Duolingo vs Babbel
Short answer: Babbel if your language is one of the few it takes seriously and you want structured explanation you can follow. Duolingo if you want a daily habit, a wider choice of languages, or you want to spend nothing, because its free tier carries the same lesson content as its paid one.
The thing neither comparison table tells you: both products' headline promise moves. Babbel's own help centre says the price varies by your location, your subscription term and type, and whether you buy from Babbel, a partner site, Google or Apple. Duolingo's own help centre says a Super feature may be missing because it runs tests on subscriptions and features. So Babbel's variable is the price and Duolingo's variable is the product, and a single confident number or feature list for either, ours included, would be a snapshot rather than a fact. Verified July 28, 2026.
Start here: which language do you actually want?
This is the question that settles it for most people, and it usually gets buried under feature grids. Babbel says it offers "13 languages for English speakers", across 14 courses because Spanish is taught as two. That number sounds like breadth. What matters far more is how far each course goes, which Babbel publishes itself using CEFR levels.
| Language | Course goes up to |
|---|---|
| European Spanish | C1, with additional topics to B2 |
| French | B2/C1, with additional topics to B2 |
| German | B2, with additional topics to C1 |
| Italian | B2, with additional topics to B2/C1 |
| Mexican Spanish | B1 |
| Portuguese (Brazil) | B1, with additional topics to B2 |
| Swedish | B1, with additional topics to B2 |
| Dutch | B1, with additional topics to B2 |
| Danish, Norwegian, Indonesian, Polish | A2 |
| Turkish | A2, with additional topics to A2/B1 |
| Russian | A1, with additional topics to A2 |
CEFR runs A1 (beginner) to C2 (proficient). So Babbel will carry you to a genuinely advanced level in European Spanish, and to a solid intermediate one in French, German and Italian. In Russian its course stops at A1, and in Danish, Norwegian, Indonesian and Polish at A2, which is a few months of study rather than a language you will use. None of that is hidden, but "13 languages" is what gets advertised and the ceiling is what you actually buy.
Duolingo's list is much longer, including many languages Babbel does not teach at all. The trade is the obvious one: breadth against depth, and a course existing is not the same as a course being finishable.
The free question, and why Duolingo wins it by default
Babbel has no meaningful free tier, so if spending nothing is the requirement, the comparison is over before it starts.
What is more interesting is what Duolingo's paid tiers actually sell. Duolingo states that it offers the same lesson content to all users. Read that carefully, because it means a subscription is not unlocking course material you were locked out of. Super Duolingo removes ads, gives unlimited hearts so mistakes stop interrupting you, adds personalised practice built from your errors, and gives unlimited Legendary attempts. Those are real improvements to the experience. They are convenience, not content.
That reframes the decision honestly: with Duolingo you are deciding whether to pay to remove friction, and it is fine to decide no. With Babbel you are paying for the course itself, because there is no other way in.
Duolingo Max: two things to check before you pay
Max is Duolingo's flagship tier, adding AI features on top of Super: Explain My Answer, Roleplay conversations with its characters, and Video Call with Lily. Two limits are worth knowing first, and both come from Duolingo's own documentation.
It is mobile only. Duolingo Max is available in the iOS and Android apps and cannot be purchased through the website. People who subscribed on the web cannot upgrade to it, and the Max features do not run on the web platform. If you are someone who studies at a desk on a computer, Duolingo's headline tier is simply not available to you, which is a strange thing to discover after paying.
The AI features are not in every course. Explain My Answer and Roleplay are for English speakers learning French, Spanish, German, Portuguese or Italian, plus speakers of several languages learning English. Video Call with Lily covers a similarly short list and needs iOS or Android 13 or later. Duolingo says that on an unsupported course you still get the Super benefits, which is fair, but it also means paying for Max while learning Japanese or Korean buys you Super.
The part both products keep quiet: the offer itself moves
Babbel is unusually straight about this. Its help centre states that the cost of a subscription can vary depending on your location, the duration and type of your subscription, and whether you purchase directly through Babbel, partner websites, Google or Apple. It also explains that the monthly figure shown on its pricing pages is the total divided down to show the value of a longer commitment: you pay the full renewal period in advance, and only Lifetime and the gift option are one-time payments.
Duolingo's moving part is different. Asked why a subscriber might not see unlimited hearts in Super, its help centre answers that this may be down to a test, and that it frequently tests changes including small tests on subscriptions and features. The practical meaning is that two people paying for the same tier can hold different feature sets.
This is why we publish no price for either product on this page. It is not caution for its own sake: Babbel has told us its number depends on where you are and where you buy, and Duolingo keeps its numbers in the app stores. A confident figure here would be a guess dressed as a fact, and it would be stale by the time you read it.
