UTM Link Builder

Builds links with UTM parameters (source, medium, campaign, term, content) from a base URL, with URL validation, correct encoding, detection of UTM parameters that already exist or are duplicated, presets for each platform (newsletter, Facebook, Instagram, TikTok, LinkedIn, YouTube, paid campaign), and CSV export. The link is never sent to any server.
