Targeted input
Prompt exactly the panes you choose.
Focus one agent, select a team, or broadcast to the grid without accidental cross-pane input.
Open source local agent workspace
Every agent.
One workspace.
Launch, authenticate, isolate, monitor, and coordinate your entire CLI agent stack while every session stays a real terminal.

agents should not mean 10 windows.
GridBash gives agent-heavy development one shared control surface without flattening every session into the same context.
One process. Real terminals. No browser tabs and no fake log panes.
Built in Rust with Ratatui and portable-pty.
Built for parallel work that actually ships.
GridBash keeps every agent independent while giving you one fast place to direct the work.
Real PTYs
Your agents get actual terminals.
Full interactive sessions through ConPTY on Windows and native PTYs on Linux and macOS.
Worktrees
Parallel, not chaotic.
Give each pane an isolated repo-local checkout with one flag.
Manager goals
Let one agent coordinate the rest.
Manager goals review live pane output and route focused follow-ups across your current grid.
From zero to grid
Choose a build. Then let it rip.
No daemon, product account, or cloud workspace required.

The npm registry can temporarily trail a GitHub release. Check the current package version, or use the matching Windows, Linux, or macOS artifact from GitHub Releases.
