Secret — Secure, Zero-Knowledge Encrypted Note & File Sharing

Share passwords, notes, and files securely with end-to-end encryption. Your data is encrypted in the browser using XChaCha20-Poly1305 — the server never sees your content. Self-hosted with a single Docker container. No accounts, no analytics, and no content, keys or IP addresses in the logs.

A modern, open-source alternative to PrivateBin, OneTimeSecret, and Yopass — built with Svelte 5, Hono, and TypeScript.
