Gramax vs Wiki.js

Gramax

• Teams that want documentation kept as Markdown files in their own Git repository
• Product and developer documentation published as a reader portal
• Companies with many readers and few authors, since only editors need a license

Wiki.js

• Developer teams that prefer writing documentation in Markdown
• Organizations that want a free wiki on their own infrastructure
• Wikis whose content should be mirrored to a Git repository

Gramax

• Corporate SSO, admin-panel access management, analytics, training tests and portal notifications are limited to Enterprise Server.
• Enterprise Server has a 10-license minimum, so the smallest purchase is $200 a month or $7,000 one-time.
• In the open-source version the AI agent and AI search run on a model you supply.
• Sharing work between people depends on a Git storage, and the docs list browser and desktop versions but no mobile apps.

Wiki.js

• The site offers two ways to run it, self-hosting or a DigitalOcean Marketplace image, and lists no managed hosting plan or paid support.
• It requires a dedicated domain or sub-domain and cannot be mapped to a subfolder of another site.
• MySQL, MariaDB, MS SQL Server and SQLite will not be supported in the next major version, which keeps only PostgreSQL.
• Version 3.0 is still in beta, and several listed modules, such as the WikiText and tabular editors, are marked as coming soon.

Gramax

Visual editor over Markdown and Git

Articles are edited visually and saved as Markdown files. Syncing and publishing run on Git commands built into the interface, against GitHub, GitLab, Gitea or another Git storage.

Documentation portal

Catalogs are published as a site for readers through Gramax Cloud, a Docker container on your own server or a static site. Portals and readers are unlimited in both versions.

Diagrams, templates and fragments

Articles can include Diagrams.net, Mermaid and PlantUML diagrams, start from article templates and reuse fragments of content across articles.

Versions and change approval

Catalogs keep versions and a change history, and an edit proposed by an author or the AI agent is reviewed line by line before it is accepted.

AI search and AI agent

Readers ask a question and get an answer with links to the source articles, and the agent flags duplicates and conflicts. The free version runs on your own model; Enterprise needs no model setup.

Training and metrics

Enterprise Server adds questions inside articles with test results per employee, plus visit history, search queries and click-through rates for finding gaps.

Wiki.js

Three editors

Pages can be written in Markdown with a live preview, in a visual WYSIWYG editor meant for non-technical people, or directly in HTML.

Version tracking

All content changes are tracked. Two versions of a page can be compared visually, and a page can be reverted to an earlier state or recovered after deletion.

Authentication modules

Sign-in can use local accounts, services such as Google, GitHub and Slack, or LDAP, SAML, Okta and Azure AD, with two-factor authentication on supported modules.

Git and cloud storage sync

Content can be synchronized or backed up to Git services such as GitHub and GitLab, or to storage such as AWS S3, Azure Blob Storage and Google Cloud Storage.

Groups, permissions and page rules

Users are placed in groups with granular permissions, and page rules limit a group's access by exact path, by how a path starts or ends, or by regular expression.

GraphQL API

A GraphQL endpoint on each wiki reads and modifies all of its resources, using API tokens with permission scopes that are generated in the administration area.
