Save up to 75% of your costs on your Heroku staging and review apps

AutoIdle automatically puts your staging and review apps to sleep when you don't need them.

Here’s how it works


When an app is inactive for 30 minutes, AutoIdle puts it to sleep. Without you lifting a finger.


If the app receives an HTTP request, AutoIdle reactivates it. With the same dyno count and active processes present.


See your Heroku bill shrink immediately. You’re only paying for the time you’re actively using the app.

AutoIdle is one of those great little apps that you activate and then just forget about it. It literally saves you a ton of money and lets you stop wasting resources.
