Learn what Robust IRC is, how its Raft-based architecture eliminates netsplits, and how to self-host this open-source IRC network software.
RobustIRC is an open-source IRC network implementation built by developer Michael Stapelberg to solve one of IRC's longest-standing reliability problems: netsplits. Instead of linking independent IRC servers together in a traditional federation, RobustIRC runs a cluster of nodes that share consensus-backed state using the Raft algorithm, so the network keeps functioning even when individual nodes fail or restart.
The project is implemented in Go and is fully open source, distributed through GitHub. It is aimed at technically sophisticated users and IRC network operators rather than mainstream chat users, and standard IRC clients connect through a bridge component without needing special support.
RobustIRC's core feature is its Raft-based distributed architecture, which allows multiple server nodes to agree on network state and tolerate node failures without causing netsplits or duplicate nickname collisions. This also enables rolling upgrades and maintenance restarts that are largely invisible to connected users.
The project preserves client sessions transparently across brief connectivity interruptions and works with unmodified, standard IRC clients via a bridge, meaning operators do not need users to adopt any special software to benefit from the added resiliency.
RobustIRC is free and open source with no commercial pricing tiers. It is self-hosted software intended for network operators and developers comfortable running and maintaining their own infrastructure.
RobustIRC is an open-source, fault-tolerant IRC network implementation that uses the Raft consensus algorithm to eliminate netsplits.
RobustIRC was created by developer Michael Stapelberg, also known for open-source projects such as the i3 window manager.
Yes, RobustIRC is free and open-source software with no commercial pricing.
RobustIRC is implemented in Go.
Yes, standard IRC clients can connect to a RobustIRC network through its bridge component without special support.
It uses the Raft consensus algorithm so multiple server nodes share agreed-upon network state, avoiding the divided views that cause traditional netsplits.
No, it is aimed at IRC network operators and technically sophisticated self-hosters rather than casual end users.
RobustIRC is hosted on GitHub under the RobustIRC organization.
