Wiki.js

open sourcewebself-hosteddocker to self-host

A polished wiki, provided you are willing to become its part-time sysadmin.

licenseAGPL-3.0

runsyour server

installDocker Compose with PostgreSQL, or a Node.js package plus a supported database

dataPages, users, authentication data, and history in the configured database; optional storage modules can mirror content and assets to Git, local disk, or cloud storage

the catch vs NuclinoIt provides a capable wiki but not Nuclino's lightweight canvas, graph and board workflow, and it asks someone to administer a database-backed server.

setupYou must provision a database and persistent volumes, then configure backups and a TLS reverse proxy for public use

D

Docmost

open sourcewebself-hosteddocker to self-host

A clean team wiki with a database bill instead of a seat bill.

licenseAGPL-3.0

runsyour machine or their cloud

installHosted signup or Docker Compose with PostgreSQL and Redis

dataPages, users, comments, and history in PostgreSQL; jobs/cache in Redis; attachments in a persistent local volume by default or S3/Azure Blob

the catch vs NuclinoIt is a strong document wiki, but its boards, visual graph and real-time product polish are less mature than Nuclino's tightly integrated workspace.

setupSelf-hosting requires Docker, a strong APP_SECRET, database credentials, persistent volumes, and normally a domain, TLS reverse proxy, and SMTP

B

BookStack

open sourcewebself-hosteddocker to self-host

A wiki arranged like a bookshelf, which is either charming or compulsory.

licenseMIT

runsyour server

installFresh Ubuntu install script or manual PHP/MySQL setup

dataPages, users, permissions, and settings in MySQL/MariaDB; uploaded images and files in the server filesystem or configured object storage

the catch vs NuclinoIts shelf/book/chapter hierarchy is much more rigid than Nuclino's free-form collections, linked graph, canvas and board views.

setupThe official script expects a fresh Ubuntu host; manual installs require PHP extensions, a database, writable storage, mail, and TLS

why people still pay for Nuclino

People still pay for Nuclino because people keep paying when the note system is trusted across every device and disappears into their daily capture habits. The recurring cost buys file watching, conflict handling, indexing, mobile apps, encryption, backups, and migrations, not just the visible interface. If none of that applies to you, any pick above saves $72 a year.
