🚀 I Built a WhatsApp Web Automation Chrome Extension (Manifest V3)

Hey devs 👋
I want to share a project I recently launched: WhatsApp Automator, a Chrome extension that helps automate WhatsApp Web messaging in a safe, human-like, and privacy-focused way.

🤔 Why I Built This

Most WhatsApp automation tools I found were either:

Too aggressive (high risk of bans), or

Closed-source and ignored user privacy

I wanted to build something:

Developer-friendly

Transparent

Focused on safety and privacy

Fully compatible with Chrome Manifest V3

⚙️ What the Extension Can Do
🔄 Smart Automation

Send multiple messages automatically

Random delays between messages to mimic human behavior

Min/Max delay enforcement to avoid spam-like actions

⏰ Scheduling

Schedule message campaigns for a specific date and time

Supports delayed start with Chrome alarms

📥 Multiple Input Modes

JSON mode – paste a raw array of messages

Form Builder – add/remove messages via UI

Profiles mode – load users with phone & messages

API import (POST) – fetch campaigns from a backend

Auto-polling – periodically check for new configs

🎛️ Full Control

Start, Pause, Resume, Stop at any time

Settings persist even after closing Chrome

🔒 Privacy-First Features

I also added privacy tools for people who work in public or shared environments:

Blur chat messages

Blur recent chat previews

Blur images & videos

Blur profile photos

Blur message input area

Hover to reveal temporarily

🧠 Tech Stack & Architecture
