Open source alternative to Notion
People searching “open source alternative to notion” usually want a workspace they can self-host or keep local, not another hosted wiki.
Notion bundles pages, databases, boards, and personal notes into one SaaS product. The open-source tools in this directory split that job: AppFlowy is the closest all-in-one workspace, AFFiNE adds a Miro-like canvas, Outline and Docmost are team wikis, and Logseq and Trilium are personal knowledge bases. Boards and task apps sit further out. This directory currently lists 13 mapped tools, led by AppFlowy (61.3k GitHub stars).

How these Notion alternatives differ
Star rank is useful for adoption, not for picking a job. Use the diffs below to match the slice of Notion you actually need.
All-in-one workspace
AppFlowy
Closest Notion-shaped workspace in this catalog: projects, wikis, and teams with the option to keep data on machines you control.
Docs plus canvas
AFFiNE
A knowledge base that also covers the whiteboard slice Notion does not. Reach for AFFiNE when the page and the board need to live together.
Team wiki
Outline
Realtime, markdown team docs with permissions. Closer to Confluence than to a personal Notion workspace.
Collaborative wiki
Docmost
Self-hosted team documentation with realtime editing and access control. Pick it when the job is a company wiki, not a personal database.
Local-first outliner
Logseq
Privacy-first personal knowledge. Closer to Obsidian or Roam than to Notion databases — daily notes and a graph, not team pages.
Personal knowledge base
Trilium
Hierarchical notes, sync, and scripts for a single-user knowledge tree. Not a collaborative Notion replacement.
Project suite
Platform
Huly covers the Linear / Jira / Slack slice and only overlaps Notion where Notion is used as a project tracker.
Boards
Focalboard
Self-hosted cards and boards (Trello / Asana shaped). Use it for kanban, not for a wiki or databases.
Tasks and time
Super-productivity
A todo list with timeboxing and issue-tracker hooks. It is not a workspace or a knowledge base.
Bookmarks and clips
Karakeep
Save links, notes, and images with search. Replaces Notion-as-a-clipper, not Notion-as-a-workspace.
