Inspiration

Building a better car comparison website than Check24!

What it does

  • search and maintain a large database of vehicle offers
  • also process incoming offer updates from the car sharing providers

How we built it

  • first approach was to build it using typescript + postgres, but we got stuck with complicated sql errors
  • decided to make a new implementation from scratch using C++

Challenges we ran into

  • sql debugging without an ORM is difficult
  • debugging sql functions is even harder
  • you can easily get lost in debugging challenges without making progress towards a better score in the challenge

Accomplishments that we're proud of

  • implemented a working REST API in C++

What we learned

At first glance, things often seem easier to implement than they turn out to be in retrospect

What's next for Check42

Beat our old rival Check24 in the search comparison market!
