You don't need Next.js

I started ComfyDeploy as an open source project (GitHub) - a full stack app with Next.js doing all the heavy lifting for both frontend and backend. We had Drizzle + Server Actions making everything type-safe and neat. It was all good until things started hitting the fan: We received an unexpected $2,000 bill from Vercel due to high API usage from a single user Testing APIs became a nightmare, because we had a lof of server actions mixed with api routes. Build times got so slow it felt like watching paint dry. Local dev was brutal - every tiny change triggered a full SSR reload.
