What is Read the Docs?
Read the Docs is a documentation hosting and continuous documentation delivery platform (developer tooling / documentation infrastructure) that automates building, versioning, and publishing technical documentation directly from source repositories.
- Hosts and serves versioned technical documentation with automatic builds from source control (documentation hosting).
- Integrates with Git-based workflows to trigger documentation builds on commits, tags, and branches (CI/CD for docs).
- Supports Sphinx and other documentation toolchains for configurable builds and themes (documentation tooling).
- Provides search, navigation, and localization features for published documentation sites (developer documentation portals).
- Offers a commercial Software-as-a-Service (SaaS) service with private projects, Service Level Agreements (SLAs), and compliance features for organizations (enterprise documentation platform).

More About Read the Docs
Read the Docs is a documentation platform (developer tooling / documentation infrastructure) that automates building, versioning, and hosting software documentation directly from source code repositories. It targets development teams that maintain their documentation as code, typically alongside application or library sources. The core model is that users connect a project repository, configure a build process, and allow the platform to generate and publish HTML documentation whenever changes are pushed.
The service focuses on documentation-as-code workflows (DevOps tooling), integrating with Git hosting providers to track branches, tags, and pull requests. On each configured trigger, Read the Docs runs a documentation build using tools such as Sphinx and related Python-based ecosystems (documentation toolchains). The platform handles dependency installation, configuration via files like conf.py and YAML-based build configuration, and output generation. Build logs and status information are available through the project dashboard for troubleshooting and audit.
For consumption, Read the Docs provides a hosted documentation site per project (web publishing) with features such as multi-version support, project-level and global search, navigable tables of contents, and per-version URLs. Projects can document multiple releases in parallel, allowing enterprises to keep current, legacy, and development documentation available. Localization and internationalization support (i18n / l10n tooling) enables documentation in multiple languages, managed per project.
The open-source service at readthedocs.org (open-source SaaS) is widely used for public documentation, while readthedocs.com offers a commercial SaaS variant (enterprise documentation platform). The commercial offering focuses on private documentation hosting, Single Sign-On (SSO) integration, stricter access control (identity and access management), and enterprise support and SLAs. It is positioned for organizations that need to keep internal documentation behind authentication while using the same build and hosting model as public projects.
From an architectural perspective, Read the Docs operates as a hosted Continuous Integration and Continuous Deployment (CI/CD) system specialized for documentation (continuous documentation delivery). It provides a configuration-driven build pipeline, storage and CDN-backed hosting of static assets (static site hosting), and routing for project and version subpaths. The platform integrates with external version control systems via webhooks and APIs and exposes configuration primitives for controlling environments, build commands, and output formats.
In enterprise and institutional environments, Read the Docs is used to host product documentation, internal developer portals, Application Programming Interface (API) references, and technical guides, all maintained in source repositories. Its interoperability with Git workflows, Sphinx, and related Python documentation ecosystems, along with features for versioning, search, and localization, place it in the categories of developer documentation platforms, documentation-as-code tooling, and static documentation hosting services.
