The analytics data provided by the M* team is used as the basis for analysis. Additionally, the browser support of other commonly used design systems was researched. The analysis revealed the following general findings, which we take into account for the operation of MDX:
- Mobile devices account for the majority of access, followed by desktop usage.
- Safari Mobile typically has the largest share.
- The most commonly used browsers for the majority of access are Safari, Chrome, Samsung Internet, Edge, and Firefox.

Based on the browser matrix defined above, a browserslist is created, which is used in the package.json within the Git repository.
Technical Requirements
MDX relies on modern web technologies; older browsers are therefore only supported to a limited extent.
Review & Update
The MDX browser matrix is reviewed at least once per year. New browsers or significant market changes may influence the update cycle and support levels.
Reductions or extensions are documented and communicated transparently.
