Masked Env

A list of environment variables with hidden values: a row opens by its own toggle or by the master one in the header, and all of it without client JS.

React + Tailwind, shadcn-compatible: press “Copy for AI” and your Cursor or Claude Code agent installs it with the shadcn CLI.

What you can change

  • the list of variables through variables
  • the file name through file
  • showing every value at once through revealAll

A link for your AI agent: preview, code and instructions.

FAQ

How do I add Masked Env with Cursor or Claude Code?
Press “Copy for AI” on this page and paste it into your agent's chat. The instruction contains the shadcn CLI install command, the dependencies and what to keep, so the agent installs this exact component instead of recreating a lookalike.
What does Masked Env depend on?
No npm packages beyond React and Tailwind CSS.
What can I change in Masked Env?
Adapt: the list of variables through variables; the file name through file; showing every value at once through revealAll. Keep as installed: the local --vibeui-codeblock-022-* palette — do not swap it for your theme tokens; deriving the scope badge from the key name: a hand-set badge eventually lies; the two independent sources of reveal: the master toggle and the per-row toggle.
Is Masked Env free?
Yes. The preview is open without an account; with a free account you can copy up to 20 components a month.

For developers

npx shadcn@latest add https://vibeui.club/r/pro/codeblock-022.json

This command needs a signed link: sign in and open “Component source” below — it issues a working link valid for 30 minutes. All install options

Technical notes

The component is self-contained: one file, zero dependencies, its own palette in the local --vibeui-codeblock-022-* variables. Server component: the state is held by native checkboxes, and revealing a value is switched on by two independent :has() selectors — on the row and on the whole block from the shared toggle in the header. A variable's scope is derived from its name: keys with the NEXT_PUBLIC_ prefix get a different badge, so the caption cannot diverge from reality. The checkboxes are hidden with clip-path, and each has a visually hidden caption with the key name for a screen reader.
