2017 - ONLYOFFICE integrates with SharePoint to catch up with LibreOffice

ONLYOFFICE, that competes with Microsoft Office and LibreOffice, released an app for SharePoint. So from now companies running SharePoint Server can use the most complete online office suite in SharePoint web interface. ONLYOFFICE is an open-source solution, free for up to 20 users that can be deployed on your private network. It promises 100% compatible with Microsoft Office formats and allows to collaboratively work on Word and Excel documents with a really complex formatting. Besides document editors it provides document management, email client, calendar, project management and community.

2017 - LibreOffice released in-house web version with collaborative online editing. ONLYOFFICE should better react

Document Foundation released the new version of its open-source office LibreOffice 5.3. It includes a bunch of new features, including a ribbon interface that resembles Microsoft Office. The foundation also made available the LibreOffice Online source code, which can be installed on servers. It noted: “The Document Foundation doesn’t have the resources or desire to set up an online service like Google Docs or Office 365. Instead, it is offering LibreOffice Online code that you can install on your own server. All you need is a single sign-on service and a file sync and storage solution like Nextcloud. Then just install LibreOffice, add users and start collaborating on documents. While individuals can install LibreOffice Online on their own servers, it’s aimed at ISPs and other cloud providers, giving them the ability to offer open source online collaborative suites to compete with Google Docs and Office 365.”

2014 - Teamlab opens source code, renames to ONLYOFFICE. LibreOffice keeps calm

Online team collaboration service Teamlab always wanted to become an Office - since the time when it got the own suite of office document editors. It's really oystanding, and Teamlab decided to make it the primary feature. At some point the developers even renamed the service to Teamlab Office. But even this wasn't enough for them. Yesterday (in honour of the 4th birthday) Teamlab was renamed to ONLYOFFICE. Although, as you can see on the site screenshot, it still includes not ONLY OFFICE, but also CRM, project management and document management tools. Beside the rebranding, the developers decided to fully open the source code of the product, so that the users could make sure in it's security. So, from now, if you want to install ONLYOFFICE on your own server - you can do it completely free.

2013 - New collaboration tools in ONLYOFFICE and LibreOffice

Microsoft recently launched the new Office 2013 and as usual with the release of new version there is a number of frustrated users that consider switching to competing products. So now is the best time for Microsoft rivals to push their office-suites. TeamLab (that recently became an "Office") added real-time collaboration feature. Now you can see who is working on a document at the moment, which paragraph he is editing and communicate with co-workers in comments and chat. You can even invite for co-editing users that are not registered in TeamLab. So TeamLab is now like Google Apps - they even set the same price $50/year. Only in Google Apps it's the price for 1 user, while in TeamLab - for 5 users. By the way, TeamLab's pricing is changed again: there is single edition and no free version.

The new version of LibreOffice 4 (the offspring of OpenOffice) was developed by much more people than TeamLab (after all, it's an open-source project). But it doesn't feature considerable updates. And there is no more talks about the promised mobile and cloud versions.

As usual, among the new features they claim the better support for MS Office formats. But in fact, formatting in a little more complicated documents distorts. At leats they added support for CMIS standard, that allows to collaborate on LibreOffice documents in different document management systems (Alfresco, Nuxeo, OpenText, etc.)

2011 - TeamLab Adds Online Docs and Speadsheets to defeate LibreOffice

TeamLab Docs and Speadsheets
Online collaboration service Teamlab continues to surprise us. Although recently it has finally introduced the paid edition, the main functionality remains absolutely free and not limited by the number of users. Nevertheless the Teamlab developers have enough time, funding and desire to create such new features as online document editors. Instead of integrating already existing editors, such as Google Docs or Zoho Docs, they created their own (competing) apps. The text editor and spreadsheets are already available in the free version. The presentation editor is coming soon. Of course, the functionality of these applications is far from Word, Excel and even Google Docs. They provide only the basic tools. But with most daily operations on document collaboration - they may cope. Documents created in Teamlab can be downloaded to DOC, XLS files and send to business partners. You can also upload documents in these formats and edit them online in Teamlab.
