Serverless function timeout limits prevent complex workloads

8/10 High

Vercel's serverless functions have a 10-second timeout limit on free tier and 60-300 second limits on paid plans, causing issues with complex payment processing, long-running agents, and AI workloads. Documentation claims 300 seconds but functions timeout at 60 seconds under load. Edge functions have even stricter limits and lack full Node.js compatibility.

The 5-minute request timeout is a ceiling, not a default. Any single request exceeding five minutes is terminated. This is not configurable. ML inference, large data exports, video processing, or complex report generation will hit this wall.
