Lighthouse alternatives for real-world performance

Lighthouse is a useful starting point.

But if you’re relying on it to understand how your site actually performs for real users, it falls short.

PerfLeaf is built as a real-world Lighthouse alternative. It combines lab data, field data, and ongoing monitoring so you can see what matters in production, not just in a synthetic audit.

Measure real performance. Track trends. Fix what actually impacts users.

Why Lighthouse isn’t enough on its own#

Lighthouse runs controlled, synthetic tests. That’s helpful early on, but it misses what happens in reality.

Common problems teams hit with Lighthouse:

• Scores change wildly between runs
• Tests don’t reflect real devices, networks, or locations
• No visibility into performance over time
• No link between changes and real user impact
• Easy to “game” without genuinely improving UX

Lighthouse tells you how your site might perform in a lab.

PerfLeaf shows you how it actually performs in the wild.

A real-world alternative to Lighthouse#

PerfLeaf goes beyond single-run audits. It continuously monitors your site using real user data and repeatable testing, giving you a clear, stable picture of performance.

With PerfLeaf you get:

• Core Web Vitals from real users
• Trend-based performance tracking
• Change detection and regressions
• Actionable insights, not just scores

Instead of chasing green numbers, you focus on measurable improvement.

Built for modern performance teams#

PerfLeaf is designed for developers, agencies, and product teams who already understand Lighthouse, but need something more reliable.

Real user monitoring (RUM)#

See how real visitors experience your site across devices, networks, and locations.

Consistent lab testing#

Repeatable tests that reduce noise and highlight genuine changes.

Performance trends over time#

Understand whether performance is improving or regressing week-to-week, not just per deploy.

AI-assisted recommendations#

Get clear guidance on what to fix next and why it matters.

Accessibility and sustainability insights#

Performance doesn’t exist in isolation. PerfLeaf tracks accessibility and carbon impact alongside speed.

Use Lighthouse. Validate with PerfLeaf.#

You don’t need to abandon Lighthouse entirely. Many teams use it during development.

PerfLeaf answers the next questions Lighthouse can’t:

• Did this change actually improve real user experience?
• Are we getting faster or slowly regressing?
• Which pages are hurting our Core Web Vitals?
• What should we prioritise next?

PerfLeaf turns performance into something you can track, trust, and act on.

Who PerfLeaf is for#

• Teams frustrated by inconsistent Lighthouse scores
• Agencies that need ongoing performance reporting
• Developers who care about real users, not lab scores
• Product owners tracking SEO, UX, and sustainability together

If Lighthouse feels incomplete, PerfLeaf is the missing layer.
