About Us

Built for people who live in tabs

Mass URL Opener is a fast, private, client-side utility for opening large lists of links without the busywork. No accounts, no installs, no server-side processing.

Our Mission

Anyone who works with links at scale knows the friction: copy a URL, paste it, click, repeat — a hundred times. We built Mass URL Opener to remove that friction. Paste a list once, clean it in seconds, control the pace, and launch every valid link in tabs or windows. The goal is simple: turn a tedious manual task into a single action while keeping your data entirely on your own device.

Why We Built It

Most bulk link tools either require an install, ask for broad extension permissions, or send your URL list to a remote server for processing. We wanted something lighter and more trustworthy: a plain web page that works in any modern browser, needs no account, and never sends your links anywhere. That is the principle behind every feature — from deduplication and UTM stripping to delay controls and local saved lists.

Who It Is For

  • SEO professionals reviewing crawl exports, redirects, and indexed pages.
  • Developers testing staging routes, environments, and documentation links.
  • Marketers verifying campaign destinations and cleaning tracking parameters.
  • Researchers and analysts opening folders of sources in one pass.
  • Everyday users launching saved reading lists, dashboards, and daily bookmarks.

What Makes It Different

  • 100% client-side: parsing, cleaning, and opening all happen in your browser.
  • No installation: works as an online alternative to bulk URL opener extensions.
  • Crash-resistant pacing: customizable delays and batch mode for very large lists.
  • Smart cleaning: duplicate removal, URL extraction from text, and tracking-parameter stripping.
  • Free to use: no sign-up, no paywall, no account required.

Our Commitment to Privacy

We do not want your browsing data, and we do not collect it. There are no server logs of your URL lists, no tracking pixels, and no data retention. Saved lists stay in your browser's local storage and can be cleared by you at any time. Read the full details in our Privacy Policy.
