Link shortener in Rust.

Developed to be as minimalist and lightweight as possible.

Powered by the Actix framework using (server-side) Askama templates.

  • Around 1000 lines of code, including 20% of comments
  • Consumes between 5MB and 20MB of RAM
  • No JS
  • No CSS framework ; CSS is handmade and all rules are prefixed to avoid rule conflicts
  • No tracking features at all, user IPs are not saved in database
  • No unsafe block
  • Compiles on Rust stable


  • Includes a captcha as a minimal protection against spamming
  • Easily customizable assets, contact details, and hoster information
  • Light / dark theme
  • Only needs a SQLite database to work
  • Robust caching features to serve content even with database locks
  • Localization (available in French and English, please translate!)
  • Basic protection against spambots (captcha with a customizable difficulty)
  • Active detection of phishing links (detects "suspicious activity")
  • Counting clicks
  • Allows shortcut deletion by the user
  • Allows marking a shortcut as "phishing", which displays a awareness-raising message to victims

Running an instance

First, you must install Cargo and the latest stable version of Rust by following the instructions on this website. Alternatively, you can use the liuchong/rustup Docker image.

  • Clone the project:
git clone
  • Edit what you need. You might want to change the following files:

    • assets/hoster-logo.svg: replace with the logo of your organization
    • assets/logo.svg: the software logo
    • assets/themes/light/background.jpg: the default background for the light theme
  • Copy config.toml.sample to config.toml and edit its values to suit your needs:

    • Important: Replace default values of cookie_key and phishing_password.
  • Edit blacklists at your convenience.

    • url_from_blacklist.list: Any client that submits a link name fully matching one of the elements in this list will get a 403 Forbidden HTTP status code.
    • url_to_softblacklist.list: Any client that submits an URL containing one of the elements in this list will get denied with a friendly warning.
    • url_to_blacklist.list: Any client that submits an URL containing one of the elements in this list will get a 403 Forbidden HTTP status code.

You can configure a fail2ban instance and watch your favourite reverse-proxy logs to see which IPs are getting a 403 and ban accordingly for the duration of your choice.

  • cargo run --release


Here are many ways to contribute:

  • Translate!
    • Add your entries in the lang.json file.
    • Once you're done, edit and add your language in the ValidLanguages structure.
  • Add PostgreSQL/MySQL compatibility (easy thanks to Diesel)
  • Add some more CSS themes
  • Rework default themes' CSS (they've gone a bit messy since then. hopefully they are commented)
  • Develop a more resilient protection to spambots
    • Add JS? :(
  • Add a toggle to disable the captcha
  • Experiment around captchas to match accessibility needs. I have no idea... :(

This software is mainly developed and maintained by Neil for the Association 42l.
