ONLYOFFICE Docs

Pros: I was just looking for a simple, free Word alternative for my college work. Tried a few options like WPS Office, LibreOffice, and Google Docs. Some had weird layouts, others had annoying ads or limited offline support. That’s when I found ONLYOFFICE.

At first glance, the interface felt super familiar — like MS Office 2016-style. It didn’t feel like I was compromising on quality just because it was free. No popups, no ads, just a clean workspace.

Cons: What bothered me most, though, is how little help there is online. Got stuck trying to format something? Good luck finding a proper tutorial — especially one that’s simple or in Hindi. It’s not a huge deal if you’re tech-savvy, but for someone new, it can be frustrating figuring things out on your own.

Overall: but not everyone wants to spend money on it, especially for basic work. I discovered ONLYOFFICE over a year ago, and surprisingly, it’s been my go-to ever since. No ads, clean UI, and honestly, it feels like a proper Microsoft Office twin — but for free.

Pros: The Document and Spreadsheet of OnlyOffice Doc (OOD) provides what I need. OOD is quite compatible to MS Office. As a long term MS Office user, OOD is not strange to me. It is free for individuals who will not be bothered if their computer/system disk is broken because I am one of the victims using retailed licenses. To open all MS Office files are the same operations without hassle.

Cons: There is no way to provide feedback to you/developer. I have written to the forum to express my problems I encountered but haven't had replied but the ai robot. If there are frozen row or column, the cursor is always at the beginning of the file but not the last record. Bookmark doesn't automatically look up the text you print in the box of the window. You need to move the right hand scroll bar to look for it. For spreadsheet, data (colored texts and/or numbers) are sometimes automatically changed into a mess of blurred color objects if it is not used for a period of time. It is required to be closed and re-opened again.

Overall: I am retired but leaving number of MS Office files in my own computer. With a sudden broken system disk, I could easily open all my files without hassle or waste of time to ask MS support for help. I found that OOD is good for me for handling daily records. I used it just over a month. I cannot tell too much about Pros because it is almost similar to MS Office except some functions that I have never used during my working life. For those Cons, I believe the developer will gradually sort them out.

Pros: The best thing about ONLYOFFICE, in my opinion, is that it's free to use. I initially started with Microsoft Office on Windows, but the free version is full of advertisements—especially in the extensions. In contrast, ONLYOFFICE has no ads in its extensions, which I think is the best part. It’s completely free .

Especially after the version 9 update, it looks almost exactly like Microsoft Office. It doesn’t feel out of place—it actually looks like a native Microsoft app, unlike many other free alternatives.

Cons: As for the cons, I think it needs better cloud integration. And of course, it could use more extensions. While there are already some useful ones, I believe having more would be great. Another issue is the lack of tutorials online. The software itself is excellent, but it’s really hard to find tutorials for it. They should definitely focus on creating more tutorial videos so people can learn to use it more effectively.

Overall: Onlyoffice is a solid free alternative to Microsoft Office. It looks clean, has no ads, and comes with useful templates. I’ve been using it for over a year and really like it. It could use better cloud support and more tutorials, but overall, it’s a great free option.

Pros: Useful for collabration work by a team.
Similar to MS Word functionality in general
Cheaper than MS
Good across multiple Android devices

Cons: Formatting is not as good as MS Word
Less commonly use compare to MS products

Overall: Useful as a simple document processing tool
Helpful when use together with AI in Google cloud
Intend to use this for collaboration work

Pros: I prefer open-ended software over closed software when it gets as good or better than the alternative competitors.

Cons: Because I've been trained and used at least two of the main primary competitors for so long, I have to intentionally spend more time with the plethora of detailed customizable options available with this suite.

Overall: Over the last year or two, OpenOffice has become as effective and comparable to popular mainstream office editing software. I'm usually a person who is a first adopter of software and share what I think with others. Wish more people knew how great this is nowadays, highly recommend anyone checking it out for themselves to see what works best for them, you can only benefit from exploring this product!

Pros: My favorite thing about OnlyOffice is the new look after the version 9 update — it’s actually pretty cool. I also really like the AI features. It’s great that you can choose different AI LLMs; for example, I use Together AI for image creation, Gemini for translation, and others for general purposes. That flexibility is really nice.

