An Open Community Service Platform

las2peer is a Java-based Open Source framework for distributing community services in a peer-to-peer infrastructure. It is being developed by the ACIS Group which is part of the Chair of Computer Science 5 at RTWH Aachen University. Main goals are easy development and deployment of services.



las2peer is a peer-to-peer network with no central instance that controls the network.


The network hosts multiple services that communicate with each other. It's easy to develop a new service that integrates with other services decreasing development time.

Easy to deploy

Services can easily be deployed to an existing network and scaled up, making setting up own infrastructure obsolete. Connecting own nodes to a network can be done with no effort.


Data storage and communication is encrypted using strong asymmetric encryption.

Respects Privacy

Since las2peer runs on multiple servers, it's hard to track user activity.

Integrated with the Web

Creating RESTful APIs with las2peer as easy as writing Java applications. las2peer integrates services with OpenID and Swagger.
