ikiwiki

ikiwiki is a self-hosted wiki compiler for publishers who want editable source pages turned into a fast, controllable website. It fits technically confident individuals and small teams who can manage hosting and configuration, rather than readers seeking a managed collaboration service.

Overview

ikiwiki converts wiki pages into HTML and republishes the site when source files change. You can keep revisions in Git or Subversion, or omit a revision-control system entirely, giving personal wikis, blogs, and documentation sites a choice between history and a simpler setup. The project is free, open source, and licensed under GNU GPL version 2 or later.

The setup tutorial describes creating a functional wiki with one command, while advanced users can configure it manually. Packages are provided for Debian or Ubuntu, Fedora, BSD, openSUSE, Arch Linux, Homebrew, and Guix. A forum, bug tracker, TODO list, and discussion pages provide project support, with developers monitoring RecentChanges.

Key features

Markdown is the default markup. Plugins can add WikiText, HTML, reStructuredText, and Textile, along with directives, revision-control backends, and CGI functionality. This plugin architecture is the main reason to choose ikiwiki when a standard wiki is too restrictive, but it also makes the final system depend on the extensions and configuration you select.

Any page can operate as a blog and produce RSS or Atom feeds, so a single installation can combine reference pages with news publishing. Templates, CSS, and themes control the generated site's appearance and layout. Full-text search can be added through Xapian, useful when a growing static output becomes difficult to navigate.

Optional web editing supports registration, OpenID and HTTP basic authentication, and configurable page edit controls. Page-level permissions help separate public content from restricted areas. The trade-off is operational responsibility: the project's security guidance warns that allowing other people to edit introduces risks around configuration and uploaded content, and notes that Perl taint checking is disabled in production builds because of a Perl bug.

Pricing

The ikiwiki plan costs free. It is free software with no paid plans stated, no trial period, seat charge, storage quota, or renewal term. You supply and administer the hosting yourself, so this price removes licensing cost rather than infrastructure or maintenance work.

Platforms

ikiwiki runs on Linux and macOS, supports self-hosted deployment, and provides a web interface for editing and publishing. Custom domains and SSO support are available, making it possible to present the generated site under your own address and connect access to an existing identity setup.

Who it's for

Choose ikiwiki for a personal wiki, blog, or documentation site when static publishing, optional Git or Subversion history, and deep markup and theme customization matter more than a turnkey service. It is especially suitable for administrators comfortable with Linux-style packages, web configuration, and access controls. Readers who want vendor-managed hosting, built-in operational safeguards, or a polished team workspace should look elsewhere.

Pros and cons

Pros

• Static HTML publishing: source changes become generated pages, a useful model for controlled website delivery.
• Revision flexibility: Git or Subversion history is available, but not mandatory.
• Extensible formats: plugins add multiple markup languages, directives, backends, and CGI features.
• Blog and feed support: any page can publish RSS or Atom feeds.
• Free and self-hosted: there is no software charge, and custom domains and SSO are supported.

Cons

• Security burden: public editing requires careful authentication, permissions, and upload configuration.
• Configuration complexity: plugin-driven capabilities reward experienced administrators and can make deployments less predictable.
• No managed service: hosting, updates, backups, and runtime administration remain your responsibility.

Verdict

Look elsewhere if you need a managed workspace or do not want to own the security and administration involved in enabling collaborative editing.
