If you have been programming for a few years, then you know that Software design or System design is one of the tricky concepts to master. You can quickly learn a programming language like Java or Python, but creating software using that programming language is a different thing.

That's where software design and coding skills comes to rescue. It's an art to structure your program, design your modules, specify boundaries and interactions with other parts of the system so that they are easier to read, maintain, and flexible to change.

It's one of the essential skills for a software developer but often gets ignored. If you look for an online course to learn Software design and architecture, you won't find many, forget about good ones.

At the same, time if you look for courses to learn Java, Python, or JavaScript, you will find tons of classes.

That's why we have tons of programmer who knows Java, Python, and JavaScript but when it comes to software development, system design, coding, and software design then often struggle.

To help my readers with this problem, I did some research and come up with this list of best Software/System design and Architecture online courses.

You can take these courses to build this powerful skill which will serve life long. Unlike programming languages, frameworks, and libraries, this skill also doesn't become outdated in a few years.

Btw, prepare to work hard. Just joining and the online course won't be enough as most of the people just join the course without actually completing it or doing what the instructor says.

You don't learn when you join and online course, you learn, when you work and apply the knowledge you have gained. That's where project-based courses shine. They encourage you to use your experience to solve real-world problems, and you will find a couple of such classes on this list.

Top 15 Software Design and Architecture Courses for Programmers on Udemy in 2025

Without wasting any more of your time, here is my list of some of the great, interactive, and fun online courses to learn Software design and Architecture.
