You write a standard solution, just like on LeetCode, and run it through the CLI. It identifies the problem by ID or title, executes your code against local test cases, and shows the result.
It currently supports around 1.4k problems and multiple languages, including Python, C++, Rust, Java, Go, TypeScript, Swift, and others.
The project is still an MVP. System design, SQL, and concurrency problems are not supported yet, but support for more problem types is planned.

There are already projects that can submit your solutions through the LeetCode API and return the results. But I don't really like that approach, so I decided to build an open set of tests that aims to match the quality of LeetCode's tests as closely as possible. This way, you can run everything locally, without needing for example, an internet connection.
I see the project being useful for its most straightforward purpose: testing your solutions locally on your own hardware, without any submission delays and even completely offline. Since the tests are open, people can also build different tools around them. For example vim extensions and other integrations. Ofc it's not that simple, we currently support about 1400 problems (out of 4000~, including premium), and not all topics are covered.