A few years ago, when I first joined the Linux community, I started using OnlyOffice. To be honest, the interface felt familiar right away — so yeah, that’s a plus.

Cons: I don’t have many complaints, but of course, there are a few things that could be improved. For example, I think we need more templates — especially creative ones. If there were an option to generate custom AI-based templates, that would be amazing. Also, while cloud services are already supported, I think the integration could be improved further.

Overall: OnlyOffice has come a long way. The new look is great, and the AI features are a nice touch. It’s easy to use and familiar, especially for Linux users like me. A few more templates and better cloud support would be nice, but overall, I’m pretty happy with it.

Pros: Everything about this program is amazing! I love how feature-rich it is and how attentive the developers are to the needs of those who use it. The online version is incredible as well.

Cons: Can't really think of any cons. I guess the devs could do a little more testing of certain things before they roll them out (I'm thinking of when they said OnlyOffice was now compatible with .pages, .numbers, and .keynote files but the compatibility wasn't very good).

Overall: Overall great experience. I've really enjoyed using OnlyOffice and I'm so grateful it exists. It made switching to Linux a lot easier for me since I was able to learn the program on my previous computer beforehand.

Pros: OnlyOffice is the perfect solution for those that want to collaborate and don't like Google Docs or Microsoft Office. My favorite feature is the built-in PDF editor. This is a game changer for companies that don't want to sell out for the expensive Adobe Acrobat Pro.

Cons: The only issue we ever had with switching from Microsoft to OnlyOffice was the inability for the spreadsheet program to import values from networked xlsx files that have spaces in the directory string. We have to rename all of our files to get it to work properly and remove any spaces with the file names.

Overall: I recommend OnlyOffice to everyone. Its the only option for those that want a fully featured office suite for collaboration on the web, desktop and mobile.

Pros: I got to know this software after some issues with payments and licenses but this is great and free. I don't need to pay every month for something I NEED to use. It's also light to the pc, making it a great choice for office equipment that is rather old or cheap

Cons: It took me some time to get used to the main menu and how to create a new document.

Overall: I feel great, now I get to work my office papers without having to pay massive amounts of money every single month and having to take that as a monetary loss

Pros: Excellent compatibility with Microsoft Office formats (.docx, .xlsx, .pptx)

Modern, intuitive, and user-friendly interface

Smooth real-time collaboration features

Self-hosting option with great control over privacy

Integrations with services like Nextcloud, ownCloud, Seafile, etc.

Cons: Some advanced features (like macros) are not fully supported yet

Performance can lag slightly with very large or graphic-heavy documents

The mobile version, while functional, is more limited compared to the desktop version

Overall: ONLYOFFICE has pleasantly surprised me as an office suite solution. It offers a clean, modern interface very similar to Microsoft Office, which makes the transition easy. Its compatibility with Word, Excel, and PowerPoint documents is excellent, even for complex formats. I use it both in collaborative and individual settings, and its performance has been stable and reliable.

One of its greatest strengths is real-time collaboration, which has significantly improved our team’s productivity. I also really appreciate its easy integration with platforms like Nextcloud, making it a flexible solution for self-hosted environments. Overall, it's a very complete and highly recommended option.

Pros: Very good alternative to Microsoft 365.
I wrote my PhD manuscrit and presentation initially in Word and PowerPoint.
Then I moved to Linux (Ubuntu) and OnlyOffice.
It worked very well with both documents, which were very complex in terms of advanced functionalities.
Also, AI integration is very easy as well as the other plugins

Cons: Basic functionalities:
- Math AutoCorrect doesn't work (-> should generate → for instance, or +- should generate ±, etc.) which is very annoying
For academics:
- Mendeley (a reference manager software) doesn't for desktop editors which is very limiting
- Zotero (another manager software) doesn't work well. So, a workaround is needed to update citation number by downloading and editing the script from GitHub (which as far as I know only works with flatpak and not snap)

Overall: OnlyOffice is a very good alternative to MS 365 and could be excellent by fixing those little details I mentioned above

Pros: Very intuitive and familiar interface - my father-in-law, 74 years-old, made the transition with a little set of instructions;
Full compatible docs with know formats - writing letters, reports, using spreadsheets, or creating presentations that can be opened elsewhere, without stress converting things;
Cross-platform - From PC to the smartphone, then online, again full compatible;
Tab experience - For the ones who loves it.

