Penumbra is a runtime mod loader for FINAL FANTASY XIV, with a bunch of other useful features baked in:

• No need to back up your install - mods don't touch game files
• Disable and enable mods without restarting the game
• Resolve conflicts between mods by changing mod order
• Files can be edited and are often replicated in-game after a map change or closing and reopening a window

Penumbra, in its current state, is not intended for widespread use. It is mainly aimed at developers and people who don't need their hands held (for now).

We're working towards a 1.0 release, and you can follow it's progress here.

Contributions are welcome, but please make an issue first before writing any code. It's possible what you want to implement is out of scope for this project, or could be reworked so that it would provide greater benefit.

Penumbra has support for most TexTools modpacks however this is provided on a best-effort basis and support is not guaranteed. Built in tooling will be added to Penumbra over time to avoid many common TexTools use cases.
