Obsidian vs Kuku
Kuku is the stronger fit for macOS users who want an MIT-licensed, inspectable and self-hostable Markdown workspace with reviewable AI editing. Obsidian remains the safer choice for users who need documented shared vaults, hosted web publishing, or broader cross-device availability now; Kuku’s Windows, Linux, mobile, real-time collaboration and team-workspace coverage is either forthcoming or planned.
Decision guide
The practical reasons to choose either option, based on documented capabilities.
Choose Kuku if
- macOS users who keep knowledge in local Markdown files and want wikilinks, backlinks, full-text search and graph navigation
- Users who require MIT-licensed client, server and infrastructure code that they can inspect or modify
- Operators prepared to maintain a Docker-based self-hosted sync stack without Kubernetes support recorded in the supplied facts immediately after December 2026 until at least March 2027, unless the maintainers publish a 1
Stay with Obsidian if
- You need hosted publishing for a wiki, documentation site, knowledge base or digital garden; no equivalent Kuku feature is documented
- You need shared vaults and real-time team updates today; Kuku lists real-time collaboration and team workspaces as future work
- You require native Windows, Linux, iOS or Android access now; Kuku currently documents only macOS as supported
Deployment and operations
Kuku’s official desktop build currently supports macOS and can be installed from its website, Homebrew tap or GitHub Releases; Windows and Linux are marked as coming soon. The supplied repository facts identify an MIT license, Docker support and no Kubernetes support. The repository includes the web app, server, contracts, indexing/AI components and Docker infrastructure for self-hosting, so self-hosters are responsible for operating that stack. Managed service tiers are described separately,pre
Migration considerations
Kuku opens ordinary .md files in a local vault, and its README explicitly says those files work with Obsidian. This supports file-level reuse of Markdown notes, but the supplied sources do not document an automated Obsidian importer or compatibility for plugins, settings, graph metadata, Sync or Publish configurations.
