GUST v4.0

Brave

WISP Server

WebSocket URL

Current server shown above

WISP Pool (Round-Robin)

Enable pool round-robin

Rotate across a benchmarked pool of public WISP servers for faster loads. Servers that fail for a site are skipped for that site; faster servers are picked more often.

Not benchmarked yet

Concurrent Requests

Idle threads

Max simultaneous requests when page is loaded (default: 3). Lower = less background CPU.

Active threads

Max simultaneous requests during page load (default: 6). Higher = faster loads but more CPU.

WebRTC Blocking

Block WebRTC connections

Prevents sites from establishing direct peer-to-peer connections that bypass the WISP tunnel and could expose your real IP address. Off by default — may break video calls and real-time apps.

Smart Request Headers

Spoof Sec-Fetch & Referer headers

Synthesize correct Sec-Fetch-Site, Sec-Fetch-Mode, Sec-Fetch-Dest, and Referer headers based on request context. Fixes CDNs and APIs that reject requests with incorrect fetch metadata.

Provider

Context

Page context by default

Automatically enable Page Context when the assistant opens.

Default Search Engine

Custom Search Engine

Engine Name

Display name for the custom engine in the picker.

Search URL

Use {q} as the query placeholder. Only used when Custom engine is selected.

Spellcheck [broken]

Enable spellcheck

Check spelling in text fields and textareas (e.g. search bar, forms).

Tab Favicons

Proxy favicons through WISP

Fetch tab favicons through the WISP server instead of Google's favicon service. More private, but slightly slower.

Privacy & Blocking

Ad & Tracker Blocking

Blocks analytics, ads, and tracking scripts

Paused Sites (Allowlist)

Adblock is paused on these sites. One hostname per line. Use "Pause for this site" in the shield popup to add sites.

User-Agent Spoofing

Request User-Agent

Sent as the User-Agent HTTP header for all proxied requests.

Page navigator.userAgent

Overrides navigator.userAgent inside loaded pages.

Blocklist & Filters

Custom Filter Rules

Enter CSS selectors to hide (one per line). Example: .ad-banner

Tab Cloak

Enable Tab Cloak

Disguise the GUST tab with a custom title and icon.

Tab Title

Custom text shown as the browser tab name.

Favicon

Paste an image link or upload your own icon.

Presets

History Cloak

When enabled, opening GUST pauses at a privacy screen. Press any key to relaunch it inside about:blank while the original tab redirects to Google. Takes effect the next time GUST opens.

Tab Caching

Keep tabs loaded in background

When enabled, switching between tabs won't reload them. Disable to save memory.

Resource Cache

Cached Resources

Calculating...

Font Size

Adjust text size across the entire interface

Default

Panel Widths

Remember panel widths

When enabled, panel widths are saved. When disabled, they reset to default on close.

Panel Position

Panels on the left

Move side panels to the left side of the browser window instead of the right.

Fullscreen on Launch

Start in fullscreen

Automatically enter fullscreen on your first click or keypress after opening Gust.

Browser Skin

Disguise GUST as another browser. Tabs, toolbar, menus and browser-specific extras are all re-dressed to match the real thing.

*A note on GUST+. By default, GUST+ is identical to regular GUST. However, GUST+ allows you to hand pick tab styles, sidebars, home screens, and more from whichever skin does it best, then paint the whole thing in custom colors. Tune it below.

Identity

Match User-Agent to skin

Websites will see the masked browser's User-Agent string, not just its looks. Managed automatically while a skin is active — reload open pages to apply.

Opera GX Extras

UI sound effects

GX-style clicks and blips on tabs, buttons and the sidebar. Only active while the Opera GX skin is on.

GUST+ Studio

Build your own browser. Every row borrows that piece from a real mask — mix Chrome's tabs with Brave's toolbar and a Zen sidebar, or anything else. Touching any control switches you to the GUST+ mask.

Color theme

Tab strip

Toolbar

Address bar

Browser menu

Home screen

Sidebar

Zen vertical tabs replace the tab strip and toolbar entirely — the Tabs and Toolbar picks above go dormant while it's on.

Preset

GUST+ Toolbar & Modules

Every button and extra is its own switch — strip the toolbar to nothing or turn everything on at once. Applies while the GUST+ mask is active.

GUST+ Color Lab

Repaint anything. Core palette drives the whole UI; below it, every color the borrowed parts actually use is listed — click a swatch to change that exact pixel color everywhere it appears.

Core palette

Borrowed-part colors

Pick some borrowed parts first — their colors will appear here.

Fallback Behaviour

Enable fallback on load error

When a page fails to load (network error, bad status, timeout), automatically retry using the fallback proxy before showing an error page.

Log retries

All fallback retry attempts are always written to the request log, including which WISP server was used.

always on

Fallback WISP Server

Fallback WebSocket URL

Used only when the primary WISP server is unreachable or returns an error. Leave blank to disable.

Retry Policy

Max retry attempts (main)

How many times Gust retries on the primary WISP server before switching to the fallback.

Max retry attempts (fallback)

How many times Gust will attempt the fallback WISP before giving up and showing an error.

Retry delay (seconds)

Wait time between each retry attempt before switching to the fallback server.

Error Triggers

Fallback on HTTP 5xx errors

Retry via fallback when the origin server returns a 500-level status code.

Fallback on timeout

Retry via fallback when the primary server exceeds the connection timeout.

Fallback on DNS failure

Retry via fallback when the hostname cannot be resolved.

Advanced Rendering

Script tags loaded per page

Maximum number of <script src> tags loaded when rendering a page. Higher values help complex React / Next.js / Vite apps but use more memory. Default: 250.

250

Images prefetched per page

Maximum number of images fetched and inlined before the page is displayed. Lower values speed up initial load on image-heavy sites; higher values improve visual completeness. Default: 300.

300

Media Range Requests

Enable Range request support

Forward Range headers and handle 206 Partial Content responses. Fixes video/audio seeking and embedded media playback on most sites.

Unknown File Types

Auto-download unknown files

When Gust receives a file it can't display (e.g. .zip, .exe), automatically trigger a browser download instead of showing an error page.

PDF Viewer

Built-in PDF viewer

Render PDF files inline using a built-in viewer powered by PDF.js instead of downloading them.

Image Viewer

Built-in image viewer

Display images (PNG, JPEG, GIF, WebP, SVG…) in a clean fullscreen viewer with zoom and pan.

Video Player

Built-in video player

Play video files (MP4, WebM, OGG…) in a built-in player with controls.

Audio Player

Built-in audio player

Play audio files (MP3, OGG, FLAC, WAV…) in a styled player instead of downloading.

Text / Code Viewer

Built-in text viewer

Display plain text, JSON, XML, CSV, and source code files inline with syntax-aware formatting.
