Environment Favicon Switcher di Thomas

Stop Guessing Which Environment Is Open

Environment Favicon Switcher makes development, review, staging, sandbox, and production tabs instantly recognizable.

No more opening the wrong tab, editing production by mistake, or searching through identical favicons.

Clear Visual Indicators:

• Custom favicons
• Colored toolbar badges
• Optional title prefixes such as [DEV], [STAGING], or [PROD]
• Automatic updates during single-page application navigation

Powerful URL Matching:

Create precise rules using:

• Domains and subdomains
• URL text
• Glob patterns
• Regular expressions
• Exclusion patterns
• Explicit priorities

When several rules match, conflicts are resolved predictably. The built-in URL tester shows exactly which rule wins and why.

Built for Real Development Workflows

Use it with:

• Local development servers
• Pull request and preview deployments
• Test, sandbox, and UAT environments
• Staging applications
• Production websites
• Multi-project and multi-team setups

Organize rules into groups, duplicate configurations, reorder priorities, or temporarily disable environments without deleting them.

Use Your Own Visual Identity:

• Choose from built-in icons, generated favicons, imported images, remote HTTPS images, or the website’s original favicon.
• You can keep production branding untouched while still displaying a clear badge or title prefix.

Import, Export, and Sync:

• Export your configuration as JSON for backups or team sharing.
• Settings are stored locally by default. Optional browser synchronization lets you reuse the same configuration across profiles or devices.

Privacy First:

No analytics. No ads. No tracking. No telemetry. No developer-operated backend. No remotely hosted executable code.

Make every environment unmistakable before you click, test, edit, or deploy.
