Onboardbase was built to solve this use case. It manages and syncs your env across every stage of development.(Disclaimer: I’m the founder.)

I honestly started building this out of the need not share credentials and envs over communication channels like slack anymore. I needed a seamless and secure way to work with envs without having it scattered and fragmented across several mediums.

Envs are essential to how you work and i believe a solution shouldn't just be secure but it should also be seamless to how you work
