Feature checklists rarely decide anything. What decides it is the pricing metric, who has to write the tests, and which limitation you can live with.

Strengths
- Already installed in every Chrome browser — zero adoption cost.
- Covers performance, accessibility and SEO in one report.
- Lighthouse CI turns scores into enforceable build assertions.
- Human expert audits and assistive-technology user testing alongside the tooling.
- Legal and VPAT support for organisations under compliance pressure.
- Covers web, mobile and desktop applications.
Limitations
- Lab data from a synthetic environment, not what real users experience.
- Scores vary run to run, which makes strict thresholds frustrating.
- Accessibility coverage is the axe-core subset, not a full audit.
- Expensive, services-heavy engagement model.
- The UserWay overlay heritage is contentious — automated overlays are widely criticised by accessibility practitioners.
- Not a self-serve developer tool.
