The short version
- Each has a real cost: Detox it only benefits React Native apps; teams with native iOS, native Android, or non-React-Native hybrid apps get no advantage from its core gray-box synchronisation design and should use Appium instead.; Selenium flaky tests are the standing complaint: explicit waits and synchronisation are the tester’s job, where newer tools handle it automatically
- They diverge on capability: Detox covers Gray-box synchronisation, Selenium covers W3C WebDriver.

Where they differ
Only the attributes on which Detox and Selenium actually diverge.
Identical on both: starting price (Free), pricing model (Open source, no licence fee), free tier (Yes), user rating (Not yet rated), category (Testing).

What people use each for
The jobs each tool is most often brought in to do.
Detox
- A React Native team wanting end-to-end tests that reliably wait for real app state rather than fixed sleep delaysnot Selenium
- A CI pipeline running mobile end-to-end tests that need to be genuinely reliable, not flaky, to avoid blocking merges on false failuresnot Selenium
- A team migrating from Appium-based React Native testing wanting tighter synchronisation with the app's async internalsnot Selenium
- An engineering organisation wanting a free, actively used-in-production framework rather than a lightly maintained side projectnot Selenium
Selenium
- Cross-browser testing where Safari and legacy browsers must be coverednot Detox
- Teams whose test suites are written in Java or C# rather than JavaScriptnot Detox
- Distributing a large suite across a grid of machinesnot Detox
Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
Detox
- It only benefits React Native apps; teams with native iOS, native Android, or non-React-Native hybrid apps get no advantage from its core gray-box synchronisation design and should use Appium instead.
- As a single-company open source project, its long-term maintenance priority is tied to Wix's own continued internal use of React Native and Detox, which is a real, if currently low, dependency risk.
- Initial setup, particularly around build configuration for iOS and Android, has a steeper learning curve than some competing frameworks, with configuration errors being a common source of early frustration.
- Its community and plugin ecosystem is smaller than Appium's broader, foundation-governed mobile automation ecosystem.
- Debugging synchronisation issues when the gray-box mechanism misjudges app idle state can itself be a non-trivial troubleshooting exercise, ironically producing the same kind of flaky-test debugging it is designed to avoid.
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

Questions people ask
- Is Detox or Selenium better?
- Neither clearly leads. Detox starts at Free and Selenium at Free, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.
- Which is cheaper, Detox or Selenium?
- Detox starts at Free and Selenium at Free.
- Does Detox or Selenium run on more platforms?
- Detox runs on iOS, Android. Selenium runs on Linux, macOS, Windows, Web.
- Can I use Detox for free?
- Both have a free tier, so you can try either at no cost before committing.
- What is Detox best used for?
- Detox is most often used for a react native team wanting end-to-end tests that reliably wait for real app state rather than fixed sleep delays, a ci pipeline running mobile end-to-end tests that need to be genuinely reliable, not flaky, to avoid blocking merges on false failures, a team migrating from appium-based react native testing wanting tighter synchronisation with the app's async internals, an engineering organisation wanting a free, actively used-in-production framework rather than a lightly maintained side project. Of those, a react native team wanting end-to-end tests that reliably wait for real app state rather than fixed sleep delays and a ci pipeline running mobile end-to-end tests that need to be genuinely reliable, not flaky, to avoid blocking merges on false failures are not what Selenium is typically brought in for.
- What can Detox do that Selenium cannot?
- Detox covers Gray-box synchronisation, React Native native integration, Real device and simulator support, Jest integration. Selenium covers W3C WebDriver, Many language bindings, Selenium Grid, Broad browser support.
Answered from the vendors’ own pages
Detox: Is Detox owned by Wix?
Yes, it is built and maintained by Wix as an open source project, used internally across Wix's own React Native apps.
Selenium: Is Selenium free?
Yes, open source with no licence fee. Paid costs come from grid infrastructure or services like BrowserStack.
Detox: Does Detox work with native iOS or Android apps, not just React Native?
It is specifically designed around React Native's architecture; for native or non-React-Native hybrid apps, Appium is the more appropriate choice.
Selenium: 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.
Detox: Is Detox free?
Yes, entirely open source with no licence fee.
Selenium: 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.
