WHAT IT DOES
What does it do?
kern runs generated code in a fresh container based on an OCI image and discards the container afterward. By default, it blocks network access and limits memory, process count, and execution time. Its API is available from Python and Node, and it also provides an MCP server and LangChain tools.

EDITOR'S NOTE
Why did it stand out?
It focuses on the moment an agent's code needs to run. Each run uses a fresh container, while files can be carried between runs and failure causes distinguished, helping determine what to do next from the result.
