I built env-rx out of pure frustration with a painfully common problem. Someone on the team adds a new environment variable locally, forgets to share it or add it to the CI secrets, and the pipeline crashes right during deployment.

What makes it different: There are plenty of great secrets managers out there (like Doppler, Infisical, or Vault), but they often require team-wide buy-in, cloud syncing, and complex setups. I didn't want a heavy SaaS tool. I just wanted a lightweight, fast CLI utility that you can drop into any project, and it will loudly catch missing variables before you push or deploy.

It's designed to be zero-config. I’m releasing this open-source version first because I want to gather harsh, honest feedback from developers. I'd love to hear your thoughts on the DX or any edge cases I might have missed. If you manage to break it, please let me know!
