Release Notes

web-speedtest 1.0.0 Beta 11 — 10 Apr 2026

  • Initial release
  • Server mode — HTTP server with embedded web UI for browser-based speed testing
  • Client mode — CLI tool that measures ping, download, and upload from any web-speedtest server
  • Web UI with animated gauges, dark theme, and live progress
  • Copy test results from the web UI to the clipboard as text or as a PNG image
  • WebSocket ping for low-overhead latency measurement, with HTTP fallback
  • Server-Timing header on the HTTP ping endpoint so the CLI client can subtract server processing time
  • Warmup exclusion (first 2 seconds discarded) for download/upload accuracy
  • Median-based ping reporting for outlier robustness
  • Parallel streams (6) for both download and upload tests
  • Hand-rolled WebSocket implementation (RFC 6455) — stdlib only
  • API endpoints: /api/ping, /api/download, /api/upload, /api/info, /ws
  • Beta ribbon shown automatically on pre-release builds, hidden on full X.Y.Z releases
  • Single statically-linked Go binary with zero runtime dependencies
  • Distributed as platform-specific Python wheels via PyPI (using bin2whl)
  • Cross-platform: macOS, Linux, and Windows on both arm64 and amd64
