Capsule - Easy File Transfers

About Capsule is the fastest way to move a file between devices or people without giving it a permanent home. Upload from the browser, terminal, or Android app and share a link built from three readable words, like raven-quiet-summit. You can say it out loud across a room. An hour later, the file is gone from our servers. Nothing to clean up, nothing left behind. Key features - True end-to-end encryption in every client: web, CLI, and Android. Files are encrypted on your device using the age format with a BIP39 mnemonic passphrase, and the server only ever stores ciphertext. - Fully interoperable clients. Encrypt on your phone, decrypt in your terminal, or the other way around. - A polished CLI with progress bars, QR codes, and shell completions. Install via Homebrew, COPR, Scoop, or one curl command. - Native Android app with share-sheet integration, QR scanning, and upload history. - Open source, AGPL server you can self-host, and every client can point at your own instance. What makes it different No accounts, no email walls, no "free tier" nag. Most transfer services encrypt in transit but hold the keys themselves. Capsule can't read your files even if it wanted to, and deletion after one hour is the default behavior, not a paid setting. What you can expect Get a shareable link in seconds. Move files between your phone and laptop without cables or cloud accounts. Send something sensitive knowing exactly who can open it and exactly when it stops existing.
