Herald21 is a web directory — an index of websites logged across 22 subject sections and made available for public browsing. The current count stands at 831 entries, gathered from a wide range of commercial and professional fields. The index was put together with a simple aim: to provide a clear, navigable record of websites operating in different trades and sectors. Every site filed in Herald21 has been reviewed before it was accepted, and the sections are arranged to make browsing as straightforward as possible. Categories range from health clinics and law firms to automotive workshops, gaming platforms, and travel operators. General business listings, the largest section in the index, account for a significant share of entries, reflecting how varied commercial activity on the web has become. Submissions are open to any site that meets the basic criteria for listing. The process is straightforward: choose the most appropriate section, provide the site address and a brief description, and file the submission. Approved entries are added to the public index. Herald21 is maintained as an open reference tool. No payment is required to browse, and there is no charge for standard submission. The directory is updated on a continuing basis as new entries are reviewed and approved.
