SessionSync

E2E encrypted cross-device browser session sync. No registration required.

SessionSync lets you sync your browser login sessions across devices with one click — fully end-to-end encrypted, no registration required. HOW IT WORKS • Generate a random sync key (120-bit entropy, high cryptographic strength) • Click "Push" to encrypt and upload your current session (cookies + localStorage) • On another device, import the same key, open the same site, click "Pull" to restore SECURITY • AES-256-GCM encryption with PBKDF2 key derivation (600K iterations) • All encryption happens locally in your browser — the server only stores ciphertext • Write-protected: every write is verified with a cryptographic write token • No accounts, no emails, no tracking FREE PLAN • Sync up to 3 sites for free PRO PLAN • Unlimited sites — pay once, yours forever OPEN SOURCE • Fully transparent, auditable code: https://github.com/tageecc/session-sync • Self-hostable with your own Supabase backend
