SERVER DATABASE — 2,100 free test servers. Strategy: seeded anchor cities,
multiple ISP/DC
nodes per city,
spread
across every continent/region. Shown to user nearest 8 only.
NetPulse is a free browser-based internet speed tester built by DevspireHub. It connects to
the nearest server and runs a live
test to show how fast your internet connection really is — including download speed, upload speed, ping, jitter,
and
packet loss.
How does it work?
Click "Start Test" — NetPulse automatically detects your location and selects the best
nearby
server using geo-sorted proximity, so you
always get the most accurate result for your region.
Your IP and ISP are identified — tNetPulse detects your public IP address, ISP name, and
city automatically. No manual input is needed.
Ping is measured first — NetPulse sends multiple requests to the server and measures how
long the response takes. This is your connection's
reaction time in milliseconds.
Jitter is calculated — The variation between consecutive ping samples is measured to
check how stable your connection is under real conditions.
Download speed is tested — NetPulse measures how fast data flows from the server to your
device using multiple parallel streams for an accurate,
real-world reading.
Upload speed is tested — Your device sends data back to the server. This measures how
fast your connection can transmit, which affects video
calls, gaming, and cloud uploads.
Packet loss is checked — NetPulse detects whether any data packets are being dropped,
which causes buffering, lag, and call quality issues.
Live charts update in real time — A live throughput chart and ping/jitter graph update as
the test runs, giving you a visual picture of your connection's
performance over time.
Results are saved — Your last test results are stored locally so you can review and
compare your connection's performance over time.
What the Results Mean
Download Speed: How fast you receive data from the internet. This affects streaming, web
browsing, video playback, and file downloads.
Higher is better.
Upload Speed: How fast your device sends data to the internet. This affects video calls,
live streaming, cloud uploads, and online
gaming. Higher is better.
Ping: The delay between your device and the server in milliseconds. Lower ping means a
more responsive connection. Under 20 ms
is excellent for gaming and video calls.
Jitter (ms): The inconsistency in your ping over time. High jitter causes choppy
audio/video in
calls and unstable gameplay even if
your average ping looks fine. Lower is better.
Packet Loss (%): The percentage of data packets that fail to reach their destination. Any
packet loss above 1% will noticeably degrade
call quality, streaming, and gaming. 0% is ideal.

Why Use NetPulse?
Most speed test tools are cluttered with ads, require app installs, or give inaccurate results. NetPulse is
different —
it's lightweight, open-source, and built for accuracy. Here's why users choose NetPulse to test their internet
connection:
Geo-sorted nearby servers — NetPulse detects your location and automatically ranks
available servers by proximity, so your test always uses the
closest and most relevant server.
Real-time live charts — Watch your download, upload, ping, and jitter plotted live as the
test runs — not just a final number at the end.
Multi-metric analysis — Your public IP address and ISP name are detected automatically
and shown on screen alongside your test results.
Auto IP & ISP detection — Auto IP & ISP detection
No ads, no installs — NetPulse runs entirely in your browser. No sign-up, no extension,
no app required.
Test history — Your recent results are saved locally so you can track your connection
quality over time without creating an account.
Open-source & transparent — The full source code is publicly available on GitHub, so you
can verify exactly how every measurement is made.
Works on any device — Fully optimized for desktop, tablet, and mobile with a responsive
dark-theme dashboard that looks great on any screen
size.
