Free Alternative to Microsoft Office

LibreOffice is a full-featured, open-source office suite with Writer (Word), Calc (Excel), Impress (PowerPoint), Draw, Base, and Math. The 2026 releases (25.2 branch) brought significant performance improvements for large files, refined dark mode, and a new Ribbon-style interface option that helps users transitioning from Microsoft Office. Developed by The Document Foundation with a global community of contributors, LibreOffice represents the most mature open-source productivity suite available, with decades of development behind it and active ongoing improvements.

Google's free Workspace suite is designed from the ground up for cloud collaboration. In 2026, it remains the alternative of choice for small businesses, startups, and hybrid teams.

With millions of users worldwide and deep integration with Gmail, Calendar, and Drive, Google Workspace has become the default choice for teams that prioritize accessibility and collaboration over feature depth.

OnlyOffice Desktop Editors offer the closest interface and format compatibility to Microsoft Office.

Apple's Pages, Numbers, and Keynote remain free for all Mac users in 2026, though Apple introduced a premium 'Creator Studio' tier ($129/year) for AI-powered features and premium templates.

With decades of refinement, iWork applications leverage Apple's design expertise to create stunning documents with minimal effort, while maintaining compatibility with Microsoft formats for sharing.

FreeOffice by SoftMaker delivers professional-grade office applications with a focus on Microsoft Office compatibility. Unlike many alternatives, FreeOffice defaults to saving in Microsoft formats, making it seamless for users who regularly exchange files with Office users. The suite includes TextMaker (Word), PlanMaker (Excel), and Presentations (PowerPoint).

After a simple free registration, you get a lifetime license with no time limits, feature restrictions, or upgrade pressure. SoftMaker has been developing office software since 1987, and that experience shows in the polish and reliability.

Notion reimagines productivity by combining documents, databases, wikis, and project management into one flexible workspace.

The block-based editing system lets you mix text, images, databases, and embedded content seamlessly.

Particularly popular with students, startups, and knowledge workers, Notion excels at organizing information in ways traditional office suites never imagined. The free personal plan is remarkably generous.

Collabora Online brings the power of LibreOffice to web browsers with real-time collaborative editing. Based on LibreOffice's proven engine, it offers excellent Microsoft Office compatibility while running entirely in your browser.

The Collabora Online Development Edition is free for home users and includes Writer, Calc, and Impress with full collaborative features.

Calligra Suite is an open-source office and graphics suite developed by the KDE community. It takes a more creative approach than traditional office software, with Words for text documents, Sheets for spreadsheets, Stage for presentations, and unique applications like Krita for digital painting and Karbon for vector graphics. While less focused on Microsoft compatibility than LibreOffice, Calligra excels at creative document layouts and artistic work. It's particularly popular among Linux users and those who need integrated creative tools alongside traditional productivity applications.

CryptPad is a privacy-first collaborative office suite where all content is end-to-end encrypted in your browser before reaching the server.

CryptPad offers rich text editing, spreadsheets, presentations, code editing, and even Kanban boards, all with real-time collaboration.

For users concerned about government surveillance, corporate data mining, or security breaches, CryptPad provides genuine peace of mind. The free tier includes 1GB storage, and the entire platform can be self-hosted for maximum control.
