You need to have Node.js, PostgreSQL and Redis installed.

  1. Clone this repository or download the latest zip.
  2. Copy .example.env to .env and fill it properly (see below).
  3. Install dependencies: npm install.
  4. Run for development: npm run dev.
  5. Run for production: npm run build then npm start.


  1. Download the docker-compose.yml and the .docker.env files.
  2. Rename .docker.env to .env and fill it properly (see below).
  3. To execute Kutt you simply have to run docker-compose up -d command and then the app should be ready on port "3000".

The docker-compose.yml uses the official kutt docker image available on Docker Hub.


For the minimal configuration the following settings have to be changed in the .env-file:

  • DEFAULT_DOMAIN: The domain of your kutt instance
  • DB_: The DB credentials (when you use docker-compose you can skip these)
  • ADMIN_EMAILS: A comma-separated list of the administrator-accounts
  • RECAPTCHA_: Enter your credentials to use reCaptchas or delete this setting if you don't want to use it
  • MAIL_: Enter the SMTP-server's credentials (The experience shows SSL works better than STARTTLS; The mail config is required to easily create accounts, see this comment how it can be done manually)
  • REPORT_EMAIL: Kutt offers a form to report malicious links which are sent to this mail-address
