Two kinds of people search for "free Duolingo alternative." Some genuinely need zero cost, whether because money is tight or because they are not ready to commit to something paid before they know it works for them. Others are really asking a different question: is there something better than Duolingo, and do I have to pay for it?
The answer to the second question is mostly no. Some of the best tools for language learning are free or very close to it. And the one paid option worth considering costs less than three months of Duolingo's own premium tier.
Here is an honest rundown of the best options in 2026, in rough order of how much we recommend them.
Best free Duolingo alternative: Anki for vocabulary and retention, Language Transfer for grammar and sentence building. Both are completely free and both outperform Duolingo in their respective areas. For Mandarin specifically, HelloChinese has the best free tier of any Chinese app.
Anki is a flashcard app powered by spaced repetition, and it has been the quiet backbone of serious language learning for over a decade. Unlike Duolingo's SRS, which runs on a fixed algorithm you cannot touch, Anki's is fully customisable. You set how aggressively it pushes you on new words, how quickly it advances cards you find easy, and how long it waits before showing you something you got wrong.
The community has built shared decks for almost every language imaginable. A well-made deck for Japanese, Spanish, or Mandarin, paired with native speaker audio on each card, is more efficient for vocabulary retention than anything Duolingo offers. The research backs this: retrieval practice with expanding intervals, which is what Anki does, is one of the most robustly supported methods for long-term memory encoding in the cognitive science literature.
The learning curve is real. Anki is less immediately intuitive than Duolingo and requires you to find or build your own decks rather than having lessons prepared for you. But for pure vocabulary retention, nothing free comes close.
Language Transfer covers Spanish, French, German, Italian, Greek, Turkish, Arabic, Swahili, and Mandarin. It is audio-only, available as a free download or through any podcast app, and was built by one teacher who made it free because he believed it should be. There are no ads, no premium tier, no email sign-up required.
The format is Socratic: the teacher speaks with a learner on the recording, asking them to work out how the target language functions rather than simply telling them. You listen and answer aloud. It feels more like thinking than studying. Each course runs between 10 and 20 hours and takes you from zero to a point where you have a genuine working model of how the language is put together.
For grammar, it is the best free resource I have come across, full stop. It does not replace vocabulary work, but if you combine Language Transfer with Anki you have a very solid foundation built entirely for free.
This one surprises people but it should not. A substantial body of research, much of it associated with Stephen Krashen's input hypothesis, suggests that listening to language just above your current level produces faster acquisition than structured drilling. Native content at the right difficulty level, where you understand most but not all of what you hear, is one of the most efficient paths to fluency.
For Spanish learners, Dreaming Spanish has built an enormous library of graded video content across beginner, intermediate, and advanced levels. Most of it is free on YouTube, with some content behind a low-cost Patreon. For Japanese, channels like Comprehensible Japanese follow the same model. French, German, and Mandarin all have equivalents.
30 minutes of graded listening per day will do more for your long-term vocabulary and listening comprehension than most paid apps. The challenge is discipline: there is no streak counter pushing you to open YouTube, which is exactly why Duolingo retains users even when its outcomes are weaker.
Noun Town is a language learning game for PC and Mac, and it has a free demo on Steam that gives you a genuine taste of the experience before spending anything. The game puts you in a 3D open world where objects and environments are labelled in your target language, characters speak to you in native speaker audio, and speech recognition lets you practise producing language out loud.
It supports 12 languages: Japanese, Korean, Mandarin, Spanish (Spain and Mexico), French, German, Italian, Russian, Greek, Egyptian Arabic, and English. The Noun Town language learning game uses spaced repetition to bring vocabulary back at the right intervals, and sessions typically run longer than users expect because it does not feel like a chore.
More than 200,000 learners have used it across the series, with 87% positive from 590+ Steam reviews. The demo is genuinely free and worth 20 minutes of your time before deciding anything else.
Most articles in this space avoid talking about price honestly, so here it is plainly:
If you are going to be learning a language for more than three months, which most people intend to do, Noun Town is cheaper than Duolingo Plus over any meaningful time horizon. It is cheaper than three months of Duolingo Plus in absolute terms. This is not a budget versus premium comparison. It is just the math.
None of which means you should automatically spend money. Try the free demo first. Try Anki and Language Transfer, which cost nothing. See what sticks. The point is that "free" is not always the lowest cost option when you account for the full picture.
If you are learning Mandarin, HelloChinese has a free tier that covers significantly more ground than Duolingo's Mandarin course and handles tones and characters much more seriously. For Chinese specifically it is the strongest free app available.
Memrise has a free tier and uses native speaker video clips, which is a genuine advantage for learning how words actually sound. The free version is more limited than it used to be, but it is worth trying if you are learning one of its well-supported languages.
Busuu has an interesting feature in its free tier: native speakers can correct your written and spoken practice. The free version is restricted but the feedback mechanism is genuinely useful, particularly for people who have no other access to a human speaker of their target language.
None of these replace Anki for retention or Language Transfer for grammar. But they each do something specific reasonably well, and depending on your language and learning style, one of them might slot in usefully alongside the core free stack.
Anki is the most powerful free option for vocabulary and retention, using a customisable spaced repetition system that outperforms Duolingo's in rigour and flexibility. Language Transfer is the best free grammar resource for the languages it covers. Both are completely free and work well together.
For vocabulary retention, Anki's free version is stronger. For grammar understanding, Language Transfer covers more ground. Duolingo's genuine advantage is daily habit formation through its streak system, which matters because consistency is most of the battle in language learning. Whether a free app "beats" Duolingo overall depends on what you are measuring.
Yes, there is a free demo on Steam for PC and Mac. The full game is $19.99 as a one-time purchase with no subscription, covering all 12 supported languages. The demo gives you a real experience of the 3D vocabulary learning environment, native speaker audio, and spaced repetition system before you spend anything.
Free on desktop and Android. The iOS app is a one-time purchase of around $25, which funds development of the free versions on other platforms. No subscriptions, no ads, no paid content required. Thousands of shared community decks are freely downloadable for most major languages.
Noun Town at $19.99 once. Duolingo Plus costs $6.99 per month ($83.88 per year). Over one year, Noun Town costs less than three months of Duolingo Plus. Over two years, the difference is roughly eight to one.
