The big Tech companies are dominating every aspect of our lives and work, and we’re all getting tired of it. Their power is a threat to privacy, and, on a bigger scale, democracy and the sovereignty of entire countries. And for businesses, there is a real risk to resilience, compliance and security.
The result is that individuals and organizations are looking to take back ownership of their data. Digital sovereignty is becoming a priority. We see a strong momentum, for example in France, Austria and the Netherlands. Change is coming!
At Nextcloud, we are happy to provide the means. As you are reading this, Nextcloud is running on over 500,000 servers, some of which have millions of users. Every year, millions of new people see Nextcloud power their digital workplace, giving them control over their data. With every release, we are pushing to give you more control while removing the barriers to transparent and open technology.
With Nextcloud Hub 26 Winter, we deliver improvements to data portability and cross-organization collaboration features. We harden Nextcloud’s security and improve performance across the board. And of course, our designers and engineers have been busy researching and fine-tuning file sharing, email, chats, meetings, and everything you deal with on a daily basis.
Introducing the new Nextcloud Hub 26 Winter, your platform for digital freedom.
Nextcloud Hub 26 Winter is the result of the combined community effort of thousands of brilliant and motivated developers, testers, translators, writers, and designers. They collaborate around a vision of privacy, control and freedom as private individuals, team members at the Nextcloud company or contributors at hundreds of enterprises, universities, service providers and a wide variety of public entities.
It is this ecosystem that is the real strength of Nextcloud, allowing the open source community to challenge big tech head on. We truly stand on the shoulders of giants. Thank you, everybody, for your amazing help!
Every new digital work place, ever users’ document, chat or video that is kept private and secure is the result of your hard work, so we celebrate this release together with all of you!
What does it mean to own your data? It’s when you decide where and how to store, move, and collaborate on it. We give you more ways to work together online while staying in control of your data.
Control always means choice. With Nextcloud Hub, nobody locks you into a cloud to control you and extract more money, holding your data, tools or privacy hostage. You decide where your data is: on your company’s server, with a provider you trust, or maybe at home, on your Raspberry Pi.
When you are in control, you can move your own data, such as files, tasks, or users, out and in. Nextcloud is built on open standards, which makes it strong at interoperability and migration. With Nextcloud Hub 26 Winter, we improve the user migration, which allows you to move your data to another server:
And migrating your whole Nextcloud server is easy too. Read more about backup and migration in the Maintenance section of our documentation.
Nextcloud is fundamentally decentralized, which means powerful collaboration even across servers. This is called Federation. While you can’t send chat messages between closed platforms like Facebook Chat and Telegram, you can send an email from Gmail to Hotmail and then to your work mailbox: that’s federation in practice.
Federation lets you collaborate across Nextcloud Hub servers with a single account. For example, invite a person from another organization to a chat or a call from their instance. Or share a file to their Federated Cloud ID, and it pops in their file system just like any other share.
We are expanding federated features in Nextcloud Hub. Now you can share Nextcloud Deck boards with people from the outside to let them browse, add cards, or create stacks. With calendar federation, you can track events in shared calendars for cross-team planning.
Another app that now supports federation is Nextcloud Teams. It lets people create own groups to streamline group sharing across apps and have easy access to all shared resources. Now you can create teams with people from different Nextcloud Hubs.
For extra security in collaboration across servers, file locking now also works in federated sharing.
Join us on February 25, 2026, 3 PM CET, for a live demo of Nextcloud Hub 26 Winter and Q&A with our team.

Sign upNextcloud Hub is designed for environments where security and compliance matter. That’s why it’s already powering thousands of critical setups with strict compliance frameworks. And at home, where your family photos don’t require a complete security policy, Nextcloud keeps your data away from the prying eyes of Big Tech. Enterprise-grade protection is now accessible to all.
With this release, we updated security features useful for both private setups and organizations.
Keeping your files encrypted now takes less effort with more options in the browser:
Please keep in mind that working with encrypted files in the browser is always less secure than via your local client.
The Confidential Files feature can automatically assign classification labels to files based on properties and metadata. This helps automate access restrictions or set up automations in Nextcloud Flow. With this release, security labels are automatically readjusted when document properties change.
We added a setting to restrict external invites in Nextcloud Calendar to protect you from potential security risks. When the restriction is enabled, people will only be able to invite other Nextcloud users.
One of our goals at Nextcloud is to break the myth that secure, open source tools are intimidating and complex. We bring all you need in one place, automate what shouldn’t need thinking about, and give you low-friction, human-centric design. While having more control, with Nextcloud Hub 26 Winter you get more done with less effort.
