Generate a whole list of URLs from a single template. Write your link with a placeholder — either {n} or {} — where the changing part goes, then choose how to fill it. In number-range mode you set a start, end and step, and can zero-pad the numbers to a fixed width so that 1 becomes 001; the range works upward or downward. In value-list mode you paste one value per line and each becomes a URL, which is handy for slugs, IDs or usernames. Every placeholder in the template is replaced on each line.
Perfect for building pagination links, sitemap entries, download sequences or test URLs, then copying them all at once. Everything runs locally in your browser — your text never leaves your device.
