Best Udemy Coding Courses (2026): Expert Picks by Topic
Last updated:
Five instructors still teach coding courses on Udemy worth paying for in 2026: Jonas Schmedtmann, Maximilian Schwarzmüller, Angela Yu, Colt Steele, and the Andrei Neagoie and Daniel Bourke team. Each tops its topic below, with the hours and the projects. Scrimba's free interactive courses cover the same ground if you would rather code than watch.
Verified against each course's live Udemy listing and against our own coverage of Scrimba's courses, September 2026.
The best Udemy coding course by topic
| Course | Instructor | Best for | Verdict |
|---|---|---|---|
| The Complete JavaScript Course (opens in a new tab) | Jonas Schmedtmann | JavaScript from zero | ~70 hours, six builds including the Forkify recipe app. Still the safest first pick. |
| React: The Complete Guide (opens in a new tab) | Maximilian Schwarzmüller | React plus Next.js and Redux | ~71 hours, refreshed for React 19, ends with a full-stack Next.js app using the App Router. |
| 100 Days of Code (opens in a new tab) | Dr. Angela Yu | Python beginners who need a habit | ~60 hours across 100 daily projects. The commitment device does the work. |
| The Web Developer Bootcamp (opens in a new tab) | Colt Steele | A full-stack bundle in one purchase | ~73 hours, ends in YelpCamp, a database-backed app with auth and deploy. |
| Complete A.I. & Machine Learning, Data Science Bootcamp (opens in a new tab) | Andrei Neagoie & Daniel Bourke | Classical ML and data science in Python | ~45 hours, pandas through TensorFlow, four graded projects. |
Each row is the single course we would buy in that topic. The topic pages below rank two more options per subject and explain when the runner-up fits better.
How we picked these five
We ran every candidate through the same filter: "Last updated" inside the past 12 months on the Udemy landing page, 4.5 stars or better across tens of thousands of ratings (not hundreds), a project-heavy syllabus instead of slideshow sections, and an instructor still answering Q&A. Courses that fail any one of those get dropped, no matter how high the enrollment number.
Sales are constant on Udemy. If a course above shows full price, wait a few days; the platform runs near-permanent discounts on almost everything in its catalog.
Udemy coding courses by topic
Each topic page ranks the courses we would actually recommend and names the popular ones that are quietly outdated.
- Best Udemy JavaScript Courses: fundamentals through async and the DOM.
- Best Udemy React Courses: hooks, state, and routing, with notes on which courses still teach class components to skip.
- Best Udemy Python Courses: general-purpose Python plus the automation and data-science angles Udemy covers well.
- Best Udemy Web Development Courses: the full-stack bootcamp-style bundles, where Udemy's lifetime model pays off.
- Best Udemy AI & Machine Learning Courses: from applied building to the math-heavy ML tracks that need a real instructor.
Scrimba's free Learn JavaScript course (opens in a new tab) puts you in the editor instead of the video player. The rest of this page assumes you have already decided on Udemy's format.
When does Udemy beat an interactive course?
Udemy wins on a niche topic subscription platforms skip: Unity, Kotlin, an AWS or Azure cert crammer, advanced Excel, or a single deep dive you want to own forever. You buy it once and keep it.
Udemy loses when the goal is sustained practice toward a web or AI job. Passive video trains recognition, not recall, and that gap is where tutorial hell comes from. A format that forces you to type inside the lesson closes that gap faster than a 70-hour video watched at 1.5x.
| Situation | Better fit |
|---|---|
| A guided web or AI path with in-lesson coding | Scrimba |
| Java, Kotlin, Unity, Excel, or an AWS cert crammer | Udemy |
| One inexpensive deep dive to own forever | Udemy |
| A subscription plus Discord plus certificates | Scrimba Pro |
| Active practice to break out of tutorial hell | Scrimba |
Scrimba's free courses cover the fundamentals
If the table above sold you on a niche Udemy pick, buy it. If you are still deciding how to learn JavaScript or React in the first place, Scrimba's free courses answer that without a purchase.
Learn JavaScript, taught by Per Borgen, runs about 9.4 hours across eight modules and builds four things, including a blackjack game in 55 scrims. Learn React, taught by Bob Ziroll, runs about 15 hours across six projects, the biggest of which wires a form to the Claude API to build a recipe generator called Chef Claude. Both put you inside the code instead of watching someone else type.

For JavaScript from scratch, Jonas Schmedtmann's The Complete JavaScript Course. For React, Maximilian Schwarzmüller's React: The Complete Guide. For Python, Angela Yu's 100 Days of Code. Each cleared our 4.5-star, actively-maintained, project-heavy filter in September 2026.
Scrimba if you want to type inside the lesson and finish a guided path with a community. Udemy if you want a specific niche topic Scrimba does not cover, or a one-off video course you own for life.
Wait for a sale. Udemy runs near-permanent promotions, so list price is rarely what people pay.
They prove you finished, not that you can code. Employers weigh shipped projects and how you talk through your code in an interview far more than a completion certificate.
Yes. Use Scrimba's interactive courses to build the core habit and fundamentals, then buy a Udemy course for a niche topic Scrimba's subscription does not cover.
