browser dialogs never
looked so good

Fork me on GitHub Native browser dialogs versus alertify.js dialogs

The end of maintenance... at least for now

Unfortunately, I will no longer be maintaining alertify.js. I have many ongoing projects that aren't leaving me with enough time to do what needs to be done. If anyone wants to create a fork and maintain - by all means go for it!

It's been great seeing people use it and enjoy it and this decision is simply because I don't believe it's fair that developers are looking for help and not getting it.

I wish I had more time or contributions to keep it going and make it better, but the sad reality is that not usually the case on these kinds of projects.


I will be updating this site to list forks of alertify.js. At this time none are the official successor, I will leave the community to decide which one should become the main repo. If you have a fork and are interested in taking over alertify.js, please send me a note.
