Simplex is a lightweight, web-based toolkit from SNOMED International that enables Members and Affiliates to create and manage SNOMED CT extensions quickly, easily, and at no cost.
It is designed for organizations that need a practical and affordable way to tailor SNOMED CT content, such as:

By providing a self-service, online solution, Simplex lowers both technical and financial barriers to extension management, while ensuring your extensions remain standards-compliant and ready for distribution.
Simplex is especially suited to:
Organizations with basic extension needs,
Users who don’t have access to other extension management platforms,
Teams looking for a cost-effective and automated environment for extension release.
