Scalafmt vs Taplo
Both stand on code formatting tools. Which one you can start free with, which one lets you read the code, and what each costs once you pay.
Free plan LinuxMacSelf-hosted+1
Choose Scalafmt if you need a free, open-source formatter for Scala projects and want to run it through editors, builds, or the command line. Its main caveat is IntelliJ range formatting, which defaults to IntelliJ’s formatter and may not suit Scalafmt’s whole-file approach.

Taplo brings TOML validation, formatting and queries into a free toolkit with multiple installation options. Note the language server's build and NPM limits, and the preview status of its Visual Studio Code extension.
