PiDurableKit

Pi is an open-source AI agent harness and toolkit from earendil-works for building and running coding agents. Its packages provide a unified multi-provider LLM API, an agent runtime with tool calling and state management, an interactive coding-agent CLI, a terminal UI library with differential rendering, and vendor-neutral telemetry contracts and adapters. Slack and chat automation are provided through a separate package project. Pi does not provide built-in restrictions for filesystem, process, network, or credential access; it runs with the permissions of its launching user and process. The project documents containerization and sandboxing approaches, including a local Linux micro-VM, Docker, and policy-controlled sandboxing, for stronger isolation.

Pi Pocket is a self-hosted, mobile-first web application for running and supervising Pi coding agents on a user's own machine or phone. It stores model calls, tool calls, subagent activity, sessions, notes, schedules, and other state in a durable database so work can continue after server restarts; the web client receives committed session updates through server-sent events. The app supports live multiplayer sessions with presence, side chat, shared notes, mentions, reactions, pins, invitations, roles, and turn-taking. Users can steer or queue tasks, inspect tool output and diffs, fork or retry sessions, use git branches and worktrees, approve plan-mode changes, schedule messages, run goals until a check passes, and open a Chromium-based browser panel. It also provides artifacts, subagents, push notifications, extensions, codemode, and an optional Lancet Guard that requires approval for selected risky calls. Pi Pocket runs on Linux, macOS, Windows, or Android through Termux, requires Node.js 22.19 or newer, and can expose the app locally, over a LAN, through a Cloudflare quick tunnel, or through Tailscale. It is distributed under the MIT license. The project warns that anyone with steering access can make Pi run commands with the permissions of the host machine, and that Pi Durable is experimental.

PI-Desktop is a local-first desktop workspace for AI coding agents, built with Electron, a Rust host core, and the pi Agent Harness. It lets users open local projects, connect cloud or local models through providers such as OpenAI-compatible APIs, manage projects and long-running sessions, and review file changes and command output. Its architecture separates the React renderer, Electron desktop orchestration, Rust-managed permissions, filesystem access, SQLite persistence and secrets, and a pi Agent sidecar responsible for the agent loop, model interaction, and streaming. Agent, Plan, and Goal modes provide different approval boundaries; agents can read and edit files, run commands, and delegate exploration, implementation, research, testing, or review to background Subagents. The workspace supports MCP servers, Skills, installable Plugins, model and provider switching, session imports, notifications, context checkpoints, and a plugin marketplace. Conversations are stored locally as JSONL with a SQLite index, settings and logs remain on the machine, credentials use the operating-system keychain, and model requests go directly to the configured provider or endpoint. Plugin processes are permission-gated and isolated from the renderer, but plugins remain user-trusted code rather than a complete operating-system sandbox. It is an early-preview cross-platform application distributed for macOS, Windows, and Linux under the GNU Lesser General Public License v3.0.

Kit for AI is a service that provides a persistent memory and grounded-knowledge layer for AI agents. It exposes APIs and native memory tools that let agents call stored knowledge directly, supports ingesting files and URLs, and is intended to avoid building a separate retrieval-augmented generation stack. The site states the product works with any model and offers a free-to-start tier.
