Overleaf locks its best collaboration tools behind a paid server license, and AyakaLeaf Pro is the open-source edition that hands them to your own server instead. You get the familiar online LaTeX editor, with several people typing in the same document at once, but compilation runs in an isolated Docker sandbox with a full TeX Live image, so a runaway document cannot take the service down and compile times are yours to set. Reviewers work the way they do in a word processor: track changes, comment in the review panel, and roll back through full project history with restore and download. Projects stay connected to the rest of your workflow through two-way sync with GitHub, GitLab, Gitea, and Dropbox, a git-bridge for clone, pull, and push, and reference managers through Zotero and Mendeley with searchable bibliography entries. A template gallery lets you publish house styles for your lab or department, the symbol palette inserts math notation in one click, and an AI chat assistant plus a compile-error assistant help inside the editor, while an MCP server lets external AI agents edit and compile too. Administrators get SSO through LDAP, SAML, or OAuth, domain-limited self-registration, and a panel for users and projects. Running on a dedicated VPS on RepoCloud with guaranteed CPU, RAM, and SSD, full root SSH access, and a browser serial console. AGPL-3.0 licensed.
