Hello, I wanted to share ConfigSift, a client-side tool to compare configuration files (.env, YAML, JSON) before deployments.

You paste or drop two configs and it highlights what changed (including nested keys), with options to mask sensitive values. Everything runs locally in the browser—no uploads, no accounts.

Try it: https://configsift.com

I’d love feedback on what would make this most useful in real CI/CD workflows, and whether the UI makes diffs easy to review quickly.
