CAMBRIDGE, United Kingdom, Nov. 26, 2025 /PRNewswire-PRWeb/ -- Today, Collabora Productivity is excited to share the first release of the new Collabora Office for desktop that brings the familiar, powerful Collabora Online experience to run locally on Windows, macOS, and Linux. Open it and feel instantly at home: ODF or DOCX, quick edits or deep dives, a clean, ergonomic interface that helps you get work done without getting in the way.
Collabora Online (COOL) is the company's open-source solution for document editing and collaboration online and at scale. COOL provides a consistent, discoverable user interface (UI) designed with intuitive toolbars and a tabbed interface, which focuses on the tools most people use every day and enables current users to get their work done without clutter.
Today, a first version of the familiar, powerful Collabora Online UI experience enjoyed by over a hundred million downloaders, and that powers businesses, organisations and government bodies across the world, is available to install and run locally as well as online.
"We're excited to bring a first release of Collabora Office to the desktop, letting desktop users work both on-line and off-line in comfort. We look forward to working with and gaining valuable feedback from our partners, customers, users and community. This release provides an opportunity to see the direction of Collabora Productivity's products, and as an open source company, we love to work with others to shape and collaborate on new features."
— Michael Meeks, CEO of Collabora Productivity
What Collabora Office Offers on Desktop
Contemporary office suite:
Collabora Office is a streamlined office suite that includes a word processor and desktop publishing program, spreadsheet application, and presentation program, and drawing application for vector graphics and flow charts.
The suite focuses on offering the workflows that most professionals use every day to create, edit, and collaborate, online and offline. For example, the new Collabora Office chooses streamlined defaults and simpler settings than other open source office suites. (See the new Collabora Office and Collabora Office Classic table for more details, below.)
Great document interoperability:
Being able to open, work on and save different document files is important to users and organisations, which is why Collabora Office supports the OOXML format used by Microsoft Office applications, including Microsoft Word (e.g., DOCX), Microsoft Excel (e.g. XLSX) and Microsoft PowerPoint (e.g. PPTX). As strong advocates for open standards, the new office suite also supports the internationally recognised Open Document Format (ODF), which includes, e.g., ODT for word processing text documents and ODS for spreadsheets.
Privacy by design:
Collabora Office is 100% open source code, guaranteeing no spy-ware. The office suite is offline-first—so no documents need to leave a device unless you choose to share them. Collabora only develops productivity solutions that respects a user's data, their processes, and their digital sovereignty.
Beautiful user interface: Collabora Office uses a consistent and easily discoverable UI with intuitive toolbars and tabbed interface.
Simpler stack: While still based on the LibreOffice core technology, Collabora Office has no Java dependency, which means a cleaner install, smaller footprint and a single, self-contained download.
"Nextcloud has a long-standing, close partnership with Collabora, and we are pleased to have been able to bring our UX engineering expertise to help make Collabora Office more ergonomic and intuitive. This, combined with strong privacy-first design and document interoperability, powers Nextcloud Office as an excellent match for our users and customers' needs."
— Partner Quote: Frank Karlitschek, CEO and Founder of Nextcloud, the popular open source content collaboration platform
The Development of Collabora Office
As the largest single code contributors to the LibreOffice open source project, Collabora Office is based on the project's core technology codebase (in a similar way to how the Linux Kernel is used in many types of Linux), as it provides a vast feature set around interoperable office documents. On top of this, and already implemented in Collabora Online, the suite has a responsive and predictable Web UI built with modern web technologies, such as HTML and JavaScript, Canvas, CSS and WebGL. One of the key drivers for a desktop app is being able to enhance access to key platform functionality that the browser APIs don't handle. Over time this will enable top-of-the-line clipboard use, printing, projecting and, of course, host filesystem support.
"We are delighted to see Collabora bring this functionality from the web to the off-line desktop. Collabora is an essential component of our openDesk suite, and we are pleased to see greater flexibility and mobility for users; it is great to have a consistent experience—whether you need to edit a spreadsheet on a train with no Wi-Fi, or later collaborate with colleagues online."
