Free Online Courses on Udacity

If you decide to complete the whole nanodegree, you can choose to upgrade to the paid version. 

Udacity Free Courses Vs. Paid Courses

Now I know you hopped on to this article to learn about “FREE” courses on Udacity. But this is for those who may feel like upgrading to the paid version after getting a taste of the free version. (Trust me, it’s very tempting to do so)

You might ask yourself, “What can I get from the paid version that I cannot get from the free version?” fair shout. 

And that’s precisely why I decided to add this section to this article. Below, I will discuss the main perks of being a paid student. 

  • Career Services

Beyond nanodegrees, Udacity’s career services extend comprehensive support after program completion.

Providing a range of services like resume support, GitHub portfolio review, and LinkedIn profile optimization, positioning you for your ideal role to kickstart your career journey.

  • Udacity Certificate

Upon successfully finishing a nanodegree with Udacity, you earn a certificate. Certificates are exclusively awarded when completing specific nanodegree programs such as web development or app development. 

Numerous programs collaborate with major companies like Google and Microsoft, increasing the chances of being recognized by potential employers. 

  • Full Access

The free version limits your access to 200 courses, but investing in the paid version opens up a broader range of topics for students from all skill levels to learn a popular programming language without any programming experience. 

Udacity continuously introduces new paid courses, expanding the range for those who invest in their learning. 

  • Real World Projects

You will be working on real-world projects guided by industry experts. The courses are structured to provide practical, employable skills through real-world projects, allowing for flexible learning and technical mentor assistance around the clock. 

  • Technical Support

Udacity’s paid programs allow you to be guided by experienced mentors to help you smoothly complete your course. These mentors can answer your questions, motivate you, and assist you in keeping you on track throughout your learning journey.

Udacity Pricing and Refund Policy

Recently, Udacity changed its pricing structure from a product-based model to a subscription-based one. And what’s the difference?

a screenshot of the udacity pricing plans

Back then, you select one course or nanodegree program and pay for it individually. You only get access to that specific program.

But now, you pay a monthly/annual subscription and get access to the whole course catalog. You can’t enroll in one specific course or nanodegree program. Think of it like Netflix: you pay a subscription fee to watch any movie you choose.

How much does it cost? You can pay $249 for a monthly subscription or $846 for a four-month subscription and save 15% by paying upfront. 

You can cancel your subscription and get a full refund within the first fourteen days of subscription (seven days for non-EU students).

Note that this only applies in the first month of your subscription, and one student only gets one refund.

Alternative Platforms That Provide Free Online Courses

If you can’t find a free online course on Udacity under the niche you’re looking for, you can explore other online learning platforms offering free courses from various niches. 


Coursera partners with prominent universities to create advanced-level courses and serves a wide range of niches, with over four thousand courses and over fifty million students providing bachelor’s and master’s degree programs. 

Like Udacity, Coursera’s pricing structure is the same: subscription-based. However, Coursera also provides the option of paying for a course individually. 

If you pick the “audit the course” option, you can learn for free on most courses, but you won’t get an official certificate when you finish.

Once you’ve selected the free audit course, you can upgrade to the paid option anytime during the audit period.


Similar to Coursera, edX provides a free course audit option.

Teaming up with renowned universities and companies such as Harvard and Berkeley, edX lets you access all course materials for free with the audit option.

While certificates aren’t provided upon course completion, and access to the course isn’t retained, the focus remains on the valuable knowledge gained throughout the learning experience. 

And if you want to upgrade to a verified certificate, you can do so.
