Vercel timeout rescue

Vercel serverless functions keep timing out

Walkthrough

1. 01

   Find the slow functions

   Identify which serverless functions are exceeding the time limit.

   • Check Vercel logs for timeout errors and execution duration.
   • Identify which database queries or external calls are slow.
   • Measure the actual execution time of each function locally.
2. 02

   Optimize or restructure

   Speed up the functions or move them to a different runtime.

   • Add database indexes to speed up slow queries.
   • Move long-running tasks to background jobs or webhooks.
   • If optimization is not enough, move to a VPS with no time limits.
3. 03

   Deploy to infrastructure without limits

   A VPS runs your code as long as it needs to.

   • Deploy the app on a VPS with a process manager.
   • Test the previously timing-out functions on the new server.
   • Monitor execution times and resource usage.
