Ahrefs is a multinational team with roots in Ukraine and headquarters in Singapore. We are a lean start-up company. We value making
meaningful and easy-to-use products. We shift things fast to give our customers what matters most to them, and to keep us ahead of the game. Our
motto is "First do it, then do it right, then do it better."
Our history
Ahrefs' history dates back to 2011, when we introduced the first version of Site Explorer after a year of preparation and data
mining. Site Explorer disrupted the stagnant field of backlink analysis and kick-started a new round of competition among SEO tool
providers. It quickly became one of the world's best backlink analysis tools.
From our humble beginnings, Ahrefs has steadily grown. We started out with a cluster of six servers, and gradually evolved
to our current, powerful 60 teraflops system. Today, we update our index with the freshest backlinks on the web every 15 minutes,
and the crawler processes up to 5 billion pages a day. That's more than a third of what Googlebot does!

from Wikipedia Software as a service (SaaS) is a software licensing and delivery model in which software is licensed on a subscription basis and is centrally
hosted. It is sometimes referred to as "on-demand software", and was formerly referred to as "software plus services" by Microsoft.
SaaS applications are also known as Web-based software, on-demand software and hosted software. The term "Software as a Service" (SaaS)
is considered to be part of the nomenclature of cloud computing, along with Infrastructure as a Service (IaaS), Platform as a Service (PaaS),
Desktop as a Service (DaaS), managed software as a service (MSaaS), mobile backend as a service (MBaaS), and information technology management as
a service (ITMaaS).
SaaS apps are typically accessed by users using a thin client, e.g. via a web browser. SaaS has become a common delivery model for many
business applications, including office software, messaging software, payroll processing software, DBMS software, management software, CAD
software, development software, gamification, virtualization, accounting, collaboration, customer relationship management (CRM), Management
Information Systems (MIS), enterprise resource planning (ERP), invoicing, human resource management (HRM), talent acquisition, learning
management systems, content management (CM), Geographic Information Systems (GIS), and service desk management. SaaS has been incorporated into
the strategy of nearly all leading enterprise software companies.
According to a Gartner estimate, SaaS sales in 2018 were expected to grow 23% to $72 billion.

LibreOffice is community-driven and developed software, and is a project of the not-for-profit organization, The Document Foundation.
LibreOffice is free and open source software, originally based on OpenOffice.org (commonly known as OpenOffice), and is the most actively
developed OpenOffice.org successor project.
LibreOffice is developed by users who, just like you, believe in the principles of Free Software and in sharing their work with the world
in non-restrictive ways. At the core of these principles are the four essential freedoms and the tenets of The Document Foundation's Next Decade
Manifesto [PDF].
We believe that users should have the freedom to run, copy, distribute, study, change and improve the software that we distribute. While
we do offer no-cost downloads of the LibreOffice suite of programs, Free Software is first and foremost a matter of liberty, not price. We
campaign for these freedoms because we believe that everyone deserves them.
from Wikipedia LibreOffice
is a free and open-source office suite, a project of The Document Foundation. It was forked in 2010 from OpenOffice.org, which
was an open-sourced version of the earlier StarOffice. The LibreOffice suite comprises programs for word processing, the creation and editing of
spreadsheets, slideshows, diagrams and drawings, working with databases, and composing mathematical formulae. It is available in 115 languages.
LibreOffice uses the international ISO/IEC standard OpenDocument file format (ODF) as its native format to save documents for all of its
applications. LibreOffice also supports the file formats of most other major office suites, including Microsoft Office, through a variety of
import/export filters.
LibreOffice is available for a variety of computing platforms, including Microsoft Windows, macOS, and Linux (including a LibreOffice
Viewer for Android), as well as in the form of an online office suite LibreOffice Online. It is the default office suite of most popular Linux
distributions. It is the most actively developed free and open-source office suite, with approximately 50 times the development activity of
Apache OpenOffice, the other major descendant of OpenOffice.org.
The project was announced and a beta released on 28 September 2010. Between January 2011 (the first stable release) and October 2011,
LibreOffice was downloaded approximately 7.5 million times. The project claims 120 million unique downloading addresses from May 2011 to
May 2015, excluding Linux distributions, with 55 million of those being from May 2014 to May 2015.

