Udemy Review 2025 – The World's Largest Online Course Marketplace

Udemy, founded in 2010, is one of the largest online learning platforms with over 250,000 courses and millions of monthly users. From Python and SQL to machine learning, AI, business, and even photography, it covers nearly every subject.

In this Udemy review, we’ll explore what it does well, where its marketplace model has drawbacks, and whether it’s a smart choice for skill-building in 2025.

Udemy offers a learning experience far beyond a single niche. You can find courses on popular tech skills like Python, R, JavaScript, and SQL, as well as in-demand fields such as data science and machine learning. This variety also extends to non-tech subjects like photography, personal development, and business. This sheer volume of content means you'll almost always find a course on the topic you want to learn.

Once you purchase a course, you get lifetime access to its content. This is a huge advantage, as you can learn at your own pace without the pressure of a subscription deadline. You can revisit lessons, refresh your memory on key concepts, and access any course updates the instructor publishes in the future, all at no extra cost. 

Many courses on Udemy include downloadable resources, quizzes, and even coding exercises to encourage hands-on practice. Some instructors provide real-world projects, which can be invaluable for building a portfolio. Additionally, the Udemy Personal Plan offers access to a curated library of courses, some of which feature labs and AI-powered coding exercises, providing a more interactive experience similar to specialized platforms.

The open marketplace model allows anyone to become an instructor, which results in a highly diverse pool of teachers. This means you can find an instructor with a teaching style and background that perfectly matches your learning preferences. Whether you prefer a concise, project-based approach or a detailed, lecture-style format, the variety of instructors increases your chances of finding a course that resonates with you.

While DataCamp has a vast library, a large portion of its content is geared toward beginners and intermediate learners. Many users find that while the platform is excellent for learning the basics and syntax of languages like Python, R, and SQL, it lacks the in-depth, advanced content needed to become a true expert. The interactive, "fill-in-the-blank" format can be a crutch, not fully preparing learners for the open-ended, real-world problem-solving challenges they'll face in a professional role. 

Since content creators are responsible for their own updates, courses can become obsolete quickly in fast-paced fields like web development and AI. This can be frustrating for learners who encounter deprecated code or outdated best practices, making the course less effective for current industry standards.

Many courses on Udemy are primarily video-based lectures. While this is great for absorbing information, it can be a disadvantage for skills that require a hands-on approach. The courses often lack structured, project-based learning or practical exercises to reinforce concepts, which can make it difficult for learners to apply what they've learned in real-world scenarios.

Individual Course Purchase: A one-time payment for a single course. This grants you lifetime access to all course materials, including any future updates. This is the traditional and most popular way to use Udemy.

‍Udemy Personal Plan: A monthly or annual subscription that provides unlimited access to a curated courses library. This plan includes content on a variety of topics, from tech skills like AI-powered coding exercises to business and marketing.

Udemy has become a household name in online education with its unique model as an open online marketplace. The learning experience is defined by an huge library of over 200,000 courses, giving users the freedom to explore almost any topic imaginable, from programming and data science to creative writing and photography. A major pro for many users is the platform's affordable pricing and lifetime access to a course after a single purchase, which allows you to learn at your own pace and revisit material anytime.

This open model is also the source of the platform's biggest drawback: highly variable content quality. Since anyone can become an instructor, the quality of a course can differ wildly in production value, content depth, and accuracy. This can make the learning experience a "treasure hunt" where you have to rely heavily on user reviews and ratings to avoid a poorly-made or outdated course, which is a common complaint in many Udemy reviews.

Furthermore, the platform's learning experience is often criticized for a lack of structure. Because courses are individual products, there is no curated structured learning path to guide you from beginner to expert, which can be a major con for those seeking a full career change. The learning itself is primarily video-based, and while some courses include projects and quizzes, there is generally very little direct interaction with the instructor. This can make the experience feel like a solo journey, and while the certificates of completion are a nice feature, they are not officially accredited and do not hold significant weight with most employers.

Finding the right Udemy top courses is a great first step, as the platform is a massive online marketplace of popular and highly-rated classes. Its strength lies in its diverse offerings, with top courses that are perfect for beginners looking to learn both in-demand tech and professional skills.

With a massive library of courses, it's an excellent choice for exploring a new topic, from Python and JavaScript to machine learning and photography. Its lifetime access model and frequent sales make it accessible to almost any budget.

Udemy has several drawbacks: courses often lack personalized guidance and direct instructor support, content can become outdated quickly in fast-paced fields, and many courses don't provide enough hands-on practice, making it difficult to apply new skills.
