CodeChef is a not-for-profit educational initiative started by Directi more than a decade ago. We started with a dream of seeing an Indian team winning a gold medal at the ACM ICPC World Finals. In its quest for the same, CodeChef has built a self-driven community of the world's best programmers. Today more than 1.3 million competitive programmers from 180+ countries learn from CodeChef. CodeChef has been hosting monthly programming contests regularly for 10 years now. Its platform has assessed 92 million+ code submissions to date, and over 30000 organizations are being impacted by CodeCheffers worldwide. It also organizes SnackDown - one of the world's largest global programming competition whose last edition drew participation from 140+ countries. Since 2017, CodeChef has started providing India's only industry-ready certification in Data Structures and Algorithms, and 1800+ programmers have been certified under the same.

KohaKoha is recommended for public libraries, academic institutions, and special libraries that require a flexible and scalable system. It is particularly beneficial for libraries with limited budgets since it eliminates licensing fees and allows for custom development and integration with existing systems.
Koha might be a bit more popular than Codechef. We know about 10 links to it since March 2021 and only 7 links to Codechef. We are tracking product recommendations and mentions on various public social media platforms and blogs. They can help you identify which product is more popular and what people think of it.

We are lending stuff like books, laptops, beer benches (hallo freunde) and other stuff. Currently we are using librebooking, but obviously this is not the intended use case. Stuff like maximum lended objects is relevant to us. I saw koha which looks promising, but as it is intended for a library it has any features we dont need, such as acquistion. Any ideas?

On the harder side of the world, there are entire open source products like Koha (https://koha-community.org) and Evergreen (https://evergreen-ils.org) that are capable of running large libraries, but require installation and systems maintenance. On the easier, something like Librarycat (https://www.librarycat.org) might work fine for your needs (and if you end up using it, lmk...the developer is a friend) or... Source: over 3 years ago
