Tortus Technologies uses and believes in open-source software.
Both proprietary and open-source software are only as good as the team developing it. They both take experience, understanding and doing. But open-source software incurs no legal issues, licensing fees, maintenance fees, or upgrade fees. With open-source software, all you're paying for is your web development and hosting company's efforts and expenses. Proprietary software can result in countless licensing fees for all aspects of its development and deployment. There are numerous high-quality open-source offerings available. One can use Ruby on Rails to generate dynamic web pages, PostgreSQL (www.postgresql.org) or mySQL (www.mysql.com) to produce dynamic online databases, and the world-class Apache (www.apache.org) web server to publish your website to internet.
Open-source software is also more flexible than proprietary solutions. One can use Ruby on Rails with mySQL, or one can use PHP with PostgreSQL. And both these combinations and more can all be tied into Apache. Proprietary software vendors have an interest in forcing or coercing you into using all their software offerings. Thus one product may only work (or only work well) with the company's other products. This restricts web development and locks you into a system where you are forced to pay their fees, accept their license terms, and program your site using their methods. And in the case of the world-wide web, it can even restrict your audience.
