AgentFlow is an open-source AI agent starter kit engineered by Santosh Gautam. It couples Google Gemini's function calling with a Node.js ReAct execution loop and Server-Sent Events (SSE). When a user poses a goal, the AI autonomously decides which tools to invoke (e.g. calculator, weather, currency, system diagnostics), executes them in the backend sandbox, inspects the result, and streams the thought process and final response in real-time to a Vue 3 frontend.

PixGrow is a lightweight WordPress plugin that executes image compression inside the client's browser using WebAssembly (Wasm) codecs. It encodes media into WebP and AVIF formats without taxing the WordPress server CPU or requiring third-party SaaS API subscriptions.

The plugin listens to WooCommerce checkout events (Order Created, Processing, Completed) and triggers asynchronous REST requests to Meta's official WhatsApp Business Cloud API. It formats pre-approved template messages with localized order variables for instantaneous customer delivery.

The boilerplate provides a clean, object-oriented PHP foundation that handles WooCommerce gateway registration, secure checksum/SHA-512 callback verification, IPN webhook listeners, and sandbox-to-live configuration toggles.

Built using Python, Playwright, and Flask, the tool handles client-rendered SPAs, executes JavaScript, bypasses static crawler blocks, and recursively downloads all linked assets (HTML, CSS, JS, fonts, and images) while maintaining local directory hierarchy.
