Code Fixer

Code Fixer takes an error message — from Search Console, Lighthouse, a validator or the console — and gives you a diagnosis, severity, a solution with fixed code, an explanation and prevention advice. Built for vibe coders: you paste the error, the tool explains and fixes.

The analysis is AI advice based on what you paste — nothing is fetched or executed. Two things to know about the current version: the charge is 30 credits with no price display or confirmation dialog (recorded as "code-fixer" in your credit history), and if the run fails, no error message appears — simply nothing happens. The charge is auto-refunded server-side on failure, so a silent outcome costs you nothing.

Who this tool is for

Anyone building with AI tools who hits error messages they do not fully understand — and wants the fix explained, not just pasted.

Prerequisites

How to use it

  1. Pick an error type, or let the quick buttons fill in an example to replace.
  2. Paste your error message, ideally with the surrounding code.
  3. Analyze, and read the diagnosis before copying the fixed code.
  4. Read the prevention advice — that is where the learning lives.
