Wiki.js is a next-generation open-source wiki platform built on Node.js with a Vue front end. This repository contains the upcoming 3.0 release in beta, and the README is explicit that it is not for production use. The current stable 2.x release is published at js.wiki and in a separate repository.

The project is aimed at documentation and knowledge sharing for teams. Topics list Markdown editing, Git, cross-platform operation and documentation, and the beta is accompanied by installation requirements, a changelog and a feature request channel. Contributors can help with translations, and the project is supported by sponsors, patrons and donations from the community.

Wiki.js is AGPL-3.0 licensed. It is software you run on your own server, so it suits teams that want a self-hosted wiki they control. Anyone who needs a dependable wiki today should look at the 2.x stable version rather than this beta, and treat the 3.0 code as a preview of what is coming.

BookStack is a platform for storing and organizing information and documentation, built with PHP and the Laravel framework. It is deliberately opinionated: the aim is a pleasant, intuitive experience out of the box where only basic word-processing skills are needed to create content, so non-technical colleagues can contribute.

Content is organized in a book metaphor, with shelves, books, chapters and pages. Advanced capabilities are available for those who want them, but the project says they should never get in the way of the simple core experience, and it is not intended as a general extensible platform for unrelated purposes. Development is relaxed and positive, evolving slowly while keeping upgrades stable and easy. There is a demo instance, installation instructions, documentation and a blog.

BookStack is licensed under MIT and is now managed on Codeberg, which is where the primary repository and issue list live. You host it on your own server with PHP and a database. It suits teams, schools and small organizations that want an approachable internal wiki rather than a highly configurable knowledge system.

PandaWiki is an open-source system for building knowledge bases, powered by large language models. It helps teams quickly set up product documentation, technical documentation, FAQs and blog sites, and uses AI to assist with writing, answering questions and searching the content.

The editor supports Markdown and HTML and can export to Word, PDF and Markdown. Sites can be embedded in other websites as a widget or turned into chatbots for DingTalk, Feishu and WeCom. Content can be imported from web page URLs, website sitemaps, RSS feeds and offline files. A knowledge base is a collection of documents from which PandaWiki builds a separate wiki website, and AI features need an LLM to be configured at first login.

To self-host it you need a Linux server with Docker 20.x or newer and run the installer as root. A SaaS version also exists for those who prefer not to deploy it. PandaWiki is licensed under AGPL-3.0, so modifications and network services built on it must also be open source, and the project documentation is mainly written in Chinese.

Cortex turns API specifications and Markdown files into developer-facing outputs from a single project configuration. It reads sources such as OpenAPI, AsyncAPI, GraphQL, Protocol Buffers, OpenRPC, and plain Markdown, and produces interactive documentation for people, typed SDKs for applications, and an MCP server so AI agents can work with the same project context. It is released under the MIT license.

Generated SDKs cover many languages, including TypeScript, Python, Go, Java, Kotlin, Ruby, PHP, Rust, and C++, and can combine several specification files into one client. The tool supports HTTP, WebSocket, GraphQL, gRPC, and JSON-RPC clients, and builds static HTML documentation with interactive API reference pages. The MCP server includes typed tools, embedded specifications, and SDK guides.

You can try a local demo in about a minute, keep documentation in Git, and publish a free site for a public GitHub repository through the project's hosting flow. It suits API providers and developer-experience teams who want one source of truth for docs, client libraries, and agent access.

Vrite is an open-source, collaborative space to create, manage, and deploy product documentation, technical blogs, and knowledge bases. It aims to provide a high-quality, integrated experience for both writers and developers. This repository is described as a work-in-progress branch for Andesine, the version 2 rewrite, and the README points to the main branch for the latest stable Vrite. The input lists its license only as other.

Features listed include a built-in dashboard to manage content production and delivery using Kanban or list views, a modern WYSIWYG editor with Markdown support, an integrated code editor with formatting, and real-time collaboration. AI-powered semantic search helps organize and find content, and a versatile API serves content to websites and applications, which is why topics call it a headless CMS.

A hosted Vrite Cloud is available alongside the self-hostable code. It suits technical writers, developer relations teams, and documentation groups who want a content workflow that bridges writing and publishing.

Gramax is a free, open-source application for creating, editing and publishing documentation as code. It stores all data locally in Markdown, so it works offline and files can be edited in any text editor, and it integrates with Git for version control and collaboration. It targets product documentation portals, internal knowledge bases, project documentation and personal notes.

A visual editor makes Markdown editing easier for technical and non-technical users. The app runs on Windows, macOS and Linux as a desktop app and as a web version. Editing features include tabs, tables, video embeds, code blocks, diagrams from Mermaid, Excalidraw and Diagrams.net, and Swagger API descriptions. Git repositories on GitHub, GitLab, Bitbucket, Gitea and others can be connected, catalogs can be published to a customizable documentation portal, documentation can be written in 17 languages, and content can be imported from Confluence and Notion.

Gramax is positioned as an alternative to GitBook, Mintlify and typical static site generators. It is written in TypeScript and Rust with Tauri, and licensed under GPL-3.0.

Documize Community is an open-source, self-hosted knowledge management product aimed at both technical and non-technical users. It is meant to unify customer-facing and internal documentation, organizes content through labels, spaces and categories, and is positioned as a modern alternative to Confluence.

It is written in Go and Ember.js and compiled to a single executable for Linux, Windows and macOS, including a Raspberry Pi ARM build. You supply the database, which can be PostgreSQL, Microsoft SQL Server, SQL Azure or a MySQL variant such as Percona or MariaDB, with full-text search required. Besides email and password, sign-in options include LDAP, Active Directory, Keycloak and CAS.

A Community+ edition adds enterprise features such as approval workflows, version and lifecycle management, feedback capture, PDF export, analytics, activity streams, audit logs, action assignments and support. The README states it is free for the first five users, then starts at 900 US dollars annually for 100 users. The Community edition is AGPL-3.0 licensed.
