Sitemark

Stop double-checking the URL bar. Know what you're looking at, instantly. If you've ever run a destructive query, pushed a config change, or clicked "delete" on what you thought was staging — only to realize it was production — Sitemark is for you. Sitemark pins a small, unmissable badge into the corner of any page that matches a rule you define. One glance tells you exactly what you're looking at, before you touch anything. Built for real workflows: 🎯 Environment safety — color-coded PROD / STAGE / DEV / LOCAL badges across every brand and deployment you manage 🏢 Agency & client work — label which client's site you're on, at a glance ⚠️ "Not customer-facing" — flag internal tools, admin panels, or shared accounts so you never forget 🌐 One rule, whole fleet — a single wildcard pattern labels every host in an admin panel fleet by name Exactly one badge, never a guessing game. If two rules could describe a page, Sitemark's matching engine picks the more specific one — no ambiguous "which one is right?" moment. Need a persistent flag (like "shared account") alongside your environment badge? Pin it, and both show up, clearly separated. Make it yours: - Full control over color, icon, position, and text for every rule — including a dedicated color per group and per tag, so PROD and DEV read differently at a glance without extra setup - Instant search, right on the page — press Cmd/Ctrl+K (or Alt+Shift+S from anywhere, no need to open the popup first) to pull up every rule you've configured and jump straight to it; Ctrl/Cmd+click to open it in a new tab instead - Drag any badge to reposition it, or resize it — remembered per site - Live pattern tester shows exactly which rule wins and why, before you save - Import/export your config as JSON — back it up, share it with your team Built for privacy, not surveillance: - Zero network requests. Ever. - Zero data collection, zero analytics, zero tracking. - Everything lives in your browser's local storage — never leaves your machine. - Open source and readable in minutes — no bundler, no obfuscation, no third-party dependencies. Lightweight, fast, and works from the very first page load — so the badge is there before you can accidentally act on the wrong tab.
