Run Pi in Agentastic
A compact, extensible coding-agent harness that keeps its native terminal interface inside Agentastic.
What Agentastic adds
Give every task its own worktree, branch, or container.
Keep Pi's real CLI and your existing configuration.
Inspect the diff, run code review, test, and open a pull request.
Launch Pi
- Install the official CLI and sign in with your existing provider account.
- Open a repository in Agentastic. The connection is discovered from your PATH.
- Open Agent Home, choose Pi, describe the task, and select worktree, local, container, cloud, or remote mode.
Every run gets its own git worktree, so three tasks can share a repository without sharing a branch or a build directory.
What Pi supports
- Launch from a task description: supported
Type the task in Agent Home and Agentastic hands it to pi at launch, so the run starts from your prompt instead of an empty session.
- Unattended runs: not supported
Pi confirms its actions as it goes, so plan on watching the run rather than scheduling it.
- Plan before editing: not supported
Agentastic keeps plan mode out of the picker for Pi rather than emulating it, so runs begin with edits.
- Resume a session: supported
Reopen the last Pi session for a worktree and keep its history — useful when reviewing the diff turns up one more change.
- Structured chat: not supported
Pi runs in its own terminal UI inside Agentastic; it does not expose a protocol Agentastic can render as a structured chat.
- Code review: not supported
Pi writes the change; pair it with a review-capable agent for the pass before merge.
Agentastic reads these from Pi's own CLI rather than emulating them, and modes it does not support stay out of the picker. The provider reference lists the exact flags for each launch, and how to compare coding agents covers what changes when you switch harnesses.
Pi questions
Is there a GUI for Pi?
Yes. Agentastic runs the real Pi CLI (pi) in a native Mac workspace with a git worktree, terminal, diff view, and code review for each task.
How do I run multiple Pi sessions in parallel?
Start each task from Agent Home in worktree mode. Agentastic gives every run its own git worktree and terminal, so several Pi sessions can work in one repository without editing the same files.
How do I install Pi?
Run npm install -g @mariozechner/pi-coding-agent, then sign in the way Pi's documentation describes. Agentastic finds the pi command on your PATH when you open a repository.
Does Agentastic charge for Pi?
No. Agentastic is free and does not proxy model calls. It launches Pi with the credentials and plan you already use, so any usage is billed by your provider, not by Agentastic.
