They make it extremely easy to manage secrets across all of the environments I run code in, including on my deployed servers and CI environments.

Doppler has been the most profitable purchase of the last 2 years in the company where I work. We've been using it for 2 years now, and it enables our development and infrastructure teams to manage a whole range of secrets and configurations across our platform, synchronizing them automatically and monitoring changes. For me, it's the must-have platform for secrets management. I can't see myself going back. It's easy to use, and the options offered, such as synchronization, automatic secret rotation, project-based rights management, etc., are really game-changing.

Doppler is easy to use, with a very good UI, helpful features and an amazing support. Branch configuration is perfect to configure secrets for every review app.
