## AI Code Preview

AI coding assistants hand you code as text, and checking whether that code actually works usually means copying it into a separate editor or a throwaway page. AI Code Preview removes that step. As soon as an AI response contains a code block, the extension detects it and gives you a live preview of what the snippet renders, directly alongside your conversation.

The extension supports the formats developers hit most often when working with AI tools: HTML, CSS, and JavaScript, plus React components and Vue single-file components. From the same panel you can copy the code or download it, and snippets run in an isolated sandbox so testing AI-generated output does not interfere with the rest of your browsing.

It is a free Chrome Web Store extension with a small, dedicated following and strong ratings. It is best understood as a focused verification tool — a way to confirm that AI-generated markup, styles, and components behave as intended before you commit them to a project.

**Pricing & Plans:** AI Code Preview is free. It is a free Chrome Web Store extension with no listed paid tier.

- **Real-time code preview:** See the rendered output of a code snippet immediately, without copying it into a separate editor or sandbox.
- **Multi-language support:** Preview HTML, CSS, and JavaScript together, as well as React components and Vue single-file components.
- **One-click copy and download:** Copy a snippet to your clipboard or download it as a file straight from the preview panel.
- **Smart code-block detection:** The extension recognizes fenced code blocks and their syntax automatically, so previews appear without manual setup.
- **Sandboxed execution:** Code is executed in an isolated sandbox, so you can test AI-generated snippets without risking your environment.

**Strengths:** Free Chrome Web Store extension with no paid tier; Live preview of HTML, CSS, JS, React, and Vue snippets; Sandboxed execution keeps testing isolated; Quick copy and download straight from the preview

**Limitations:** The listing was last updated in 2024, so very new frameworks may not yet be covered; Focused purely on previewing snippets — it is not a full IDE or project-level build tool

## 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
