0docs vs Writerside

0docs is a free, open-source documentation platform that teams can self-host to create, style, version, and publish documentation. Its MIT-licensed editor arranges content into pages, sections, and blocks such as callouts, steps, code tabs, cards, accordions, and API endpoints. Users can change colors, fonts, sidebar presentation, and individual block styles, then publish documentation snapshots using a custom domain. The “Ask docs” feature answers questions from published documentation and requires an OpenAI API key; an OpenAI-compatible base URL override is documented. AI clients can use a built-in MCP endpoint to read and edit documentation with project tokens or anonymous read-only access. The platform requires PostgreSQL, storing uploaded media there by default or in optional S3-compatible storage. Local installation calls for Node.js 20+ and pnpm, plus Docker Compose or PostgreSQL 14+. The default upload maximum is 20 MB per upload. SMTP is optional, but without it password-reset and invitation links appear in server logs. The self-hosting guide recommends HTTPS, database backups, and production configuration.

Writerside is a tool for authoring, building, testing, and publishing technical documentation. It is now a plugin for JetBrains IDEs, not a standalone IDE; the plugin retains the standalone product's features and adds editor support and validation for supported code samples. Its components include an authoring plugin, a documentation builder, and a frontend for rendering help websites. Writerside supports Markdown and semantic markup, with single sourcing that lets teams reuse topics, sections, markup elements, filters, and variables across outputs. Built-in Git integration can automate builds, testing, and deployment with GitHub or GitLab hosting. A Docker builder can also support CI/CD pipelines, with instructions for GitHub, GitLab, and TeamCity. Writerside can generate PDFs with a table of contents and optional cover, header, and footer, and create API entity references from OpenAPI specifications. Local previews include search; published documentation uses an external search service by default. AI writing actions require the Grazie Pro plugin. The free plugin supports Linux, macOS, and Windows through JetBrains IDEs.
