Troubleshooting
Stop second-guessing which environment you're on. EnvHub adds visual markers to your browser so you never accidentally modify production again.
Two tabs open, pixel-for-pixel identical. You run the command, and the sinking feeling arrives half a second after the enter key: that was production.
"Which tab is staging again?"
"Green = safe, Red = careful"
Choose the display style that works best for your workflow
Full-width bar at any edge of the page
Border around the entire viewport
Corner ribbon for minimal intrusion
Floating badge that stays out of your way
