Confluence vs PmWiki

Confluence is Atlassian's workspace for knowledge management and project collaboration, with pages, whiteboards, databases and Loom video messaging. Teams can edit content together in real time, comment, and receive notifications when tagged or assigned tasks. Its Jira connection links project tracking with documentation planning, and whiteboards can turn ideas into Jira work. View-only pages can be shared publicly; version history, content analytics and app integrations are also available. Rovo can turn content into timelines, charts, maps, slides and prototypes, while its connectors bring knowledge from services including Google Drive, Slack, Salesforce, GitHub, Microsoft Teams and SharePoint into AI search and workflows. Cloud products are hosted, while Data Center products can run on infrastructure of your choice. The Free plan supports up to 10 users, includes 2 GB of storage and allows three active whiteboards per user. Confluence is available on web, Android, iOS and as self-hosted software. Pricing starts at $5.42/user/mo, and a 7-day trial is listed.

PmWiki is a wiki-based content-management system for collaboratively building and maintaining websites. Contributors can add and edit pages through the web without knowing HTML or CSS. Administrators can set password controls for an entire site, page groups, or individual pages, covering reading, editing, and uploads. Its access controls can work with existing password databases such as.htaccess, LDAP, and MySQL. Pages are stored as flat files, so a database is not required; the project says it can handle thousands of pages. Administrators can alter appearance and functions with skins, HTML templates, and extensions called recipes. Page histories include restore links, and the number of history days and revisions can be configured. PmWiki is free, open-source software for self-hosting that requires PHP. The listed plan is free. Project support resources include a FAQ, troubleshooting guide, error-message descriptions, and mailing lists. Maintainer Petko Yotov offers paid technical support and development at €60, paid once, billed at 60€ / hour, with an invoice provided. The release notes list version 2.7.6, dated 2026-09-18, with updates for recent PHP versions; version 2.7.5 closed a Windows-server vulnerability under specified conditions.
