Udemy at a glance
Udemy is a marketplace: independent instructors create and price their own courses, and Udemy handles payments, hosting and promotion. You can buy individual courses (which come with lifetime access to that course for as long as it remains available) or subscribe to a Personal Plan for access to a subset of the catalog. Companies use a separate product, Udemy Business.
Udemy runs promotions so frequently that the "list price" is rarely what people pay. If a course you want is at full price, it is usually worth waiting for the next sale.
Udemy's biggest strength — and weakness
Because anyone can publish, Udemy covers niche, practical topics nobody else does. The same openness means quality ranges from excellent to poor. Our Udemy review explains the five checks we use before buying any course.
Certificates
Udemy issues certificates of completion, not accredited credentials. They are fine for showing initiative, but employers will care more about the skills and projects you can demonstrate.
