Opensource হচ্ছে বিশ্বের নিবেদিতপ্রাণ প্রোগ্রামারদের তৈরিকৃত ফ্রি সফটওয়্যার, যা অর্থ দিয়ে কেনার প্রয়োজন নেই। এগুলো সম্পূর্ণ ফ্রি। এ ধরনের সফটওয়্যার ব্যবহারে আইনগত কোন বাধা নেই। Opensource সফটওয়্যারগুলি অনেক ক্ষেত্রেই ক্রয়কৃত সফটওয়্যারের চেয়েও ভাল হয়ে থাকে। উদাহরণস্বরুপ, ওয়েব ডিজাইনের Opensource সফটওয়্যার Joomla বা WordPress এর ব্যবহার ও চাহিদা সমগ্র বিশ্বে সর্বাধিক। নিম্নে বিষয়ভিত্তিক Opensource সফটওয়্যারের লিস্ট ও ডাউনলোড লিংক প্রদত্ত হল।
