| Measurement | Before | After |

Review the largest image and scripts with the site owner. These lab results identify signals, not a confirmed cause.
From raw measurement
to a useful handoff.
Lighthouse gives you the measurement. Site Signal helps you prepare the client-facing explanation.
Bring your own evidence
Export a Lighthouse JSON file or a PageSpeed Insights API response. Import it from your computer. The app does not scan your client’s site.
Add your judgment
Choose your agency and client names, edit the summary, and turn findings into prioritized actions. Compare a second compatible run when you have one.
Export the report
Download a standalone HTML report or use your browser’s Print to PDF. Keep an editable project file for the next review.
Your report should
make the next step obvious.
A performance score alone leaves a client asking what to do with it. Put the observations, limitations and next actions in one readable document.
Site Signal is built for the handoff: editable commentary, client branding and a comparison that checks whether the measurements belong together.

Before you buy.
Does it fix my website or run audits?
No. It organizes measurements you already have. You run Lighthouse or PageSpeed separately, review the findings, and decide what changes are appropriate.
Is this an AI service or a hosted dashboard?
No. This is downloadable software. Report processing runs in your browser, with no telemetry, cloud account, AI API bill or server subscription. The store separately handles your purchase details.
Can I use it for client work?
Yes. One agency or freelancer may create and deliver reports for their clients. You may set your agency name, client name and report title. Custom logos and color themes are not included in this version. You may not resell or redistribute the underlying toolkit. See the included license.
Can I compare any two reports?
The tool checks the URL, device and audit settings. Incompatible runs are identified so you do not accidentally present unlike measurements as improvement. Lab results are not real-user field data or proof of business impact.
What computer do I need?
A desktop browser that supports local file imports and printing. Chrome or Edge on a computer is the recommended workflow. The sample can also be read on a phone.
How do delivery and support work?
When the store is active, it provides the ZIP automatically after successful payment. Unzip it and open index.html. Setup guidance and the license are included. Personalized site analysis and implementation are not included.
The seller’s support contact will be shown at checkout before purchase.
