## Oxygen

Oxygen occupies an unusual position: it is both a hand-crafting visual builder and an execution layer for AI agents. The classic side gives designers and developers a canvas with one-to-one CSS properties, a class-first workflow, global variables, reusable components, interactions, dynamic data, query loops, custom post types and custom fields — a workflow that feels closer to writing clean front-end code than to stacking widgets. Output is intentionally lean, which matters for performance-focused sites and client builds.

The 6.2 release added the other half: a built-in MCP server. After installing the plugin on a local, staging or live WordPress site and running the setup wizard, you connect an agent such as Claude, Codex, Cursor or OpenCode. From there you describe what you want in plain language and the agent creates native Oxygen elements — a property listings post type with custom fields and filtered archives, a WooCommerce shop with variations and taxonomies, Yoast SEO fields for every page, a Figma design rebuilt with real classes and global variables. Everything it produces is editable in the visual editor afterwards, so you can switch between prompting and hand-tuning at any point.

Oxygen is licensed by Soflyy, has been in production for around a decade and is used by a large builder community. It targets agencies, freelancers and developers who want WordPress sites with clean markup and no page-builder bloat, and who are now experimenting with agent-driven development. A single one-time license covers unlimited sites, with no per-seat or renewal fees, and a free trial lets you evaluate the full editor and AI tooling first.

**Pricing & Plans:** One-time purchase: $199.50 for a license covering unlimited sites, with a 60-day money-back guarantee, no renewals and no per-seat fees. A free trial provides the full editor and AI tooling so you can evaluate before buying.

- **Agent Connector with built-in MCP server:** Ships with an MCP server and Abilities API support, so Claude, Codex, Cursor or any MCP-compatible agent can build directly inside your WordPress site without extra plugins or AI credits.
- **One-to-one CSS visual editor:** Full control over layout, styling, animations, interactions and variables through a class-first, CSS-accurate canvas that produces clean, highly optimized markup.
- **Dynamic WordPress content:** Build with custom post types, custom fields, query loops, reusable components and Advanced Custom Fields for content-driven sites rather than static pages.
- **WooCommerce and plugin automation:** Agents can install and configure plugins, set up shop, product and cart templates with variations and taxonomies, and manage orders, users and roles.
- **Global variables, components and templates:** Define design tokens once and reuse them across pages via global variables, reusable components and shareable templates for faster client builds.

**Strengths:** One-time license covering unlimited sites with no renewal or per-seat fees; AI agent workflow and full manual visual editor in the same product; True one-to-one CSS control and clean HTML output instead of wrapper markup; Free trial of the full editor and AI tooling before you commit

**Limitations:** Agent-driven building depends on an external MCP-compatible client you supply; Requires comfort with WordPress concepts such as custom post types, ACF fields and CSS classes; A one-time price is a larger upfront commitment than a low monthly subscription

## 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
