In their own words
PmWiki
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.
TiddlyWiki
TiddlyWiki is a free, non-linear notebook and interactive wiki for organizing and sharing notes, to-do lists, projects, and websites. It stores information in small units called tiddlers, which can be linked and grouped with tags, lists, and macros. Search spans tiddlers and supports filtering system and shadow tiddlers. In its single-file form, the data and code are held in one HTML file that runs in a browser without installation or external dependencies. Users can import material from files or other TiddlyWiki windows, and extend a wiki with plugins, themes, colour palettes, widgets, and macros. It can also run as a Node.js application; that setup offers more capability but takes more technical knowledge to set up and maintain. Saving choices vary, including storage and sync options such as Google Drive, iCloud, Dropbox, and Syncthing. The built-in encryption for single-file wikis has not undergone rigorous third-party testing. TiddlyWiki is available across web, mobile, desktop, and self-hosted setups.
