With more than 20 years’ experience creating WYSIWYG editors, CKEditor is the expert in rich text editing. Our flagship product, CKEditor 5, is trusted by both Fortune 500 companies and hundreds of millions of users worldwide, for its almost limitless possibilities and customizations.

The latest version, CKEditor 5, was rewritten in TypeScript with a modern MVC architecture, custom data model and virtual-DOM structures, and is purpose-built for collaboration. It effortlessly works with modern tech stacks and easily handles complex implementations and edge cases. Developers have complete front- and back-end control of the editor, to easily configure, customize and control every aspect of the editor’s look, feel, and functionality. Infinite possibilities are achievable with the CKEditor WYSIWYG: collaborative tools and advanced features are individually selected, to perfectly suit your application and users. 

The story began in 2003 with a single open-source side project, when Brazilian developer Frederico Caldeira Knabben built a groundbreaking rich text editor, known as FCKEditor. The software rapidly became so popular in the open-source community that the project quickly expanded. CKSource was established in 2006 and has steadily grown ever since. In 2021, the company became part of Tiugo Technologies, a PSG portfolio company specializing in global, API-first developer platforms in the document and data management markets. 

CKSource now has over 80 employees, including more than 50 talented developers. In addition to making our market-leading software, we’re dedicated to supporting our people and building a brilliant company culture. In September 2022, CKSource was awarded the Great Place to Work® Certification™ – a global ranking based entirely on employee satisfaction.
