Best Office Suites Software

LibreOffice is a free and open source office suite from The Document Foundation, and its current positioning is unusually pointed: a free and private office suite with no forced AI.

That stance is a deliberate response to where the rest of the category has gone. Every major commercial suite now routes document content through cloud AI services by default, and for organisations handling confidential material the absence of that is a feature rather than a gap. It is also the only suite in this category where the claim can be verified rather than trusted, because the source is public.

The components cover the standard range. Writer handles everything from quick notes to full length books. Calc is a feature rich spreadsheet for analysing data and creating visuals. Base manages databases directly with tables, forms, queries and reports in one place. Math writes formulas through a visual editor or plain text, alongside Impress for presentations and Draw for diagrams.

The project is genuinely community built, with hundreds of contributors worldwide, and translation, documentation and maintenance encouraged in all of the world's languages, which is why LibreOffice reaches languages commercial vendors never localise for. Development is open to new contributors, with The Document Foundation offering an orienting interview before starting. The source is licensed under the Mozilla Public License version 2.0, and the software is free of charge with no licence to buy.

ONLYOFFICE is an office suite built for organisations that want to run their own office environment, combining document editing, collaboration and AI with open source code available on GitHub.

Its most distinctive capability sits in the AI layer. ONLYOFFICE lets you connect any AI model, including a fully local one, and assign different models to different tasks. That is a materially different proposition from every cloud suite, where the AI provider is fixed and document content necessarily leaves your control. A firm that cannot send client material to a third party can still have AI drafting and summarisation.

ONLYOFFICE Docs covers viewing, editing and collaborating on documents, spreadsheets and slides, building and filling PDF forms, reading and editing PDFs with import and export, converting documents to Markdown and HTML, turning textbooks into e-books and navigating diagrams.

Collaboration is granular, with character and paragraph level co-editing modes, document comparison and review, tracked changes, comments and mentions, built in chat or Telegram, and audio and video calls through Jitsi or Rainbow. Security covers three levels of encryption at rest, in transit and end to end, plus secure access and monitoring tools, extra document permissions and support for local AI models, with compliance to international standards. DocSpace organises work into secure rooms. A free tier exists with paid plans quoted per user.

Google Workspace bundles Gmail, Calendar, Docs, Drive and Meet with Gemini AI, built cloud native from the start rather than adapted from desktop software.

That origin still shows in how the products behave. Real time collaboration across devices with everything always up to date is the default rather than a mode you enter, which is why simultaneous editing feels natural in Docs and bolted on almost everywhere else.

The individual capabilities are pitched at concrete business tasks rather than features. Gmail provides custom email at your own domain with branded layouts and mail merge. Calendar offers appointment scheduling through a personal booking page customers use directly. Docs handles eSignature requests for vendor agreements and customer contracts. Drive stores up to 5TB per user on Google's security by design infrastructure. Meet delivers video conferencing with noise cancellation.

Putting eSignature inside Docs is a quietly significant inclusion, since contract signing is normally a separate subscription for most small businesses. Gemini crafts content, generates data insights and conducts research across the suite, and the security layer uses AI to identify and classify sensitive data automatically to minimise loss and meet compliance obligations. Pricing is published openly, from $7 per user per month up to $22, with an entry rate of $3.50 available on introductory terms.

Apple's productivity suite is Pages for documents, Numbers for spreadsheets and Keynote for presentations. Apple no longer markets these under the iWork name, but anyone searching for iWork is looking for these three applications.

They are free on every Apple device and available through iCloud on the web, including for Windows users, which means the entire suite carries no cost for anyone already in the ecosystem. That changes the evaluation considerably, since the comparison is not against a subscription but against whether the apps do what you need.

Their distinguishing characteristic is design rather than feature count. Keynote's animation and transition quality remains ahead of the alternatives, and Pages and Numbers both start from a layout canvas rather than a page of text or an infinite grid, which suits documents where appearance matters and suits dense data work less well. Numbers in particular treats a sheet as a canvas holding multiple tables rather than one enormous grid, which is either exactly right or exactly wrong depending on the task.

All three collaborate in real time across Mac, iPad, iPhone and the web, with changes synced through iCloud, and each imports and exports Microsoft Office formats. Apple Pencil support on iPad allows annotation and drawing directly in documents. The applications are free with no subscription.

Zoho Workplace is an email and collaboration suite presented as a single pane of glass, bringing communication and productivity applications into one platform.

Its competitive framing is blunt and carries a hashtag: disconnected apps, hidden contracts and expensive AI add ons, with the argument that what started as tools to boost productivity has become a system to maximise costs. That lands because it is largely accurate. The major suites have added AI as a per user surcharge on top of an existing per user fee, and the total cost of a productivity stack has risen sharply without the underlying work changing.

