What is it?

wastebin is a self-hosted pastebin for sharing text snippets, logs and code through a browser or an HTTP API. It is built on axum with an SQLite database and ships as a single binary with a small memory footprint. Pastes are compressed with zstd, and syntax highlighting covers more than 170 languages via syntect.

Pastes can be encrypted with ChaCha20Poly1305, using argon2-hashed passwords, and set to expire, to be deleted after the first read, or to be removed by the anonymous owner who created them. Markdown pastes can be rendered as HTML with GitHub-flavored tables, task lists and admonitions, and raw HTML is sanitized with ammonia. The interface offers nine color themes in light and dark modes, and a QR code for opening a paste on a phone.

The project does not include user accounts, admin functions or arbitrary file uploads, and the README advises placing it behind a rate-limiting reverse proxy if exposed to the internet. Configuration is handled through environment variables, and a bundled wastebin-ctl tool can list, purge or delete entries directly in the database.

Key features

  • 01Axum and SQLite backend distributed as a single binary
  • 02zstd compression and syntax highlighting for over 170 languages
  • 03Markdown rendering with tables, task lists and admonitions
  • 04ChaCha20Poly1305 encryption with argon2-hashed passwords
  • 05Expiration, burn-after-reading and owner-based deletion
  • 06Nine color themes in light and dark mode, plus a QR code view

Use cases

  • Sharing code snippets or logs with teammates on a private server
  • Pasting command output from a terminal via curl or a shell function
  • Sending temporary encrypted notes that expire or self-destruct after one read
  • Hosting a small internal pastebin with Docker or docker-compose

Quick start

  1. 1

    Install a Rust 2024 toolchain (Rust 1.85 or newer) with rustup

  2. 2

    Build and run the server in release mode with cargo

    cargo run --release

Things to know

  • It has no user authentication or admin functions, and the README advises against exposing it to the internet without rate limiting or a reverse proxy.
  • The default database path is in memory, so pastes are lost on restart unless WASTEBIN_DATABASE_PATH is set.
