Hey, I'm Holger

Why I Built This

I've been building, designing, and optimizing websites for a long time – sometimes professionally, sometimes just for fun. Over the years, one of the first things I always check on any site are the four Lighthouse scores: Performance, Accessibility, Best Practices, and SEO.

For my own projects, I've made it a personal goal to keep these scores as high as possible. There's something satisfying about seeing those green 90+ numbers.

But here's the thing: tracking performance across multiple websites over time has always been a pain. The tools that exist are either expensive, overly complex open-source projects that require self-hosting and maintenance, or free tools that limit you to a single URL.

The Idea

So I built LighthouseRobot for myself. I wanted a simple dashboard where I could add all my websites, see their Lighthouse scores at a glance, and track how they change over time – without paying a subscription or managing servers.

The leaderboard concept came naturally. When you have multiple sites, you start comparing them. Which one performs best? Which one needs attention? Turning it into a ranking made the whole thing more engaging – almost like a game.

Now I can check my scores anytime, anywhere – whether on my phone, at my desk, or while grabbing a coffee. Like right here for lighthouserobot.com:
