New blog post! Whop powers thousands of creators and communities. When big influencers (millions of subscribers) brought their communities, real-time features—chat, notifications, feeds—it pushed Postgres to the edge. The DB was the bottleneck killing Whop’s scaling efforts.

Agentic traces contain perfect info about agent behavior with every plan, action, and retry. But it’s lost in a sea of JSON.
So we built AgentPrism: open source React components that turn traces into visual diagrams for debugging agents. Plug in OpenTelemetry data and see your agent’s process.
