The short version

  • Only Cypress has a free tier, so it costs nothing to try first.
  • Each has a real cost: Cypress limited to web applications; mobile and desktop app testing not supported; 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.
  • Prices and features above were last checked on 31 August 2026.

  • Continuous integration pipelines with parallelised test executionnot Split
  • Visual regression testing and accessibility verificationnot Split
  • Flaky test detection and eliminationnot Split
  • Team collaboration on test maintenance and debuggingnot Split

Split

  • A product organisation that wants every release measured against conversion and latency by default, not only deliberate experimentsnot Cypress
  • Running A/B tests with real statistical significance rather than comparing two dashboard linesnot Cypress
  • Catching a regression at five per cent rollout because a guardrail metric fires before the change reaches everyonenot Cypress
  • A team already committed to Harness for CI and CD that wants flags in the same platform and contractnot Cypress

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Cypress

  • Limited to web applications; mobile and desktop app testing not supported
  • Free tier capped at 500 test results/month; insufficient for most development teams
  • Paid features (flake detection, analytics) not included in free tier
  • JavaScript/TypeScript focused; less suitable for polyglot organisations

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

Cypress: Is Cypress free?

Yes, Cypress offers a free Starter plan with 500 test results per month, 100 prompt executions monthly, 50 users, and 30-day data retention. No credit card is required.

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.

Cypress: How much does Cypress Team cost?

Cypress Team costs $67 per month when billed monthly or $799 per year for annual billing (11% savings). It includes 120,000 annual test results, 9,000 yearly prompt executions, 50 users, 90-day data retention, flake detection, Jira integration, and email support.

Source
Split: Can I buy just feature flags?

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

Cypress: What is the difference between Cypress Team and Business?

Cypress Business costs $267 per month (or $3,199 annually) compared to Team's $67/month ($799/year). Business provides twice the prompt executions (24,000 vs. 9,000 yearly), spec prioritization, auto-cancellation, and enterprise GitHub/GitLab support.

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.

Cypress: Can I purchase additional test results on Cypress?

Yes, Cypress allows purchasing bundled on-demand test results. Team costs $6 per 1,000 results, Business costs $5 per 1,000, and Enterprise pricing is custom. Open-source projects qualify for complimentary cloud services.

Source
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.
