EnvMate

EnvMate is a browser extension that helps development, QA, and product teams work with multiple environments more clearly and efficiently. It identifies development, test, staging, and production environments based on URL rules. On matched pages, EnvMate can display environment badges, watermarks, page title prefixes, or a breathing edge glow. It also lets you customize the browser tab’s favicon, title prefix, and title, helping you quickly confirm which environment you are using. You can organize environments by product or business line, check the current environment, quickly open frequently used environment homepages, and configure multiple test accounts for different environments. Configuration data can be imported or exported as JSON files, or loaded from a URL with selectable groups and environments. When reviewing page copy or preparing screenshots, you can also edit page text directly. Whether you are developing features, testing integrations, validating releases, preparing deployments, or giving product demos, EnvMate helps you distinguish environments at a glance and reach the right system quickly. It reduces mistakes and wasted time caused by similar-looking pages, environment confusion, and frequent switching between systems. 2026-09-13 · v0.6.0: Added tab configuration for customizing the browser tab favicon, title prefix, and title.
