Ergo

Ergo (formerly known as Oragono) is a modern IRC server written in Go. Its core design principles are:

• Being simple to set up and use
• Combining the features of an ircd, a services framework, and a bouncer (integrated account management, history storage, and bouncer functionality)
• Bleeding-edge IRCv3 support, suitable for use as an IRCv3 reference implementation
• High customizability via a rehashable (i.e., reloadable at runtime) YAML config

Ergo is a fork of the Ergonomadic IRC daemon.

Features:

• integrated services: NickServ for user accounts, ChanServ for channel registration, and HostServ for vanity hosts
• bouncer-like features: storing and replaying history, allowing multiple clients to use the same nickname
• native TLS/SSL support, including support for client certificates
• IRCv3 support
• yaml configuration
• updating server config and TLS certificates on-the-fly (rehashing)
• SASL authentication
• LDAP support
• supports multiple languages (you can also set a default language for your network)
• optional support for UTF-8 nick and channel names with RFC 8265 (PRECIS)
• advanced security and privacy features (support for requiring SASL for all logins, cloaking IPs, and running as a Tor hidden service)
• an extensible privilege system for IRC operators
• ident lookups for usernames
• automated client connection limits
• passwords stored with bcrypt
• UBAN, a unified ban system that can target IPs, networks, masks, and registered accounts (KLINE and DLINE are also supported)
• a focus on developing with specifications
