If you're planning to use Render's free plans as an alternative to Heroku, then you should know about this: "Render’s free database plan allows you to run a PostgreSQL database that automatically expires 90 days after creation. Free databases are suspended after 90 days (unless they are upgraded to a paid plan), and are no longer reachable at this point." so as a workaround, you should keep creating free databases after every 90 days.
