What is Lutece?

Lutece is a platform made to help you build Web sites and applications. Created in 2001 by the City of Paris, it was firstly made to be a Content Management System (CMS) which progressively became a toolbox and then a framework for the development of Web applications.

The CMS feature became one of the numerous other modules available.

The source code of Lutece is Open Source since 2002 and fully available on GitHub.

Lutece is based on a fully modular architecture, offering more than 400 plugins

Lutece is or has been used by major public and private sites and many integrators.

Why should i use Lutece ?

Any institution seeking to adopt a new technology for its site must ensure the highest level of guarantees to avoid the risk of being left alone in trouble. Is the code open, is the project monitored and sustainable, can I contribute upstream, can the community help me... are these questions essential for a good choice of a framework.

For Developers


Developers can contribute to Open Source projects that directly impact residents, collaborate with a global community and work on cutting-edge technology challenges.

You feel like there are missing modules, or functionalities? Please consider joining an already (19-year-old) existing project rather than start all over from scratch. We have room for your contributions!

For Integrators


Integrators support city governments to use Lutece and foster cross-city collaboration, as there's no added values in re-selling over and other the same piece of code here and there. As a Lutece integrator, bring your expertise in filling the gaps and develop the specifics, since cities share about 80% of their digital services needs.

For Governements


City governments leaders can access and adapt 400+ digital services/modules created by other cities and organizations accross the globe - from Paris to Baltimore, for free.

Relay on Lutece Core to benefit from all the required to start a new digital service. In no time (therefore few money) you can launch it by simply assembling already existing modules, or, if missing, focus on it and integrate it in the eco-system.

Spend wisely public money, as it should finance public code!
