YapCRM uses a combination of what is cost effective and what is time effective.
We have seen the issues of reliance on open source solutions, frequently a hack on one site can open the door on tens of thousands of other sites.
As such we try strike a balance between cost, easy of use and security.
We use Adobe Coldfusion despite the high inital cost, it is an enterprise level rapid development solution, the original MySpace was made in less than 2 weeks using Coldfusion.
The excellent integration with PDF and Office products and fast development time mean we can develop new solutions rapidly and offer better value to our clients.
MySQL has become the world's most popular open source database solution because of its high performance, high reliability and ease of use.
MySQL was good enough for Facebook, thats good enough for us.
We have dedicated servers in London & Seattle to provide global coverage for our clients.
We support four browsers, although we are confident YapCRM will work on any web standard browser.
For ease of design, we only validate CRM coding with Firefox, Chrome, Safari and Internet Explorer/Edge.
Who do we recommend? Firefox.
