    Ungoogled Chromium Android

    Ungoogled Chromium Android

    Android build for ungoogled-chromium

    Ungoogled Chromium Android is the Android platform build configuration and support tooling for Ungoogled Chromium on mobile devices, enabling privacy-minded users and developers to compile a version of the Chromium browser for Android that excludes Google-dependent services, telemetry, and tracking. This repository contains platform-specific patches, build targets, and integration scripts to adapt the upstream Chromium source for Android while eliminating components like Google Play Services hooks, automatic updater mechanisms, and preconfigured search engines that compromise privacy. The goal is to offer an Android browser that feels familiar in capability and rendering fidelity but does not phone home, engage with proprietary APIs, or leak usage data to third-party providers. Because Android’s ecosystem is heavily tied to Google’s app services, this effort focuses on ensuring core browsing functionality, tab management, extension support (as available), and performance optimizations.

    Helium Browser

    Helium Browser

    Private, fast, and honest web browser

    Helium is a Chromium-based web browser designed to deliver privacy, speed, and simplicity by removing Google’s proprietary services, telemetry, and bloat. It’s built atop ungoogled-chromium, extending its philosophy with additional privacy features, design refinements, and user experience improvements aimed at transparency and control. Helium blocks ads and trackers by default through an integrated, unbiased uBlock Origin extension prepackaged as a native browser component. Its UI and feature set emphasize minimalism, no “smart” recommendations, account sync, or background data collection, resulting in a distraction-free browsing experience that respects user autonomy. The browser is available across macOS, Linux, and Windows, each version built from a fully open source pipeline for reproducibility and trust. Development focuses on maintaining compatibility with modern web standards while decoupling Chromium from its Google dependencies and services.

    Ungoogled Chromium Windows

    Windows packaging for ungoogled-chromium

    Ungoogled Chromium Windows is the Windows build configuration and tooling for Ungoogled Chromium, a fork of the Chromium browser that removes Google-specific services, tracking, and invasive integrations to deliver a more privacy-respectful, user-controlled web experience on Microsoft platforms. This project specifically targets the Windows ecosystem, supplying build scripts, patches, and configuration files necessary to compile Chromium without telemetry, alternate error reporting, Google update mechanisms, built-in Google APIs, and other remote-service dependencies commonly embedded in stock builds. Users who need a modern browser engine with wide compatibility but without Google branding or background services can leverage this repository to produce Windows installers or portable builds that respect local privacy preferences.

    Ungoogled Chromium

    Ungoogled Chromium

    A lightweight approach to removing Google web service dependency

    In descending order of significance (i.e. most important objective first), ungoogled-chromium is Google Chromium, sans dependency on Google web services, ungoogled-chromium retains the default Chromium experience as closely as possible. Unlike other Chromium forks that have their own visions of a web browser, ungoogled-chromium is essentially a drop-in replacement for Chromium. ungoogled-chromium features tweaks to enhance privacy, control, and transparency. However, almost all of these features must be manually activated or enabled. In scenarios where the objectives conflict, the objective of higher significance should take precedence. Disable functionality specific to Google domains (e.g. Google Host Detector, Google URL Tracker, Google Cloud Messaging, Google Hotwording, etc.). This includes disabling Safe Browsing. Consult the FAQ for the rationale.

    SeleniumBase

    SeleniumBase

    A framework for browser automation and testing with Selenium

    SeleniumBase automatically handles common WebDriver actions such as launching web browsers before tests, saving screenshots during failures, and closing web browsers after tests. SeleniumBase lets you customize test runs from the command line. SeleniumBase uses simple syntax for commands. pytest includes automatic test discovery. If you don't specify a specific file or folder to run, pytest will automatically search through all subdirectories for tests to run. No More Flaky Tests! SeleniumBase methods automatically wait for page elements to finish loading before interacting with them (up to a timeout limit). This means you no longer need random time.sleep() statements in your scripts. SeleniumBase includes an automated/manual hybrid solution called MasterQA, which speeds up manual testing by having automation perform all the browser actions while the manual tester handles validation.

    node-gyp

    node-gyp

    Node.js native addon build tool

    node-gyp is a cross-platform command-line tool written in Node.js for compiling native addon modules for Node.js. It contains a vendored copy of the gyp-next project that was previously used by the Chromium team, extended to support the development of Node.js native addons. Note that node-gyp is not used to build Node.js itself. Multiple target versions of Node.js are supported (i.e. 0.8, ..., 4, 5, 6, etc.), regardless of what version of Node.js is actually installed on your system (node-gyp downloads the necessary development files or headers for the target version). node-gyp requires that you have installed a compatible version of Python, one of: v3.6, v3.7, v3.8, or v3.9. If you have multiple Python versions installed, you can identify which Python version node-gyp should use. A binding.gyp file describes the configuration to build your module, in a JSON-like format. This file gets placed in the root of your package, alongside package.json.

    hosts

    hosts

    Consolidate and extend hosts files from several well-curated sources

    Consolidating and extending hosts files from several well-curated sources. You can optionally pick extensions to block pornography, social media, and other categories. The unified hosts file is optionally extensible. Extensions are used to include domains by category. Currently, we offer the following categories: fakenews, social, gambling, and porn. Extensions are optional, and can be combined in various ways with the base hosts file. The combined products are stored in the alternates folder. Data for extensions are stored in the extensions folder. You manage extensions by curating this folder tree, where you will find the data for fakenews, social, gambling, and porn extension data that we maintain and provide for you. Create an optional blacklist file. The contents of this file (containing a listing of additional domains in hosts file format) are appended to the unified hosts file during the update process. A sample blacklist is included, and may be modified as you need.

    OpenWPM

    OpenWPM

    A web privacy measurement framework

    OpenWPM is a web privacy measurement framework that makes it easy to collect data for privacy studies on a scale of thousands to millions of websites.

Use device emulation to test your responsive web apps in mobile web browsers. Playwright supports headless (without browser UI) and headed (with browser UI) modes for all browsers and all platforms. Headed is great for debugging, and headless is faster and suited for CI/cloud executions. Playwright interactions auto-wait for elements to be ready. This improves reliability and simplifies test authoring. Playwright receives browser signals, like network requests, page navigations and page load events to eliminate the need for sleep timeouts that cause flakiness.
