The idea
Working with several command-line agents can mean opening terminals, arranging splits, and typing the same startup command repeatedly. AgentSwarm brings that setup into a dedicated VS Code sidebar: choose a layout and launch the terminals together.
See it in action
A quick look at launching a grid of agent terminals in VS Code.
Watch the AgentSwarm demo by JNP Creates on X.
Choose a grid. Get to work.
Pick a preset such as 1 × 2, 2 × 2, or 2 × 4, or adjust the rows and columns yourself. Each terminal opens in the editor grid so you can keep several sessions in view.
- Launch plain shells or enable a shared startup command for each terminal.
- Use the layout for coding agents, command-line tools, or regular shell sessions.
- Close the terminals launched by AgentSwarm with one command.
Behind the build
The extension is written in TypeScript. A sidebar provides the controls, while VS Code's extension APIs create the terminals and arrange the editor groups.
AgentSwarm handles the terminal setup. You choose what each session works on and how to coordinate the work. Startup commands run only when you enable that option.
