Introduction

Small retailers often juggle dozens of Marketplace listings every week, manually uploading images, writing descriptions, and reposting at optimal times. The process is slow, error-prone, and difficult to scale. This automation platform provides a single dashboard to create listings, manage schedules, and let a browser automation engine take care of publishing them safely. It improves consistency, reduces workload, and helps businesses maintain steady visibility.

Smarter Listing Automation for Local Retail

• Reduces repetitive listing work by shifting publishing tasks to an automated desktop agent.
• Ensures consistent posting times to improve listing visibility.
• Supports multiple user accounts and sessions without interfering with one another.
• Handles media uploads, titles, categories, and pricing with minimal user effort.
• Designed to operate safely within platform constraints through rate control and session isolation.
