We have always loved to use bitaddress.org for securing our Bitcoin offline. It is a great tool for cold storage and a big thank you from our side to the author(s).
However, it seems like the development of bitaddress.org has come to a halt which has lead to the lack of support for new Bitcoin features (most notably SegWit Addresses).
There are other generators out there like https://segwitaddress.org/ but they do not come close to the scope of features offered by bitaddress.org.

This lack of comprehensive yet up-to-date paper wallet generators has bothered us to the point where we decided to develop a tool ourselves.
With this in mind, we would like to introduce you to our implementation for a possible bitaddress.org successor:
https://coinglacier.org

The major differences are the new Bitcoin features that coinglacier.org supports:

SegWit and Bech32 Support
Hierarchical Deterministic (HD) Wallets
(password-protected) Mnemonics
Possibility to show extended public keys
We have changed the additional entropy generation from mouse movements to using the NPM package more-entropy in the background

Besides of that we have maintained the highly appreciated possibility to BIP38-encrypt private keys.
We do this asynchronously using web workers though, so it should be a bit faster for you if you are generating multiple addresses ;-)
Furthermore, we have kept the application as an all-in-one HTML file, so you can easily download the file and run it locally.

Of course you are skeptic at this point about whether you may trust our software or not.
We appreciate your skepticism it's a good thing to be skeptical in this space.
The good point is, coinglacier.org is fully open source and available on Github, so:
Don't Trust. Verify.

This is just the start of the development, we still have a lot of ideas to implement!
So if you want to support the further enlargement of the glacier, consider a donation to one of the following addresses:

Coinglacier.org is safest when you open the HTML file locally (from an offline computer if possible).
For a safe installation, please follow the instructions on the Github readme:
https://github.com/dalitsairio/coinglacier.org

The watch-only wallet Sentinel is a great complement to coinglacier.org cold wallets and works best when you scan your extended private key(s).
This will then allow you to

Have an overview about your balances
Sweep BTC from other private keys onto your cold storage

and all this while not losing the security of a cold wallet.

Comments, criticism, pull requests, feedback and donations are welcome.
More documentation and features will follow.
