Vercel timeout rescue

Vercel serverless functions keep timing out

Vercel serverless functions have a 10-second limit on hobby plans and 60 seconds on pro. AI-built apps often exceed this during database queries, file processing, or external API calls.

What is probably broken

Your app works locally but Vercel functions timeout during database operations or long-running tasks.

What production should look like

The app running on infrastructure with no execution time limits and stable long-running processes.

STEP 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.

STEP 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.

STEP 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.
