OSF UI - Web Interface Framework and Mod Settings Menu (MCM)

An Open Source SFSE-powered framework for building mod UIs in HTML, CSS and JavaScript - shipping with the tools Starfield always lacked: a unified Mod Settings Menu (MCM) and a mod Keybinds manager.

OSF UI is an SFSE plugin that lets mods build their interfaces in HTML, CSS and JavaScript and draws them over the game - rendered by WebView2 , composited on Starfield's own Direct3D 12 device. Heavily inspired by Skyrim's Prisma UI framework.

Out of the box:

• []The Mods surface - press F10 (or the MOD MENUS entry in the pause menu): Opens an interface to manage every supporting mod in one place. No INI edits, no console commands, no alt-tabbing.[/]

  []Settings (MCM) - every supporting mod gets its own page of live controls: toggles, sliders, dropdowns, text and key fields, with live search, per-setting reset, and presets. Changes validate, clamp, and save instantly.[/]

  []Keybinds - a visual keyboard map of every registered mod's hotkeys. Click a key, press the new one, done - with conflict badges when two mods (or the game itself) want the same key.[/]

  The Mods surface is simply the first thing built on the framework - any mod can ship its own views, settings, and hotkeys through it. See it powering a full mod today: OSF Animation's scene browser, emote wheel, settings, and hotkeys all run on OSF UI.

  Status: early alpha. 1. 0. 0 is the first public build - working and verified in-game on Starfield 1. 16. 244, but expect rough edges. Bug reports are very welcome, here or on GitHub.

  []Rich Web Page UI In-Game - HTML/CSS/JS views rendered by WebView2, composited on the game's own D3D12 device.[/]

  []Fully interactive - While a view is open mods get full input control. And can optionally register hotkeys to callback into themselves[/]

  []Gamepad navigable - D-pad/stick moves focus, A activates, B closes, right stick scrolls. (Mod support dependent)[/]

  []Schema-driven settings - a mod drops one small JSON schema and gets a full settings page with persistence, migration, and hotkey delivery - no UI code at all[/]

  []Live hotkey service - every key setting is a real, rebindable hotkey delivered to its mod, gated so keys never fire into the console or a text field[/]

  []Localization built in - mod settings pages, custom views, and OSF UI's own interface all translate through simple drop-in JSON catalogs. The language follows the game's (or pick one in OSF UI's settings) and switches live, and partial translations fall back to English string by string.[/]
