SAN FRANCISCO, Nov. 17, 2016 /PRNewswire/ -- Built.io ®, a pioneer in headless content management system (CMS) technology, today unveils substantial feature enhancements in a major architectural upgrade to its API-first CMS, Built.io ® Contentstack™. Reporting strong growth - particularly across Europe - the company has seen record adoption and marquee customer wins, including telecommunications Europe's leading online digital photo service PhotoBox and Swiss logistics service provider Competec. Built.io Contentstack's new features include a complete refactoring and optimization of the underlying database, resulting in major performance improvements to the core content management engine. In addition, the headless CMS now offers turnkey integration with a Content Delivery Network (CDN). By partnering with Fastly - a leading, real-time CDN provider - Built.io Contentstack can guarantee high performance access to content anywhere in the world. The CDN is directly integrated with Built.io Contentstack's Content API, which extends the performance benefits not just to websites, but also to mobile and IoT apps. In addition to lightning fast content, the new CDN provides reliability and resilience due to its ability to load-balance and dynamically poll the most responsive server. The CDN is enabled by default and requires no setup or maintenance by customers. In response to European customers' requests, the latest release adds new language-based permissions and the ability to set any language as the master language, making Built.io Contentstack particularly well suited for international companies, non-English-speaking users and multi-lingual content. "We operate an international business serving customers across many regions, so having a CMS that makes it easy to navigate multiple locales and languages is critical for our success," said Taher Khaliq, Director of eCommerce Platforms at PhotoBox. "Built.io Contentstack's new mutli-lingual enhancements and versatile API align with our need to deliver content optimized for a geographically distributed and diverse customer base." With two-factor authentication and the ability for developers to add authentication to Webhooks, Built.io Contentstack also adds two highly anticipated security enhancements in its update.
