Site Up. Costs Down: Optimizing OpenClaw’s 1M Weekly Active Users

The ClawHub application, a skill repository for the OpenClaw AI project, scaled to one million weekly active users, resulting in high infrastructure costs and 9TB of daily database traffic. Built on the Convex backend-as-a-service, the initial "vibe-coded" architecture was inefficient, leading to excessive bandwidth usage. Key optimization strategies included replacing real-time reactive subscriptions with one-shot fetches for static catalog pages to reduce unnecessary query re-executions. This architectural shift significantly cut down on data transfer, bringing daily traffic down from 9TB to 600GB by improving how the application handles queries at scale.
