README

A lightweight, embeddable lead capture system for PHP. Beautiful forms, SQLite storage, email notifications, optional reCAPTCHA v3 — all in a single Composer package with zero build steps for consumers.

Features

• Embeddable lead forms — iframe or JS snippet, works on any website
• Configurable fields — text, email, phone, URL, textarea, multi-select checkboxes
• Pre-compiled Tailwind CSS — beautiful out of the box (~15KB), customizable colors
• SQLite storage — zero database setup, WAL mode enabled
• Email notifications — SMTP, Sendmail, or SES (sent after response for fast submissions)
• API ping — POST lead data to your own API/webhook on each submission (deferred)
• reCAPTCHA v3 — optional, configurable score threshold
• Admin panel — view leads, filter by date, export CSV
• Lightweight — <20KB iframe payload, no frontend framework
