Self-hosted network speed test

LibreSpeed 6.3 adds shareable result images and fixes Safari upload tests.

speed-testself-hostedmeasurement-accuracydockersharing
◆Current state
LibreSpeed made its rewritten design the default in 6.0.0, then turned to measurement in the 6.2.x line with a connection-stability test and an upload-inflation fix. 6.3.0 in September added a shared-result image matching the chosen design, SERVER_LIST_URL support in frontend Docker mode, and a fix that puts modern Safari on the standard upload path. 6.3.1 in October fixed mixed-content filtering in server selection and the mobile gauge.
◆Where it's heading
With the design migration done, releases focus on measurement accuracy and easier Docker deployment. Minor versions arrive every month or two.
◆Prediction
Expect further accuracy and deployment fixes in 6.3.x; no larger feature is signalled.

    LibreSpeed 6.3.1

    LibreSpeed 6.3.1 fixes mixed-content filtering in server selection and mobile gauge layout, and republishes the image after PHP security releases (CVE-2026-109618/109619). Mostly maintenance, with a security reason to update container images.

    LibreSpeed 6.3.0: shareable result images, Safari upload fix

    Adds a shared-result image that follows the chosen design, server lists by URL in frontend Docker mode, and moves modern Safari off the IE11 upload workaround for more accurate results.

    Upload speeds no longer inflated by failed requests

    Upload speeds were being reported too high when an upload request returned an HTTP error, because the client started a replacement before the failed request resolved; it now waits for a successful status. For a tool whose entire output is a number, a fix that changes what the number says matters more than its size suggests. The release also lets the modern frontend serve from an unrearranged repository layout.

    Standalone connection-stability test and installable PWA

    6.2.0 adds stability.html — a standalone connection-stability test with live latency metrics, charting, packet-loss tracking, optional alerts, and CSV export — plus PWA metadata so LibreSpeed can be installed from a browser. It also fixes Docker rejecting the default 20 MiB upload chunks by raising post_max_size. The stability test is the notable part: it extends LibreSpeed from a single benchmark run toward monitoring a connection over time.

    Reverts server-list.json default in the classic frontend

    A cherry-picked revert of the classic frontend's default use of server-list.json, shipped as 6.0.1 the day after the new design became the default. Cleanup on the migration rather than a change in its own right.

    The rewritten design becomes the default in 6.0.0

    6.0.0 promotes the rewritten design from an opt-in switch to the default, closing out a frontend rewrite that ran for about two years. It also fixes IPv6 client address reporting behind cloudflared and a PHP version check for geoip2 compatibility. This is the release the whole 5.5.x line was preparing for.
