Score: 6.3/10 (Innovation: 6, Technical: 6, Documentation: 7, Utility: 6)

Blc is a macOS website blocker that uses system-native mechanisms (/etc/resolver, launchd, Python) to enforce scheduled blocking of domains and their subdomains. It stands out by avoiding browser extensions or VPNs, providing a lightweight, system-level DNS-based approach with a simple CLI and logging for pauses and unblocks.

Target audience: macOS users seeking self-control tools, productivity-focused developers
