Heroku CLI now supports REPL and Prompt mode

Change effective on 17 September 2025

The Heroku CLI now supports Read-Eval-Print Loop (REPL) and prompt modes:

  • The Heroku CLI REPL feature provides an interactive environment to run Heroku CLI commands without typing heroku each time. Run multiple commands faster by setting and persisting flags and more. Run heroku --repl to start the environment.

  • The Heroku CLI Interactive Prompt helps you run Heroku CLI commands by guiding you through the required inputs. Add --prompt after any command when you’re unsure about what required or optional arguments and flags a command uses.
