My favorite office suite isn't Microsoft 365 or Google Docs — it's free and runs anywhere

If you work on a computer for a living, you've likely accepted the fact that office software is just another subscription you have to keep paying for. Whether it's Microsoft 365 or Google Workspace, good office tools have quietly become synonymous with monthly fees. But that doesn't always have to be the case, especially if you don't use specific features that Microsoft or Google provides.

There are Microsoft subscriptions you can easily replace with free open-source apps, and its office suite is no exception. There are powerful, modern office suites that are completely free, don't need the cloud or a constant internet connection, and run on just about every device you can work on.

The office suite most people overlook

What LibreOffice is and why it's still my first recommendation

LibreOffice is a free, open-source office suite developed and maintained by The Document Foundation. It's not some stripped-down hobbyist project or a half-baked experiment made by a sole developer — it's a full-featured productivity platform that ships with six dedicated applications. You've got Writer for word processing, Calc for spreadsheets, Impress for presentations, Draw for diagrams and vector graphics, Base for database management, Math for building mathematical formulas, and more. That's more tools out of the box than most paid alternatives offer without an upsell.

The suite runs on Windows, macOS, and Linux, supports a massive variety of languages, and costs exactly nothing. No subscription, no free tier with artificial limits, no premium plan. Just software doing what it's supposed to do.

Microsoft Office users won't feel lost

Working with Docx, Xlsx, and Pptx files without major headaches

One of the biggest problems with paid software suites, whether you're doing Office work in Microsoft Office or creative work in Adobe's Creative Cloud, is that they save files in their own proprietary formats, which may or may not work with other programs. That's not the case with Libre Office.

It opens and saves Docx, Xlsx, and Pptx natively, and compatibility only gets better with each release. The current version has put a lot of effort into reducing weird formatting glitches that used to show up when you moved documents across suites.

That said, if you're dealing with heavily formatted corporate documents with complex macros, you might hit a wall now and then. For most everyday documents, reports, spreadsheets, and presentations, it does the job well. LibreOffice's native format is ODF, the Open Document Format, an open standard specifically designed to keep your files future-proof, regardless of what program you end up using in the future.

Your documents stay your business

Why LibreOffice's privacy story is stronger than most cloud-first alternatives

Another major drawback of using commercial office suites like Microsoft or Google's is that they're unnecessarily intrusive. Google Docs requires a Google account, which means you're agreeing to share personal data as part of the deal. Microsoft 365 is steadily adding cloud-based AI into everything, and your documents are increasingly being processed off your machine, whether you want it or not.

Now I'm scared of Microsoft's AI obsession, and if you are too, it's nice to have a program that does what you want it to do without waving half a dozen AI features around in your face. LibreOffice doesn't send any data back, doesn't stream your content to some black box of a model in the cloud, and doesn't need you to sign in before you can start typing. Everything runs locally on your device. For journalists, researchers, or anyone working with sensitive material, that's a fundamental requirement. The fact that it sidesteps the whole surveillance-capitalism ecosystem is a very welcome bonus.

You can put it in the cloud if you want

Self-hosting options that bring collaborative editing to your own infrastructure

Now, installing your word processor on your computer is one thing, but one of the major reasons why Google Docs is so popular is that it's easily available through your browser. LibreOffice has got you covered here, too — the suite also powers browser-based office suites that you can self-host yourself.

Collabora Online, built on LibreOffice technology, lets you deploy a full collaborative editor stack on your own infrastructure. Pair it with something like Nextcloud, and you've got real-time document editing, shared folders, and team workflows without a single document touching anyone else's servers.

If you're already running Docker containers or a small home lab, spinning up a self-hosted office suite starts to feel just another service in your stack. At that point, you're not just replacing Microsoft 365 or Google Docs, you're taking back control of your files, your collaboration, and your long-term access to your own work.

Far from abandoned software

The active development and community keep LibreOffice moving forward

A big point of concern with open-source software is whether it's being maintained or not. LibreOffice is on the opposite end of that spectrum. It ships new major versions on a predictable schedule, almost every six months, with point releases in between to fix bugs and improve compatibility. Recent versions have focused on performance, UI polish, and better handling of big or complex documents, along with a steady stream of new spreadsheet functions and export options.

Behind those releases isn't a trillion-dollar corporation; it's a community of developers, designers, translators, and testers who treat LibreOffice as a long-term project, not a weekend experiment. It might not be flashy, but it's stable, powerful, and clearly built to last.

The price alone makes it worth considering

Why spending nothing can get you almost everything most people need

If your workflow is completely built around real-time collaboration in someone else's ecosystem, you're going to feel some friction when switching to LibreOffice. Sharing a Google Docs link to a client is far easier than walking them through your self-hosted stack, as simple as that might be for you. Complex Excel workbooks with macros might not always translate perfectly, and if your colleagues live inside the Microsoft bubble, you won't magically drag them out with a single LibreOffice install.

But most people don't need all that overhead. They need to write, calculate, and present without renting their tools. And for that, LibreOffice is more than enough, and doesn't cost you your data or money. An office suite is just a set of tools to help you get ideas out of your head and into a document, and LibreOffice does that cleanly, locally, and without forcing an AI tool that you're never going to use.
