Folio is a self-hosted team wiki that stores every page as a plain Markdown file in a Git repository you own, while your team writes together in the browser in real time. People work in Reading, Live edit, or Source mode, keep editing offline until the connection returns, and watch changes land in the page history as commits they can restore. Data tables with nine column types, filters, and views sit beside the documents, and forms write submissions straight into those tables without requiring an account. Whiteboards, Mermaid diagrams, and a visual diagram editor cover the pictures, while uploads like PDF, Word, Excel, and PowerPoint files open as previewable pages inside the tree. Confluence spaces import with their trees, images, and whiteboards converted, so a migration keeps its structure instead of flattening into a pile of attachments. AI agents read and write the same pages through an MCP server with 41 tools, authenticated by personal tokens or OAuth 2.1, and the built-in assistant answers questions read-only or makes supervised edits. Administrators control access down to a single page, sign people in with SAML, SCIM, or OpenID Connect, hand out expiring share links, and publish a space as a public read-only website. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. MIT licensed.
