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
- Signed-in account
- 30 credits per analysis — charged silently on click
- The error message (at least a few words); code, URL and context improve the answer
How to use it
- Pick an error type, or let the quick buttons fill in an example to replace.
- Paste your error message, ideally with the surrounding code.
- Analyze, and read the diagnosis before copying the fixed code.
- Read the prevention advice — that is where the learning lives.
How to read the result
- The diagnosis explains what the error actually means — read it even if you only want the fix.
- The fixed code is a suggestion: diff it against your own before pasting.
- The severity helps you prioritize when you have several errors.
Common errors
- Nothing happens after clicking: the run failed silently — the charge was auto-refunded; retry, and check the error message is complete.
- Generic answer: too little context — paste the code around the error, not just the message.
Limitations
- The tool does not run your code — the suggestion must be tested on your side.
- Auto-saves to your tool history, but no export.
- The charge appears as "code-fixer" in your credit history.
