FixMyCWV is a web-based Core Web Vitals audit tool that produces developer-focused recommendations for improving LCP, INP, and CLS. It works across many site stacks and claims to handle sites with bot protection.
What FixMyCWV does
FixMyCWV is a web-based Core Web Vitals audit tool that turns a URL into a technical performance report for developers. The homepage says it identifies what is slowing a page down and generates code-level recommendations for LCP, INP, and CLS issues.
The product is designed to work on many site types, including major CMS, ecommerce, and frontend stacks listed on the homepage. The site also states that audits are tested from the user's region, can bypass bot protection, and include an estimated fix cost and sharing workflow.
Core capabilities
Developer-oriented fixes
Returns code-level recommendations intended to tell a developer exactly what to change, rather than only describing the problem.
Bot-protection bypass
Uses a stealth browser and residential proxies so it can collect data from sites that use bot protection.
Field and lab signals
Combines field data and lab data, including Google PageSpeed Insights API and Chrome UX Report references in the privacy policy.
Broad platform coverage
Analyzes sites across a broad set of platforms and stacks listed on the homepage, including WordPress, Shopify, Next.js, React, Angular, and others.
Shareable reports
Includes one-click sharing according to the meta description, and the terms page says generated audit reports belong to the customer for use.
Common ways to use FixMyCWV
Diagnose a slow page
Use the service when a page is underperforming and you want a technical readout that points to the likely causes of Core Web Vitals failures.
Prepare a developer task list
Use it when you need implementation guidance you can hand to a developer, especially for LCP, INP, or CLS fixes.
Audit different stacks
Use it to audit sites built on platforms such as WordPress, Shopify, Next.js, React, or Angular without needing a platform-specific workflow.
Inspect protected sites
Use it when a site is behind bot protection and you still need performance data from a browser-based audit.
Share audit results
Use it when you want to share a report with teammates or clients rather than summarizing the findings manually.
