FixMyCWV

What is FixMyCWV?

FixMyCWV is a Core Web Vitals audit tool that analyzes a website and returns code-level recommendations for fixing LCP, INP, and CLS issues. Its stated purpose is to help developers identify what is slowing a page down and understand what to change in the codebase or stack.

The product is positioned as a field audit, which means it is meant to reflect real-user performance rather than only lab conditions. According to the page, it also works from the user’s region, can bypass bot protection, and includes analysis of a Google Tag Manager container when relevant.

Key Features

• Core Web Vitals audit for LCP, INP, and CLS — the report focuses on the three metrics called out on the page, which helps teams target the specific causes of performance failures.
• Code-level fix recommendations — instead of only identifying symptoms, the audit aims to tell a developer what to change in the code.
• Estimated fix cost — the page says the report includes an estimate of the effort or cost to implement the fixes, which can help with prioritization.
• One-click sharing — the audit can be shared directly, which is useful when sending findings to developers or teammates.
• Tested from your users’ region — the audit is performed from the region associated with your users, which can surface region-specific performance behavior.
• Bypasses bot protection — the product states it can audit sites even when bot protection is enabled, which may matter for protected production environments.
• GTM container analysis — it includes analysis of Google Tag Manager container setup, suggesting it can inspect tag-related performance impact.
• Works across common site stacks — the page lists Next.js, WordPress, Shopify, and Webflow as supported environments.

How to Use FixMyCWV

A typical workflow starts by entering a site and running the first audit, which the page says is free. After the audit completes, you review the report to see which Core Web Vitals are failing, what code-level changes are recommended, and how much the fixes are estimated to cost.

From there, the report can be shared with a developer or team member so the findings can be acted on without translating the results into a separate document.

Use Cases

• Developer triage for Core Web Vitals failures — a developer can use the audit to identify which parts of a page are likely contributing to poor LCP, INP, or CLS performance.
• Performance reviews for production sites — teams can run an audit on a live site to understand issues in the environment users actually experience.
• Investigating sites behind bot protection — if a site blocks many automated tools, the product is intended to still collect audit data.
• Prioritizing fixes before implementation — the estimated fix cost can help teams decide which performance issues are worth addressing first.
• Sharing findings with non-specialists — the one-click sharing workflow can help when a marketer, founder, or project manager needs to forward the report to a developer.

FAQ

Does FixMyCWV analyze real-user performance or lab-only results?
The page describes it as a field audit, which indicates it is intended to reflect real-user conditions rather than only synthetic testing.

Which Core Web Vitals does it focus on?
The page explicitly mentions LCP, INP, and CLS.

Can it work on sites with bot protection?
Yes, the page says it bypasses bot protection.

What platforms does it work with?
The page lists Next.js, WordPress, Shopify, and Webflow.

Is pricing available?
The page says the first audit is free and then the product is pay-per-use, but it does not provide a price on the source page.

Alternatives

• Google PageSpeed Insights — useful for Core Web Vitals diagnosis, but it is more of a general performance analysis tool and does not present itself as a code-level fix planner.
• Lighthouse — a standard browser-based performance audit tool that is often used by developers, though it typically requires users to interpret findings themselves.
• WebPageTest — offers detailed performance testing and waterfall analysis, which can complement or substitute for audit workflows focused on diagnosing page speed issues.
• Other CWV consulting or monitoring services — agencies and performance platforms may help with diagnosis and remediation, but they differ in whether they produce an automated report versus hands-on support.
