Go - The Complete Guide (Udemy.com)

Learn Go ("Golang") from the ground up & in great depth by building multiple demo projects, incl. a REST API

Created by: Maximilian Schwarzmüller

Last updated November 2025

Our take

Based on the ratings of 9,795 students and a sample of their written reviews, the syllabus, the course as of November 2025. No course pays to be reviewed.

This is a language-first Go course from Maximilian Schwarzmüller, published in late 2023 and refreshed in November 2025, so the material is current. About 15 hours across 199 lectures cover values, pointers, structs, interfaces, generics, slices, maps, and goroutines, then two projects: a small price calculator and a REST API with authentication and a SQL database. The audience list says beginners, but the requirements ask for basic programming experience in some language, and the pace suits people who have it. Around 58,000 students have enrolled and nearly 9,800 have left reviews, with a 4.7 average.

Students praise the teaching the way they do in his other courses: clear, quick, and to the point, with reviewers saying the lessons are well structured and easy to follow. The main complaint is the word Complete in the title. Two three-star reviews call it a good first dip in the language rather than a full guide, and a four-star reviewer calls it more a syntax course than a backend course. Concurrency gets 42 minutes and one reviewer wanted more detail there. Another wished for a section on wiring up Postgres or MySQL and deploying the API. There are no quizzes or coding exercises, so practice is on you.

Value is good for the time asked. The REST API project gives it a practical edge over syntax-only tutorials. For anyone who wants a well-taught tour of the language with one real project at the end, it's an easy recommendation. Experienced Go developers looking for advanced concurrency patterns or production backend work will outgrow it quickly, and the reviews say as much.

Best forDevelopers who already know one language and want a clear, current Go foundation with one real API project at the end.
Skip it ifYou already write Go and want deep concurrency patterns, deployment, or production backend design.

Pros

  • Clear, fast explanations that reviewers say get to the point without rambling
  • Ends with a real REST API project: authentication, SQL database, 219 minutes of lectures
  • Updated in November 2025, so the material is not stale
  • About 95% of nearly 9,800 reviews give it four or five stars

Cons

  • Not as complete as the title suggests; one reviewer calls it a syntax course, not a backend course
  • Concurrency section is only 42 minutes and one reviewer wanted more depth
  • No quizzes or coding exercises, and nothing on deploying the API or configuring Postgres or MySQL
Well structured, easy to follow and understand. Some rather complex concepts (sucah as closures and variadic functions) are only lightly touched, but those need proper individual research to understand anyways.
Peter Nagy, a student

Listed as all levels, but the requirements ask for prior programming experience in any language; true first-timers will struggle.

Instructor Details

Maximilian Schwarzmüller

Experience as (Web) Developer

Starting out at the age of 12 I never stopped learning new programming skills and languages. Early I started creating websites for friends and just for fun as well. Besides web development I also explored Python and other non-web-only languages. This passion has since lasted and lead to my decision of working as a freelance web developer and consultant. The success and fun I have in this job is immense and really keeps that passion burningly alive.

Starting web development on the backend (PHP with Laravel, NodeJS, Python) I also became more and more of a frontend developer using modern frameworks like React, Angular or VueJS in a lot of projects. I love both worlds nowadays!

I also build full-stack applications and acquired expert DevOps and cloud computing knowledge - proven by the many AWS certifications I hold (incl. the top-level Solutions Architect Professional certification).

As a self-taught developer I had the chance to broaden my horizon by studying Business Administration where I hold a Master's degree. That enabled me to work in a major strategy consultancy as well as a bank. While learning, that I enjoy development more than these fields, the time in this sector greatly improved my overall experience and skills.

Overall, this is a great course for begineers and people looking for a refresher who are starting their Go (Golang) Journey as well as developer looking for a refresher. The concept are. explained clearly and the course is easy to follow. One area that could be improved is the cocurrency section ( require more details) Overall, I would recommend this course to anyone who wants to learn or refresh their Go Knowledge

By Hüsamettin Gündüzoğlu on 7/5/2026

There are some missing parts, it is more like a Go syntax course but as Go is a language directly developed for backend, I would prefer a course with a backend focus. Moreover, I would prefer to change working directory/file while moving on with more complex examples in order to keep simple ones for the future to check the subject.

By David Mermoud on 6/3/2026

I found this course very good. At first, it felt tedious having to handle errors explicitly in every function, but by the end, I understood that this explicit error handling is fundamental to Go. Overall, the course is highly recommended, especially for understanding Go’s core philosophy.

By Lucas Vieira Proença dos Santos on 5/6/2026

Eu esperava entrar aqui sem saber NADA de GO e sair com o básico de entendimento de linguagem, pra onde ir e o que avançar, e foi exatamente o que eu consegui! Superou minhas expectativas. Com uma didática incrivel, aulas rápidas e diretas ao ponto, com muita prática! Recomendo fortemente

By Andrea Minuto on 4/27/2026

Overall, this course provides a solid introduction to the Go programming language. Go itself is an interesting technology, especially considering its focus on performance, simplicity, and concurrency, and these aspects are clearly presented throughout the course. The instructor deserves particular praise: the explanations are clear, well-organized, and engaging. Complex concepts are broken down effectively, making the learning experience smooth even for developers approaching Go for the first time. From a teaching perspective, the course is definitely well executed. That said, I personally found Go’s syntax to be a significant drawback. It feels unintuitive and aesthetically unpleasant, reminiscent of older-generation languages such as Fortran. This stylistic rigidity makes the language less enjoyable to write and harder to appreciate, especially when compared to more modern and expressive alternatives. Because of this, despite the quality of the course and the instructor’s competence, I don’t see myself choosing Go voluntarily for future projects. I would only consider using it if explicitly required by a client or by strict project constraints. In summary, this is a well-taught course about an interesting language, but one whose syntax and overall feel strongly limit its appeal—at least for my personal preferences as a developer.

By Kyrylo Romantsov on 4/20/2026

Essentials are well covered by Maximillian as usual, but I do not think it's a 'complete guide' as concurrency model is covered only high-level, no memory leaks mentioned, some popular packages like gorm or packages for testing are missing. Also, from the basics, I would like to have a lesson on source structure. Again, the course is great, I like the mentor a lot, this is the 3rd course by Max I've completed, just the title is a bit misleading.

By Francia Díaz on 3/27/2026

The course is good for beginners, and I really appreciate the instructor's effort. I would have liked more depth in the section on parallelism and goroutines, applying different design patterns, and how to structure an application, perhaps using clean architecture. Nevertheless, I think it's a good course for laying the foundation.

By Yogesh Rautela on 3/26/2026

Easy to understand language. The level rised up gradually, It didn't felt increasing much throughout the coursed though ... kudos to how well this is organised. I do felt a need to improve tricky topic like interface and make it more understandable, probably more examples. Other than that I think .. I understood 80 - 90 % things at first. Highly recommend this to someone who is starting golang or want to learn this.

By MP Wdev on 3/18/2026

I really like and recommend this Go course from Maximilian and @Academind. It starts with simple examples and gradually moves on to more complex cases, culminating in a REST API project (including authentication with JWT tokens and an SQL database). Building the project from the ground up helped me understand and practice the core concepts. Thank you, Maximilian and the @Academind team!

By Konstantin on 1/31/2026

Max is amazing! The course materials are perfectly structured, and his delivery is one of the best I've encountered. The information is easy to digest, the pace is comfortable, and there's nothing superfluous. I really enjoyed the course. Thank you, Max, you do incredible things!
