Multiple authors can edit the same LaTeX document simultaneously in the browser with live cursor tracking, conflict-free merging, and instant PDF compilation on every save. Overleaf Community Edition brings the collaborative editing experience that millions of researchers and academics rely on, with no compile time limits, storage quotas, or collaborator caps imposed by the hosted tiers. The web editor provides syntax highlighting, auto-completion, and bracket matching alongside an integrated PDF preview panel powered by a bundled TeX Live distribution supporting pdfLaTeX, XeLaTeX, and LuaLaTeX engines. The file tree panel organizes multi-file projects with separate files for chapters, figures, bibliography references, and style definitions. BibTeX and Biber handle bibliography management, and detailed compilation logs offer clickable error navigation to the exact source line causing each issue. Users upload images, PDFs, and data files directly through the browser, and a template gallery provides starting points for journal articles, conference papers, theses, presentations, and CVs. Over 17,800 GitHub stars and a decade of active development anchor the project. The application runs as containerized microservices including the Node.js web application, MongoDB for persistence, and Redis for session management. 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.

In TeXlyre, two coauthors edit the same LaTeX or Typst file at once, and the PDF compiles inside the browser tab instead of on someone else's server. Start from a template: arXiv preprint, IEEE paper, Tufte book, Beamer deck. pdfTeX, XeTeX, and LuaTeX compile with BibTeX and Biber. Errors turn into readable cards that jump to the failing line. Live cursors show who is typing where. A shared link brings coauthors in, no accounts needed. Chat sits beside the editor, and comments can be discussed and resolved. Tracked insertions and deletions land in a review panel to accept or reject. Draw.io and TikZ editors open inside the project for shared diagrams. MathLive edits a formula under the cursor with a virtual keyboard. A bibliography panel tidies BibTeX, matches DOIs, and imports from Zotero and OpenAlex. Large files travel straight from one collaborator's browser to another. Projects export as ZIP, sync to a local folder, or back up to GitHub, GitLab, Gitea, and Codeberg. Vim, Emacs, and Helix keybindings are one setting away. The app installs as a progressive web app and works offline. Language servers like LTeX LS Plus, Harper, and Tinymist plug in through recipes beside your own signaling and TeX Live package servers.
