What it is
SacredWare is a single desktop workspace for FastFlags. Keep keys and values in a table, group them into presets, import and export JSON, then Apply the set to a running Roblox session. Appearance, backups, and .swcfg files stay on your machine in AppData.
Features
Apply when Roblox is running
Edit FastFlags in the workspace, then Apply them to a live Roblox session. Auto Apply can repeat on an interval or at startup. Kill clears the applied configuration. Target a specific instance when more than one is running.
Built-in libraries and your own
One hundred seven included presets, grouped as Featured, Performance, FPS, Ping, Config, Fun, and User Configs. Save the current flag set as a named preset, or browse and merge into the editor.
Search, type, and status
A sortable table of name, type, value, and status. Search by name or value. Add, remove, import JSON, export, and backup. Double-click a row to edit bool, int, float, or string values.
SacredWareKnow what you are applying
Each flag can be classified against offset data: in offsets, not in offsets, unknown, string value, crash risk, or invalid format. Skip crash-risk flags on Apply. Remove flags in bulk by status.

Look, configs, and local files
Custom title, colors, table density, and an optional background photo with glass UI. Share look-and-general settings as .swcfg. Optional cursor and font overlays for detected Roblox installs. Everything lives in AppData.
Showcase
Flags table, preset browser, and classification — the same chrome the desktop app uses.
SacredWareHow it works
Import JSON, pick a preset, or edit flags in the table. Save a preset when the set is right.
Start Roblox, then Apply from SacredWare. Auto Apply can keep the configuration in sync on a timer.
Use Roblox with that configuration. Kill stops the applied set. Backup keeps a copy of your flags.

FAQ
A Windows desktop app for editing Roblox FastFlags and applying that configuration at runtime. The interface is a dark, frameless workspace with a flags table and a settings area for presets, appearance, configs, mods, and offsets.
FastFlags (FFlags) are named configuration keys Roblox uses internally. SacredWare lets you keep a local list of those keys and values, then apply the list to a running Roblox process.
Windows x64. The current installer is SacredWare-Setup-4.0.5.exe. The app is built as an Electron UI with a Windows sidecar. There is no macOS or Linux build in this project.
Your editor list is stored locally in %APPDATA%\SacredWare\ (flags.json, app_settings.json, presets.json). Apply is a runtime action against a running Roblox session; Kill stops that applied set. You can optionally have Kill also clear flags.json. Cursor and font mods, when you apply them, write into detected Roblox install folders. Backup copies your current flags from the toolbar.
Yes. Save the current flag set as a user preset, or load any of the 107 included presets (Featured, Performance, FPS, Ping, Config, Fun, User Configs). Look-and-general settings can be exported and loaded as .swcfg files.
Use Backup in the flags toolbar to snapshot flags.json. Import JSON from a file or paste. Load a saved preset or a .swcfg for appearance and general settings. Revert All to Default in Application settings restores the stock UI colors and table options.
The Windows installer for 4.0.5 is published at sacredware.vercel.app. The Download SacredWare button on this site points at that file.
The app can check the Vercel update feed on startup (optional) and offer the newer installer, or you can stay on the version you have. Settings → General also has a manual check.
