I kept running lsof -i :PORT repeatedly to check what was alive locally. Eventually I wrote a small tool around it and it turned into this.

How it works: - One lsof / netstat call maps all listening processes - 100+ ports scanned in parallel via TCP connect, 150ms timeout each - HTTP fingerprinting reads response headers to identify frameworks (Spring Boot, Express, Django, etc.) - Filesystem detection reads package.json, pom.xml, go.mod, Cargo.toml from the process working directory to get the actual project name - Redis gets a PING/PONG health check, Postgres gets a connection handshake - Results pushed to the browser via WebSocket every few seconds

First scan: ~800ms. Subsequent scans: ~300-400ms. Memory: ~55MB RSS.

Detects 40+ services including databases, queues, monitoring tools, and AI runtimes (Ollama).

Single file UI, no build step, no bundler. Just HTML/CSS/JS served by Express.

I've been looking for the perfect tmux replacement.

Something powerful and scriptable, but usable without memorizing dozens of keybindings.

Something that supports persistent remote sessions that I can jump into from anywhere, but not so terrible to use from my phone.

Turns out, tmux was all I needed. It just needed a better UX, not a replacement.

That's why I'm building tmuxy.

tmuxy is a GUI that wraps tmux into a web and desktop app.

How it works: A Rust backend connects to tmux through control mode (one of tmux’s hidden gems surprisingly few people seem to know about) and streams state updates to a React frontend via SSE, or Tauri IPC on the desktop version.

Besides the improved UX, being web-based allows it to support all kinds of fancy stuff like image rendering, markdown previews, pane groups, and floating panes, while under the hood it's still tmux.

It's early stage. Live demo here: https://tmuxy.sh