The suite covers scalable email, conferencing, calling, voice and team messaging across any device, with unified collaboration giving everyone one space to create, share and manage files, tasks and calendars through document, spreadsheet and presentation editors. Company wide engagement runs through live town halls, forums, live events and peer recognition tools.

Migration is treated seriously, which matters because switching suites is the hardest decision in this category. A one touch tool transfers mail, contacts, calendars and notes from Microsoft 365 or Google Workspace, and split delivery lets part of an organisation move to Zoho while the rest stays with the current provider. That phased path removes the all or nothing risk that stops most migrations before they start. Everything runs on privacy first Zoho infrastructure. Pricing is published on Zoho's own pricing page.

SoftMaker Office is a commercial alternative to Microsoft Office, sold alongside FlexiPDF as an alternative to Acrobat, and the current release is SoftMaker Office Professional 2026.

Its differentiation is achieved by shipping the specific features power users notice are missing elsewhere rather than by matching feature lists. PlanMaker, the spreadsheet, now supports dynamic arrays and XLOOKUP, which are exactly the modern Excel capabilities that make a migration fail when they are absent, since a single unsupported formula breaks an entire workbook.

TextMaker, the word processor, gains the ability to reply to comments, which sounds minor and is not: threaded comment replies are how document review actually works in practice, and a suite without them turns collaborative editing into a chain of disconnected notes. An extra dark variant of dark mode and Markdown support round out the release.

The AI and language tooling is notably practical rather than generative for its own sake. Automatic DeepL translation is built in, which matters because DeepL's output quality is meaningfully better than generic machine translation for European languages, alongside AI based document summarisation and language tools SoftMaker describes as excellent. The company also maintains a font library and offers new free fonts monthly. It is licensed software with prices published on SoftMaker's own price page.

Microsoft 365 combines the Office applications with cloud productivity, security and device management in a single subscription, and the security half is what distinguishes the business tiers from a plain Office licence.

Business Premium is aimed specifically at small and medium organisations up to 300 users, and Microsoft frames it as one comprehensive solution rather than a bundle: everything for administration, billing and round the clock support in one place, reducing cost and complexity. That consolidation argument is the real one for smaller organisations, since a business without a security team cannot meaningfully operate five separate vendor consoles.

The capabilities break into four areas. Collaboration keeps people productive on site or remotely through Teams and the rest of the suite. Access control gives users secure access to business data and applications while ensuring only authorised personnel reach confidential material. Threat protection defends against phishing, ransomware and data loss. Device management covers Windows, Mac, iOS and Android endpoints connecting to company data, keeping them updated.

Including mobile device management matters more than it appears in a feature list. Most small business data leaks through personal phones and laptops rather than through servers, and managing those endpoints is normally a separate purchase entirely. Microsoft publishes security best practice guidance, a digital threats guide and a cybersecurity playbook alongside the product. Pricing is published per user per month on Microsoft's own plan pages.

Apache OpenOffice is a free and open productivity suite maintained under the Apache Software Foundation, covering documents, spreadsheets, presentations, drawings, databases and formulas in one download.

Its most visible strength is reach. The project is presented in more than forty languages, from Asturian and Esperanto through Khmer, Tamil and Armenian, which is a level of localisation no commercial vendor attempts because the audiences are too small to be commercially interesting. For users in those languages it is often the only office suite available at all.

The project is genuinely international, made with help from people all over the world and openly welcoming contribution, with focus areas and native language communities organised separately. Extensions, templates and clipart extend the base installation, and help is provided through community channels rather than a support contract.

Prospective users should understand the project's pace before adopting it. Development is slower than the alternatives, with releases arriving infrequently and each documented through release notes covering bug fixes, improvements and language additions. That is a fair trade for some situations and not for others, and it is the main practical difference between OpenOffice and LibreOffice, which forked from the same codebase and now moves considerably faster. The software is free with no licence to buy, under the Apache licence.

WPS Office from Kingsoft is a free office suite covering documents, spreadsheets, presentations and PDF, built around Microsoft format compatibility and an unusually deep set of AI tools.

Compatibility is the first hurdle any alternative suite has to clear, and WPS states plainly that every file opens smoothly with no formatting issues. That single claim decides adoption for most people, because a suite that reflows a colleague's document is one you use once.

The AI features are more specific than most. Parallel translation handles Word and PDF documents side by side, an AI presentation maker generates and beautifies slide decks from an idea, WPS Writer drafts essays, blogs and letters, and the PDF tools summarise documents and let you hold a conversation with them to extract insights. Photo editing adds quality enhancement and element removal.

The privacy framing is deliberate and worth noting given where the AI features run. WPS states that data is fully encrypted end to end, that it does not share data or work with external parties that might compromise privacy, and that users control their own usage analytics and privacy settings. For a suite whose AI processes document contents, those commitments are the relevant ones to evaluate. A free tier exists, with paid plans at $5.83 per month billed annually at $69.99, and a lower tier at $2.49 per month or $29.99 a year.
