🇮🇩 The best courses for learning Indonesian

Foreign Service Institute, Peace Corps and DLI materials — full textbooks plus hundreds of hours of audio — are public domain and hosted here for free across dozens of languages. The depth is extraordinary and the FSI Basic courses take diplomats to professional working proficiency, which no consumer app attempts. The recordings are from the 1960s–80s, the drills are relentless, and some vocabulary is dated (Cold War era), so they suit disciplined self-studiers, not casual learners.

Mihalis Eleftheriou records real lessons with a real student and walks you through constructing the language yourself using cognates and logic — Spanish, French, Italian, German, Greek, Turkish, Arabic and Swahili are covered. Completely free, no ads, no sign-up, funded by donations. The Spanish course in particular is one of the most recommended free resources anywhere; the trade-off is small vocabulary and no reading or writing practice.

Covers 14 languages along an explicit CEFR path, and its best feature is the community exchange: you submit short writing or speaking exercises and real native speakers correct them, free of charge, in exchange for you correcting theirs. The free tier is limited to core lessons; Premium unlocks grammar, offline and the full path. A solid Babbel alternative if you specifically want writing practice with human feedback.

Mark Pentleton teaches a genuine student while you listen in, across French, Spanish, German, Italian, Chinese, Swedish, Portuguese, Japanese and Gaelic. The podcast seasons are free on any podcast app and are structured as a real curriculum rather than scattered episodes; the Academy sells premium lesson notes, video and bonus audio. Ideal commuting material for beginners through B1, and the Spanish and French series are the strongest.

Innovative Language's Indonesian arm is the largest organised body of dialogue-based audio lessons for the language, each with a line-by-line transcript, vocabulary list and cultural note. It is the most reliable way to get from zero to comfortable listening, and the free account plus the YouTube channel already cover a lot of ground. Caveats: the site pushes subscriptions hard, the lesson navigation is genuinely confusing, and the upper levels thin out fast — expect to leave it around B1/B2.

Each course is ~100 short bilingual dialogues with native audio: you passively absorb for months, then start an 'active wave' translating back into the target language. Books run around €30 (e-courses ~€50) across 70+ languages, and the method is a long-standing favourite among polyglots for reaching real reading fluency. Caveats: many courses are only published from French, the humour is dated, and it demands daily discipline with no gamification to carry you.

Subscription-only after a handful of free intro lessons, typically $10–15/month with big discounts on annual plans. Lessons are short, dialogue-first and explain grammar properly, which makes it a much more serious beginner course than Duolingo. It covers only 13 languages and effectively stops around B1, so it is a stepping stone rather than a destination.

One of the first officially accredited Indonesian language schools in Bali, running since 2011 with campuses in Ubud and Sanur plus private online classes that follow the same syllabus. For expats and long-stay visitors it is the standard recommendation, and the teachers are trained in BIPA methodology rather than improvising. It is real tuition at real prices, and the fee chart is only visible after you dig into the site.

Over 70 languages, each a step-by-step beginner course written by an experienced teacher, and crucially all the audio is free to download from the companion site even if you find the book secondhand. Slightly more academic and grammar-forward than Teach Yourself, which some learners prefer. Like any book series the individual titles differ in quality; the less common languages are often the only decent course in existence.

You listen to and repeat thousands of native-recorded sentences on a spaced schedule, which builds fluent output patterns without explicit grammar study. It covers 60+ languages and keeps nine minority languages (Catalan, Welsh, Taiwanese, Kurdish and others) permanently free as a preservation effort. It is expensive at roughly $20–40/month, and the repetition is monotonous — most reviewers call it effective but overpriced, so try the 7-day trial first.

A long-established school that maps its Indonesian programs to CEFR levels and issues progress reports, which matters if you need documented proficiency for a job or a visa rather than just conversational ability. Classes run one-to-one or in small groups, in Jakarta or online. Pricing is corporate-training territory, so it is overkill for a casual learner — the appeal is structure and accountability.

Lessons build outward from real conversations with colour-coded literal translations and cultural notes, and the catalogue includes endangered and indigenous languages nobody else covers. Retail pricing starts around $10/month, but a very large number of public libraries and universities give patrons free access — check yours before paying. Content depth per language is modest, so it suits travellers and early learners more than people pushing toward B2.

You sit in on a recorded lesson with two students and build sentences aloud alongside them, with no writing, homework or memorisation; 19 languages are available. It is remarkably good at making the core grammar of Romance languages click in a few hours. Vocabulary coverage is small, the recordings are old, and the courses after Michel Thomas's death are taught by other teachers with mixed results — treat it as a fast on-ramp, not a course of study.

Thirty-minute audio lessons force you to produce sentences out loud before you see anything written, which builds unusually good accent and recall. Subscriptions run about $15–21/month (all-access covers 50+ languages), and older courses are often available through public libraries. It is slow and vocabulary-light by design, so pair it with reading — but for commute or walking time it is the best use of otherwise dead hours.

A self-study course of dialogue lessons recorded with speakers from Jakarta, Yogyakarta, Bali and Surabaya, deliberately teaching the colloquial Indonesian people actually use rather than the formal register textbooks lead with. The $97 lifetime price with no subscription is unusual and fair if you finish it. Be aware that most of the glowing reviews online come from sites affiliated with the product, and there is little free sample material, so judge it from the demo lessons before paying.

The 'Complete' books are proper structured courses with dialogues, graded exercises and downloadable audio, and the range covers languages no app touches. Quality varies noticeably by title and author, so check reviews for your specific language before buying rather than trusting the series name. Their graded readers and 'Script Hacking' alphabet guides are also worth knowing about for non-Latin scripts.
