A curated list of awesome Pubky resources, libraries, tools and applications. Pubky is an open protocol for per-public-key backends for censorship resistant web applications.

What is Pubky?

Pubky is an open protocol that pairs cryptographic keypairs (used as identities) with user-controlled home servers. Users own their identity and choose where their data lives, instead of relying on a single platform.

Where to start

Start with pubky.org for the canonical project overview, then docs.pubky.org for the protocol specification and developer guides. Pubky.app is a working app stack you can sign in to today. If you’re curious about how pubky keys map to DNS, PKDNS resolves DNS records published under public keys, so a pubky works as a domain name.

This list tracks libraries, SDKs, apps, and tooling built around the protocol — both official and community.
