ClearOS Alternatives

Chromium OS is an open-source project that aims to build an operating system that provides a fast, simple, and more secure computing experience for people who spend most of their time on the web. Here you can review the project's design docs, obtain the source code, and contribute. We think of Chromium as a tabbed window manager or shell for the web rather than a browser application. We avoid putting things into our UI in the same way you would hope that Apple and Microsoft would avoid putting things into the standard window frames of applications on their operating systems. The tab is our equivalent of a desktop application's title bar; the frame containing the tabs is a convenient mechanism for managing groups of those applications. In future, there may be other tab types that do not host the normal browser toolbar.

The Courier mail transfer agent (MTA) is an integrated mail/groupware server based on open commodity protocols, such as ESMTP, IMAP, POP3, LDAP, SSL, and HTTP. Courier provides ESMTP, IMAP, POP3, webmail, and mailing list services within a single, consistent, framework. Individual components can be enabled or disabled at will. The Courier mail server now implements basic web-based calendaring and scheduling services integrated in the webmail module. Advanced groupware calendaring services will follow soon. The Courier mail server's source code should compile on most POSIX-based operating systems based on Linux, and BSD-derived kernels. The Courier mail server should also compile on Solaris and AIX, with some help from Sun's or IBM's freeware add-on tools for their respective operating systems. The Courier mail server evolved out of several related projects, that merged together (more on that later). The Courier mail server implements SMTP extensions for mailing list management.

Our end to end Unified Communications technology begins with the platform CommuniGate Pro.

It includes all the software you'd expect for your daily tasks — email, web browsing, word processing, gaming, and much more. With a small community of dedicated developers, MidnightBSD strives to create an easy-to-use operating system everyone can use, freely. Available for x86, AMD64 and as Virtual Machines. The FreeBSD project has developed a reliable server operating environment, but often usability and performance on the desktop is overlooked. Scheduling, allocation of resources, security settings, and available application support should be tailored to desktop users. Many of the BSD projects are tailored to servers or older hardware. Others are distributions of FreeBSD with a nice graphical user interface, but still suffer from server-centric design under the hood. We did not fork FreeBSD as a result of a falling out, but rather as an excellent starting point.

Exim is a mail transfer agent (MTA) used in Unixllike operating systems. The first version was written in 1995 by Philip Hazel for use in the University of Cambridge Computing Service's e-mail systems. Exim is distributed under the GPL, and therefore is free to download, use and modify. Exim somewhat resembles Smail 3, but it has diverged and now surpasses it in user friendliness and flexibility. They both follow the Sendmail design model where a single main binary controls all the facilities of the MTA. This monolithic design is considered by some to be inherently less secure and slower, but despite this, Exim's security record is much better than Sendmail and comparable with Qmail and Postfix, as is its speed. In advanced areas such as queue handling, address routing and testing, it exhibits excellent performance. Exim doesn't have a Graphical User Interface (GUI) to help you configure it, but some Linux distributions add one.

Alpine Linux is an independent, non-commercial, general purpose Linux distribution designed for power users who appreciate security, simplicity and resource efficiency. Alpine Linux is built around musl libc and busybox. This makes it smaller and more resource efficient than traditional GNU/Linux distributions. A container requires no more than 8 MB and a minimal installation to disk requires around 130 MB of storage. Not only do you get a fully-fledged Linux environment but a large selection of packages from the repository. Binary packages are thinned out and split, giving you even more control over what you install, which in turn keeps your environment as small and efficient as possible. Alpine Linux is a very simple distribution that will try to stay out of your way. It uses its own package manager called apk, the OpenRC init system, script driven set-ups and that’s it! This provides you with a simple, crystal-clear Linux environment without all the noise.

If you’re already running openSUSE you can upgrade by booting from the DVD/USB and choosing upgrade, or carry out an ‘Online Upgrade’ in a few commands. Leap is a classic stable distribution approach, one release each year and in between security and bugfixes. This makes Leap very attractive as server operating system, but as well for Desktops since it requires little maintenance effort. openSUSE Leap is compatible with SUSE Linux Enterprise; this gives Leap a level of stability unmatched by other Linux distributions and provides users the ability to migrate to an enterprise offering.

Windows XP is a version of the Microsoft Windows operating system for personal computers. It was released to manufacturing on August 24, 2001, and to retail on October 25, 2001. The "XP" in Windows XP stands for "eXPerience". Windows XP is a direct upgrade to its predecessors, Windows 2000 for high-end and business users and Windows Me for home users. It replaced Windows 2000 and Windows ME, which helped bring the NT and 9x versions of Windows together. Windows XP is a graphical user interface (GUI) that allows you to use different types of applications or software. For example, you can use a word processing application to write a letter and a spreadsheet application to track your financial information. Windows XP is known for its bright color schemes, easy-to-use interface, and stability. It was one of Microsoft's longest-running flagship operating systems, lasting at least 5 years. It was succeeded by Windows Vista on January 30, 2007.
