Humanjava builds sovereign identity tools for the open internet. Three products, one principle: your keys, your data, your name.
We don't build apps. We build infrastructure for sovereign digital life ā on Nostr, on Cloudflare, on open protocols. Every product starts free and grows as you need it. Every piece of data stays encrypted and under your control. And if you ever want to leave, you take everything with you.

npub.bio ā Your Name
Your identity on the open web. Starting at $7/year.
npub.bio turns your Nostr keypair into something you can put on a business card. A human-readable identity that resolves to NIP-05 verification, a Lightning address, a public profile page, and bunker discovery ā all from one name.
But npub.bio isn't just a link-in-bio page. It's a full personal homepage ā articles, projects, social links, a webring of trusted connections ā powered by your Nostr metadata. Think of what MySpace gave people, but you actually own it. Your keypair is the deed.
Bring your own domain when you're ready. Point a CNAME, and npub.bio renders your identity at your address ā alice.bio, vergel.online, whatever you choose. The platform is a service, not a host. You can leave anytime.

NostrKeep ā Your Vault
NostrKeep is where your sovereign identity stores its memories. A managed private Nostr relay and Blossom media server ā zero-knowledge encrypted, so we never see your data. Your keys encrypt everything before it leaves your device. We just store the ciphertext.
Key backups, encrypted documents, medical records, API credentials, AI persona files ā anything worth protecting gets a home in your keep. Built on Cloudflare's global network, with dual-jurisdiction data residency for Canadian and American users.
And if you ever stop paying, you get a three-month grace period to export everything. Your data is always yours ā encrypted blobs you can decrypt locally with your nsec. People are more willing to pay for something they know they can walk away from.
