Optimization savings

Three levers that cut Playwright CI spend. Projected monthly savings on each.

Shard the suite across more runners

-$67.20

With fewer than 8 parallel runners and a 6-minute plus wall time, sharding typically saves 30 to 40% of CI minutes.

Remove dead and low-value tests

-$23.04

Most suites carry 10 to 15% of tests that never fail and rarely cover new code. Removing them is pure savings.

Eliminate flaky retries

-$15.36

Retries and reruns on flakes waste roughly 5 to 10% of CI minutes across most suites.

Annual savings potential
$1,267

Savings percentages come from patterns across TestDino customer suites. Real savings vary.

How this works?

How the calculator turns your pipeline inputs into monthly cost and savings projections.

Total CI minutes

We multiply your PRs per day by working days per month to get monthly runs, then multiply by suite wall time and parallel runners to get total CI minutes consumed.

Billable cost

Included plan minutes are subtracted first. The remaining billable minutes are multiplied by your runner cost per minute to produce the monthly dollar figure.

Optimization savings

We model three levers: sharding savings (35%, when you have fewer than 8 runners and a suite longer than 6 minutes), dead-test removal (12%), and flaky-retry elimination (8%).

Annual savings potential

Applicable monthly savings are summed and multiplied by 12. The result shows what you could recover each year by acting on the optimizations your current setup leaves on the table.

FAQs

Monthly runs equals PRs per day times working days per month. Total CI minutes is monthly runs times suite wall time times parallel runners. Subtract your plan-included minutes, then multiply the remainder by your runner cost per minute.
