not-th.re is a lightweight paste and file sharing platform focused on simplicity and client-side encryption. It provides a modern editor experience and tools to host a private instance or use the public UI.

Key Features

  • Client-side end-to-end encryption: data is encrypted in the browser before being sent to the server
  • Monaco-based editor with syntax highlighting and dark mode
  • Simple paste sharing and encrypted file transfers
  • CLI and SDK to upload, download, encrypt, decrypt and query notes programmatically
  • Can run as a minimal API-only service or as a full stack (API + UI) via Docker images
  • Integration with Excalidraw for drawings and planned features like peer-to-peer sessions and note bundles
  • No tracking, no cookies, and no ads by design

Use Cases

  • Securely share code snippets or notes that remain encrypted until opened by recipients
  • Transfer and store small encrypted files between collaborators without third-party storage
  • Integrate paste and secret-sharing into automation or developer tooling using the CLI/SDK

Limitations and Considerations

  • No built-in user accounts or server-side key recovery; if encryption keys are lost, data cannot be recovered
  • Micro deployment mode does not include a hosted UI; it requires either the public UI or hosting the UI separately
  • Intended for short-lived pastes and small file transfers rather than large-scale file storage or full collaboration suites

not-th.re is best suited for users and teams that need a minimal, privacy-first paste and file sharing tool with client-side encryption and programmatic access. It is easy to deploy with Docker and offers a CLI and SDK for automation and integration.
