How we chose these Nuclino alternatives

We looked for open-source tools that give a team a shared wiki with fast editing and linked pages like Nuclino. We verified each project's license, recent activity, stars, and self-hosting in its repository, and flag non-standard licenses. See our methodology for the full criteria.

Closest to Nuclino

Outline is a fast team knowledge base with real-time editing, search, and Slack integration. Docmost is a self-hosted wiki for organizations with real-time editing, SSO, and RBAC, and AppFlowy and AFFiNE combine docs, databases, and whiteboards.

Personal and local-first

SiYuan is a block-based knowledge tool with bidirectional links and encrypted sync, Anytype is a local-first encrypted workspace, and Silverbullet is a self-hosted Markdown system with scripting. Colanode combines chat, pages, and databases with local-first sync.

Other options

Docs is a collaborative document editor with version control, XWiki is an enterprise wiki with structured content and fine-grained permissions, and Orgnise is a project management tool rather than a wiki.

Important: source-available licenses

Outline uses the Business Source License 1.1 and Anytype uses the Any Source Available License 1.0, so neither is open source in the usual sense. AFFiNE's community edition is MIT, with paid plans for teams.

License details

AppFlowy, SiYuan, Docmost, and Orgnise are AGPL-3.0. AFFiNE Community, Docs, and Silverbullet are MIT. Colanode is Apache-2.0 and XWiki is LGPL-2.1.

Maintenance status

Most had commits within days of this update. Colanode's last commit was in April 2026.

Why look for a Nuclino alternative?

Nuclino is a proprietary cloud wiki priced per user, with content stored on its servers. Open-source alternatives can be self-hosted, avoid per-seat pricing, and keep knowledge on your infrastructure, but some are aimed at personal notes rather than team permissions and collaboration.
