Deep Dive: Switching from Brilliant to Oppia
Trade-offs, installation & data architecture
What you trade away
Creating responsive branches is manual, and the result does not match Brilliant's broad authored catalog or production-quality interactive visuals.
How to deploy Oppia
Use Oppia.org directly, or deploy the Python and Angular application on a Google App Engine-style stack
What it takes to run
None on Oppia.org; self-hosting is a developer-grade Google App Engine deployment
Where your data lives
Explorations, skills, stories, questions and learner progress live in Oppia's hosted Google Cloud Datastore and Storage, or the equivalent self-hosted deployment
Why fork Oppia instead of vibe-coding a Brilliant clone?
A consolation build is possible, but the paid product's decisive value sits outside a solo rebuild. For Brilliant, build interactive practice around user-authored math and science lessons. The hard boundary is expert curriculum, interactive problem library, pedagogy, apps, and content rights, plus content, pedagogy, and network.
