Pi.dev Ecosystem 

The Pi coding agent is a terminal-first assistant focused on interactive workflows, extensibility, and running local agents with practical toolchains. The primary distribution today is pi-mono, which serves as the core runtime and extension point for the ecosystem.

For background on how Pi.dev and the agent evolved, see Mario Zechner’s write-up.

This page tracks the Pi-centric projects, adapters, and clients that extend the core agent, including alternate front-ends, web access tooling, and automation bridges within the wider collection.

FieldCategoryDateLinkNotes
Agent PlatformsTools2026Mercury

Personal AI assistant that runs in pi workspaces, bridges WhatsApp/Slack/Discord, and orchestrates containerized agents per space with APIs, chat routing, and extensions.

pi-generative-ui

Reverse-engineered generative UI extension for pi that streams interactive HTML/SVG widgets into native macOS windows via Glimpse, letting the LLM render live charts, sliders, diagrams, and dashboards.

Glimpse

lightweight macOS micro-UI toolkit for agent scripts using WKWebView + JSON-lines IPC, useful for pi companion windows, overlays, and generative UI experiments.

pi-gdocs

pi extension that lets agents read and update Google Docs design docs directly, preserving comments and formatting anchors better than Markdown copy-paste.

my-pi

Personal pi extension/skill bundle that adds todo, subagent, clipboard, notifications, file-watcher, code-ast, antigravity-image-gen, and memory, plus bundled browser/search + superpowers skills.

pi-tmux

tmux helpers for pi that coordinate long-running commands via pi-semaphore locks, offering tmux-bash/capture/send/kill/coding-agent, /tmux-list, and the /supervise <task> orchestrator while blocking unsafe git restore calls from the builtin helpers.

pi-side-agents

pi extension that spawns short-lived tmux/worktree side agents via /agent, tracks them in the statusline, offers /agents oversight, and provides agent-setup plus orchestration helpers for running asynchronous coding sprints.

pi-boy

Goofy pi extension that runs Game Boy/Game Boy Color ROMs via a bundled mGBA bridge, rendering inline or overlay with Kitty/ANSI fallbacks, ROM picker, and audio toggles.

pithagoras

hosted web UI for the pi coding agent with persisted sessions and host or container task execution

Pi for Excel

open-source multi-model AI sidebar add-in for Excel with 16 built-in spreadsheet tools, MCP gateway, and workbook recovery

Code AgentsTools2026pi_agent_rust

high-performance Rust port of pi-mono coding agent with instant startup, low memory footprint, and capability-gated security model

pi-queue

a lightweight task runner that accepts webhook tasks, requires human approval, and executes pi jobs in isolated git worktrees

Graphone

cross-platform desktop UI for the pi-mono coding agent, built with Tauri 2.0 and sidecar pattern

pi-agentic-compaction

pi extension that replaces one-shot prompt compaction with a virtual-filesystem summarizer that explores /conversation.json via jq/grep, supports configurable models and thinking levels, and accepts /compact <note> guidance.

pi-token-burden

pi extension that parses the assembled system prompt and shows a token-budget breakdown by section with a stacked bar and drill-down table

pi-companion

a web, mobile and desktop client for pi.

pi-mono

a coding agent and toolkit for building and managing LLM-driven agents and deployments.

pi-packages

collection of pi packages including extensions, skills, prompt templates, and themes such as multi-provider model, firecrawl, and image-generation integrations.

pi-autoresearch

pi extension + skill for autonomous experiment loops that benchmarks changes, auto-commits candidates, shows a live status widget and dashboard, and keeps or reverts edits based on measured results.

pi-btw

pi extension that adds a /btw command for immediate side questions, showing answers in an overlay without interrupting the current agent run and optionally saving the result.

pi-multi-pass

multi-subscription extension for pi with automatic OAuth account rotation, TUI /subs and /pool management, and cooldown-based failover across providers.

pz

a Zig-based, single-binary drop-in replacement for the pi coding agent

pi-tramp

TRAMP-like remote execution for the pi coding agent over SSH or Docker

rho

an always-on personal AI operator derived from pi that runs in the background, remembers context, and checks in on a schedule across macOS, Linux, and Android

pi-draw

a drawing/diagram extension for the pi coding agent by Armin Ronacher

pi-llamacpp

Experimental pi extension that runs and manages Qwen via llama.cpp for local agent workflows.

pi-boomerang

token-efficient autonomous task execution with context collapse for pi coding agent.

pi-interactive-shell

an interactive-shell extension for the pi coding agent with full PTY emulation and observable overlays

pi-mcp-adapter

Pi adapter that collapses MCP tool access into a lightweight proxy with lazy server startup, optional direct tools, and built-in MCP UI session support.

pi-web-access

web search, content extraction, and video understanding plugin for the pi-mono coding agent with smart provider fallbacks

PiApp

toy macOS/iOS app for experimenting with the PiSwift coding agent, with Claude chat, file browser, and terminal

pi-acp

ACP adapter that bridges pi’s RPC mode to ACP clients like Zed over JSON-RPC stdio

PiSwift

Swift port of pi-mono for embedding a coding agent in apps, with in-process subagents and prompt templates

InterfacesDesktop2026pi-gui

Electron desktop shell for pi sessions — lists workspaces and sessions, creates new conversations, and persists UI state; macOS arm64 beta with Homebrew cask planned
