Just ran the numbers. Our CI/CD bill is now 40% higher than our cloud hosting costs for the actual application.
We're on a major platform's "pay-per-minute" plan. The culprit? 250k build minutes a month, mostly spent on matrix jobs for testing against three node versions and four OS targets. Every PR triggers the full suite.
```yaml
# The config that prints money.
strategy:
matrix:
node-version: [18, 20, 22]
os: [ubuntu-latest, windows-latest, macos-latest]
```
Self-hosted runners could cut this by 60%, but then that's my problem. The irony is delicious. We're spending more to build the thing than to run it.
Prove it.
