Folio39 began as a straightforward proposition: keep a careful record of operating web presences, organised into sections, available for anyone to browse. The result is a field-notebook directory — methodical, open, and free of commercial ranking.
The catalogue currently holds 828 entries across 22 sections, spanning everything from dental practices and law firms to gaming platforms and travel operators. Each entry represents a domain submitted directly by its owner and reviewed before it was added to the record.
Unlike aggregated data products that surface information without direct submission, Folio39 relies on operators to step forward and log their own presence. This keeps the record fresh and relevant, and it means that every entry is associated with a site that has actively chosen to participate.
Browsing the directory is free and requires no account. The 22 sections are the primary navigation tool — each one covers a distinct area of web activity, from the broad (Networks & Portals, with 189 entries) to the focused (Parcels & Premises, currently holding 5). Finding the right section is usually enough to surface what you are looking for.
If your site is not yet in the catalogue, the addition form is the starting point. Submissions are reviewed on a rolling basis and approved when they meet the directory guidelines. There is no fee and no registration required.
