While we are happy to answer specific questions regarding the software’s functionality, please be aware that we cannot provide full, step-by-step installation support or server management training for free. This is a technical product intended for developers or users with experience in VPS management.

• Scope of Support: Support is provided exclusively for the WhatSaaS project. Issues related to VPS, Docker, or general infrastructure are outside our scope.

• Bug Reports: As an independent developer, I cannot offer immediate technical support. In the event of project bugs, please wait for the next scheduled update.

• This is not a plug-and-play product. Technical knowledge is required for its use and customization, as most modifications must be done directly through the code.
