## 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

## Piny

Piny is built for a workflow that is now common: an AI coding agent scaffolds pages and logic, then a human needs to fine-tune spacing, typography and copy without re-prompting for every pixel. Piny installs as a development dependency and a Vite plugin, opens a visual editor beside your app, and lets you click any element to select the JSX that renders it. From there you can adjust Tailwind spacing, color, type, flex and grid controls across breakpoints and states using your project's own theme, edit text, images and links, and inspect the class tree of an element and its parents.

Because Piny edits the source rather than generating overlays, the changes are ordinary code changes: your agent picks them up, and nothing is shipped into production builds. If your agent edits a file while you are editing it in Piny, Piny detects the change and avoids overwriting it. A "Target this element" feature copies an element's component, file and line so you can point your agent at exactly the right place in its next prompt.

Piny comes from the makers of Pinegrow Web Editor, though it is a separate product with its own licensing. There is a genuinely usable free tier with no account and no time limit — click-to-select, component tree, content editing, multiple page views, undo and redo. Pro adds the Tailwind and Grid controls, class inspector, structure and props editing, a Content Workspace for page text and data, and a component library you can register so your own components appear with previews and presets. Projects supported today are client-rendered React on Vite 5.2 or later; Astro support is in progress and Next.js is not supported yet.

**Pricing & Plans:** Freemium: a permanent free tier with no account required, plus Pro at $10/month or $60/year per developer (up to three computers). Pro includes a 14-day free trial started inside the editor, and yearly plans are refundable within 30 days. Orders are processed by Paddle.

- **Click-to-select JSX editing:** Click any element in the live preview and Piny finds the component and file that renders it, so edits land in the right place in your source.
- **Tailwind and Grid controls:** Adjust spacing, color, typography, flex and grid per breakpoint and state using your project's own theme, without hand-writing class strings.
- **Works next to your coding agent:** Runs inside Claude Code and Codex workflows; Piny picks up your agent's edits and avoids overwriting them, and Target this element hands your agent exact file and line references.
- **Content Workspace:** Edit page text, images and local data such as product lists and JSON through forms rather than hunting through source files.
- **Your own component library:** Register components so they appear with previews and presets, and edit their props with selects, sliders and image pickers.

**Strengths:** Edits are written directly to JSX and TSX, so nothing is added to production builds; The free tier is genuinely usable and needs no account or time limit; Designed to coexist with AI coding agents rather than replace them; Uses your project's actual Tailwind theme across breakpoints and states

**Limitations:** Currently limited to client-rendered React on Vite; Next.js is not supported and Astro is still in progress; Tailwind and class editing require the Pro subscription; Requires a Chromium-based browser and a locally running dev server
