DELE.TO is a zero-knowledge service for sharing passwords, API keys, credentials, and notes. Secrets are encrypted on your device before they are uploaded, and the decryption key remains in the URL fragment.

No account is required. Create a secret on dele.to and share a link that expires after a chosen time or number of views.

Features

• Client-side AES-256-GCM encryption
• Expiring and single-view links
• Optional password protection
• Structured templates for common secret types
• Per-recipient links, QR codes, and creator revocation
• Redis storage with a local development fallback

DELE.TO Cloud

DELE.TO Cloud provides a managed, dedicated DELE.TO instance with a custom subdomain for users and teams that want an isolated deployment without managing the infrastructure themselves.

CLI

The official DELE.TO CLI creates and opens encrypted shares from your terminal.

# macOS and Linux
curl -fsSL https://dele.to/install.sh | sh

# Open the interactive interface
deleto

# Share text or a file
deleto 'the launch code is 1234'
deleto --file .env --expires 15m --views 1

For Windows installation, configuration, and all commands, see the CLI guide.

Deployment

Choose between a managed dedicated instance or self-hosting.

DELE.TO Cloud

DELE.TO Cloud deploys and manages an isolated instance for you, including a custom subdomain.

Vercel

Deploy and manage your own instance on Vercel:

Local or self-hosted

git clone https://github.com/dele-to/dele-to.git
cd dele-to
corepack enable
pnpm install
pnpm dev

Open localhost:3000. Development uses local file storage by default. For Redis-backed deployments, copy .env.example to .env and configure the required values.

Docker is also supported:

docker compose up --build -d

Security

Plaintext secrets and root encryption keys never reach the server. Anyone with a complete share URL can open it while it remains available, so treat the URL as sensitive.
