CometWeb
For agencies and web teams
Client site audits,
a clear fix order and before-and-after results.
Insight checks performance, SEO, accessibility, security and CO₂e, builds one priority list and shows what changed after you ship. Hand the result to your developer and your client without rewriting it.

How Insight works
From a site URL to a verified fix.
Check the site, set priorities, turn findings into tasks, then compare a later run after you ship.
Set priorities and tasks
Not every finding needs an immediate fix. Review impact and context, then turn findings into tasks to ship.
Verify the result
After you ship, run another analysis. Compare results and see which issues cleared and which still need work.

This is the report you get.
This is the public Insight report for cometweb.io. It opens without an account, so you can see the score, the priorities and the full document before you sign up.
- Overall score and five quality areas
- Findings with their source and priority
- Full report to download as a PDF
Measured on CometWeb's own domain.
Public, versioned methodology. See how each score and priority is calculated. Methodology v1.4
Who it's for
One tool. Several uses.
Agencies prepare client scope. Freelancers document fixes. Web teams check whether releases close the reported issues.
Web agencies
When you have many clients and want a clear starting point before every scope conversation.
- One artifact for agreeing the work scope
- Less manual report assembly
- Before-and-after result comparison
Already using Ahrefs, Screaming Frog or Lighthouse?
Research, analytics and tasks stay where they are. Insight adds the technical audit, one fix list, result history and a client report.
This describes a workflow split, not a list of built-in integrations.
- SEO research
- Measurement and standards
- Analytics
- Team delivery
Audit, priorities, re-test and reportWhat Insight checks
One run. One shared work order.
Performance, SEO, accessibility, security and CO₂e land on one priority list. Scope depends on your plan and scan type.

Case study
On our own site, one animation blocked the main thread. After the fix, Lighthouse went from 49 to 79.
cometweb.io homepage, our own site- 2.7–5.4 s 0.10–0.26 s
- TBT in the lab on mobile
- 49 79
- Lighthouse on mobile, median of four runs
- 69 87
- overall Insight score after five fixes*
Barely moved: LCP 3.9–4.1 s → 3.6–3.9 s. That is the next job.
* Both overall scores were recalculated with the model from 1 October 2026. The September reports, saved with the older model, showed different numbers.

Insight combines performance, SEO, accessibility, security and CO₂e in one run, then turns the findings into shared priorities and a retest. PSI and Lighthouse remain excellent performance tools. Insight does not replace Ahrefs or a pentest, and it does not certify WCAG.
Those tools go deep on one area. Insight helps with the next step: it turns many findings into one work order and tasks. After you ship, it re-checks the same scope, so the plan for a client lives in one place.
No. Automated analysis detects some accessibility issues, but it does not replace manual testing, an expert audit or a formal compliance assessment.
No. A public site URL is enough. You do not install a script or share admin access.
CometWeb is built by Maciej Zmitrukiewicz, who has been building websites since 2018. He tested Insight on his own site first and wrote up the before-and-after results in the cometweb.io case study. Questions sent to hello@cometweb.io are answered by the person who builds the product.
No. The seller is Maciej Zmitrukiewicz, a private individual without a Polish tax ID (NIP), so no VAT is added to the price and the sales document is a receipt. You see the total before you pay, and the receipt is then available in the Insight billing portal.

Free gives you one project and one Standard audit a month, so you can judge the first result. History and before-and-after comparison are on paid plans.
