About


About Caroster 
Caroster was born out of a personal need (as many projects are). Its aim is to address the organizational challenges of arranging carpools for members of sports associations attending practices, tournaments, and competitions. The founder, Xavier, needed a simple and efficient solution to organize carpooling for his association. The result was Caroster, the Doodle of carpooling. 
What started as a personal idea became reality in 2020 and grew gradually, spreading by word of mouth without formal marketing. The attraction was such that Caroster now, in 2024, reaches up to 1000 events created per month. 
As the project evolved, so did its mission: to facilitate mobility for events through easy carpooling, aiming to reduce environmental impact and make shared transportation accessible. 
Caroster is developed and hosted by Octree, a non-profit studio creating digitals solution for the social and ecological transition. The project aligns with Octree’s vision to contribute to creating digital commons. By complementing public transportation networks, Caroster aims to shape the mobility landscape of the future. 

Get involved in the Caroster community 
Without its community, Caroster wouldn’t be where it is today. The Caroster community is essential to the platform’s success and growth. Whether you're a user, developer, researcher, or mobility expert, your involvement drives meaningful progress in shared mobility. Caroster encourages collaboration across different fields, enabling us to innovate and expand our shared platform in ways that benefit everyone. By contributing to Caroster, you're helping to shape a future where carpooling is easy, accessible, and sustainable for communities everywhere. 
Community members are invited to share their experiences, contribute feedback, develop new features, and support each other. Through open collaboration, we aim to create an accessible, eco-friendly future for shared mobility. 

What is a digital common? 
A digital common is a shared, collaboratively created, and managed digital resource. This includes open-source software, databases, and freely accessible content, such as geographic data from OpenStreetMap or articles from Wikipedia. These resources are governed by common rules to ensure their accessibility and collective use, empowering everyone to contribute and benefit.
