Docny
What Docny is
Docny is a hosted documentation CMS for developer teams, combining authoring, publishing, hosting, and analytics. Teams can write with a visual block editor or code-first MDX, then publish documentation sites and interactive API references. Guardian AI scans GitHub repositories, URLs, code comments, and README files to generate structured documentation and detect drift. API references support OpenAPI 3.1 and Swagger 2.0, with interactive explorers and re-rendering when a linked specification changes. Managed hosting includes automatic SSL, global CDN delivery, custom domains, versioning, and one-click publishing. Teams can collaborate in real time with live cursors, comments, and suggestion resolution, and add an AI assistant for readers of published docs. Analytics cover popular pages, searches, traffic trends, and reader drop-off. Integrations include GitHub, Discord, Jira, Algolia, Slack, Notion, Intercom, and Linear, alongside a public API. The free Hobby plan is £0/mo for one documentation project. Pro costs £45/mo and includes unlimited projects, team collaboration, Guardian AI without a credit gate, AI chat, doc audits, and priority support. Docny is available on web and API platforms.
