About concealer

concealer is a companion toolbar UI for the concealer secret manager — The local-only secret manager for the AI-coding era. Open your vault and copy secret values from Chrome without ever typing `cer web`. FEATURES • One-click copy — click a secret to copy its value; the clipboard auto-clears after a few seconds. • Per-field copy — multi-field secrets (database host/user/password, OAuth app key/secret/token…) expand into child rows. Copy or reveal exactly the field you need; non-secret fields show inline. • On-demand — the local vault server starts only when you open the popup and shuts itself down when idle, so nothing lingers in the background. • Auto-lock — a countdown locks the popup on its own short timer (configurable), independent of the server, and blinks when it's about to expire. • Password generator — generate strong passwords / hex / base64url / UUID and copy them. • Themes — Dark, White, and Matrix, matching the concealer web UI. • Search — filter by name, tag, project, or environment. PRIVACY The extension talks ONLY to your own concealer server on 127.0.0.1 (localhost). No data is collected, and nothing is ever sent to a remote server. Secret values are never logged. REQUIREMENTS (one-time) 1. Install concealer: brew install fxerkan/tap/concealer (macOS) or: scoop install fxerkan/concealer (Windows) 2. Register the native helper: cer chrome-extension The extension shows this setup step until it's done. Open source: https://github.com/fxerkan/concealer
