CGMiner v4.12.1

12 MBupdated 2026-08-15 ★ 4.3FreeMining

CGMiner is an open-source mining application written in C that works with graphics cards and ASIC devices. It is configured through command-line flags or batch scripts, runs in a terminal window, and is commonly used on rigs that are managed remotely without a graphical interface.

The miner exposes a local API that monitoring tools can query for hashrate, accepted shares, and device temperatures. Because the source is published and auditable, administrators running headless farms often keep it as a baseline reference implementation.

What's inside

  • Open-source C implementation
  • Support for GPU and ASIC devices
  • Configuration through flags and batch scripts
  • Local API for monitoring software
  • Failover pools and share tracking
  • Low overhead on headless machines

How to install
