Ruby on Rails is a powerful web development tool that adds a back end dimension to front end skills like HTML, CSS, and JavaScript. While Rails is a crucial skill to add if you already have tech skills, it's also user-friendly enough to be a totally manageable entry point into programming and web development.

Yes and No. Certified Ruby on Rails developers on average make more money. Having a Ruby on Rails certificate greatly increases the chance of landing an interview and can open otherwise closed doors. Coursera, Udacity and EdX offer excellent certificate options for impressing your future employers. Eduonix, Udemy and several other providers offer certificates, but they aren't as reputable. If you have a Computer Science Degree, certificates are not as important. Still, many employers won't care about certificates, but rather your interview skills, experience and/or skills assessment.

1
The Complete Ruby on Rails Developer Course (2026)
4.5
Udemy's Bestseller-badged Rails course, 48 hours and six apps from a CRUD blog to a SaaS product, still teaching well but stuck on Rails 5 and 6 with a quiet Q&A.
Best for: Self-reliant beginners who want the full Rails workflow, testing, git and deployment included, and can Google around version errors.
Pros
Cons
-
- Covers automated testing, git and deployment, which reviewers note most Rails courses skip.
- Six projects of rising difficulty, including ActionCable chat, Stripe payments and a SaaS app.
- Explanations are detailed enough that one student with no coding background reports landing a job.
- Fellow students have posted fixes for most of the version roadblocks in the discussions.
-
- Frozen at Rails 5 and 6; students on Rails 7 or 8 hit errors generating projects and old gems.
- Instructor Q&A goes unanswered, one 2026 review says for over a year, and reviews back to 2019 say the same.
- The Ruby primer is thin and the later sections have had less updating than the early ones.
2
Learn Ruby on Rails from Scratch (2018)
4.0
A ten-hour Eduonix run through Ruby basics, Rails routes, models and a Heroku deploy that builds one app end to end, still useful as a fast overview despite its age.
Best for: Working developers who need a quick picture of how a Rails app fits together and can patch version differences themselves.
Pros
Cons
-
- Compact at under ten hours, so it works as an overview or a refresher in a weekend
- Builds one complete app from setup through models, an admin panel and Heroku deployment
- Reviewers call the explanations clear and easy to follow, even at 1.5x speed
- Seven quizzes and a certificate, and the setup lectures cover both Windows and Mac
-
- Teaches Ruby 1.9.3 and an old Rails release; migrations and Heroku steps no longer match
- Instructor troubleshoots his own mistakes on camera, which several students found unprepared
- Assumes HTML, CSS and some JS despite the all-levels label, and pasted code goes unexplained
3
Dissecting Ruby on Rails 5 - Become a Professional Developer (2021)
4.4
A 43-hour, job-focused Rails 5 build of a full portfolio app, with deep dives on the hard parts and an instructor who reviewers say actually answers questions.
Best for: Bootcamp grads and self-taught coders who can follow a tutorial but can't yet build a Rails feature from scratch.
Pros
Cons
-
- Deep dive lecture at the end of each section explains the reasoning, not just the commands
- Reviewers say Q&A replies come fast and the comments already hold fixes for most breakages
- Goes past CRUD into ActionCable live updates, authorization, drag and drop, and a Heroku deploy
- Real workflow habits: Pivotal Tracker, GitHub pull requests, and debugging taught as its own section
-
- Core lessons are from around 2017; expect gem and version breakages unless you pin Rails 5
- No testing section, which reviewers flag as the missing piece
- Slow start, rushed finish, and nearly five hours on styling; one reviewer asked for less frontend
4
Testing Ruby with RSpec: The Complete Guide (2026)
4.7
A tight 7.5-hour RSpec course from Boris Paskhaver that teaches testing plain Ruby objects, matchers, and mocks, with a 4.7 rating from over 2,000 reviews.
Best for: Ruby developers who've never written a test and want RSpec explained clearly with examples, summaries, and assignments.
Pros
Cons
-
- Every video pairs code examples and use cases with a summary, so the structure is easy to follow
- Covers let, hooks, subjects, shared examples, matchers, and doubles in a logical order
- 10 assignments and 3 quizzes; reviewers report using the material at work right away
- Refreshed January 2026 and built for Ruby 3, unusual for a testing course first published in 2019
-
- No Rails coverage: it tests plain Ruby, not models, controllers, or a database
- The instructor talks fast and types faster; two reviewers found the code sections hard to follow
- Mocks section is short on practice, and Q&A responses have been slow per a 2023 review
5
8 Beautiful Ruby on Rails Apps in 30 Days & TDD - Immersive (2016)
4.3
A free, project-only Rails course that builds eight lookalike apps (Instagram, Tumblr, a Hacker News forum) in about 16 hours, with almost no theory between them.
Best for: Beginners who want to build eight small Rails apps back to back and learn the conventions by repetition, not by reading.
Pros
Cons
-
- Free, and eight finished apps means beginners come away with portfolio pieces, not just notes.
- Learn-by-building approach; reviewers say Rails MVC and CRUD conventions stick after a few repetitions.
- Clear, well-produced videos; one working developer called it a decent refresher on Rails views.
- Covers real features: image uploads, star ratings, voting, user logins, HAML, and a Heroku deploy.
-
- Last updated in 2016 and built on an older Rails, so expect small fixes to run it on current versions.
- The eight apps reuse the same pattern, and low-star reviews call it repetitive and too basic.
- TDD is a single lecture at the end, and none of the projects are built test-first.
