Will my Heroku app working on 1 web dyno stay active if I pay for 1 worker dyno?

Tags:

heroku

I currently have an app deployed on Heroku which runs on two web dynos so it won't go to sleep if it remains inactive for a certain time.

Now if I scale it down to only one web dyno (free) and instead pay for one worker dyno, will Heroku always keep my app active?

How long does a Heroku dyno last?

Personal accounts are given a base of 550 free dyno hours each month. An additional 450 free dyno hours is available for all accounts verified with a credit card for a total of 1000 hours per month.

How long does Heroku app stay up?

If an app has a free web dyno, and that dyno receives no web traffic in a 30-minute period, it will sleep. In addition to the web dyno sleeping, the worker dyno (if present) will also sleep.

How do I keep my Heroku app awake for free?

NewRelic Availability Monitoring If you install the NewRelic Heroku Addon you can set up availability monitoring. You provide a URL which NewRelic pings every 30 seconds, therefore keeping your app awake.

It will still idle - you NEED to have more than a single web dyno