from Wikipedia OpenOffice.org (OOo),
commonly known as OpenOffice, is a discontinued open-source office suite. It was an open-sourced version of the earlier
StarOffice, which Sun Microsystems acquired in 1999 for internal use.
OpenOffice included a word processor (Writer), a spreadsheet (Calc), a presentation application (Impress), a drawing application (Draw),
a formula editor (Math), and a database management application (Base). Its default file format was the OpenDocument Format (ODF), an ISO/IEC
standard, which originated with OpenOffice.org. It could also read a wide variety of other file formats, with particular attention to those from
Microsoft Office.
Sun open-sourced the OpenOffice suite in July 2000 as a competitor to Microsoft Office, releasing version 1.0 on 1 May 2002.
In 2011 Oracle Corporation, the then-owner of Sun, announced that it would no longer offer a commercial version of the suite and donated
the project to the Apache Foundation.
Apache renamed the software Apache OpenOffice. Other active successor projects include LibreOffice (the most actively developed) and
NeoOffice (commercial, only for macOS).
OpenOffice.org was primarily developed for Linux, Microsoft Windows and Solaris, and later for OS X, with ports to other operating
systems. It was distributed under the GNU Lesser General Public License version 3 (LGPL); early versions were also available under the Sun
Industry Standards Source License (SISSL).
from Wikipedia Snagit
is a screenshot program that captures video display and audio output. Originally for the Microsoft Windows operating systems, recent
versions have also been available for macOS, but with fewer features. It is created and distributed by TechSmith and was first launched in 1990.
Snagit is available in English, German, Japanese, and Korean versions.
Snagit replaces the native print screen function with additional features. Newer versions allow batch capture of embedded items such as
links, pictures, and multimedia. The user can set parameters and keyboard shortcuts to capture particular types of data, which are stored in a
folder called "Catalog" by default. The software can also follow links in web pages, capturing the specified data from the linked pages.
Accessories, such as Flickr Output for uploading screen captures to a Flickr account, can extend its capabilities.
is a free and open source email, newsfeed, chat, and calendaring client, that’s easy to set up and customize. One of the core
principles of Thunderbird is the use and promotion of open standards - this focus is a rejection of our world of closed platforms and services

What is Open Source Software?
Thunderbird is open source software, meaning that anyone can inspect, modify, enhance it, and share it. But the fun is not just for
programmers! Thunderbird is created by a community of designers, translators, documentation writers and support people in addition to developers.
We invite anyone to come and participate in the creation of Thunderbird. Regardless of your skillset, we’re sure there is something you can add
to our community and project.
from Wikipedia Mozilla Thunderbird is a free and open-source, cross-platform email client, news client, RSS, and chat client developed by the Mozilla
Foundation. The project strategy was modeled after that of the Mozilla Firefox web browser. It is installed by default on Ubuntu desktop
systems.
On December 7, 2004, version 1.0 was released, and received more than 500,000 downloads in its first three days of release, and 1,000,000
in 10 days.
On July 6, 2012, Mozilla announced the company was dropping the priority of Thunderbird development because the continuous effort to
extend Thunderbird's feature set was mostly fruitless. The new development model shifted to Mozilla offering only "Extended Support Releases",
which deliver security and maintenance updates, while allowing the community to take over the development of new features.
On December 1, 2015, Mozilla Executive Chair Mitchell Baker announced in a company-wide memo that Thunderbird development needs to be
uncoupled from Firefox. She referred to Thunderbird developers spending large efforts responding to changes to Mozilla technologies, while
Firefox was paying a tax to support Thunderbird development. She also said that she does not believe Thunderbird has the potential for
"industry-wide impact" that Firefox does. At the same time, it was announced that Mozilla Foundation will provide at least a temporary legal and
financial home for the Thunderbird project.
Since the memo in 2015, Mozilla has brought Thunderbird back in-house in an announcement on May 9, 2017, and continues to support its
development. The Thunderbird development team has also expanded by adding several new members and has undergone an overhaul on security and
user-interface.
