Load time: The Heap client-side script is hosted on Cloudfront's global CDN, which allows for extremely fast load times. The size of the script is minimal (less than 6kb).
Cross-browser testing: The Heap client-side script is tested against all modern browsers, including Firefox 3+, Safari 5+, Internet Explorer 6+, all versions of Chrome, Opera 11+, mobile Safari, mobile Chrome, and several others.
Network impact: The Heap client-side script batches all events and submits a request to our servers every 2 seconds. This induces minimal network overhead, even for heavy usage applications.
Performance: Heap adds minimal CPU overhead (less than 0.1%), leaving application responsiveness virtually untouched. Our cross-browser testing suite ensures that Heap remains performant across all browsers.
Cross-platform testing: The Heap iOS library is tested on all major iOS versions 6.0 and above, as well as on all iPhone/iPad and 32-bit/64-bit device combinations.
Network impact: The Heap iOS library batches all events and submits a request to our servers every 15 seconds. This interval can be adjusted. If no network connection is present, events are cached locally.
Performance: Heap adds virtually zero performance overhead. Because all processing is done off the main thread, user interactivity and UI rendering will remain unaffected. Heap's background queue typically consumes less than 0.5% CPU.
Heap automates the annoying parts of user analytics. No more manual anything. Just insights.
