Community Edition
Overleaf is an open-source online real-time collaborative LaTeX editor. We run a hosted version at www.overleaf.com, but you can also run your own local version, and contribute to the development of Overleaf.
Enterprise
If you want help installing and maintaining Overleaf in your lab or workplace, we offer an officially supported version called Overleaf Server Pro. It also includes more features for security (SSO with LDAP or SAML), administration and collaboration (e.g. tracked changes). Find out more!
Keeping up to date
Sign up to the mailing list to get updates on Overleaf releases and development.
Installation
We have detailed installation instructions in the Overleaf Toolkit.
Upgrading
If you are upgrading from a previous version of Overleaf, please see the Release Notes section on the Wiki for all of the versions between your current version and the version you are upgrading to.
Overleaf Docker Image
This repo contains two dockerfiles, Dockerfile-base, which builds the
sharelatex/sharelatex-base image, and Dockerfile which builds the
sharelatex/sharelatex (or "community") image.
The Base image generally contains the basic dependencies like wget, plus texlive.
We split this out because it's a pretty heavy set of
dependencies, and it's nice to not have to rebuild all of that every time.
The sharelatex/sharelatex image extends the base image and adds the actual Overleaf code
and services.
Use make build-base and make build-community from server-ce/ to build these images.
We use the Phusion base-image
(which is extended by our base image) to provide us with a VM-like container
in which to run the Overleaf services. Baseimage uses the runit service
manager to manage services, and we add our init-scripts from the server-ce/runit
folder.
