Heroku Eco plan


End of Free plan

Starting October 26, 2022, Heroku began deleting accounts that have been inactive for over a year.

Starting November 28, 2022, Heroku stopped offering free product plans and start shutting down free dynos and data services. Free accounts are converted to Eco plan with dynos sized zero (i.e. stopped without billing).

This means that if you wish to continue using Heroku you need to upgrade your plan.

Too complicated? Not what you're looking for? Consider a hosted Nightscout service! Check for easier solutions here.

Prevent your Nightscout app from falling asleep

Use with caution

If an app fails and crashes at startup (database full), if you entered wrong credentials and the app stops for missing data activity, using this trick to keep it alive will not help. It might even make things worse in the case of wrong Dexcom credentials and lead to a locked account.

This is necessary if you don't have an uploader sending data to Nightscout, or a follower polling data from it.
For example using the bridge plugin.
