SPXP is a decentralized protocol for social profiles. No algorithms. No central authority. No data harvesting. You own your profile.

}Current social networks are broken. They optimize for engagement, not for you. SPXP puts control back where it belongs.
Your client decides what to show. No engagement-optimized feeds. No filter bubbles. No manipulation.
Private posts are encrypted with your keys. Servers can't read your content. Even metadata is protected.
Host your profile anywhere. Your web server. Your Raspberry Pi. Any hosting provider. Move anytime.
Ed25519 signatures prove authenticity. Nobody can forge your posts or tamper with your profile.
Built on HTTP + JSON + proven crypto standards. No blockchain. No tokens. Just the web.
Open source. Open spec. Build your own client, server, or service. No permission needed.
Profiles are JSON files served over HTTPS. Clients fetch and display them. That's it. No magic. No complexity.
Write a JSON file with your info. Add a keypair for signing.
Upload to any web server. GitHub Pages, Netlify, your own box.
Your profile URL is your identity. Share it, link it, own it.
Exchange keys to unlock private content. E2E encrypted connection handshake.
