The debate about whether to use a self-hosted or managed secrets management solution revolves around finding the right fit for a team's needs, considering factors such as security, time efficiency, reliability, satisfaction, and cost. While self-hosted solutions like .env files can be simple and effective for small teams with minimal sensitive information, they often struggle with scalability and require manual updates, which can lead to inefficiencies and risks. In contrast, professional managed secrets management solutions like Doppler offer a range of benefits, including automatic sharing and updating, security features such as encryption and audit logs, and integration with popular development tools and platforms, making them suitable for teams that need to operate at any scale.
