IRC Channel and Topic Search

Communication, Network & Web, Search

Free
No Download/Install required
No registration

Simple but effective tool to search for an IRC channel, on more than 500 IRC networks, on any topic: Netsplit.de functions as a specialized search engine and statistical aggregator for Internet Relay Chat (IRC) networks. It indexes thousands of channels across major networks like Libera.Chat, OFTC, and EFnet, providing real-time data on user counts, channel topics, and historical activity trends.

By crawling decentralized servers, the platform enables the discovery of active technical communities and niche support rooms that are otherwise opaque to standard web searches. The service also tracks global network metrics, including server health and total user populations, to assist in identifying stable communication nodes for professional collaboration and data exchange.

Note: if you have no IRC client and just want to text, you can use our free online tool to chat on the IRC without any install or registration: IRC Free Client

Disciplines: Software engineering, Open source communities, Electronics, Amateur radio.

Free alternative to Discord server lists, Slack communities.

IRC Channel and Topic Search compared with Discord server lists (typical) and Slack communities (typical)
IRC Channel and Topic Search (Netsplit.de)	Discord server lists (typical)	Slack communities (typical)
Discovery and listing: Netsplit.de is a third-party index of IRC networks and their channels. You do not need to connect to an IRC network to use it, and it also tracks topic changes and user counts.	Discovery and listing: Checked member: the built-in Server Discovery of Discord. Only servers that qualify and are switched on by their administrators appear there, so it is a curated showcase and not an index of every server.
Listing conditions: A channel is listed unless its operators set mode s. On Libera.Chat the default for new channels is unset, so they are listed, and channels with mode s are hidden from the public lists.	Listing conditions: Discord Server Discovery asks for at least 1,000 members, a server age of at least 8 weeks, a minimum level of activity that is not published, clean names and descriptions, and the 2FA requirement for moderation. Small technical groups usually fall below the member threshold.
History and retention: The service records topic changes and user counts for the channels it indexes, which lets you judge whether a channel is still active before you join.		History and retention: A free Slack workspace is limited to the most recent 90 days of message and file history, and search results cover only that window. Data older than one year is deleted.
Operator control: Channel operators decide whether a channel is visible, through the channel mode. The index itself is run by a third party and not by the network.	Operator control: Only users with the Manage Server or Administrator permission can enable or disable Server Discovery, and the server must first be a Community server.
