Introduction
Vidar is a verification and alt-detection system for Discord. This is everything you need to install it, tune it, and understand how it decides.
What Vidar does
When someone joins your server, Vidar sends them a private verification link. They open a secure checkpoint, authorize with Discord, and Vidar scores the account across four categories of evidence — network, device, account, and links to existing members. Clean accounts get your verified role automatically; suspicious ones are held for review or blocked.
Core capabilities
- Alt & ban-evasion detection using privacy-respecting fingerprints and hashed network identifiers.
- VPN, proxy, and Tor intelligence from a live IP reputation provider.
- Explainable scoring — every verdict lists the exact signals and weights.
- Raid protection that ignores small organic join waves by design.
- A web dashboard for roles, thresholds, network policy, and raid tuning.
How the pieces fit
Vidar has two runtime halves that share one database. The bot handles Discord events — greeting joiners, sending verification links, and watching for raids. The web app hosts the checkpoint, the detection API, and the dashboard, and assigns roles through Discord's API. Neither stores raw IP addresses.
