Funny that this depends on the Heroku scheduler to work. Why not just throw a curl command in the Heroku scheduler like everyone else? I can’t think of a reason to use this when you have cron and a bash script with a curl command in it.

Or pay $7 a month to get a hobby dyno... you cant possibly need 24x7 uptime if you can’t afford $7 a month.

This isn't for 24/7 uptime. And it also doesn't depend on Heroku scheduler. That's just one option for getting this up and running quickly.

Alternative title: how to ruin free tiers for everyone

Why is this the case? This stays within Heroku's limits for free tiers. They cap free dyno hours anyways so if you need your app awake all the time you have no choice but to pay.

If everyone kept their free dynos up the maximum amount of time, that limit would probably be a lot lower.

Just add your site to any uptime monitoring tools like https://uptimerobot.com or https://webmonitoring.online

The problem with this is that you don't want your free dyno to stay awake all the time because free dyno hours are capped. This tool let's you set a window to pause the requests.

You only get a limited number of free hours. 1000 with a credit card otherwise 550.

Yep! This works around that by having a window where the requests are paused.
