Speedtest by Ookla
An internet speed test for measuring download, upload and latency in the browser or apps.
Replacements
Listings that take over the same core job as Speedtest by Ookla.
FAST.com
A minimal browser speed test that estimates your download speed in a few seconds.
FAST.com gives a quick download figure in the browser, but it hides upload and latency by default and does not measure jitter or packet loss.
Cloudflare Speed Test
A browser-based internet speed test that measures throughput, latency, jitter and packet loss.
Cloudflare Speed Test runs in the browser and adds jitter, packet loss and quality scores, but it measures only the path to Cloudflare's network.
nPerf
Internet speed test measuring download, upload and latency, in the browser and as apps.
nPerf also has browser and app versions and adds streaming and browsing tests plus a coverage map, testing against nPerf's own servers only.
M-Lab Speed Test
A browser speed test from Measurement Lab that publishes its measurement data openly.
M-Lab Speed Test uses openly licensed methods and reports retransmission, but it publishes your IP address with the results in a public dataset.
LibreSpeed
Self-hostable speed test with no Flash, Java or Websocket.
LibreSpeed is open source under LGPL-3.0 and self-hosted, so it measures the path to your own server rather than a public test server.
OpenSpeedTest
HTML5 speed test that can be self-hosted from a Docker image.
OpenSpeedTest is an open-source HTML5 test you can self-host with Docker, suited to LAN throughput but capped below dedicated tools.
Waveform Bufferbloat Test
Browser test that measures internet speed and how latency rises under load.
Waveform Bufferbloat Test runs in the browser and focuses on how latency rises under load, rather than offering apps and result history.
Speedtest CLI
Official Ookla speed test for the command line.
Speedtest CLI is Ookla's official command-line client with JSON and CSV output, licensed for non-commercial use by default.
Similar software
Related functionality, not a direct replacement.
iPerf3
Measures how fast a network link really is between two machines you control, which a speed test cannot.
Flent
Network benchmarking tool that runs repeatable tests with netperf and iperf and plots the results.
Downdetector
A website that shows whether online services, networks and games are down, based on real-time user reports.
Globalping
A free service for running ping, traceroute, DNS, MTR and HTTP tests from probes worldwide.
gping
Ping with a live graph, so you can see latency spikes and packet loss instead of reading a column of numbers.
