f451
f451 at a Glance
f451 combines the comfort of a wiki with Git as the single source of truth. Every page is a Markdown file in a repository on Forgejo or GitHub. The repository decides who may read and who may approve. Like code, every change goes through a draft and a review before it is published.
Features
- Git as the source. A space is a repo, a page a folder with
index.md. The database is only an index and can be rebuilt from Git at any time. - Draft, review, merge. A draft is a branch, a review a pull request, the approval a merge. Conflicts are shown, never silently overwritten.
- Permissions from the Git provider. No role model of its own. Commits are made under the personal account, never under a service account.
- Editor with two modes. WYSIWYG on Tiptap and raw Markdown, autosave, local buffer when the connection drops.
- AI agents via MCP. Agents read, search, and write drafts on the same review path as people.
- Reading and navigation. Page tree, full-text search in German and English, knowledge graph, broken-link report, diagrams with draw.io and Excalidraw.
