Preloop

Overview

Preloop is a Rust-based reimplementation of GitHub Actions designed to execute workflows locally or in self-hosted environments. It provides an isolated microVM runtime for each job, ensuring secure and reproducible execution. By leveraging Rust's performance and safety, Preloop aims to offer a faster and more reliable alternative to the standard GitHub Actions runner, particularly for developers who need to test workflows before pushing or who prefer self-hosted CI/CD solutions.
