Regex Editor & Tester

Matches the start of a URL by finding the 'http://' or 'https://' scheme, followed by any number of extra forward or backslashes, and optionally the 'www.' subdomain prefix. This makes it tolerant of malformed or over-escaped links like 'https:///example.com' or 'http:\\www.site.com'. Useful for link detection, extraction, and auto-linkifying text, with global and multiline flags to find matches across every line of input.
