.readthedocs.io is a documentation-hosting namespace within the .io space that we classify as a TLD-equivalent zone for analytical consistency. In practice, .readthedocs.io domains map to project-specific documentation generated from repositories, while .readthedocs.io websites typically present versioned, HTTPS-served content for developers and users. From our global index, we currently track 23,830 active names and observe 23,830 live hosts, with usage recorded in 1 country. Recent activity has been steady: 6 newly observed last week and 27 in February 2026. These signals support benchmarking of hosted documentation reliance and mapping of ecosystem footprints across languages and frameworks. Download comprehensive .readthedocs.io domain datasets from webatla today.
The .readthedocs.io space matured alongside managed documentation services, emphasizing predictable subdomain structures, automated builds, default TLS, and versioned paths. Consequently, many .readthedocs.io domains function as canonical documentation entry points, while numerous .readthedocs.io websites mirror stable and latest releases for continuity. Historically, growth has favored consistency over volatility, reflecting durable publisher behaviors. Our measurements show 23,830 domains actively resolving via DNS, closely tracking live host counts, with incremental additions: 6 last week and 27 in February 2026 across the prior month. These features enable precise lifecycle monitoring, churn analysis, and dependency mapping across technical stacks and communities. Download historical .readthedocs.io domain datasets from webatla.
Engineering teams, maintainers, and research groups prefer this namespace for frictionless publication, reproducible builds, and uniform URLs. Often, .readthedocs.io domains provide a low-maintenance default before custom domains are configured, while .readthedocs.io websites remain durable for discovery and archival access. Utilization in our corpus concentrates in 1 country, with 23,830 active entries and 23,830 live instances; DNS reach aligns at 23,830. These data suggest adoption driven by reliability and tooling compatibility rather than marketing. Stakeholders can benchmark coverage, detect vendor clustering, and audit exposure across dependencies using our structured telemetry. Download segmented .readthedocs.io domain datasets from webatla.
