Duolingo Scraper

🦉 Collect public Duolingo courses, learners, and vocabulary as structured data

This Actor helps language teachers, course designers, researchers, and developers collect public Duolingo data without signing in. It returns structured rows about Duolingo languages. Rows cover courses, learner profiles, weekly league standings, and vocabulary. You can compare courses, review learner streaks and XP, or build word lists for a language pair, without copying each page by hand.

Use it to:

• Compare Duolingo language courses by learner count, source language, and release phase.
• Filter learner profiles by total XP, streak, or Super status, starting from usernames or profile links.
• Track weekly league standings for a list of learners, including tier, wins, and placement history.
• Build a Duolingo Spanish vocabulary list with translations, skills, and units for a language pair, such as Spanish taught in English.
• Recheck a monitored lookup and receive only the new or changed records.

🧩 Four kinds of public Duolingo data

• Courses: language courses with their teaching and learning languages, learner counts, and release phase.
• Learner profiles: public names, streaks, total XP, languages, and current course. Enrolled courses and achievements are included when the source shows them.
• League summaries: each learner's weekly league tier, wins, podium finishes, and placement history.
• Vocabulary: words and phrases for one language pair, with translations, skills, and units.

Each row is public data that was read and checked successfully. Failed, private, invalid, or unreadable targets go to the warning log, not the dataset.

3. Start the run. When it finishes, open the Output tab to see the rows.

⚙️ Input

Choose one result type first. Fields for other result types are ignored.

❓ FAQ

Can I get only Duolingo English courses?

Yes. For Courses, set Learning language code to en to see courses for learning English. Use Source language code to filter by the language a course is taught in, such as en for English.

Can I look up learners by display name?

No. Learner lookups need public usernames or public profile links.

Does it return followers, following lists, or user reviews?

No. It does not return follower or following lists, learner cohort rankings, or Duolingo user reviews.

Does it return course descriptions?

No. Course rows include public catalog details, such as titles, language codes, learner counts, and release phase. Course page descriptions are not included. Vocabulary rows return the available words and phrases from one selected course, with translations, skills, and units.

Does a failed lookup mean a learner or course was deleted?

No. A failed lookup does not prove that anything was removed. A record counts as missing only after a full, successful scan.

Can I continue a large run that stopped early?

Yes. Enter the earlier run ID or dataset ID in Continue collection from. Keep the same result type and lookup settings, and the run picks up from its saved progress.

How do I track changes over time?

Run the Actor again with the same lookup settings. Each row's changeType field shows how it compares with saved history. Use the same Monitoring campaign name in each run to share history. Leave it blank to keep each lookup's history separate.

How many results can one run return?

There is no fixed maximum. Leave Maximum results blank to collect all available results until the source has no more. Set a number to stop earlier.

What am I charged for?

You are charged for each successful row saved to the dataset, as listed in Pricing.

Is this the official Duolingo app or website?

No. This is an independent Actor that reads public Duolingo data. You do not need a Duolingo account or sign-in to run it.
