Short answer: VitaLite is an open-source Old School RuneScape client project on GitHub that you set up yourself. RLPlugins is a plugin platform: one launcher, a Discord sign-in and a catalogue of maintained plugins. They are related, not rivals: parts of the RLPlugins runtime build on VitaLite's open-source APIs.
What VitaLite is
VitaLite is an open-source OSRS client project built around RuneLite and published on GitHub. It gives developers working examples and APIs for things like dialogue, the Grand Exchange, the world map and client interaction. People searching for “VitaLite OSRS” usually want the client itself, or plugins that work with it.
What RLPlugins is
RLPlugins is a plugin platform for Old School RuneScape. You download one small updater, RLPlugins.jar, open it with Java 11 or newer on Windows or Linux, and sign in with Discord. The launcher opens the client with the plugins on your account and keeps them updated. The catalogue covers bossing, raids, PvP, skilling and Sailing, and its plugins are free for members of the RLPlugins Discord.
How they relate
The RLPlugins plugin runtime builds on VitaLite's open-source APIs, and some plugins name it directly: Gear Swapper lists VitaLite among its features. You do not build or install VitaLite yourself to use RLPlugins; the launcher handles the client.

Which one fits you?
Choose VitaLite if you write your own scripts and want the full source in front of you. Choose RLPlugins if you want ready plugins, such as Auto LMS or the Zulrah and Vorkath boss helpers, with updates and support handled for you.
The rules apply to both
VitaLite and RLPlugins are both independent of RuneLite and Jagex. Jagex's rules apply to what a plugin does, whichever client runs it, so read are RuneLite plugins allowed? before you rely on any third-party tool.
