Bulk URL Opener
Launch hundreds of links in separate tabs with one click. Safe, efficient, and 100% private.
Crucial: Allow Pop-ups
To protect you, browsers block multi-tab opening by default. When you click Launch Tabs, look for the 'Pop-up blocked' icon in your address bar and select 'Always allow pop-ups from filecast.online' to enable this tool.
Bulk URL Opener & Mass Link Manager
Opening a dozen web pages one by one from a spreadsheet is tedious. The FileCast Bulk URL Opener allows you to paste hundreds of links and safely open them into separate browser tabs automatically with perfectly spaced execution intervals.
Unlike sketchy browser extensions that demand sweeping permissions across all your web activity, our HTML utility utilizes local logic. By letting you set custom millisecond delays, we ensure your browser doesn't crash from memory overload, making it essential for Quality Assurance and SEO link audits.
