I am doing some thing new this past weekend, it is not polished and open-sourced yet, but would like to share it a little bit, it is called PingKey, a kind of replacement for linktree but minimal limited with clean interface.

PingKey works like a contact card, or rather just a way to let other people reach you without requiring email, phone number or any social network accounts.

You can leave a message to PingKey's CEO here https://www.pingkey.xyz/p/87b915fff950d6683f449edb8d283c04ac789c506daf49dbdbd97b344e5db383 to ask question, participate in the early days, make suggestions...
