A downloadable launcher for Windows

Note: due to frequent updates and large file size, I highly recommend you to use the itch.io app to download the mod or download the "Lite" version.

If you need Novetus versions 1.0 or lower, go to the Novetus Archive.

Novetus is a free and open source multi-version ROBLOX client launcher built to allow the user to run LAN and Internet servers.

Novetus was made as a successor to my old RBXLegacy project, with the addition of new features that enhance the launcher for mod development, player customization, and overall usability.

Novetus is based on RBXLegacy 1.16.2, however it uses some features from RBXLegacy 1.18, such as extended customization, better layout, improved networking features, avatar previewing, and more.

Enhancements from RBXLegacy The Final Update 1.16.2 & 1.18.1:

- Fully offline customization and wider customization options

- Enhanced 3D Avatar Preview

- An expanded SDK with many tools to use.

- Improved UPnP functionality

- Ability to reset server/client port to default

- Easier to read join tab note

- Better launcher and client security

- Sharing of customized players with other players.

- ClientScript scripting language for creating more customized client command arguments

- Better client support. (from March 2007 up to the latest ROBLOX client with ClientScript!)

- Custom client warnings

- Command arguments for different functions

- Many more items

- Redesigned launcher

- Largely reworked codebase

- Custom player icons

- And more!
