The problem
The initial platform relied on unlisted YouTube videos, which made it easy for users to download and redistribute paid content.
The solution
I moved content to Cloudflare R2 and wired up a streaming flow that serves videos through signed, time-limited URLs. Combined with Next.js and Supabase auth, this locked down access without making playback fragile.
Technical decisions
Next.js handled the app shell and server-side rendering of critical pages. Supabase simplified auth and relational data. Cloudflare R2 was chosen for its S3-compatible APIs and cost-effective storage close to the edge.
What I learned
I gained a deeper understanding of building secure yet user-friendly media pipelines, especially around balancing DRM-like constraints with realistic implementation effort.
