FreeScout
An open-source PHP and Laravel help desk turning one or more email accounts into a multi-agent inbox with assignment, notes, collision detection, search, and optional modules.
Why use it
Use FreeScout to keep an existing support address while adding ownership, history, and shared visibility without paying a large SaaS fee for every agent.
Where it fits
Use analytics, feedback, player support, and updates to fix issues and decide what to improve after launch.
What to check
The core can be used commercially under AGPL-3.0, but many advanced capabilities are paid modules; self-hosting still requires web, database, mail-delivery, backup, and security maintenance.
