Heroku/Render

Deploy 2 apps
app #1 sends request to app #2 every minute
app #2 sends request to app #1 every minute
they never sleep
profit?

Explain?

Now you just need to figure out how blockchain and AI factor in, and you can do a seed round!

This doesn't really work tho i mean you will exhaust your app's requests coz heroku limits requests for free hosted apps so your app wont last a month at this rate

if you have a db and uploading media and files to your app

you need to link to external db cloud service

this is a solution i came across some 2 years ago

you may need to research on it

Use a worker dyno if you dont need incoming requests and if you do and want to be up all the time, use kaffeine.herokuapp.com
