Brilliant alternatives: 5 open-source picks
Brilliant costs $30/mo — $360 a year. These 5 alternatives replace it for $0, led by Moodle, Oppia and eXeLearning. All 5 are open source. License, stars and last commit checked by hand on 2026-08-29. No trials, no crippled tiers.
Hosts authored activities, quizzes and progress, although the actual interactive pedagogy still has to come from you.
licenseGPL-3.0+
runsyour server
installInstall PHP and a supported database and web server, create the moodledata directory, then run the web installer and cron
dataCourse records and activity data live in a relational database; uploaded files, caches and sessions live under moodledata, with .mbz course backups
the catch vs BrilliantIt is an LMS shell rather than Brilliant's interactive pedagogy, so the author must build the lessons, feedback and activities from scratch.
setupWeb hosting, PHP and database compatibility, cron, security hardening and upgrades all belong to the operator

Authors branching interactive explorations that respond to wrong answers instead of merely displaying the solution.

runsyour machine or their cloud
installUse Oppia.org directly, or deploy the Python and Angular application on a Google App Engine-style stack
dataExplorations, skills, stories, questions and learner progress live in Oppia's hosted Google Cloud Datastore and Storage, or the equivalent self-hosted deployment
the catch vs BrilliantCreating responsive branches is manual, and the result does not match Brilliant's broad authored catalog or production-quality interactive visuals.
setupNone on Oppia.org; self-hosting is a developer-grade Google App Engine deployment

setup✓ installs clean
the catch vs BrilliantIt is an authoring and export tool, not Brilliant's polished ready-made adaptive STEM curriculum, guided learning path or motivation system.

how to choose a Brilliant alternative
Easiest to get running
eXeLearning — a one-click install, no server to maintain.
Most proven
Anki, with 22,000 GitHub stars — the largest community of the 5, which usually means more answers when something breaks.
Works on your phone
Moodle has a mobile app on iOS and Android.
Needs real ops to self-host
Moodle is capable but expects someone to run a server, updates and backups. Budget for that before choosing it.
what you give up by leaving Brilliant
- expert curriculum, interactive problem library, pedagogy, apps, and content rights
- licensed course catalog
- expert curriculum
- human feedback
- large learner network and certification
None of the picks above covers all of it. The full verdict says which gaps matter.

why people still pay for Brilliant
People still pay for Brilliant because the learning loop is buildable, while trusted curriculum, instructors, feedback, credentials, and community are not. The recurring cost buys curriculum quality, assessment validity, content rights, spaced-repetition tuning, speech models, sync, moderation, and support, not just the visible interface. If none of that applies to you, any pick above saves $360 a year.
