Overview

Environment marker for dev/stg/prod - works with SPA and non-URL switches

Context Marker visually marks your browser tabs to help distinguish between environments like production, staging, and development. Features: - Flexible detection rules — match by URL pattern, DOM text, meta tags, cookie values, or custom selectors - Three display styles — top bar, corner ribbon, or bottom bar - Fully customizable — set colors, labels, opacity, and position per rule - Priority-based rule matching — first matching rule wins - Zero data collection — all configuration stays in local browser storage Perfect for developers, QA engineers, and anyone who works across multiple environments and needs a quick visual indicator of which environment they're currently viewing.
