Fix · Vercel and deploying

Build ran out of memory or took too long on Vercel

Not checked against the vendor's current screens

What you may see

The build stops with a memory message or is killed
The build used to pass and got slower

Most likely cause

The build handles too much at once: very large images or pages, thousands of pages built together, or a dependency doing heavy work.

Check first (about two minutes)

Look at the log: which step was running when it stopped?
Count the pages built at once (a build log lists them).

Prompt language

You are a patient senior engineer who deploys websites on Vercel every day and explains it to people who are not developers. I am not a developer, so explain every step in plain words and tell me exactly which button, menu or command you mean. If you are not sure about something, say so; do not guess.

Menu and button names change over time. If you cannot find a button or page I mention, say so and tell me what to look for instead of guessing.

THE PROBLEM

MOST LIKELY CAUSE
The build handles too much at once: very large images or pages, thousands of pages built together, or a dependency doing heavy work.

DO THESE STEPS, IN THIS ORDER
1. Find the heavy step in the build log and what it is building.
2. Reduce the work: build fewer pages at build time (generate the rest on first visit), shrink or remove huge images from the build, and remove unused packages.
3. Only if needed, explain the safe way to raise Node memory for the build.
Stop and tell me if what you see does not match a step. Do not skip ahead.

CHECK THAT IT WORKED
- The build finishes in a normal time and the deployment is Ready.
Tell me exactly what I should see on the screen when it works.

DO NOT CHANGE
- Do not delete pages or features to pass the build.
- Anything I did not ask about: the design, the text, other pages, other settings or the data.
- Do not delete files, data or branches, do not reset or force-push, and do not rewrite history, unless you first show me exactly what would be lost and I say yes.
- Do not paste, print or ask me to paste a password or secret key into this chat. If one is needed, tell me which settings page of the right service to store it in.

WHEN YOU FINISH
Explain in simple words what you changed (file by file or setting by setting), why you changed it, and how I can undo it.

Paste it into Claude, ChatGPT, Gemini or Cursor, then follow what it says.

After you tried it, did it work?

Do not do this

Do not upgrade the plan before trying the cheap fixes.
Do not delete pages or features to pass the build.
