The short version
- Each has a real cost: GitHub Actions private repository usage is capped at 2,000 minutes per month on GitHub Free and 3,000 on Pro and Team, with anything beyond billed; Selenium flaky tests are the standing complaint: explicit waits and synchronisation are the tester’s job, where newer tools handle it automatically

Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
GitHub Actions
- Private repository usage is capped at 2,000 minutes per month on GitHub Free and 3,000 on Pro and Team, with anything beyond billed
- Artifact storage is only 500 MB on GitHub Free and 2 GB on Team, and it is shared with GitHub Packages storage
- Larger runners are always charged for, even on public repositories and even when plan quota remains
- Windows runners cost $0.010 per minute against $0.006 for a 2-core Linux runner, so the same workflow costs more per platform
- macOS runners are charged at a higher per-minute rate than Linux runners
- Failed runs consume minutes, so a job that fails after 5 minutes and is re-run for 10 uses 15 minutes of quota
- Storage is billed on hourly accrual in GB-Hours, so deleting artifacts stops future charges but does not remove charges already accrued in the cycle
- Cache storage is a separate 10 GB per repository allowance and peak hourly usage above it is charged
- Minutes are charged to the repository owner, not the person who triggered the run, and anyone with write access can trigger runs
- Without a valid payment method on file, workflows are blocked as soon as the quota is exhausted
Selenium
- Flaky tests are the standing complaint: explicit waits and synchronisation are the tester’s job, where newer tools handle it automatically
- Setup involves drivers, versions and grid infrastructure that Playwright and Cypress bundle away
- Slower to run than tools that talk to browsers over a debugging protocol rather than WebDriver

Answered from the vendors’ own pages
GitHub Actions: How much does GitHub Actions cost?
GitHub Actions is free for public repositories. For private repositories, the Team plan costs $4 per user per month (first 12 months) with 3,000 CI/CD minutes, and the Enterprise plan costs $21 per user per month (first 12 months) with 50,000 CI/CD minutes.
SourceSelenium: Is Selenium free?
Yes, open source with no licence fee. Paid costs come from grid infrastructure or services like BrowserStack.
GitHub Actions: Is there a free version of GitHub Actions?
Yes, GitHub Actions is free for all public repositories. The Free plan for private repositories includes 2,000 CI/CD minutes per month. All tiers include free CI/CD minutes for public repository workflows.
SourceSelenium: Selenium or Playwright?
Playwright handles waiting automatically and is faster to set up, which removes most flakiness complaints. Selenium wins on language breadth, browser coverage including Safari, and existing suites you already have.
GitHub Actions: What does the Team plan add to GitHub Actions?
The Team plan provides 3,000 CI/CD minutes per month compared to 2,000 on the Free plan. It costs $4 per user per month for the first 12 months. Minutes apply only to private repository workflows.
SourceSelenium: Is Selenium still relevant?
Yes. Its WebDriver protocol is a W3C standard implemented by every major browser, and very large existing suites are not rewritten cheaply.
