Open-source Bloomfire alternatives

Outline is a knowledge base for teams, built with React and Node.js. It focuses on fast, collaborative writing: documents are edited together in realtime, stay compatible with Markdown, and are organized into collections so a growing team can find what it has written down.

The maintainers offer a hosted version at getoutline.com, and the repository contains the source that runs Outline and its associated services. If you only want to use Outline you do not need to run the code yourself, while teams that want their own copy can follow the documentation for a production configuration and use the published container images. Topics also mention a Slack integration.

The repository license is listed as 'Other', so review it before commercial redistribution. Outline suits teams looking for a wiki or internal documentation tool with a clean editor, as an alternative to products such as Confluence or Notion for company knowledge. The project does not accept AI-generated pull requests.

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.

Docmost is a collaborative wiki and documentation tool, open source and presented as an alternative to Confluence and Notion with a focus on secure, on-premise use. Teams write and organize knowledge together in real time, and the project emphasizes that its self-hosted deployment fits organizations with strict compliance requirements.

Its feature list covers real-time collaboration, diagrams through Draw.io, Excalidraw and Mermaid, spaces for organizing content, permission management with groups, comments, page history, search, file attachments and embeds for tools such as Airtable, Loom and Miro. The interface is translated into more than ten languages. Topics mention an AI feature, real-time collaboration and drop-in migration from other wikis.

The Docmost core is licensed under AGPL-3.0, while enterprise features sit in specific directories under a separate enterprise license. You can follow the documentation to self-host it or try the cloud version. It suits teams looking for an internal knowledge base or documentation hub with a lighter footprint than Confluence.

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.

GROWI is a team collaboration wiki built around Markdown. Teams create hierarchical pages, write them in a Markdown editor, and edit the same page at once with several people, which makes it useful as an internal knowledge base, documentation site or shared notebook.

It offers authentication through LDAP, Active Directory and OAuth, single sign-on via SAML, and integrations with Slack, Mattermost and IFTTT. Plugins can be installed from npm or GitHub, and full-text search is available through Elasticsearch. The topics also tag AI features. The project began as a continuation of Crowi, and a migration guide for Crowi users is provided.

GROWI is written in TypeScript with Node.js and React, uses MongoDB as its database, and is licensed under MIT. You run it yourself, with Docker Compose recommended for production, a Helm chart marked experimental, and on-premise installation guides for Ubuntu and CentOS. A demo site and documentation are available. It suits organizations that want a self-hosted, Markdown-first wiki with enterprise login options.

XWiki Platform is a generic wiki platform that offers runtime services for applications built on top of it. It is written in Java and licensed under LGPL-2.1. XWiki Commons, XWiki Rendering and XWiki Platform are part of the XWiki.org software forge, and they are released together and share the same version number.

The project provides separate guides for developers, administrators and users, an API reference, a development zone and release notes. Download and installation instructions are published on the platform site. The most recent release listed in the data is xwiki-platform-16.10.19.

Development tools include continuous integration that builds each commit, an issue tracker that is not GitHub Issues, and a documented development flow. The project invites contributions through a Get Involved guide and offers a forum and chat for the community, plus a blog with news. A project health page shows further statistics.

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.
