Score: 8.3/10 (Innovation: 8, Technical: 9, Documentation: 8, Utility: 8)

Preloop is a local, self-hosted GitHub Actions engine that runs workflows in hardware-isolated microVMs and implements the official runner protocol, allowing drop-in replacement. It offers a Rust-based runner that is significantly smaller and faster than the official one, with features like SSH/pause for debugging failed jobs and NDJSON event output for agent integration.

Target audience: DevOps engineers, backend developers, CI/CD platform teams
