LibreOffice is a free and open-source Office Suite from The Document Foundation, presented as the successor to OpenOffice.org. The suite includes Writer (word processing), Calc (spreadsheets), Impress (presentations), Draw (vector graphics and flowcharts), Base (databases), and Math (formula editing).
Ethercalc is very well suited for developing modern-day enterprise (smaller-mid size), finance and healthcare applications as it can do Real-time data pull from a variety of third-party apps, and has interoperability with CSV, Microsoft Excel and JSON files; It's available on all on all public clouds including AWS, GCP and Microsoft Azure and can be used as a Low code and no code development tool. Further, we can Develop applications on the go with good integration and visualization libraries and we can also do Tabulation and graphing along with ability to use it as an npm module, do Real time collaboration and editing. It is a very good tool for startups and government institutions. There is a considerable scope of improvement for using it in bigger enterprises as it needs key integration and interoperability functionalities. It can evolve in a variety of directions depending upon its integration with a variety of third party apps services and tools. As an analytics tool, for example, it needs integration with R, Scipy, Numpy and keras libraries. Availability within Ionic, NativeScript or Appgyer as an extension or a plugin will be very useful for it being used as a large enterprise low code/no code tool.
The fact that it is free of charge for desktop use sets LibreOffice at the top of my list. Given our low software budget, and its feature set which is for all intents and purposes equivalent to big name brands, it is more than appropriate for our needs. I have noticed in some situations that exporting a spreadsheet in a particular format on my machine and then sharing it with someone who is using say Microsoft Excel results in unexpected behavior (i.e., formatting issues or unreadable data).
It's free, which is the biggest difference between Office. It definitely feels like a full-fledged office suite of software for no more than the cost of an optional donation.
Lots of templates exist out on the internet for Writer and Impress (the Word and PowerPoint equivalents in LibreOffice). The open source community really likes to support one another in their usage of each other's software.
It works smoothly on almost every OS out there, including Windows, MacOS, and Linux.
We use it consistently and have a lot of documents in the OpenDocument format so it will be necessary to use LibreOffice or a compatible product such as Openoffice in the future to be able to open these files. Because the license fee for Libreoffice is zero it is not very costly to keep using it - the costs are mostly for keeping it installed on the office PCs and regularly updated, and solving employee issues with the user support.
Most people can quickly start using Writer or Calc or Impress for basic tasks even if they see Libreoffice for the first time, because the interface is similar to older (97-2003) MS Office or other software. Some features are less intuitive than in recent MS Office and some power users of MS Office need to re-learn some things before being proficient in Libreoffice.
Libreoffice is a desktop app not requiring any server part so it is always available when the PC is working normally. Installing it on another machine if one PC fails is very quick and easy. This is a non-issue.
For big/imported tables or text documents with images loaded from the internet it is sometimes getting very slow, RAM and CPU intensive, and sometimes even hangs due to some memory leaks or other bugs. This is a long-term problem and is still not resolved perfectly.
Support is not officially offered. However, you can find answers to any usage questions or trouble-shooting online easily, typically starting with a Google search. (I believe that all forums / tips for OpenOffice apply equally to LibreOffice, and vice versa.) While Microsoft Office, for example, officially includes support, I find that typically you end up going to a Google search in any case. So, this is not really a downside. However, in all these cases, you end up doing a lot of figuring things out for yourself.
Generally easy to perform, issues are how to ensure regular automatic updates on Mac OS X. Fortunatly we have only a few machines with OS X run by management and we can do these updates manually occasionally. Windows updates are quite easy with the support of third party software such as Ninite or Chocolatey, and Linux updates are super-easy thanks to the package manager (apt-get).
EtherCalc has a low barrier to entry on training and end-user development. It is very easy for startups with considerable time pressure to deliver to use EtherCalc as a tool for tabulation, organization, collaboration and computation. It is also very useful for use cases in government institutions where there is a strong push for open source software-based ERP solutions or app development. These are the key reasons for the selection of Ethercalc.
I have used MS Office, Google Docs as other comparable products. I like MS Office best of all. I like LibreOffice better than Google Docs; however, I believe that if Google Docs wasn't so limited in many of its features and web-based only, I think it has the potential to surpass LibreOffice if they don't fix the problems between full functionalities.
With more users using it in the company there are more cases when a simultaneous editing of the same document is needed and this feature is lacking in Libreoffice even though the files concerned are shared and synced by some solution (we use ownCloud). Google Docs or MS Office365 via Sharepoint/Onedrive offer a better function for this.
Very good opportunities on using it as a low code, no code tool with ionic open source platform. Able to meet needs of our customers and do real time deployment quickly
Very productive and useful for developing web APIs and PWAs on the cloud, tablet, mobile and a variety of surface devices (touch functions can be customized according to needs)
Spreadsheet for the next 100-150 years as it integrates well with React, Angular and Jquery libraries. Maintainable and readable code of spreadsheet
Low barrier to entry on training and end user development
Good analytics and accounting tool for startups
What you see is what you get interface
The ability to integrate with firebase and Dropbox is neat.
Being a free GNU-based software, it is ideal for computers used outside the company's network or for users which do not require online collaboration tools.
Importing and exporting word processing documents is easy. PDF functionality is adequate and works very well.
You will probably need to invest in fonts if, for example, most of your company is using Microsoft Word fonts, which may be proprietary. In our case, we paid for a few key fonts; installation in the system was simple but done through IT, not the user.
For complex graphs and presentations, LibreOffice may not be the best alternative.
