ModSeeker

What's New in v2.0

Launcher/Client Detection & Enforcement

The biggest addition in v2.0. ModSeeker can now detect which launcher a player is using through native OS-level inspection — not guesswork, not self-reported. Supports 15 launchers including Prism, MultiMC, CurseForge, Modrinth App, Lunar Client, Badlion, and more. Each launcher can be individually allowed or blocked via client-list.yml. Players on unapproved or unknown launchers are kicked automatically.

3-Layer Security Architecture

All verification is now split into three independent layers: - Layer 1 — Cryptographic challenge-response handshake (RSA-2048) - Layer 2 — Launcher detection & enforcement (new) - Layer 3 — Encrypted mod verification (RSA/AES-256 + HMAC integrity) Each layer works independently — disable one without weakening the others.

Discord Webhooks

Real-time Discord notifications for player joins, mod lists, blacklist violations, and verification failures. Just paste your webhook URL into config.yml.
