DTails is an open‑source remastering tool for Debian Live‑based operating systems, such as Tails, a privacy‑focused OS designed for security and anonymity. Using a straightforward GUI, it opens a stock ISO, lets users add or remove Bitcoin and privacy software such as Sparrow Wallet, Liana, Bisq, SeedTool, Specter Desktop, and more, then rebuilds a bootable ISO in minutes with no persistence required. By automating package selection and ISO assembly, DTails removes barriers to running hardened Bitcoin toolsets on Tails.
