An open-source online real-time collaborative LaTeX editor.
Overleaf is an open-source online real-time collaborative LaTeX editor. We run a hosted version at http://www.overleaf.com, but you can also run your own local version, and contribute to the development of Overleaf.
If you want help installing and maintaining Overleaf at your university or workplace, we offer an officially supported version called Overleaf Server Pro. It also comes with extra security and admin features. Click here to find out more!

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
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.
sharelatex/sharelatex image extends the base image and adds the actual Overleaf code
make build-base and
make build-community 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
manager to manage services, and we add our init-scripts from the
