+ Submit a siteThreshold41 is a web directory maintained as an expedition log — a field record of 835 active websites catalogued across 22 sectors. It is designed to help navigators find useful sites across a broad range of industries, and to give site owners a free place to log their presence on the open web.
Yes. Submission is free and open to any publicly accessible website. There are no paid tiers, featured placements, or submission fees. Fill in the submission form with your site URL and select the most appropriate sector, and the field team will review your entry.
Sites are organised into 22 sectors, each covering a distinct area of the web — from dental stations and medical outposts to wagering posts, tech depots, and transit hubs. When you submit, you select the sector that best fits your site. Sectors carry field notes describing the terrain and example entries to help you navigate.
Most submissions are reviewed and logged within a few days of receipt. The field team checks that submitted sites are publicly accessible before adding them to the record. You will not receive an automated notification, but you can search for your domain after a few days to confirm it has been logged.
Yes. Each site must be submitted individually via the submission form. There is no limit on the number of distinct sites a single owner may log, provided each one is a publicly accessible, independently operated site.
The field team conducts periodic sweeps to remove entries that are no longer accessible. If your site goes offline temporarily, it may be removed during one of these checks. You are welcome to resubmit once the site is back online and accessible.
The directory accepts submissions from sites in any language. The log itself is maintained in English, including sector names and field notes, but the listed sites operate in a wide range of languages and serve audiences worldwide.
Browse by sector using the navigation on the home page. Each sector groups similar types of sites together and includes a short field note describing the terrain. If you are looking for something specific, scanning the sector list is the fastest route to the right area of the log.
Threshold41 is an expedition log for the open web — a field record of 835 active websites catalogued across 22 sectors, from financial depots and transit hubs to fabrication yards and medical outposts. Each entry has been submitted by site owners and logged by our field team, giving navigators a reliable map of what is currently active across a broad range of industries and geographies. The directory is organised into 22 clearly marked sectors, each with field notes on the terrain and notable coordinates to help orient a first visit. Unlike editorial curations that prioritise prestige, the Threshold41 log records the landscape as it stands — varied, international, and continually updated by new submissions. Submission is free and open to any publicly accessible site. Whether you are surveying a new market, researching a sector, or looking to log your own site in the record, Threshold41 provides a straightforward chart of the active web.
