UMatrix
uMatrix is a browser network request filter that manages network traffic through a matrix-based interface. It functions as a granular traffic controller and web privacy firewall, allowing users to block or allow traffic based on the source, destination, and request type.
The project distinguishes itself through a point-and-click interface for managing first-party and third-party traffic. It provides a layered rule system for content security management and web privacy hardening, including the ability to spoof user-agent strings and control referrers on a per-site basis.
The system incorporates host-based blocklist management to import external lists and employs a hierarchical logic where narrow domain scopes override global defaults. Traffic controls are supported by top-level domain filtering and the ability to manually edit rules in a plain-text format.
Features
- Matrix-Based Filtering - Controls network traffic using a point-and-click matrix that maps source and destination domains to allowed request types.
- Browser Resource Controllers - Manages which scripts and resources can load on a webpage using a granular point-and-click interface.
- Top-Level Domain Mapping - Maps network requests to the corresponding matrix row by identifying the top-level domain.
- Manual Network Request Filtering - Provides manual filtering of network requests based on source and destination across different domains.
- First-Party Request Rules - Provides dedicated rule controls for managing network traffic directed specifically at the current web page domain.
- Network Privacy Hardening - Hardens web privacy by controlling referrers and user-agent strings to prevent tracking and data leaks.
- Browser Privacy Firewalls - Provides a comprehensive system for user-agent spoofing, referrer controls, and domain-wide blocking to enhance privacy.
- Content Security - Applies a layered system of rules to restrict the loading of web resources from specific origins on a per-site basis.
- First- and Third-Party Request Controllers - Manages first-party and third-party traffic through a layered rule system and point-and-click interface.
- Network Request Filters - Intercepts and blocks network traffic based on source, destination, and resource type via a matrix interface.
- Hosts and DNS Blocklist Managers - Imports and applies external host-compliant blocklists to prevent connections to specific domains.
- Hierarchical Rule Evaluators - Evaluates filtering rules in a hierarchical structure where specific domain settings override global defaults.
- HTTP Header Spoofing - Intercepts outgoing request headers to spoof referrers and user-agents based on predefined site rules.
- Layered Scope Resolution - Implements a layered system where narrow domain settings override broader global filtering rules.
- External Filter List Integrations - Imports and parses external third-party blocklists to automatically mark domains as blocked.
- Domain Blocklists - Support for loading host-compliant blocklists from external URLs to block specific hostnames system-wide.
- Domain Privacy Overrides - Sets specific user-agent and referrer spoofing rules for individual hostnames to override global defaults.
- Domain Filtering Rules - Provides the ability to create and manage filtering rules that apply to entire top-level domains.
