test

Test if your internet is actually good enough

Run a quick browser-based diagnostic for calls, gaming, streaming, VPN, and remote work. Verdicts appear before raw technical numbers.

Measured from your browser to the nearest Cloudflare server with Cloudflare’s open-source speed test engine, so results reflect your connection to Cloudflare, not every site you use. Uses roughly 20–190 MB of data, more on faster connections, so use Wi-Fi if you are on a metered plan. Results are not sent back to Cloudflare. How we measure

Jitter test for connection stability

Jitter explains why a connection can feel choppy even when average ping looks fine. It is especially important for real-time audio, video, and gaming.

Why jitter matters

Real-time apps need network timing to be predictable. Large swings in latency can cause buffering, audio gaps, delayed input, and inconsistent video quality.

How to reduce jitter

Use wired Ethernet where possible.
Pause uploads and cloud backups.
Move closer to the router or use a cleaner Wi‑Fi channel.
Upgrade old routers that struggle under load.

Frequently asked questions

What is jitter?

Jitter is the variation in latency from one moment to the next. Low jitter feels smooth; high jitter creates stutter and instability.

What is good jitter?

For video calls, below 10–15ms is good. For gaming, lower is better, ideally below 5ms.

Can high jitter happen with fast internet?

Yes. Fast download speed does not prevent Wi‑Fi interference, router queueing, or ISP congestion from causing jitter.
