What is a URL opener?

A URL opener takes a list of web addresses and opens each one in a separate browser tab. URL opener, bulk URL opener, and multiple URL opener describe the same basic task: opening several links without copying and pasting them one by one.

This tool opens URLs in their original order. It adds HTTPS when a protocol is missing and skips entries that are not valid HTTP or HTTPS addresses.

How to open multiple URLs

Paste URLs into the input area, open a .txt file, or select Example.
Choose the delay between tabs. Use 0 ms for no intentional pause.
Select the open button, or press Cmd + Enter on macOS and Ctrl + Enter on Windows or Linux.
If your browser stops the sequence, allow pop-ups for Bitty Coder and retry the remaining URLs.

URL opener example

Enter one URL per line:

example.com
https://developer.mozilla.org/en-US/docs/Web/API/Window/open
https://www.w3.org/TR/html/
not a valid URL

The first entry opens as https://example.com/. The final line is invalid and does not create a tab.

You can also paste a column copied from Excel or Google Sheets. New lines and Tabs are recognized, along with commas and semicolons that separate URL entries.

Why add a delay between URLs?

A delay spaces out new tabs instead of creating them in the same instant. Available delays range from 0 to 1000 milliseconds.

A longer delay does not guarantee that every tab will open. Browsers may still block delayed tabs until pop-ups are allowed for Bitty Coder.

Common uses

Open competitor or backlink pages from an SEO report.
Open research sources or documentation links.
Visit several routes or test pages during QA.

Why are my URLs not opening?

Browsers limit pages that create several tabs. Allow pop-ups for Bitty Coder, then retry. The opener resumes from the first URL it could not open.

Entries using javascript:, data:, file:, or browser-internal protocols are skipped.

URL opener FAQ

Do URLs need to include `https://`?

No. A domain without a protocol receives https:// automatically. An existing http:// or https:// protocol is preserved.

What does the delay setting do?

It waits the selected number of milliseconds after opening one URL before attempting the next URL.

Why did only the first URL open?

Your browser probably blocked later pop-ups after the delay. Allow pop-ups for Bitty Coder, then retry the remaining URLs.

Can I paste URLs from Excel or Google Sheets?

Yes. Copy a column or range and paste it into the input area. New lines and Tabs are recognized as separators.

Can I open a duplicate URL twice?

Yes. Each valid input entry is opened in order, including repeated URLs.

Does a URL opener work on mobile?

It may work, but mobile browsers usually impose stricter limits on opening multiple tabs. A desktop browser is more reliable.
