LibreOffice

Desktop office software, honestly reviewed. What you actually get when you stop paying Microsoft every month.

TL;DR

• What it is: Free, open-source (GPL-3.0) office suite — word processor, spreadsheet, presentations, vector drawing, database, and formula editor, all in one download [5].
• Who it’s for: Founders, freelancers, and small teams paying for Microsoft 365 or Google Workspace who don’t need real-time collaboration every day, and who want their files to stay on their own machine.
• Cost savings: Microsoft 365 Business Basic runs $6/user/month ($72/year). LibreOffice costs $0 — perpetually, no seat limits, no renewal. A 5-person team saves $360/year minimum, and that’s the cheapest Microsoft tier.
• Key strength: It works. After decades of development, LibreOffice opens and saves .docx, .xlsx, and .pptx files reliably enough that the person on the other end usually won’t notice you’re not running Word [5].
• Key weakness: No built-in real-time collaboration. If your workflow depends on multiple people editing the same document simultaneously — the way Google Docs works — LibreOffice’s desktop version doesn’t solve that problem. You need Collabora Online layered on top, which is a meaningful additional setup step [5].

What is LibreOffice

LibreOffice is a full office suite maintained by The Document Foundation, a non-profit that forked it from OpenOffice.org in 2010 when Oracle’s acquisition of Sun Microsystems left the project’s future uncertain. It’s been under active, independent development ever since.

The suite ships six applications: Writer (word processor), Calc (spreadsheet), Impress (presentations), Draw (vector diagrams and flowcharts), Base (database front-end), and Math (formula editor). The current release as of this review is LibreOffice 26.2, which added Markdown support in Writer, Connectors in Calc, and spreadsheet performance improvements [website].

LibreOffice’s native format is ODF (Open Document Format), an ISO standard. It reads and writes Microsoft Office formats — .doc, .docx, .xls, .xlsx, .ppt, .pptx — as first-class citizens, not as an afterthought. Germany’s federal government recently made ODF mandatory as the standard format across its entire sovereign digital infrastructure, encoded in the Deutschland-Stack framework that governs public administration at every level [website blog]. That’s not a small signal for a format’s staying power.

The GitHub repository is a read-only mirror of an upstream Gerrit codebase. The project has 3,758 GitHub stars, which dramatically understates its actual adoption — LibreOffice is pre-installed on most Linux distributions and has hundreds of millions of users globally.

Why people choose it over Microsoft 365 and Google Workspace

The reviews are thin on third-party coverage — most people who use LibreOffice have been using it for years and stopped writing about it because it just works [5]. That’s a signal in itself.

The cost and ownership argument. This is the dominant reason people switch. Microsoft 365 is a recurring bill that only increases. LibreOffice is a one-time download with no expiration date, no seat counting, no price increases, and no licensing compliance overhead. One reviewer at Hyperborea.org, who has been using it across Linux, Windows, and macOS for decades, puts it plainly: “It doesn’t get in my way with nagware, or making sure I have enough licenses for all the family’s computers, or trying to monetize my data or convince me to move files to a cloud service.” [5]

Privacy and offline-first operation. With cloud office suites, your documents transit a vendor’s infrastructure every time you save or open a file. With LibreOffice, the file lives where you put it. For founders handling contracts, financial models, or anything confidential, that matters. There’s no question about whether Microsoft or Google is training models on your content [5].

Microsoft format compatibility has genuinely improved. There was a time when sending a .docx edited in LibreOffice was a formatting gamble. That era is largely over. The same Hyperborea reviewer notes: “There are probably a few Word and Excel features they don’t support, but none that I’ve noticed for a long time.” Complex documents with heavy tracked changes, intricate Excel macros, or elaborate PowerPoint animations can still have issues — but for the vast majority of business documents, interoperability is a non-problem [5].

The ODF mandate momentum. Germany’s decision to mandate ODF across federal, state, and local government is the kind of institutional signal that tends to accelerate adoption. Public institutions using ODF need office software that handles it natively — and LibreOffice does [website blog].

Features: what it actually does

Writer is a full-featured word processor with styles, templates, tracked changes, comments, mail merge, a table of contents generator, and cross-references. LibreOffice 26.2 added Markdown export, which is useful for anyone writing documentation that ends up in a Git repository [website].

Calc handles spreadsheets with pivot tables, conditional formatting, goal seek, solver, macros, and 500+ functions. Version 26.2 improved performance for large spreadsheets, and added Connectors for importing external data sources [website].

Impress is the presentation application. It supports custom animations, slide transitions, presenter view, and the standard Master Slide workflow. It opens .pptx files and exports to PDF or as a standalone slideshow [website][4].

Draw handles vector graphics and flowcharts. It supports layers, 3D objects, connectors between shapes for diagrams, and exports to SVG and PDF. It’s not Illustrator, but it handles org charts, flowcharts, and technical diagrams without requiring a separate application [4].

Base connects to databases via JDBC or ODBC and provides a form and report interface. It’s the weakest application in the suite — Access was already a niche product and Base fills that same niche without quite matching Access’s macro capabilities.

