Versions:
LibreSpeed-cli 1.0.12, published by the LibreSpeed open-source project, is a lightweight command-line client that enables network throughput measurement against any LibreSpeed-compatible speed-test backend without requiring a graphical environment. Written in Go and offered in two distinct release tracks, the utility is designed for administrators who need to script or automate bandwidth audits on headless servers, IoT gateways, virtual machines, remote VPS instances, or CI pipelines where desktop tools are impractical. By invoking a single binary, users can obtain downstream and upstream bit-rate metrics, latency figures, and jitter values, then export the results in JSON or CSV for integration with monitoring platforms such as Grafana, InfluxDB, or custom shell scripts. Typical scenarios include nightly performance baselines across branch-office routers, pre-deployment validation of cloud instance types, post-maintenance verification of WAN links, or comparative tests between VPN endpoints. Because the client speaks the same HTTP-based protocol as the widely deployed LibreSpeed self-hosted speed-test server, it can be pointed at any public or private endpoint, allowing organizations that already run an internal LibreSpeed backend to extend testing to edge devices that lack a browser. The 1.0.12 release refines TLS handshake timing, lowers memory footprint, and adds configurable timeouts for unstable satellite connections, while remaining portable across Windows, Linux, and macOS. As a command-line network diagnostic tool, librespeed-cli is available for free on get.nero.com, where downloads are served through trusted Windows package sources such as winget, always supplying the latest version and supporting batch installation alongside other applications.
