## Pi Coding Agent

Pi is a terminal-based coding agent built around one idea: the harness should adapt to your workflow, not the other way around. It keeps a deliberately small system prompt and core, which makes it token-efficient and lets you control exactly what lands in the context window. Instructions come from AGENTS.md files, a per-project SYSTEM.md, on-demand skills, reusable prompt templates and extensions that can inject context before each turn.

Instead of shipping every feature, Pi exposes primitives. Sub-agents, plan mode, permission gates, path protection, sandboxing, SSH execution, custom editors and status bars can all be built with extensions, asked for in natural language, or installed from third-party packages on npm and git. MCP is built in, and Codemode lets agents compose tool calls inside a JavaScript sandbox. Session history is stored as a tree, so you can rewind to any earlier message, branch from there, and export or share the whole thing.

Pi runs in four modes: the full interactive TUI, print/JSON mode for scripts and pipelines, an RPC protocol over stdin/stdout for non-Node integrations, and an SDK for embedding it in your own apps. It connects to 15+ providers including Anthropic, OpenAI, Google, Azure, Bedrock, Mistral, Groq, Cerebras, xAI, Hugging Face, OpenRouter and local Ollama, and you can switch models mid-session with a keystroke. Models, packages, changelog and docs all live on the project site.

**Pricing & Plans:** Free and open source (MIT). You only pay your chosen model or API provider; no subscription is required for the agent itself.

- **Extensible harness:** Build commands, tools, keyboard shortcuts, overlays, sub-agents or permission gates as TypeScript extensions, or install them as packages from npm and git.
- **Context engineering:** AGENTS.md instructions, per-project SYSTEM.md, on-demand skills, prompt templates and customizable compaction keep the context window under your control.
- **Multi-provider models:** Connect 15+ providers from Anthropic and OpenAI to Bedrock, Groq, OpenRouter and local Ollama, then switch models mid-session.
- **Four run modes:** Interactive TUI, print/JSON for scripting, an RPC protocol for non-Node hosts, and an SDK for embedding the agent.
- **Tree-structured history:** Rewind to any previous message, branch from it, and export to HTML or share the session via a gist URL.

**Strengths:** Open source under MIT with a minimal, readable core; Highly extensible: add or install the features other agents hard-code; Token-efficient thanks to a small system prompt; Broad model support with mid-session switching and local Ollama options

**Limitations:** Deliberately ships without sub-agents, plan mode or permission popups by default; You may need to build or install extensions to get a full-featured experience; Terminal-centric UI has a learning curve if you expect a GUI

## Playwriter

Playwriter is a developer tool that bridges AI agents with a real, everyday Chrome browser. Instead of spawning a separate headless Chrome instance, it installs a Chrome extension plus a CLI, then exposes the full Playwright API to an agent, script, or MCP client through one flexible execute tool. Because it runs inside the browser you already use, your logins, cookies, extensions, and saved state are all available to the agent immediately, which removes the repeated authentication dance that plagues fresh-browser automation.

The tool is built around a local WebSocket relay on localhost, so by default no page data leaves your machine. Agents gain capabilities that fixed tool-based browser servers typically cannot offer: streaming accessibility snapshots with automatic diffing, visual labels that map numbered refs to on-screen elements, isolated sessions that preserve state across tabs, JavaScript breakpoint debugging, a live code editor, network interception for API reverse engineering, and screen or RTMP recording. Optional features like remote control, cloud browsers with proxies and CAPTCHA solving, and browser sharing extend the same workflow to teammates, CI containers, and remote machines.

Playwriter positions itself against browser MCP servers that either launch a brand-new Chrome or expose a rigid set of commands. By handing the agent real Playwright code and reusing the user's browser, it aims for lower context usage, higher capability ceiling, and automation that feels like a human using their own machine. The project is distributed as an open-source extension and CLI and is widely used by developers automating web testing, scraping, and support workflows.

**Pricing & Plans:** Playwriter is distributed as a free Chrome extension and npm CLI, with cloud browser and relay options available; check the official docs for current plan details.

- **Full Playwright API via one tool:** Agents get a single execute tool that runs arbitrary Playwright code, avoiding schema bloat from dozens of predefined commands.
- **Real browser with your sessions:** Runs in your existing Chrome so logins, cookies, and extensions are already available — no separate headless instance or re-authentication.
- **Accessibility snapshots and visual labels:** Generate readable accessibility trees with automatic diffing, and overlay numbered visual labels that map refs to page elements.
- **Debugger, editor, and network capture:** Set JavaScript breakpoints, edit live code, intercept and replay network requests, and inspect response schemas without leaving the workflow.
- **Remote control and cloud browsers:** Optionally share your browser, tunnel to remote machines or containers, or use built-in cloud browsers with proxies and CAPTCHA solving.

**Strengths:** Reuses your real Chrome session, so authenticated flows work without repeated logins; Low context footprint because the agent calls one execute tool instead of many; Deep debugging, network inspection, and recording built on top of Playwright; Local relay keeps data on your machine by default, with optional remote and cloud modes

**Limitations:** Requires installing both a Chrome extension and a CLI, plus agent skill setup; Best results depend on the agent writing correct Playwright code; Advanced remote and cloud features add configuration and security trade-offs
