Personal wiki software I've considered or have seen recommended

• Gollum: "A simple, Git-powered wiki with a sweet API and local frontend."
• ikiwiki: "Ikiwiki is a wiki compiler. It converts wiki pages into HTML pages suitable for publishing on a website. Ikiwiki stores pages and history in a revision control system such as Subversion or Git."
• Zettlr: "A powerful Markdown editor for researchers and journalists."
• Markdown and a git forge: gitlab or github do pretty printing of markdown pages in your repo (and org pages too, as it happens)
• TiddlyWiki: "A non-linear personal web notebook". Looks like it fulfils the usecase pretty well, and appears to have a plugin for git integration.
• [[org-brain]]: I tried org-brain a few times, and it never really clicked for me.
• [[Roam]]: what org-roam is based on.
• [[FedWiki]]
