Heroku Dyno Switcher

What is this?

A little python project to make your heroku app alive forever without being concerned about dyno hours. You do not need to bother adding a credit card to get more dyno hours. I know this is just a petty trick, but at least, it's useful for me. If you use another service than heroku, or you have credit cards to get your heroku accounts verified, or you don't like what I'm doing, you may stop reading this and leave, thank you.

Mechanism

The main idea is to use two accounts (yeah, you need 2 of them to make this work) with two same apps and shift the dyno every 1st and 15th of a month.
Every 10 mins, the script will check if today is either 1st or 15th of a month. If it's true, then it'll switch the dyno based on the heroku app name, heroku API key, and the process type vars you have entered.
This may make your app restart once more at 1st and 15th of the month though (besides the usual 24h restart in heroku free tier).
Another drawback is that you need to deploy to both apps at first, and whenever there's a change you want to make to the app, you need to deploy to both apps too. Patience is really needed for that.

How?

Before you use this, know that I am dumb and not good at python. When I tested it, it worked. But problems may occur whenever, so please, if you have time, check my code in script.py. That will be highly appriciated.

What to do first?
You need to deploy two similar apps to two heroku accounts and only enable the dyno of the primary app.

Where to deploy/run this?

• Another heroku account (add additional variables later by yourself)

• Railway (deploy via GitHub)
• Any PaaS hostings or always-on python hostings
• Your own RDP/VPS

Required Variables

• FIRST_PROCESSTYPE is the process type of your app, you can use web, worker or something else. Check it in the Resources tab of your heroku app.
  
• FIRST_A_APPNAME is the app name of your primary app.
  
• FIRST_A_APIKEY is the API key of the heroku account your primary app is in. Check it in your heroku settings, in the last of the page.
  
• FIRST_B_APPNAME is the app name of your secondary app.
  
• FIRST_B_APIKEY is the API key of the heroku account your secondary app is in. Check it in your heroku settings, in the last of the page.
  

Optional Variables
The script supports up to 3 pair of apps simultaneously. You may add these vars if you need it.
SECOND_PROCESSTYPE, SECOND_A_APPNAME, SECOND_A_APIKEY, SECOND_B_APPNAME, SECOND_B_APIKEY
THIRD_PROCESSTYPE, THIRD_A_APPNAME, THIRD_A_APIKEY, THIRD_B_APPNAME, THIRD_B_APIKEY