Extensions and templates: The Document Foundation maintains an extensions repository. Extensions cover additional dictionaries, macros, file format support, and integrations. The review process for extensions has been community-maintained since the project’s early days [3].

Mobile and online: The core desktop suite does not have a native mobile editing application. There is an Android viewer, but it’s read-only. The practical mobile editing option is Collabora Office, built on LibreOffice, which runs on Android and iOS and integrates with Nextcloud and Dropbox for seamless file access [5]. For browser-based collaborative editing, Collabora Online (with a free self-hosted developer edition called CODE) and Nextcloud Office (which combines Collabora with Nextcloud) are the two main paths [5]. The Document Foundation announced in early 2026 that it is reopening work on its own self-hostable online version — worth watching but not yet a solved product [5].

Pricing: the math against Microsoft and Google

LibreOffice: $0. Download, install, use indefinitely. No seat limit, no renewal, no enterprise licensing negotiation. Available free from the website for Windows, macOS, and Linux. Also available on the Microsoft Store and Apple App Store for a nominal fee (the fee funds development; the download from libreoffice.org is free) [5][website].

Microsoft 365 for comparison:

• Personal: $69.99/year ($5.83/mo) — 1 user
• Family: $99.99/year ($8.33/mo) — up to 6 users
• Business Basic: $6/user/month — web and mobile apps only, no desktop installs
• Business Standard: $12.50/user/month — includes desktop Office apps and Teams

A 5-person team on Microsoft 365 Business Standard: $750/year. On LibreOffice: $0. Over three years: $2,250 saved, plus whatever your time is worth not managing license renewals.

Google Workspace for comparison:

• Business Starter: $6/user/month
• Business Standard: $12/user/month

Same 5-person team on Google Workspace Business Starter: $360/year.

Where the math gets complicated: LibreOffice doesn’t include cloud storage, video conferencing, or email hosting — things Microsoft 365 and Google Workspace bundle. If you’re switching from Microsoft 365 to LibreOffice and you still need email, you’ll pay separately for email hosting. Factor that in before declaring a $750/year victory.

Collabora Online CODE (self-hosted browser editing): free for self-hosting, requires a server (a $10–20/mo VPS works). Collabora’s commercial license for larger deployments is priced separately. If you already run Nextcloud, Nextcloud Office is the smoothest path and adds browser-based collaborative editing on top of the free LibreOffice format compatibility.

Deployment reality check

Desktop install: straightforward. Download the installer from libreoffice.org, run it, done. Package managers on Linux handle it automatically. Most users will be editing documents within 10 minutes of deciding to try it.

Where it gets harder: if you need collaborative editing — multiple people working on the same document at the same time — you’re not done at the desktop install. You need either:

1. A file sync service (Nextcloud, Dropbox, Syncthing) combined with a convention that only one person edits at a time and saves before the next person opens the file — workable but fragile.
2. Collabora Online CODE self-hosted — a Docker deployment, a domain, and a reverse proxy. Realistic time estimate for someone comfortable with Docker: 2–3 hours to a working instance. For someone new to server management: a full day plus a guide.
3. Nextcloud Office — the most complete self-hosted solution, but now you’re deploying and maintaining Nextcloud as well.

Known friction points from real usage:

• Dark mode on Linux does not work reliably. One reviewer describes being unable to get a dark document in a dark window simultaneously — getting combinations of light-on-dark and dark-on-light but not full consistency [5]. This is a years-old complaint that has not been cleanly resolved.
• Complex Excel macros (VBA) won’t run in LibreOffice. LibreOffice Basic is the macro language, and while simple macros often translate, anything using Windows-specific APIs or complex Excel objects will need rewriting.
• Intricate PowerPoint animations sometimes render differently in Impress.
• Spell-check and grammar features are less sophisticated than Word’s editor, which now integrates Microsoft Editor with AI suggestions.

Pros and cons

Pros

• Completely free, no subscription. $0 perpetually. No renewal emails, no seat audits, no vendor lock-in on pricing [website][5].
• GPL-3.0 licensed. You can modify it, redistribute it, or deploy it internally with no license agreements. True software ownership [website].
• Privacy by default. Files stay local. No content transits a vendor’s infrastructure unless you put it there [5].
• Microsoft format compatibility has matured. .docx, .xlsx, .pptx round-trip reliably for standard business documents [5].
• Full-featured suite in one download. Word processing, spreadsheets, presentations, diagrams, database front-end, formula editor — covered [website][4].
• Cross-platform. Windows, macOS, Linux. Same features, same files, same experience across all three [5].
• Institutional momentum. Germany’s ODF mandate is a meaningful signal that sovereign digital infrastructure is moving toward LibreOffice-compatible formats [website blog].
• Active development. LibreOffice 26.2 shipped in early 2026 with meaningful performance and feature improvements — not a stagnant project [website].

