Weaver
A fast, lightweight game framework for Roblox
Simple Structure
Since Weaver is built around a single-script architecture, communicating between multiple modules is seamless - ditto for communication between the server and the client.
Painless Networking
Due to the nature of Weaver, all networking is made simple, as services and controllers natively support Weaver's RemoteSignal implementation; you don't need to use any Instances.
Effortless Integration
Weaver doesn't take much effort to install. Once it's added into your Roblox project, there is little setup required to get it working as intended and integrated with your codebase.