We introduce multiple features for your day-to-day chat interactions. First, you can pin messages to keep group announcements, reminders, links, and files visible. You can configure the time period to automatically unpin the message later, as well as browse all the pinned messages in the sidebar menu.
Schedule messages to be sent later to head into your evenings and holidays with a clear head. Quick time presets are there for your convenience.
Optionally split the message bubbles and display your messages on the right, similar to other popular chat apps.
You can now use live transcription with translation, bridging the language gaps for international teams. Transcriptions are powered by AI, which is completely optional.
You can now configure audio options for your calls as opt-in settings:
And finally, background blur in video meetings is now more efficient and accurate with hardware acceleration.
Attachments are now immediately visible in your threads, so there’s no need to scroll through all your messages to find documents.
You can enable automatic tentative appointments from emails in Nextcloud Calendar. When this setting is on, all meeting invitations you receive via email will appear in your calendar, so you can accept or decline them.
For conversations you absolutely don’t want to miss, mark a thread you want to follow as a favorite to pin it to the top of your inbox.
Turn off message previews and browse more emails at once in a compact mailbox with “Compact mode”.
We improved the UI of advanced filters by polishing the design, improving wording, and expanding some of its features. Quick filters have also been improved: you can now filter out unread emails, emails with attachments, and emails addressed to you quickly from the top of your inbox.
The smallest details matter when you work with multiple versions of important files. Think contracts, agreements, or policies. By popular demand, we introduced two ways to compare documents. The feature also lets you select another file from Nextcloud or the local disk to compare with your current file.
Browse the content of both files right in front of you with all changes highlighted in text and tracked on the left margin.
Nextcloud Office uses the Manage Changes mode to compare differences in one file, which you can navigate, accept, or decline.
You can now read and resolve comments more easily. We improved comment cards, adding a quick editing icon and polishing the design.
You can now access Nextcloud Office settings quickly, via Options menu in the Files tab.
Activate Sheet View to filter data independently from other collaborators in your spreadsheet. This greatly reduces interruptions when many people need to access the same data in large data sets.
The new Table Design tab lets you adjust the appearance of your tables in XLSX files using banded rows or columns, and also access style presets quickly. If you open a Microsoft file with a styled table, Nextcloud Office can recognize it and let you switch to another style.
Sometimes you don’t have access to a a big screen or projector to run a slideshow, or maybe your screenshare does not perform well with a slow connection.
With the “Present to All” feature, you can present to everyone online. People in the document follow you automatically as you switch between the slides.
For example, you can share a presentation file in a Nextcloud Talk call, ask people to open the file and follow the presenter, then run a presentation without the need for a screen share. And everyone can also go back to check anything they missed.
Working with scientific formulas? You can now use LaTeX formatting in Nextcloud Text: type formulas directly in the text, and they will be converted to nicely formatted equations.
Some of us deal with unstable networks pretty often, especially during travel. In Nextcloud Hub 26 Winter, we made Nextcloud Text and Collectives more robust in the face of a weak internet connection.
On devices with limited screen height, toolbars automatically collapse to give you more space. Support for iOS VoiceOver assists screen reader users on iOS when enabled in Nextcloud Office admin settings.
We are expanding the tools available to you in Nextcloud Whiteboard so you can run more interactive, immersive sessions while staying organized, even with many participants.
Set global timers for group tasks to make sure everyone stays on schedule.
Add voting to conduct polls or make team decisions, and then render the results for everyone on the whiteboard.
People can add emoji reactions to respond to ideas on the whiteboard and interact with elements.
Use comments to leave contextual feedback on any sketch, diagram, or text. Ask questions or have focused discussions among the team.
You can create and insert tables in your Whiteboards to structure information easily, without the need to link outside sources.
Recovering lost data is now easier. Whiteboards now support version history, just like other files in Nextcloud Hub.
Nextcloud Hub features the first open source AI assistant that doesn’t prey on your data. We continue improving our AI tools to ensure compliance, performance, and usability.
When you don’t provide your team with AI you can trust, people start using third-party services like ChatGPT for work. This quickly becomes a problem: legally, technically, and ethically. Nextcloud Assistant is the industry-first open-source AI assistant that you fully control and choose where and how to run it. Our Ethical AI rating helps you pick and configure models to ensure privacy and control with the features you need. And of course, AI in Nextcloud is completely optional.
