Show HN: I built speedmux, a libghostty-powered terminal multiplexer
- n89nanda 7mo agoI built speedmux to make parallel agent workflows manageable from one terminal interface. At a high level, the architecture is: 1. one terminal multiplexer process managing multiple concurrent sessions 2. per-session isolation so each agent/task can run independently 3. a persistent sidebar that tracks session state/activity without switching context 4. rendering/performance path powered by libghostty, which keeps interaction latency low even with multiple active sessions It’s written in Go, and a lot of it was vibe-coded with Codex.
