Can React Native apps be tested in a browser? : <p>Realizing that React Native apps are designed to be developed / tested using simulators, is it possible to use a web browser to also test an application?</p>

<p>Services such as <a href="https://rnplay.org/" rel="noreferrer">https://rnplay.org/</a> exist, however my concern is it's powered by <a href="https://appetize.io/" rel="noreferrer">https://appetize.io/</a> it might be limited by the # of minutes per month.  I'd also like to utilize free / open-source technology to accomplish this, as compared to a paid screen streaming service.</p>

<p>Along these lines, in order to test the app in a browser, would the app be required to use one or more libraries which allow the app to be run in both React Native and also simply React?  I'd like to find an alternative to this particular approach as I'd like to code for React Native specifically.</p>
