Troubleshooting
Stop second-guessing which environment you're on. EnvHub adds visual markers to your browser so you never accidentally modify production again.
Two browser tabs open. Both look identical. You make a quick edit, hit save, and realize in horror — that was production.
"Which tab is staging again?"
"Green = safe, Red = careful"
