HOTS Hosts Lite is a free, open-source Windows app for viewing and managing the system hosts file (Fluent Design, dark/light theme).

CORE: real-time table view, live search, bulk paste, auto-backup (rotating archive), diff preview, import/export .txt/.csv.

DIAGNOSTICS: domain existence check, heuristic malware scanner (homoglyphs, punycode, typosquatting, suspicious TLDs).

BLOCKING: custom domain blocklist, hosts file lock (ACL deny-write), application firewall blocking, 3 switchable hosts profiles.

Also: 4 accent colors, 7 languages (EN/PL/FR/DE/ES/PT/RU), optional password protection, built-in update checker.

Free, GPLv3.

A lighter companion to the full HOTS Hosts, which adds parental-control blocklists, Cloudflare Family DNS, DNS-over-HTTPS blocking, VPN client blocking, System Restore integration, and a full privacy module.
