A few months ago, we quit our jobs and started full time on Phase. So…

Last month, we open-sourced Infisical (https://github.com/Infisical/infisical) - a simple, end-to-end encrypted tool to sync environment variables across your team and infrastructure. You can use it to store environment variables and inject them into your applications locally or into CI/CD and production infrastructure. It can be used with any language/framework and is platform independent with a super easy setup. We know secret managers exist but, in our experience, they’re too complicated, not comprehensive, not user-friendly, or a mix of all three — other…

Finally open sourced an internal tool we've been using for managing secrets. It's similar to SOPS, but more opinionated, easier to configure/use correctly, and produces nicer git diffs. It also supports one-way encryption, so you don't have to know the private key to add secrets.
