  ## [Production apps in development]
  - @TODO
  ## Both Frontend & Backend
  -MoonZoon apps have been deployed to [Heroku](https://www.heroku.com/) ([buildpack](https://github.com/MoonZoon/heroku-buildpack-moonzoon)), [Clever Cloud](https://www.clever-cloud.com/) and [CapRover](https://www.clever-cloud.com/). [DigitalOcean App Platform](https://www.digitalocean.com/products/app-platform) is planned. However, no solution was simple enough. That's why we need [MoonZoon Cloud](docs/cloud.md). But I plan to include `Dockerfile` soon so we have other options in the meantime. Please, write to [chat](https://discord.gg/eGduTxK2Es) when you have some questions regarding deployment.
