What it is

Docny is a hosted documentation CMS for developer teams, combining authoring, publishing, hosting and analytics. Content can be written in a WYSIWYG block editor or code-first MDX. Guardian AI scans repositories, URLs, code comments and READMEs to create structured documentation and identify drift. API references support OpenAPI 3.1 and Swagger 2.0, with interactive explorers and re-rendering when linked specifications change. Managed hosting includes SSL, global CDN delivery, custom domains, versioning and one-click publishing. Teams get real-time cursors, inline comments and suggestion resolution, while published sites can include an AI assistant for reader questions. Analytics show popular pages, searches, traffic trends and drop-off points. Integrations include GitHub, Discord, Jira, Algolia, Slack, Notion, Intercom and Linear, plus a public API. Hobby costs £0/mo for one project; Pro costs £45/mo and adds unlimited projects and collaboration features.
