The short version

  • Only Percy has a free tier, so it costs nothing to try first.
  • Each has a real cost: Percy pixel-based diffing generates more false positives from font rendering and anti-aliasing noise than Applitools' AI-based comparison, which trains some teams to start ignoring diff alerts over time.; 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.
  • They diverge on capability: Percy covers Screenshot diffing, Split covers Feature flags with targeting.
  • Prices and features above were last checked on 1 September 2026.

What people use each for

The jobs each tool is most often brought in to do.

Percy

  • A team already on BrowserStack for device testing that wants to add visual regression without a separate vendor relationshipnot Split
  • A low-traffic project that can run indefinitely on the 5,000-screenshot free tier without paying anythingnot Split
  • A team wanting a lower cost per screenshot than Applitools and willing to tolerate more manual false-positive triagenot Split
  • A Cypress or Playwright test suite adding visual checks without changing its existing test runnernot Split

Split

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

Where each one falls short

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

Percy

  • Pixel-based diffing generates more false positives from font rendering and anti-aliasing noise than Applitools' AI-based comparison, which trains some teams to start ignoring diff alerts over time.
  • It is billed separately from core BrowserStack device testing, and stacking Percy with other BrowserStack modules such as Accessibility Testing materially increases total contract value beyond the headline device testing price.
  • Paid tier pricing above the free tier is not transparently published as a fixed number, requiring a quote to know actual cost at scale.
  • The free tier's 5,000-screenshot cap is easy to exceed for any team running visual tests across multiple browsers and viewports on every commit, pushing many active projects into a paid tier faster than the free number suggests.
  • As part of a larger acquired portfolio, Percy's roadmap priority within BrowserStack's broader product strategy is less certain than it would be as a standalone company's sole focus.

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

Percy: Is Percy free?

Yes for up to 5,000 screenshots a month with unlimited users and projects; beyond that it is a paid, quote-priced module.

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.

Percy: Is Percy included if I already pay for BrowserStack device testing?

No, it is billed separately by screenshot volume, not bundled into core device testing plans.

Split: Can I buy just feature flags?

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

Percy: How does it compare to Applitools?

Percy uses pixel-based diffing, which is generally cheaper per screenshot but produces more false positives than Applitools' AI-based perceptual comparison.

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.
