Subscribing needs an account — your subscription is tied to your login, so your reading access works on any device and survives browser changes. Free, takes a minute:
Founding-member price, locked in while you stay subscribed — when the list price rises, renewals keep your rate. Prices exclude tax, which depends on your location and is calculated at checkout. Cancel anytime; access runs to the end of the paid period. Prefer owning a copy? Every book is also sold individually on Leanpub — buy once, keep every future update of that book. The first chapter of every book stays free to read either way.
