Case Study: MATTR streamlines multi-dimensional configuration management with Doppler

MATTR cuts config errors and handles 268 change requests in a month with Doppler

Mattr, a digital identity and security company, builds whitelabel mobile apps for credential management. The technical team for their MATTR GO product faced a challenge in managing complex, multi-dimensional configurations across numerous clients and environments. Their previous method of using scattered .env files was prone to human error and difficult to scale, leading them to seek a solution from the vendor Doppler.

By implementing Doppler for non-sensitive, build-time configuration management, the team gained a centralized workflow. The solution provided config inheritance to reduce duplication, introduced Change Requests for safe production updates, and offered role-based access controls for security. As a result, Mattr streamlined its development process, significantly reducing the risk of misconfigurations. The measurable impact was clear; in a single month, the team used Doppler's Change Requests feature for nearly 300 approvals, demonstrating its deep integration into their workflow.
