Developer bertieai shares a cost breakdown: syncing 100GB live to 1,000 concurrent users would cost $33,000/month on Supabase and $27,000 on Convex, but he replicated it for $9/month with a single Cloudflare Durable Object, detailing the approach in a thread. A striking example of how much margin managed BaaS pricing carries versus rolling your own sync layer.
