Best terminal IRC clients in 2026: WeeChat, Irssi and the minimalists

Terminal clients are why IRC never needed to be rescued: they run anywhere, script everything, and parked in a tmux session on a server they solve persistence with no extra software at all. The field splits cleanly into two veterans and a generation of minimalists, and the right choice is mostly a question of how much client you want to operate.

At a glance #

Client	Written in	Scripting	Status	Best for
WeeChat	C	Python, Perl, Lua, more	Very active — 4.9.4, July 2026	Power users, relay setups
Irssi	C	Perl	Dormant since 2023, rock-solid	tmux lifers
senpai	Go	none	Active	soju bouncer users
tiny	Rust	none	Slow but alive	Config-file minimalists
catgirl	C	none	Glacial	The truly ascetic

WeeChat — the power tool #

The most capable IRC client in existence, terminal or otherwise: WeeChat is scriptable in half a dozen languages, buffers for everything, and a relay protocol that lets mobile and web frontends attach to your always-running instance — many people run WeeChat as their bouncer and never install another piece of IRC software. The learning curve is real; so is the ceiling.

One current note: run 4.9.4 or later. The July 2026 release fixed an authentication bypass in the relay plugin and a path traversal in the logger — exactly the components a long-running setup exposes. Update, then forget about it.

Irssi — the classic #

For twenty years, Irssi was what "terminal IRC client" meant: lean, Perl-scriptable, and so finished that its last release was in 2023 without anyone particularly minding. irssi in tmux on a cheap VPS, attach from anywhere — the poor man's bouncer remains one of computing's great stable equilibria. Choose it over WeeChat when you want a client you configure once and never think about again.

The minimalists #

The newer generation assumes the bouncer does the remembering, and the client should do less, better.

senpai #

goguma's desk-bound sibling, senpai (Go) is written for soju and speaks IRCv3 chathistory natively, so scrollback and read state just work. The best terminal companion to a modern bouncer.

Download: sr.ht/~delthas/senpai — free; packaged in most distros.

tiny #

Small, pleasant and TOML-configured, tiny (Rust) does exactly what its name promises. Releases are rare, but the repo breathes.

Download: GitHub — free; cargo install tiny.

catgirl #

Rounding off the ascetic end, catgirl (C) has no scripting, no DCC, and barely any configuration. Quite deliberately.

Download: git.causal.agency/catgirl — free; in Homebrew and several distros.

Recommendations #

• Want the most client: WeeChat — and use its relay instead of a bouncer.
• Want the least ceremony: Irssi in tmux, unchanged since forever, because it never needed changing.
• Run soju already: senpai.
• Allergic to both Perl and Python: tiny.

All of them do TLS and SASL properly — register your nick and set both on day one.
