Docker vs Firejail: The Verdict

⚡ Summary:

Docker: Docker is an open platform for developing, shipping, and running applications. It allows developers to package applications into containers—standardized executable components combining application source code with the operating system (OS) libraries and dependencies required to run that code in any environment.

Firejail: Firejail is an open source SUID sandbox program for Linux. It uses Linux namespaces and seccomp-bpf to restrict the running environment of untrusted applications. Firejail aims to provide easy-to-use application sandboxing on Linux, allowing untrusted applications to run safely while limiting their access to the rest of the system.

Both tools serve their respective audiences. Compare the features, pricing, and user ratings above to determine which best fits your needs.
