How we rate online learning platforms
Every ranking on Skillvlora comes from a published formula, not from opinion or payment. This page explains what data we track, how the platform picker scores it, how the cost calculator works, and where our method falls short.
Method last updated: October 6, 2026
What we track for every platform
Each platform in our database is a single record with the same set of fields. Using identical fields for every platform, free or paid, is what makes side-by-side comparison fair.
| Field | What it means |
|---|---|
| Pricing model | Subscription, pay per course, or free. |
| Starting price (USD) | The lowest standard monthly price for subscriptions, or a typical single-course price for pay-per-course platforms. |
| Certificate type | Free, paid, or none. We note when a certificate is only available after payment. |
| Refund or trial | Free trial, free tier, audit option or refund window, as stated by the platform. |
| Topics | The subject areas the platform covers, such as data, AI, programming, business and design. |
| Goals | Whether it suits career change, a specific skill, or learning for fun. |
| Learning style | Video lessons, in-browser practice, or project-based work. |
| Last checked | The date we last confirmed the record against the platform itself. |
How we collect and check the data
Collect
We read each platform's own pricing, plan and certificate pages and enter the details by hand into our database.
Date it
Every record gets a check date. That date is shown next to the price on the site so you can judge how fresh it is.
Re-check monthly
We revisit every record each month and update anything that changed. We also publish what changed in our monthly price report.
Publish from one source
The quiz, comparison table, calculator and price report all read from the same database, so a fix in one place updates all of them.
We enter data by hand and do not scrape platform sites. Platforms can change prices or run sales at any moment, and many show different prices by country, so always confirm the final price at checkout before you pay.
How the platform picker scores platforms
When you finish the five-question quiz, every platform in the database receives a score out of 10 based only on your answers and the fields above. We show your top three, along with the reasons each one scored well.
Why these weights
Topic carries the most weight because a platform that does not teach what you want is useless however cheap it is. Goal, budget and certificate come next because they decide whether a platform is worth paying for. Learning style gets one point because most people can adapt to a different format if the content is right.
How each factor is matched
| Factor | Points | When a platform earns them |
|---|---|---|
| Topic match | 3 | The platform covers the topic you picked. |
| Goal match | 2 | The platform is a fit for your goal: career, a specific skill, or personal growth. |
| Fits your budget | 2 | Free platforms always fit. If you chose "low", the platform must be low-cost or free. If you chose "up to about $30 per month", mid-priced and low-cost platforms fit. If you chose "best fit", every platform fits. |
| Certificate preference | 2 | If you do not need a certificate, every platform earns these points. If you want a free certificate, the platform must offer one. If you will pay for a recognized one, platforms with a paid or free certificate qualify. |
| Learning style match | 1 | The platform supports the style you picked: video, in-browser practice, or projects. |
Breaking ties
When two platforms finish with the same score, the one with the lower starting price ranks higher. Nothing else, including any commercial relationship, is used to break a tie.
A worked example
Say you want to change careers into data, you can spend up to about $30 per month, you want a certificate you will pay for, and you learn best by practicing in the browser. Here is how three platforms would score.
| Platform | Topic (3) | Goal (2) | Budget (2) | Cert (2) | Style (1) | Total |
|---|---|---|---|---|---|---|
| DataCamp | 3 | 2 | 2 | 2 | 1 | 10 |
| Codecademy | 3 | 2 | 2 | 2 | 1 | 10 |
| Coursera | 3 | 2 | 0 | 2 | 0 | 7 |
Tie-break in action: DataCamp and Codecademy both score 10, so the lower starting price decides the order and DataCamp is listed first. Coursera scores lower because its starting price sits above the mid-budget range and it is built around video and projects rather than in-browser practice.
This is an illustration of the method. Platform records in our database change as we re-check them, so live quiz results may differ.
How the cost calculator works
The calculator answers one question: for the number of courses you will really finish, is a subscription or buying courses one by one cheaper? It uses three formulas and nothing hidden.
If you finish more courses than the break-even number within your subscription period, the subscription is cheaper. If you finish fewer, single purchases win. The calculator also shows your effective cost per course on a subscription, which is the subscription total divided by the courses you finish.
You can prefill the monthly price from any subscription in our database or type your own. We recommend counting only courses you are confident you will complete, since unfinished courses are what make subscriptions expensive.
Our standards for reviews and comparisons
Written reviews and head-to-head pages follow the same rules as the database.
- Current prices only. Every price in a review comes from the platform's own page and carries a check date.
- First-hand testing. We aim to base verdicts on using the product ourselves, for example by running the same task on two platforms, and we say so when we have not tested something.
- Honest downsides. Each review lists real drawbacks, not just strengths.
- Verdict near the top. You should not have to scroll to find out who a platform is for.
- Verified offers only. Our savings pages list offers we have confirmed, with a date. We remove expired ones quickly and say plainly when no code is needed.
Updates and corrections
Every record is re-checked monthly, and the date on each row shows the last check. If a platform changes its pricing between checks, our number can be out of date until the next review, which is why we ask you to confirm at checkout.
If you spot an error, tell us. We verify the claim against the platform and fix confirmed mistakes quickly. Please send the platform name, the field you think is wrong, and a link to the page that shows the correct detail via our contact page.
Independence and how this site is funded
Skillvlora does not currently earn money from the platforms we list. Rankings come from the formula on this page, and no platform can pay to change its score or position. If that ever changes, for example through affiliate links, we will disclose it clearly on the pages where it applies and on this page, and the scoring will stay the same.
What our method cannot do
A scoring formula is a shortcut, and it has limits you should know about.
- It does not measure course quality. The picker matches your needs to platform features. It does not score how good an individual course or instructor is.
- It uses starting prices. Plans, regional pricing and sales vary, so your checkout price can differ from ours.
- It cannot predict whether you will finish. The calculator assumes the number of courses you enter. Real completion depends on you.
- It covers a limited set of platforms. We track a defined list and add more over time. A platform missing from the database is not a negative judgment.
- It does not judge employer recognition. Certificate type tells you whether one exists and what it costs, not how much weight a given employer gives it.
Use the results as a well-organized starting point, then check the platform's own page before you commit.
