Used to being coerced into using clunky mobile apps for this sort of service. Quite refreshing to see a first-class browser experience here.

The sign-up and phone number acquisition flows were seamless. Excited to try calling now!

Remarkable work - thank you!

It's idiomatic in Kotlin as well!

You're gonna absolutely love up (https://github.com/akavel/up).

If you pipe curl's output to it, you'll get a live playground where you can finesse the rest of your pipeline.

Built a CLI¹ a couple of years back that uses HashiCorp Vault's implementation of the Shamir Secret Sharing algorithm and exposes its functionality to the command-line.

Here's a CLI, written in Go, that uses HashiCorp Vault's implementation of the Shamir Secret Sharing algorithm and exposes its functionality to the command-line in an easy-to-use manner.

I personally use it to divide my password manager's master password into shares that are given to family members and close friends in order for them to collectively reconstruct my master password and obtain access to my password vault in case I pass away.
