Jeed is a fast Java and Kotlin execution and analysis toolkit. It compiles and safely executes Java and Kotlin code up to 100 times faster than using a container, allowing a small number of backend servers to easily support a large amount of interactive use.

Jeed can also perform a variety of analysis tasks, including linting (checkstyle and ktlint), cyclomatic complexity analysis, and language feature analysis (Java only currently). It also supports snippet mode, a relaxed Java and Kotlin syntax that allows top-level method definitions and loose code.
