GitHub now gives two things for Actions costs: the detailed usage report (a CSV with cost per repo and workflow) and the Actions usage metrics page under Insights.

If you use them: is there a cost question they still don't answer for you? For example why the cost went up this week, which team caused it, or what to fix first.

If you don't use them: what do you use instead? A script on the billing API, Grafana, a spreadsheet, or nothing?

About me: I'm a solo developer building a small tool in this area. I want to know where GitHub's own tools are already enough. No link.

The current billing page shows:

• Total minutes used (org-level)
• Breakdown by OS (Linux/Windows/macOS)
• That's it.

What I actually need:

• Which of my 30 repos is consuming the most minutes?
• Which specific workflow is the most expensive?
• Which team member is triggering the most costly runs?
• Is my bill trending up or down week over week?

I end up pulling data from the API manually every month to build a spreadsheet for my manager. Am I the only one who finds the native billing insufficient? Would you pay for a tool that did this automatically?

Just discovered one of our devs set up a lint workflow using macos-latest instead of ubuntu-latest. That's $0.08/min vs $0.008/min — 10x more expensive. It was running 400+ times a month. $300 down the drain for months before anyone noticed.

GitHub's billing page doesn't break down costs per workflow, so there was no way to spot this without manually digging through the API.

What's your worst accidental Actions cost waste? And how do you prevent this kind of thing from happening?

We have ~40 repos with github actions and our monthly bill keeps climbing. The billing page only shows org level totals by OS type, but I can't figure out which specific workflow or repo is the biggest cost driver without manually calling the API for every single run.

How are you all handling this? Do you:

1. Just accept the bill and move on?

2. Built some internal script to calculate per-workflow costs?

3. Use a third-party tool? (I haven't found one that does this well)

4. Manually audit workflow files once in a while?

Our bill went from $800 to $1400 /month in 3 months and I can't explain why to my manager. Would love to hear how others deal with this.
