The short version

  • Only GitHub Actions has a free tier, so it costs nothing to try first.
  • 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; Split split is now a module of the Harness platform and split.io redirects to harness.io, so buying it means entering a Harness commercial relationship rather than a standalone flag vendor contract.

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

Split

  • Split is now a module of the Harness platform and split.io redirects to harness.io, so buying it means entering a Harness commercial relationship rather than a standalone flag vendor contract.
  • Harness no longer publishes per-module prices, so an organisation that wants only feature management cannot get a list price and must negotiate a module out of a platform bundle.
  • The measurement engine needs traffic volume to reach significance, so a product with modest usage gets flags with an experimentation layer it will rarely be able to conclude anything from.
  • Metric attribution depends on correctly instrumented events flowing into Split, which is an integration project in its own right; without it you have paid for an experimentation platform and are using it as a flag switch.
  • As part of a larger DevOps suite the roadmap now competes with CI, CD, security and cloud cost modules for attention, so feature management is no longer the company’s single focus the way it was as an independent product.

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.

Source
Split: Is Split still called Split?

It is now sold as Harness Feature Management and Experimentation after the Harness acquisition, and split.io redirects to harness.io.

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.

Source
Split: Can I buy just feature flags?

Not from a price list. Harness publishes bundle tiers and directs single-module buyers to sales.

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.

Source
Split: What does it do that a plain flag service does not?

It attributes changes in your product metrics to specific flags with statistical significance testing and alerts on guardrail metrics.

Split: Do we need a lot of traffic?

Yes. Statistical tests need volume to conclude, so low-traffic products get limited value from the measurement layer.
