Before you choose
Check free access and trials
Check whether a tool offers a free plan or trial, and review the current terms before choosing a paid plan.
Compare the free plan with the paid starting point. Look at what the plan permits for pages, audits, sites, projects, reports, and integrations.
Match crawl and audit needs
The pages-per-crawl figure indicates the amount of a site a tool can examine in one crawl. Audit frequency shows how regularly checks may run.
Audit coverage describes the areas a tool reviews. Compare that coverage with the checks your site requires.
Choose a platform that fits
The list includes tools for web, API, Windows, macOS, Linux, and browser extensions. Verify that a tool supports the platform you need before choosing it.
If you need to connect the audit process to another system, check whether the tool provides an API or a native integration.
Review projects and reports
When you manage multiple web properties, compare how each tool supports sites or projects. Check how the tool handles project separation and audit history.
For reports that require your branding, review white-label support. Confirm native integrations when results must move into another service.
Check the licence when code matters
Lighthouse is listed as open source. If you need to read or change code, review the licence for the tool you are considering.
