Share of US job postings in each pay band; the dark bar holds the average, the striped bar the 25th percentile. Source: ZipRecruiter salary data collected in 2020-21, when this FAQ was first written; pay has moved since, so treat it as a rough guide.
Paid Udemy video courses include a certificate of completion when you finish; free courses and practice-test-only courses do not. It shows you did the work, but it is not an accredited qualification. Coursera and edX usually charge for a certificate, issued with the university or company that made the course.
1
The Complete Ruby on Rails Developer Course (2026)
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.
-
- 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)
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.
-
- 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)
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.
-
- 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)
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.
-
- 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)
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.
-
- 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.
