It started with a simple itch. Two, actually. My love for sim racing and my curiosity about building apps without traditional coding. That itch turned into a real, working product.
Meet LapTimer. It’s live. You can use it right now. (early access request)
The problem it solves is straightforward. Simracers want to compare laptimes with friends, teammates, or the entire community. But we all play different games. You might be racing the McLaren 720s GT3 at Spa in Le Mans Ultimate while I’m doing the same combo in Assetto Corsa. Until now, there was no easy way to compare those times across simulators.
LapTimer fixes that. Post your laptimes, share them with specific people or everyone, and compare across games. Same car, same track, different simulator. Fully game agnostic. It is based on honesty, if racers want to share the telemetry to “proof” it, that is also possible.
The Challenge
Here’s the part that makes this project different. I built the entire app without writing a single line of code myself. Zero. Nada.
I used Claude Code with Opus 4.6 to generate every piece of the application. This approach is called Vibecoding. You describe what you want, guide the AI, and it writes the code for you. The skill is in knowing what to ask for and how to steer the output.
The result? A fully functional web app that users can sign up for, post times, filter by car and track, and see how they compare to others.
Why This Matters
I’ve spent years building websites and apps the traditional way. PHP, MySQL, Bootstrap, the whole stack. I still love that approach for certain projects. But this challenge is about something else entirely.
Can you build something useful without touching code? Can you move faster? Can you ship a real product by pairing your domain knowledge with AI?
The answer is yes. And the proof is live at simracevault.com/LapTimer.
If you’re into sim racing, app building, or just curious about what’s possible with AI-assisted development, check out LapTimer and stay tuned. More features are on the way.