Cons

• No built-in real-time collaboration. This is a hard constraint. If your team needs simultaneous multi-author editing, LibreOffice desktop doesn’t provide it. Workarounds exist (Collabora Online, Nextcloud Office) but they require additional setup and infrastructure [5].
• Mobile editing is absent from the core product. The Android viewer is read-only. Collabora Office fills the mobile gap, but it’s a separate product [5].
• Dark mode on Linux is broken. A minor issue for some, a daily irritation for others — and it has been broken for a long time [5].
• VBA macros don’t transfer. If your business relies on complex Excel VBA automation, migrating to LibreOffice requires rewriting those macros in LibreOffice Basic or Python.
• Collabora Online / CODE is not a Google Docs replacement. The reviewer at Hyperborea notes: “Neither works as easily as Google Docs when it comes to multiple authors, comments, and sharing permissions” [5]. The collaborative experience requires more memory on the self-hosted server and more configuration than Google Docs takes to use.
• No AI writing assistant in the core product. Microsoft 365 Copilot and Google Workspace Gemini have deeply integrated AI writing tools. LibreOffice has no equivalent built in. Extensions exist, but they’re third-party and unpolished compared to Microsoft’s and Google’s native integrations.
• Third-party review coverage is thin. This is itself a signal — people aren’t writing about LibreOffice in 2026 because it’s not new and exciting, it’s stable and boring. That’s good for reliability but means fewer community resources for troubleshooting edge cases.

Who should use this / who shouldn’t

Use LibreOffice if:

• You’re a solo founder or freelancer paying for Microsoft 365 Personal or Family and 90% of your time is spent in documents you write alone.
• You handle sensitive documents — contracts, financials, client data — and you want them on your machine, not transiting a vendor’s servers.
• You’re a small team (2–5 people) where real-time simultaneous editing is occasional rather than constant, and you can share files via Dropbox or a simple file server.
• You already run Nextcloud and want to add browser-based document editing without paying for Google Workspace.
• You’re on Linux and want a full office suite that integrates with your distribution’s package manager.

Consider the tradeoffs carefully if:

• Your team edits shared documents simultaneously every day. You’ll need Collabora Online or Nextcloud Office, which adds setup complexity and infrastructure cost.
• Your business depends on complex VBA macros in Excel. Migration is possible but requires development work.
• You’re buying into an AI writing assistant as a core productivity tool. LibreOffice doesn’t have a native one.

Stay on Google Workspace if:

• Your team is distributed and collaborative editing is the primary daily workflow. Google Docs is simply better at this, and at $6/user/month for Business Starter, it’s cheap enough that the productivity trade-off doesn’t make sense.

Stay on Microsoft 365 if:

• You’re in a Windows-heavy environment with heavy Excel automation, Teams integration, or SharePoint dependencies. The switching cost in macro rewrites and workflow changes would likely exceed years of subscription savings.

Alternatives worth considering

• Collabora Online — the server-side, browser-based version of LibreOffice. The Developer Edition (CODE) is free to self-host and gives you Google Docs-style collaborative editing with LibreOffice’s format compatibility. Requires Docker and a VPS. The commercial version is for larger deployments.
• Nextcloud + Nextcloud Office — if you’re already running or evaluating Nextcloud for file storage, Nextcloud Office layers Collabora on top and gives you a more integrated experience. More setup than just LibreOffice desktop, but closer to a full Google Workspace self-hosted replacement.
• ONLYOFFICE Docs — another open-source office suite, more focused on collaborative editing out of the box. Better real-time collaboration story than base LibreOffice, though it’s a separate product from its document editing core [1].
• Google Workspace — the obvious paid alternative. Better collaboration, worse privacy, recurring cost. Honest choice for teams where simultaneous editing is the daily workflow.
• OnlyOffice DocSpace — room-based collaboration with built-in document editors. Competitive with Google Workspace for teams that want self-hosting options [1].
• Cryptpad — end-to-end encrypted collaborative document editing for teams where privacy is the primary constraint.

For a non-technical founder choosing between LibreOffice and Google Workspace: the question is whether your team edits documents together at the same time or takes turns. If it’s turns, LibreOffice saves money. If it’s simultaneous, Google Workspace is the more practical tool unless you’re willing to self-host Collabora.

---

Bottom line

LibreOffice is the office suite that has quietly outlasted multiple generations of competitors because it does one thing well: lets you create and edit documents without asking permission or charging a subscription. For solo founders and small teams whose document workflow is primarily individual — one person writes the contract, sends the PDF, done — there is no coherent reason to pay $750/year to Microsoft or Google for something LibreOffice provides for free. The format compatibility questions that plagued early LibreOffice are mostly resolved. What remains genuinely unsolved is real-time collaborative editing, where Google Docs still leads comfortably and where Collabora Online is the self-hosted answer if you’re willing to maintain a server.

The Germany ODF mandate is worth taking seriously as a long-term signal: sovereign digital infrastructure is moving toward open formats, which means LibreOffice compatibility is becoming a requirement rather than a nicety for anyone working with government entities. For founders in that space, the switching argument gets stronger every year.
