    Cromite

    Cromite

    Cromite a Bromite fork with ad blocking and privacy enhancements

    Cromite is an open-source web browser project that originated as a fork of Bromite—a Chromium-based browser focused on ad blocking and enhanced privacy—and continues to evolve with built-in privacy protections and content filtering across Android, Windows, and Linux platforms. It retains the core goal of limiting tracking and intrusive ads by integrating ad blocking directly into the browser engine rather than relying on external extensions, all while striving to reduce telemetry, aggressive analytics, and close manufacturer integration. Cromite emphasizes user choice and control over web content, offering privacy-oriented settings and mitigations such as anti-fingerprinting measures and configurable filters to block unwanted elements. The project extends its focus beyond Android to desktop platforms, building packages that let users benefit from a more private browsing experience without sacrificing compatibility with modern web standards.

    DB Browser for SQLite

    DB Browser for SQLite

    The DB Browser for SQLite

    DB Browser for SQLite (DB4S) is a high quality, visual, open source tool to create, design, and edit database files compatible with SQLite. DB4S is for users and developers who want to create, search, and edit databases. DB4S uses a familiar spreadsheet-like interface, and complicated SQL commands do not have to be learned. This program is not a visual shell for the sqlite command line tool, and does not require familiarity with SQL commands. It is a tool to be used by both developers and end users, and must remain as simple to use as possible in order to achieve these goals. Import and export records as text, import and export tables from/to CSV files, import and export databases from/to SQL dump files, issue SQL queries and inspect the results, examine a log of all SQL commands issued by the application, plot simple graphs based on table or query data.

Please check with your organization before using GitHub Copilot. copilot-intructions.md is typically a single instruction file that contains default instructions for a workspace. These instructions are automatically included in every chat request.

    Selenium

    Selenium

    Browser automation framework and ecosystem

    Selenium automates browsers. That's it! What you do with that power is entirely up to you. Primarily it is for automating web applications for testing purposes, but is certainly not limited to just that. Boring web-based administration tasks can (and should) also be automated as well. If you want to create robust, browser-based regression automation suites and tests, scale and distribute scripts across many environments, then you want to use Selenium WebDriver, a collection of language specific bindings to drive a browser - the way it is meant to be driven. If you want to create quick bug reproduction scripts, create scripts to aid in automation-aided exploratory testing, then you want to use Selenium IDE; a Chrome and Firefox add-on that will do simple record-and-playback of interactions with the browser. If you want to scale by distributing and running tests on several machines and manage multiple environments from a central point.

    Chromium-Gost

    Chromium-Gost

    Chromium with support for GOST algorithms

    Chromium-Gost is an open-source web browser based on Chromium that adds support for Russian GOST cryptographic algorithms in secure connections. It extends Chromium's standard TLS functionality to work with websites requiring GOST-based encryption. The browser uses the Microsoft Security Support Provider Interface (msspi) to access compatible cryptographic providers installed on the operating system. It detects whether GOST algorithms are available and advertises their support during connection negotiation. When a website requires GOST encryption, Chromium-Gost can switch from the standard BoringSSL connection mechanism to msspi. This process is designed to operate transparently during browsing. Available for Windows, macOS, and Linux, it serves users and organizations accessing websites that depend on GOST cryptographic standards.

    BrowserOS

    BrowserOS

    Agentic browser; privacy-first alternative to ChatGPT Atlas

    BrowserOS is an open-source, agentic web browser built on a Chromium base that integrates AI agents directly into the browsing experience. Rather than just doing standard browsing, it places AI intelligence at the core: you can connect your own API keys (for e.g., OpenAI, Anthropic, Google Gemini) or run local models (via e.g., Ollama) so that your browsing data and automation stay on your machine — privacy and control are emphasized throughout. The interface remains familiar to users of Chrome (including support for Chrome extensions), but adds new capabilities: the browser can automate tasks for you, help you research by extracting and summarizing content, and enable agent-based workflows (e.g., “go fetch this info,” “fill this form,” “monitor this site”). The project is community-driven and entirely open source under the AGPL-3.0 license, which means you can inspect, fork, and contribute to the codebase.

    linuxdeployqt

    Makes Linux applications self-contained by copying in the libraries

    Makes Linux applications self-contained by copying in the libraries and plugins that the application uses, and optionally generates an AppImage. Can be used for Qt and other applications. This Linux Deployment Tool, linuxdeployqt, takes an application as input and makes it self-contained by copying in the resources that the application uses (like libraries, graphics, and plugins) into a bundle. The resulting bundle can be distributed as an AppDir or as an AppImage to users, or can be put into cross-distribution packages. It can be used as part of the build process to deploy applications written in C, C++, and other compiled languages with systems like CMake, qmake, and make. When used on Qt-based applications, it can bundle a specific minimal subset of Qt required to run the application. This tool is conceptually based on the Mac Deployment Tool, macdeployqt in the tools applications of the Qt Toolkit, but has been changed to a slightly different logic.