Cons: It's slow for opening small or big files - once opened, no lags, but takes it in advance;
Tab experience - For the ones who hates it;
Update process - sometimes this can change a small little thing you was used with...

Overall: The best alternative for Microsoft Office by far. No big learning curve. It's visually beautiful. Carry on your old docs.

Pros: ONLYOFFICE is easy to use, and a good alternative for users coming from proprietary and paid software, mainly due to its polished, beautiful and organized interface. The suite also has enough cloud features, and it is a great solution for teams which need to collaborate.

Cons: I just feel the lack of a database editor and manager.

Overall: I use ONLYOFFICE daily and like its features. The suite is powerful, user-friendly and has wonderful and beautiful UI.

Pros: Setup of system easy via Docker.
The interface of editor are easy to use and migration from Windows Office 365 to ONLYOFFICE are easy.

Cons: High usage of resources. QR module have a problem (not launching)

Overall: My customers have a good return for the usage with Nextcloud and the easy use of the system. Pricing model is good.

Pros: Document permissions are highly configurable, which is critical from a security standpoint. Real-time collaboration works smoothly without compromising access control. The platform supports on-premise deployment, offering better control over data flow. Audit logs and role-based access settings help ensure accountability across teams. Integration with existing LDAP and SSO systems made user management very straightforward.

Cons: UI response on large spreadsheets could be slightly more responsive at times, though it doesn’t affect core usability.

Overall: As a security analyst, I found ONLYOFFICE to be well-aligned with enterprise-level compliance and data control requirements. The flexibility of deployment and encryption support made it easy to recommend internally. It strikes the right balance between usability and governance. I genuinely feel confident using it for both technical documentation and collaborative planning.

Pros: What I like most is how straightforward ONLYOFFICE is. There’s no learning curve — everything feels familiar if you’ve used other office tools. Sharing documents with my team and editing them live has been smooth and reliable so far.

Cons: The only downside I’ve run into is that the desktop version takes a moment to start up on slower machines.

Overall: As a project manager, I need tools that don’t slow me down — and ONLYOFFICE delivers exactly that. It’s efficient, easy to collaborate with others, and handles all common document types without issues. Definitely worth using for daily tasks.

Pros: ONLYOFFICE makes it really simple to work on documents with others in real time. The interface is clean and intuitive, and I had no trouble opening or editing files I’d made in Word or Excel. It works well even on older PCs.

Cons: The mobile app could use some polish, and I noticed a few occasional formatting issues when importing complex Excel sheets.

Overall: ONLYOFFICE has been a dependable option for my day-to-day work. It covers all the essentials, doesn’t feel bloated, and the real-time editing is a huge plus for teams. I’d recommend it to anyone looking for a free yet powerful alternative.

Pros: ONLYOFFICE has a clean and familiar interface, great compatibility with MS Office files, and powerful collaboration tools. It's easy to set up, even for non-technical users, and works smoothly across devices.

Cons: Sometimes loading large documents takes a little longer, and a few advanced features are missing compared to MS Office.

Overall: Overall, ONLYOFFICE is a fantastic alternative to traditional office suites. It's reliable, user-friendly, and offers all the essential tools needed for document creation, spreadsheets, and presentations.

Pros: ONLYOFFICE allows us to create, edit and share documents, spreadsheets and presentations in a secure and controlled environment. In addition, the ability to control document access permissions and track versions ensures the integrity and confidentiality of the information we handle.

Cons: Although the platform offers a wide range of tools, I would like to have more options to tailor the look and feel and functionality to specific needs.

Overall: ONLYOFFICE is a robust and versatile tool to power document collaboration. It provides integrated capabilities, support for different formats and robust security controls.

Pros: Good collaboration capabilities for real time coauthoring. Compatible with Microsoft Office formats. Affordable licensing compared to mainstream office suites.

Cons: Missing some advanced features offered by Microsoft Office. Limited third party integrations & add-ons. Usability not as polished as leading products.

Overall: ONLYOFFICE provides a capable free & open source alternate to commercial office suites like Microsoft Office. Strong real time collaboration features at an affordable price point. However, the depth of features & third party integrations has gaps compared to market leaders.
