can't install Heroku on Mac, any solution?

Hey Guys,

I created NodeJS API and trying to deploy to Heroku as it is the only free hosting platform ( free sign up with no CC), no aws pls (sign up required with CC). However am facing issues while installing through installer and CLI. Is there a solution for this? If not, can someone share if there is any truely free platform to host APIs ( now aws, gcp etc.. pls)

Error -

“heroku.pkg” can’t be opened because Apple cannot check it for malicious software.

From Forums - Heroku is aware of this issue and is working on it. From their website: https://devcenter.heroku.com/articles/heroku-cli#download-and-install

Currently, the macOS installer on Catalina displays an “unknown author” warning. We are working to address this.

Try running this command in your terminal instead:

brew tap heroku/brew && brew install heroku

Thanks much, appreciate your help.
