HTML5 serves as a #1 buzzword for a long time now and plays well for marketing a new generation apps. Despite being not fully supported by most of the browsers and having small backward compatibility support, it is highly demanded and well sold. The battle for mobile users plays as a great incentive for company stakeholders that spend significant budgets. They do it with the hope to get fast ROI and calm down the angry mob of mobile users that demand a Flash application they used to running on a smartphone.
Fortunately, HTML5 has shown its drawbacks immediately after first admirations subsided. HTML5 proved to be an expensive development for enterprise-level applications (like Facebook, who switched to native app development), although the internet is full of simple yet glamorous mashups and small utility apps.
When we first started development of HTML5 online product designer application, the QA and tests part of development started to take much more time than it was anticipated. Numerous browsers, platforms, mobile devices, at least 90% of them had to checked against each of LiveArt HTML5 feature. Aside of the touch functionality to work on tablet and smartphone devices, our developers had to continuously verify the look and feel to appear consistently across different resolutions. All of the above took much more resources than required for similar Flash application development.
No doubts, the obvious conclusion everyone will be able to make is that HTML5 development is much more expensive. Add responsive layout here and you will get at least twice as big budget for HTML5 than you would for Flash.
We are not advocating Flash here. As we all know, HTML5 is good because it works on mobile. You want to stay in business, you do the HTML5. It’s expensive, it’s painful in development, but in the end it will pay off in increased audience, become your love mark and keep you in the market.