Our verdict
Choose Babbel if you are learning Spanish, French, German or Italian, you want explanation and structure rather than streaks, and you accept that you are buying a course with a known ceiling. Choose Duolingo if you want to spend nothing, if your language is not one Babbel takes far, or if the hardest part for you is showing up daily, which is the problem Duolingo is genuinely best in the world at solving. Skip Duolingo Max unless you are on mobile and learning one of the handful of languages its AI features actually support.
There is one thing neither of them does, and it is the thing that separates people who study a language from people who speak one: nobody qualified is listening to you. Both are self-study tools, and both are honest enough not to promise otherwise. The usual fix is not a third app but a person, and the cheapest version of that is a community tutor rather than a language school.

Frequently asked questions
Is Duolingo or Babbel better?
Neither is better in general, and the honest answer depends on one thing most comparisons skip: which language you want. Babbel goes deep in a small set, mostly big European languages, and its own help centre publishes the ceiling for each one, from C1 in European Spanish down to A1 in Russian. Duolingo covers far more languages but its paid tiers buy convenience rather than extra content, because Duolingo states the lesson content is the same for everyone. Pick Babbel if your language is one it takes seriously and you want structured explanation. Pick Duolingo if you want a daily habit, a wider choice of languages, or you want to spend nothing.
How much do Duolingo and Babbel cost?
We deliberately do not quote a single figure for either, and the reason comes from the companies themselves. Babbel states that the cost of a subscription can vary depending on your location, the duration and type of subscription, and whether you buy directly from Babbel, partner websites, Google or Apple. Duolingo does not publish prices in its help centre at all, because they sit inside the app store. Third-party pages that give you one confident number for either product are quoting a figure that may not be the one you are shown. Check the total on the confirmation screen, and note Babbel bills the full renewal period in advance.
Is Duolingo free version good enough?
For most people learning casually, yes, and this is the part worth understanding before paying. Duolingo states that it offers the same lesson content to all users, so a paid tier is not unlocking course material you were missing. Super Duolingo removes ads, gives unlimited hearts so mistakes do not stop your session, adds personalised practice on your errors and unlimited Legendary attempts. That is convenience, and whether convenience is worth a subscription is a fair question rather than an obvious yes. Babbel has no comparable free tier, so the free route is Duolingo.
Is Duolingo Max worth it?
Check two things before you pay, because both can rule it out entirely. First, Duolingo Max is only available in the iOS and Android apps and cannot be bought through the website, and people who subscribed on the web cannot upgrade to it. If you prefer to study on a computer, the flagship tier is not available to you. Second, its AI features do not exist in every course: the Explain My Answer and Roleplay features are for English speakers learning French, Spanish, German, Portuguese or Italian, plus several languages learning English, and Video Call with Lily covers a similar short list on iOS and Android 13 or later. Outside those, paying for Max leaves you with Super features.
Can either one make me fluent?
No, and neither claims to replace speaking with people. Both are self-study products: you tap, you type, you repeat, and you get good at recognising a language. The gap they share is that nobody qualified is listening to you and correcting you. That is not a flaw in either app, it is the shape of the category. Most people who get genuinely conversational use an app for vocabulary and habit and add real conversation practice separately, which is why our recommendation at the end is not a third app.
How we reach these verdicts, and the sources behind them, is on our methodology page. Babbel's language count, the CEFR ceiling for every course, the statement that price varies by location, term, type and purchase channel, the advance-billing model and the fact that only Lifetime and the gift option are one-time payments were read from Babbel's own help centre and verified July 28, 2026. Duolingo's tier structure, the statement that the same lesson content is offered to all users, the Super benefits, the limits on Duolingo Max including that it cannot be bought through the website and that its AI features are restricted to a short list of courses, and its answer that a missing Super feature may be down to a test were read from Duolingo's own help centre and verified July 28, 2026. No price is quoted for either product because Babbel states its cost varies by location and purchase channel and Duolingo does not publish prices outside the app stores; third-party figures we found contradicted each other and were not used, and no promotional or sale pricing appears here. Duolingo's help centre served us its Turkish edition, so nothing from Duolingo is quoted verbatim on this page and its positions are described in our own words. We do not mention Duolingo's reported energy system because Duolingo's own documentation still describes hearts and we could not resolve the contradiction. Neither Duolingo nor Babbel is a Fawnio partner and we do not link to either. We earn a commission if you sign up to italki through our link; it appears only as the answer to the gap both products share, and each is credited plainly where it is the better choice, including the case for using Duolingo for free.
