Guided Firmware Selector
Quick answer
The Guided Firmware Selector is a five-question wizard that recommends ASIC mining firmware for your hardware and goals. It matches Bitaxe boards to open AxeOS, and S19/S21-class Antminers to per-chip autotuning firmware such as BraiinsOS+ — the open path to Stratum V2 — or commercial VNish and LuxOS. Dev fees are ranges; flashing carries brick risk.
Answer five short questions and this guide will point you toward a firmware path that fits your goals — with an honest rationale. Custom Antminer firmware builds on the work of projects that opened this space; this tool simply helps you find a sensible starting point. It is educational, not a guarantee — always confirm support for your exact control board before flashing, and remember flashing custom firmware is done at your own risk.
Dev-fee figures are ranges quoted as hashrate and can change — check each project’s current terms. Feature notes are grounded in D-Central’s Mining Bible research and reflect publicly documented firmware behaviour as of June 2026.
