Hub release
Meet the refined Nextcloud Hub!
Optimized for a quick deployment and easy work. Backed by a decade of powering mission-critical setups.
With the Nextcloud Community Conference, we are bringing together contributors, fans, and first-time attendees for two days of talks, workshops, and sharing experiences on 27 and 28 September in Berlin, Germany.
But the event doesn’t stop there! We will continue our ventures during the Nextcloud Contributor Week from 29 September to 2 October with our famous “development sprints”. This is your opportunity to collaborate in person with others Nextcloud members during focused working sessions. From coding to translating or writing documentation, all skill levels come together in this community-driven week to build, improve, and collaborate on Nextcloud improvements in design, functionality, stability, performance and features. It is a unique opportunity for developers to dive deep into the codebase, exchange ideas, and work closely with other Nextclouders.
The atmosphere is vibrant and collaborative, fostering an environment of learning, growth, and innovation. By the end of the week, participants not only have gained invaluable experience but also made significant contributions to the Nextcloud project, helping to shape its future.
Contributor Week at the Nextcloud Community Conference is a celebration of open-source collaboration, fostering a strong sense of community and collective effort. 🫂
We share code, thoughts, inspiration, beer and knowledge, working in areas like:
Nextcloud Include
Diversity strengthens a community, and the Nextcloud Include initiative is our way of helping underrepresented groups get involved in the Nextcloud project. We’re committed to creating an inclusive space where everyone can collaborate and contribute to building world-class open source software.
To support this goal, we offer travel support for the Nextcloud Community Conference, Contributor Week, and other events where volunteer help is needed. Our program covers 80% of travel and hotel expenses in exchange for your support during the event.
Please note: due to limited resources, travel support is only available to a select number of community members. Before applying, consider whether you truly need assistance, as support granted to you may limit help available to someone in greater need.
If you require travel support, please fill out the form linked below.
