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.

A solution that allows innovation

There is an increasing need to quickly create new services for which there is no software available on the market. With Lutece, it is very easy to create new applications by reusing numerous modules and by writing a minimum number of lines of code which can be inspired by hundreds of thousands of existing lines.

A mature and proven solution

Lutece has been used in production for many years in various contexts where security and performance are key. All the modules meet a wide range of real life use cases.
More than 200 developers have participated in its realization and have brought their expertise.

An Open Source solution

Lutece is completely Open Source and free to use. There is no vendor lock to its use and you can stay in control of the whole code and guarantee the sovereignty of your investments.
Moreover, the dynamics of an Open Source community allows you to benefit from contributions from all sides which enrich a basis of commons.

A stable, resilient and sustainable solution

Lutece integrates the latest technological evolutions while maintaining the compatibility with older applications in order to manage the application assets over the long term. With Lutece, you will not have to rewrite your applications every three years and your information system will be greatly streamlined and urbanized.


Lutece is available for all to use. Developers, integrators, city government officials or simply someone who has a great idea for a project in their community. That’s where you come in.

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 City Governments

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!

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.
