Env Manager
This handles environment variable validation across Next.js, Vite, React, Node.js, and Flask projects with a focus on catching the stuff that breaks deployments. It checks for missing vars, detects secrets accidentally exposed in client-side prefixes like NEXT_PUBLIC_ or VITE_, and validates framework-specific conventions. The compare mode is genuinely useful for onboarding since it diffs your .env against .env.example to catch gaps. It's pure Python with no dependencies and runs fast enough for CI pipelines. Honestly most valuable for teams that have been bitten by the "works locally, fails in prod" problem or have leaked API keys in client bundles before.
