Luaup is a lossless Luau parser written in Luau. It is intended to be used within Roblox Studio plugins, as Roblox Studio offers no way to parse Luau or interact with a Luau AST.
There is currently no available documentation. If you have questions, feel free to ask me in the Roblox OSS Community discord server, linked here: https://discord.gg/mchCdAFPWU.
