:owl: Duolingo Max for Free — $168/Year Unlocked in 30 Seconds

One browser extension. Every premium feature. No card, no trial, no catch.

Duolingo charges $168/year for features their own code hands over when asked nicely. Now you know.

One open-source extension patches Duolingo’s webpack files locally — when the site checks your subscription status, the response comes back “Max subscriber” before the page finishes loading. No servers involved, no account modifications, nothing stored anywhere. Your browser lies to Duolingo’s frontend. That’s it.

🔓 What Gets Unlocked — The $168/Year Breakdown

Duolingo Max normally runs $29.99/month or $167.99/year. Super Duolingo (the tier below) costs $83.99/year. This extension skips both paywalls entirely.

Feature Free Tier With Extension
Hearts 5 per session, wait or pay :infinity: Unlimited
Ads After every lesson Zero
Legendary Levels Locked behind gems Unlocked
Personalized Practice Limited Full access
Offline Access No Yes (Super feature)
Streak Repair Costs gems Free

:light_bulb: Trick: The extension patches at the browser level — Duolingo’s mobile app is untouched. Always use duolingo.com in your browser for Max features. The app still sees your real subscription status.

🛠️ Install It — Chrome, Firefox, or Any Chromium Browser

The extension is the same project — originally called “Duolingo Unlimited Hearts,” now renamed to Duolingo Max. Open-source, MPL-2.0 licensed on GitHub with 120+ stars.

Browser Best Install Method Link
Firefox :white_check_mark: Add-ons Store (kept updated) Duolingo Max — Firefox Add-ons
Chrome / Edge / Brave :warning: Manual install from GitHub Latest Release — GitHub

:warning: Chrome Web Store version is outdated and abandoned. The developer got rejected for “bypassing paywalls.” Don’t use the store version — it won’t get updates.

Chrome/Edge/Brave manual install (60 seconds):

  1. Go to the GitHub Releases page and download the latest .zip
  2. Open chrome://extensions in your browser
  3. Toggle Developer mode ON (top-right corner)
  4. Drag and drop the .zip file onto the extensions page
  5. Done. Open duolingo.com — Max features are active

Firefox install (30 seconds):

  1. Click this link → Add to Firefox
  2. Done. Open duolingo.com — Max features are active

:light_bulb: Trick: Firefox is the better choice here. The add-ons store version stays updated automatically. Chrome users need to manually re-download from GitHub whenever Duolingo pushes frontend changes that break the patch.

🗣️ Speaking Practice — The One Extra Step

Duolingo’s speaking exercises use the Web Speech API. Chrome has it built in — speaking practice works out of the box.

Firefox doesn’t ship Web Speech API. You need the developer’s companion extension:

Extension Link
Speech Recognition Polyfill Firefox Add-ons

Install it alongside the main extension. Now Firefox gets speaking practice too.

:light_bulb: Trick: If you only care about reading/writing/listening and don’t need speaking exercises, skip this entirely. The main extension works perfectly without it.

🚫 What NOT to Do — Common Mistakes
:cross_mark: Don’t Why
Install from Chrome Web Store Outdated, won’t receive updates — install from GitHub releases
Use the mobile app expecting Max Extension only patches the website, not the app
Log into Duolingo before installing Install the extension first, then visit the site
Ignore update notifications When Duolingo changes their frontend, the patch needs updating
Use this on public/shared computers Developer mode + sideloaded extensions raise flags for admins
⏳ How Long Will This Work?

Realistic talk. The developer has publicly stated maintenance continues through approximately March 2026. The extension patches Duolingo’s webpack JavaScript bundles — so it works until Duolingo restructures how their frontend loads subscription data.

Signal Status
GitHub activity Active, open-source, community contributions accepted
Firefox Add-ons Store Updated and maintained
Chrome Web Store :cross_mark: Abandoned (policy rejection)
Breaking risk Medium — Duolingo pushes frontend updates periodically
Recovery speed Fast — open-source means community can patch independently

The extension has survived multiple Duolingo frontend updates already. The developer built remote patch syncing — patches can update without re-downloading the whole extension.

:high_voltage: Quick Hits

Want Do
:fox: Easiest install → Firefox + Add-ons Store link
:laptop: Chrome/Edge/Brave → GitHub Releases + Developer Mode
:speaking_head: Speaking on Firefox → Add Speech Recognition Polyfill
:mobile_phone: Mobile access → Open duolingo.com in Firefox Android (extension works there too)
:wrench: Source code → GitHub repo (MPL-2.0)

$168/year. Or one browser extension and 30 seconds. The owl doesn’t need to know.