We think it is important to let you know when you deal with AI-generated content. With this release, we let you clearly label AI content: images, documents, and audio. This labeling also aligns with the EU AI Act.
We gave Nextcloud Assistant a better memory. It can now remember what you talked about across all your chats, so you don’t need to give it a briefing again to come back to a topic. If you prefer, you can configure and remove these memories.
We greatly improved the performance of all locally running AI components, resulting in up to 10s faster results in text and image generation, speech-to-text and text-to-speech conversion, translation, agent tools, and more.
We want to offer you choice and always expand supported models and features. We added support for Olmo 3 and self-hosted IBM watsonx, and also improved other AI integrations, such as Recognize and OpenAI.
We know that not every team works the same way. Some need to work offline, from airplanes and railroads. Some need close collaboration during the day, running workshops or brainstorming sessions. That gives us a big range of hardware, devices, and conditions to prepare Nextcloud Hub for. So our other important focus is always the performance of our apps and the platform the Nextcloud ecosystem is built on.
Nextcloud supports all these powerful features in your sovereign, private cloud. To make sure we keep things running fast, we did a significant rewrite of Nextcloud’s advanced file access layer with parts in PHP, Rust, and Go.
The new ADA engine computes permissions and access in advance and prioritizes direct access to data. ADA stands for Accelerated Direct Access and is also our homage to Ada Lovelace, an English mathematician and writer often considered the first computer programmer.
With the rewrite, we introduced significant changes to our database and file system to support deployment on a large scale:
Read more about the new architecture in a dedicated blog post.
A lot of recent work focuses on reducing unnecessary load and latency in everyday interactions:
We do like side quests. But most of our work is under the hood to ensure stability and hardening of existing tools. In Nextcloud Hub 26 Winter, as many as 98.5% of all pull requests were maintenance work.
In the Nextcloud Server repo, there are 1904 maintenance-related pull requests vs 29 features. It’s 913 vs 29 in Nextcloud Groupware, 597 vs 11 in Nextcloud Talk, and 1328 vs 17 in Nextcloud Office.
The Nextcloud ecosystem is built on open standards and clear guidelines. For users, this provides flexibility to build Nextcloud Hub into any ecosystem and delivers a unified, reliable experience across all the applications. For developers, this means stable APIs, a clear app framework, and predictable interfaces.
Key API updates in Nextcloud Hub 26 Winter include:
OCA.Files.SidebarTo keep your apps compatible with the new version of the Nextcloud platform, please carefully read the updates in our documentation.
With 400+ applications available in the Nextcloud App Store, you can extend your setup far beyond the core tools. Here are some new and rising apps developed by our community:
Build applications for Nextcloud in any programming language using our complete API documentation and a growing library of ready tutorials. What’s more, you can subscribe to a dedicated developer newsletter and get all the relevant updates delivered to you.
And our developer hub also comes in a fresh design!
Nextcloud Hub works across devices in a browser or via apps that give you more flexibility, security, and device-specific features.
On macOS, the Nextcloud app can work as a classic Finder extension or run a Virtual File System (VFS) to make file sync truly seamless. Before, we had clients with and without VFS. And now it’s one app, and you choose the mode that fits.
The VFS on Windows was improved, too. It can now use the on-demand sync mode, like the macOS client, to reduce unnecessary load and make sure only the relevant files and folders are synced.
We made a range of other changes to our desktop clients:
notify_push useWe worked in great detail on our mobile clients for iOS and Android, polishing buttons, menus, and search, as well as improved performance of file sync and AI tools.
What’s new:
Download the latest version of our apps now for a new and improved feel:
We make it easier to log in to your Nextcloud account with a mobile device: Open your account menu at the top, click the icon, scan the code from the Nextcloud Talk or Files app on your phone, and you are connected!
First our tools, then our data, finally — our decisions? There’s hardly an aspect of our life and work that hasn’t been commodified, but it’s not too late to get control back. With Nextcloud Hub, you collaborate with full ownership. That just feels great.
It’s time to experience this new feeling of control yourself. Get started with Nextcloud Hub 26 Winter today!
*The Nextcloud Enterprise version of Nextcloud Hub 26 Winter will become available soon, once we successfully run the additional testing and complete certification.
For new Nextcloud All-in-One (AIO) users, you can install Nextcloud Hub 26 Winter directly by checking the “Install Nextcloud 33” box. For active AIO users, we have a dedicated setup guide. Follow the guidelines to easily set up Nextcloud Hub 26 Winter.
