Replacements

Listings that take over the same core job as Waveform Bufferbloat Test.

  • Cloudflare Speed Test

    A browser-based internet speed test that measures throughput, latency, jitter and packet loss.

    FreeProprietaryWeb

    Cloudflare Speed Test also runs in the browser and reports jitter, packet loss and loaded latency, but sends your IP to Cloudflare.

  • FAST.com

    A minimal browser speed test that estimates your download speed in a few seconds.

    FreeProprietaryWeb

    FAST.com shows loaded and unloaded latency on request, but hides it by default and measures no jitter or packet loss.

  • Speedtest by Ookla

    An internet speed test for measuring download, upload and latency in the browser or apps.

    Speedtest by Ookla adds apps and result history for download, upload and latency, with less focus on latency under load.

  • M-Lab Speed Test

    A browser speed test from Measurement Lab that publishes its measurement data openly.

    FreeProprietaryWeb

    M-Lab Speed Test reports retransmission and publishes open data, but retains and publishes your IP address with results.

  • nPerf

    Internet speed test measuring download, upload and latency, in the browser and as apps.

    nPerf measures download, upload and latency in the browser and in apps, adding streaming and browsing tests on desktop, against its own servers.

  • LibreSpeed

    Self-hostable speed test with no Flash, Java or Websocket.

    LibreSpeed is an open-source, self-hosted speed test, so results measure the path to your own server rather than a hosted service.

  • Flent

    Network benchmarking tool that runs repeatable tests with netperf and iperf and plots the results.

    Flent runs repeatable latency-under-load experiments with plots on Linux, but needs netperf or iperf and a test server at the other end.

Also worth comparing

These listings name Waveform Bufferbloat Test as their own alternative, so the relationship runs both ways.

  • OpenSpeedTest

    HTML5 speed test that can be self-hosted from a Docker image.

    Waveform Bufferbloat Test adds latency-under-load measurement in the browser, but it is a hosted closed service on a retailer's site rather than self-hosted.
