About

We help you find the best course.
Not the most promoted one.

Finding the right online course shouldn't require visiting ten different platforms, manually comparing prices, and wondering whether that 5-star rating was paid for. Learn By Source indexes courses from every major provider and gives you the information you need to choose — clearly, honestly, and without a sales pitch.

How we evaluate courses

Every course is evaluated across six dimensions. Editor's Picks meet a high threshold across all six.

Learner ratings
Aggregated from verified platform data — not editorial opinion.
Enrollment numbers
Real demand signal. Widely enrolled courses have proven resonance.
Instructor credentials
Institution affiliation, industry background, and teaching history.
Certificate recognition
Whether the cert is recognized by employers and how widely.
Curriculum recency
When the course was last updated and whether the content reflects current tools.
Price transparency
What is genuinely free to audit, what requires payment, and what total cost looks like.

How we find and display courses — and what drives our rankings

Learn By Source participates in affiliate programs with Coursera, Udemy, Pluralsight, and others. When you click a link and enroll, we may earn a commission — at no extra cost to you. The price you see is always the same as going directly to the provider.

This revenue funds the platform. It does notinfluence our course rankings, Editor's Picks, or comparison results. If a free course is the best option for a topic, we say so. We never accept payment for featured placement.
