FreeScout

FreeScout is a super lightweight and powerful free open source help desk and shared inbox built with PHP (Laravel framework). It serves as a self-hosted alternative to Zendesk and Help Scout, allowing you to maintain complete control over your customer support data without giving up privacy or being locked into a service you don't control. Key features include unlimited support agents, tickets, and mailboxes with no limitations. The platform offers seamless email integration, multilingual support (25+ languages), mobile-friendly interface, and collision detection to prevent agent conflicts. FreeScout supports modern Microsoft Exchange authentication, push notifications, auto-replies, internal notes, and automatic conversation refreshing. The solution is designed with a strong focus on security and can be easily deployed even on shared hosting with minimal system requirements. It includes features like starred conversations, forwarding, merging conversations, phone conversation support, open tracking, search functionality, and the ability to paste screenshots directly into replies. FreeScout offers optional paid modules for extended functionality including WhatsApp integration, Facebook integration, Telegram integration, Knowledge Base, CRM features, time tracking, custom fields, workflows & SLA, real-time reports, and many other professional features. The core application remains completely free and open source under AGPL license.
