The short version

  • Only Playwright has a free tier, so it costs nothing to try first.
  • Each has a real cost: Playwright requires programming language knowledge; not suitable for non-technical QA staff; 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.

Split

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

Where each one falls short

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

Playwright

  • Requires programming language knowledge; not suitable for non-technical QA staff
  • WebKit implementation less mature than Chromium; occasional webkit-specific issues
  • Mobile browser testing relies on emulation, not real devices
  • No managed cloud infrastructure; users must host CI/CD runners or pay for third-party services

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.

Split: Can I buy just feature flags?

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

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.
