Lithos

Lithos strictly provides only core containerization and supervision features, avoiding unnecessary bloat like image downloaders or network APIs, as emphasized in the README.

Written in Rust, Lithos ensures memory safety and has zero runtime dependencies, resulting in a minimal footprint and reliable performance for isolated environments.

It includes immediate restart of failing processes with rate limiting, ensuring high availability without system overload, as highlighted in the features list.

Lithos can be upgraded without affecting running child processes, reducing downtime during updates, which is a key feature mentioned in the documentation.
