HostDir is an independent reference and editorial publication for people who build, manage, and rely on web infrastructure. Its coverage brings together a daily news desk, practical guides, reference data, and tools in one free-to-read resource, with no paywall or signup required. Human editors write its news articles, guides are checked against relevant RFCs, and sponsored placements are labelled.

The site’s directory lists thousands of hosting providers across more than 170 markets, with ways to browse by service type or country and compare plans, including price, memory, and storage. Coverage spans shared, VPS, cloud, WordPress, dedicated, and free hosting, alongside domain registration and related services. HostDir also provides information on data centers, networks and autonomous systems, internet exchanges, backbones, CDN locations, cloud regions, submarine cables, domain extensions, registrars, public DNS resolvers, certificate authorities, and email blocklists. Additional resources include an infrastructure map, an internet shutdowns log, a glossary, an RFC index, software toolkit, RSS feed, and narrated articles.
