pomf backend written in crystal for



  • Postgres
  • Mschematool
  • Crystal 0.19.4


Set your environment variables:

  • POMF_PORT - The port that cpomf listens to.
  • POMF_DEBUG - Whether or not cpomf is in debug mode true|false
  • POMF_DATABASE_URL - The postgres URL for your database, eg; postgres://localhost/pomf_database
  • POMF_SECRET_KEY - Your secret key; preferably something that's long and randomly generated.
  • POMF_ADMINS - A comma seperated list of admin usernames; keeping in mind that usernames are lowercase and alphanumeric only.
  • POMF_BLACKLISTED_NAMES - A comma seperated list of banned usernames; it's usually good to blacklist names like admin or anything else you don't want users to use.
  • POMF_UPLOAD_DIR - Relative path to your pomf upload directory.
  • POMF_UPLOAD_URL - The upload URL for your site; eg.

Configure with accurate postgres settings.

Run shards install to install dependencies.

Run mschematool default init_db and then mschematool default sync

Compile the project with crystal build --release


Run cpomf like you would run any other binary file ./pomf

Use a nginx reverse proxy to cpomf; and use nginx to handle static files, including those in /src/pomf/public; google tutorials if you need to.

Please make sure that you modify the default templates and styles before you host your own clone; I've left' designs in as a reference, but being unique is king in a sea of clones.
