Overleaf

The software provides a web‑based environment for editing LaTeX documents collaboratively in real time. Users can work together on the same project, see each other's changes instantly, and benefit from built‑in version control and commenting features. It supports both a visual editor for point‑and‑click formatting and a code editor for direct LaTeX input, along with a large collection of ready‑made templates.

It is released under the AGPL‑3.0 license, can be self‑hosted, and offers a free tier without requiring a subscription. The project includes Docker images for easy deployment, and the core services run inside a container based on the Phusion base image with the runit service manager. Documentation covers installation, upgrading, and optional sandboxed compilation for enhanced security.

The platform targets researchers, students, and technical writers who need to produce complex, mathematically rich documents and want to collaborate without installing LaTeX locally. It is suitable for environments where all participants are trusted, while an enterprise version adds features such as SSO, LDAP/SAML integration, and tracked changes for more controlled settings.
