SEAL

Send a file or folder without creating an account. SEAL encrypts web uploads in your browser. Start at seal.net: click "Tap to send", choose a file, set access rules and create a sharing link. Control expiry, passwords, single-use access, opening limits, geographic restrictions and NDA-gated access. Keep the separate management link to add files, create links to selected files, view access activity, export a signed log or revoke future access. Recipients can download individual files or a ZIP. Revocation cannot remove copies already downloaded. SEAL Box is a browser inbox for your transfers, incoming files and requests from agents. Create an inbox without email and save its recovery key. Connected agents can deliver files there; you can answer their file requests outside chat. Telegram users can use @Sealnetbot and its Mini App. Direct bot-chat uploads pass through Telegram and the bot host before encryption; the Mini App and seal.net encrypt on the device. Developers have CLI, SDK, HTTP API and MCP workflows. Current packages are sealnet-mcp for MCP and sealnet for JavaScript and Python; the official Claude Code plugin and skill are at github.com/seal-hq/claude-plugins. Agent requests return a local file path rather than pasting a secret into chat. Recipient-key transfers support addressed handoffs. Host permissions still matter: a path does not prevent a process from reading the file. Free: up to 1 GB per seal for up to 7 days. One-time upgrades per seal: 5 GB/$9/3 months, 50 GB/$29/6 months or 500 GB/$99/12 months. The separate per-file limit is 10 GB, not the free allowance. See seal.net/pricing. Slack and browser extensions are Coming soon. Setup and security details: seal.net/docs and seal.net/legal/security.
