Status: Stable, functional, ultra-minimal

TorFrog v1.7.0 – Nuclear Minimal Build

This version represents the first stable, fully–featured, ultra-compact release of TorFrog, a tiny BitTorrent client built on top of libtorrent-rasterbar, written in C++20 with a focus on minimalism, portability, and extremely small binary footprint.

Highlights

  • Fully functional BitTorrent client in ~15 KB, using dynamic linking and aggressive compiler/linker optimization.
  • High-performance, flicker-free ASCII TUI with progress bar, ETA, speed metrics, peers count, and sparkline graphs.

Major Engineering Changes

  • Replaced all standard output with raw write() system calls (no <iostream>, no streams).
  • Removed exceptions, RTTI, unwind tables, and heavy C++ runtime features.
  • Eliminated <filesystem>, <deque>, and other size-heavy standard library components.
  • Dynamic string concatenations removed from the render loop; replaced with fixed-size stack buffers.
  • Implemented fixed-size history buffer for download-rate sparkline (zero allocations).
  • Consolidated screen rendering into a single atomic write per refresh cycle.

UI and UX Improvements

  • Strict ASCII-only interface (no Unicode glitches on any terminal).
  • Stable fixed-width progress bar with percentage and ETA.
  • ASCII sparkline for real-time download trends.
  • Color mode can be toggled (--no-color).
  • Screen clearing can be toggled (--no-clear).
  • Sequential download mode enabled by default (--seq / --no-seq).

CLI Features

  • Magnet links and .torrent files supported.

  • Customizable:

    • download directory (--save)
    • rate limits (--max-down, --max-up)
    • bar width (--bar-width)
    • tracker disabling (--no-trackers)

  • --help and --version included.

Optimized Build Pipeline

Aggressive size-oriented flags, including:

  • -Oz, -fno-exceptions, -fno-rtti
  • -ffunction-sections -fdata-sections
  • -fno-unwind-tables -fno-asynchronous-unwind-tables
  • -Wl,--gc-sections --icf=all --as-needed --build-id=none
  • -s for maximum strip

Result

TorFrog v1.7.0 achieves:

  • extreme binary compactness,
  • no dynamic allocations in the rendering path,
  • a clean, stable UI,
  • full libtorrent functionality,
  • and remarkably low CPU and memory usage.
