Show HN: Teemux – Zero-config log multiplexer with built-in MCP server

https://teemux.com/
8•gajus•4h ago
I started to use AI agents for coding and quickly ran into a frustrating limitation – there is no easy way to share my development environment logs with AI agents. So that's what is Teemux. A simple CLI program that aggregates logs, makes them available to you as a developer (in a pretty UI), and makes them available to your AI coding agents using MCP.

There is one implementation detail that I geek out about:

It is zero config and has built-in leader nomination for running the web server and MCP server. When you start one `teemux` instance, it starts web server, .. when you start second and third instances, they join the first server and start merging logs. If you were to kill the first instance, a new leader is nominated. This design allows to seamless add/remove nodes that share logs (a process that historically would have taken a central log aggregator).

A super quick demo:

npx teemux -- curl -N https://teemux.com/random-logs

Cool utility. Horrendous name.
gajus•1h ago
lowkey thought it is a genius name

tee (Unix command that splits output) + mux (multiplexer) = teemux

cap11235•56m ago
Pronounced tmux. That's a thing. A very related thing. A very well-known thing. It's a bad name. I do like the concept though (haven't tried using it yet).

Fair point

Couldn't coding agents just run `tail -f *`?
gajus•38m ago
That would require restarting your services to redirect their output. Fine for one-off scripts, but impractical when you have long-running processes and don't want to restart them every time an agent needs to read logs.

With teemux, a persistent MCP server gives multiple AI agents access to logs as needed—without interrupting your development flow.
