The trend of self-hosted knowledge bases is on the rise, and it’s easy to see why. Personally, I was a fan of Notion; its functionality was impressive. However, I soon realized that all my notes, plans, and documents were stored on a third-party server, prompting me to seek out self-hosted alternatives that mirrored Notion’s capabilities while ensuring my data remained under my control.
Thankfully, there’s a plethora of self-hosted, open-source note-taking applications available. These tools not only align closely with Notion’s functionalities but also minimize the learning curve for new users.
1. AppFlows
If you’re in search of a solution that closely imitates Notion’s experience, look no further than AppFlowy. It boasts features akin to Notion, such as pages, blocks, Kanban boards, and databases, all while ensuring that you are not reliant on a third-party cloud service.
With a user-friendly interface, AppFlowy performs seamlessly even on less powerful devices. It allows you to manage tasks, meetings, and client information, all from a single platform. The content can be displayed as boards, lists, or calendars, and a variety of templates are provided to kickstart your organization.
Notably, AppFlowy is primarily a desktop application, but you can also self-host it on your server for data synchronization. Additionally, migration from Notion is facilitated through import options.
2. Docmost
For those who utilize Notion for wikis and team documentation, Docmost serves as an excellent self-hosted alternative. It is specifically designed for teams that need a reliable platform for sharing internal knowledge. Like Notion, it offers collaborative features like real-time editing, commenting, and rich text formatting.
Docmost features a clean, functional interface that facilitates the creation of a comprehensive knowledge base through its effective search capabilities and hierarchical structure. It includes built-in version control, ensuring you can track revisions effortlessly. Users can create organized spaces with nested pages and manage document accessibility through permission settings.
3. AFFiNE
Another viable alternative is AFFiNE, which presents a modern and innovative approach similar to Notion. Featuring block-based editing, slash commands, and adaptive databases, AFFiNE focuses on creativity, privacy, and visual project management.
Its highlight, Edgeless Mode, provides a unique dynamic whiteboard experience for brainstorming, mind mapping, and visually organizing ideas using custom shapes and drawing tools.
You can easily self-host AFFiNE via Docker Compose, or choose its desktop app for local data storage with future syncing capabilities.
4. Wiki.js
For teams seeking a developer-centric self-hosted option, Wiki.js is a robust choice. This tool stands out due to its integration with Git for version control, making it especially suitable for technical documentation and collaborative efforts.
It supports rich text, Markdown, and WYSIWYG editing, which eases the transition from Notion. Wiki.js offers features like hierarchical organization, full-text searching, version history, and customizable user permissions to align with many users’ expectations.
While absent of task board functionalities or databases, it remains dedicated to documentation and Internal knowledge sharing through its modular structure, REST API support, and various authentication integrations (Google, GitHub, LDAP, etc.).
5. Logseq
Logseq excels as a self-hosted tool designed for outlining, network-oriented thinking, and sustainable knowledge management. Retaining the block-based editing and page linking features found in Notion, it prioritizes non-linear workflows.
Logseq’s outliner format is exceptional for organizing everything from daily notes to extensive research projects, featuring nested bullet points, querying options, and daily journals to enhance structured content creation over time. The Graph View is particularly notable, visually mapping the relationships among your notes.
Additionally, Logseq supports Markdown storage, flashcards, plugins, and end-to-end encryption. While it lacks collaborative editing features, it provides a focused, private, and extensible knowledge management experience. Users can easily self-host Logseq using its Docker image, allowing web access via a private server.
6. BookStack
Another alternative, BookStack, shifts from Notion’s flexible block system to a more structured, hierarchical format. It organizes content using books, chapters, and pages, making it suitable for those who favor structured documentation.
The editing experience on BookStack is straightforward, providing both WYSIWYG and Markdown formats. It features media embedding capabilities, version history, commenting, and detailed page-level permission management. For those using Docker, self-hosting it with Docker Compose is also straightforward.
7. Trillium Notes
Trilium Notes stands out as one of the most feature-rich self-hosted alternatives to Notion, providing deep hierarchical organization and effective management of numerous interconnected notes.
Moving beyond standard block-based editing, Trilium enables note cloning, custom attribute definitions, workflow scripting, and automation of tasks. Its note editor supports tables, checklists, code blocks, and embeds, while a visual graph view simplifies the understanding of note relationships.
In addition to end-to-end encryption and device synchronization, Trilium features robust version control. While it may not have the polished interface of Notion and carries a steeper learning curve, it offers advanced users remarkable control over their data. You can self-host Trilium using Docker or opt for a standalone installation; I found that Docker Compose made the procedure quick and easy.
Conclusion
While self-hosting may initially appear daunting and requires some setup effort, the benefits of control, privacy, and flexibility far outweigh the initial challenges. Each of these tools serves as a commendable alternative to Notion, and they represent only a small fraction of what I am able to self-host on my homelab server. If you’re curious, feel free to explore what other applications I have implemented in my homelab.
