All the other comments are focusing on the Apple angle, but I want to comment on how amazing the developer, Riley, is.

I've seen him working on this project (Delta and the AltStore) for four or five years. It's a project he's passionate about, and he's building it for himself, not to try and make money. (In fact, he's turned down offers from startups and top tech companies to work on this). More than almost anyone else I know, Riley embodies the classical hacker ethos. I believe partway through the project he decided to make this open source, so he then went back and re-factored a lot of the code to make it easier to learn from.

Here's the repository, btw: https://github.com/rileytestut/AltStore

That is good. But I have question when he started on Altstore Is he working on Altstore for 4-5 years? I do not think it was possible 4-5years before.

I think apple release free signing without Apple Developer Account in July 2016.

Must have misunderstood, he had the initial commit for AltStore this May. It's Delta he's talking about.
