I run 3-5 AI coding agents in parallel (Claude Code, Codex, Gemini) and the bottleneck was never the agents, it was managing them. Switching panes, losing track of which agent had which role, re-typing the same setup every time.

Seshions is a terminal UI that gives you one dashboard to launch, route prompts to, and monitor parallel coding agents via tmux.

What makes it different from other tmux session managers:

- Blueprints: define a multi-agent team once (planner, builder, reviewer, etc.) and launch the whole group in one action - Orchestration: dispatch a prompt to a single role, or broadcast to every agent in a group — from one composer - Works across tools: Claude Code, Codex, Gemini CLI, OpenCode, or any custom shell command - One command: npx seshions@latest

Built with Bun + TypeScript. I would love to get feedback on the UX and what workflows you'd want supported.
