See what your Heroku apps really cost each month
Every Monday, WebRun opens the Heroku dashboard, reads the dyno size and the add-ons attached to every app across your pipelines, works out what each app is costing, flags the apps still running with no traffic, emails you the full breakdown, and posts the totals to Slack.

How do I see what each of my Heroku apps and add-ons costs?
WebRun reviews your Heroku dashboard every Monday, reading the dyno size, the add-ons, and the usage on every app across your pipelines. It emails you a per-app cost breakdown through Gmail and posts the totals to Slack with idle apps flagged, so platform spend is visible before the invoice arrives.
- Platform spend is visible weekly, not when the invoice lands
- Idle apps and duplicate add-ons are named with their saving
- Every app carries its dyno size, add-ons, and monthly cost
Built for engineering leads · platform teams · startup CTOs · finance operations

How is each run configured?
Secure by default
Connect once, stays signed in
WebRun signs in once and keeps each session in a persistent environment, so every run picks up right where it left off.
Every action is checked against this policy before it runs.
Questions, answered
Will it scale down apps or remove add-ons?
No. WebRun reads your Heroku dashboard and reports what each app costs. Scaling a dyno down or removing an add-on stays with your team, so nothing production-facing changes on its own.
Where do the cost figures come from?
From the dyno types, add-on plans, and usage shown in your own Heroku account. WebRun reads what your account displays rather than estimating from published price lists.
Who receives the email?
Only you and the engineering leads you name. The breakdown is internal, and nothing is sent to a vendor or anyone outside your team.
