About
The one-click website speed report. Paste any site's URL, and about 15 seconds later your inbox names the three things making it slow - the hero, the script, the pixel.
Features
- Problem
- Speed scores do not identify what to fix.
- How it works
- Analyzes a public URL and names three likely performance blockers in an emailed report.
- Result
- Recipients get an actionable shortlist rather than a 0–100 score.
- Why
- Each finding is tied to concrete evidence such as a file, byte size, or header.
- Problem
- Large above-the-fold assets can delay LCP.
- How it works
- Reads the LCP element and hero bytes during a mobile lab pass.
- Result
- Teams can pinpoint a heavy hero asset holding LCP.
- Why
- The report can identify the asset that must download before the largest paint completes.
- Problem
- Blocking assets and third parties obscure main-thread issues.
- How it works
- Lists render-blocking CSS and JavaScript and identifies third-party pixels.
- Result
- Teams can identify scripts and pixels competing for network or main-thread time.
- Why
- The report connects these resources to lab TBT findings.
- Problem
- Public-site diagnostics can overclaim infrastructure knowledge.
- How it works
- Labels results as mobile lab data and explicitly excludes items such as Redis, PHP workers, host plans, and databases.
- Result
- Findings have clear evidence boundaries.
- Why
- The service only reports what a public URL can prove.
- Problem
- Traditional audits may require access or installation.
- How it works
- Fetches a public URL without login, plugin, FTP, or installation.
- Result
- A report can be requested with minimal setup.
- Why
- The workflow uses one public mobile lab pass.
What makes it different
- Super easy and fast
