    Dillo

    Dillo

    Dillo, a multi-platform graphical web browser

    Dillo is a lightweight, minimal graphical web browser, designed for speed, low resource usage, and privacy. It is written in C and C++ using the FLTK (Fast Light Toolkit) GUI library. Its goals include enabling web access on old or constrained hardware, using slow or unreliable network connections, minimizing dependencies, and avoiding many of the complexities and overheads of modern full-featured browsers. It omits many modern features (notably JavaScript), instead focusing on rendering HTML (mostly older/standardized subsets), images, and some CSS, while keeping the codebase small. It is free/open source under GPL-3.0.

    Stylus for Chrome

    Stylus for Chrome

    Stylus - Userstyles Manager

    Stylus is a fork of Stylish for Chrome, also compatible with Firefox as a WebExtension. "Stylus" is a fork of the popular Stylish extension which can be used to restyle the web. Not "ish", but "us", as in "us" the actual users. Stylus is a fork of Stylish that is based on the source code of version 1.5.2, which was the most up-to-date version before the original developer stopped working on the project. The objective in creating Stylus was to remove any and all analytics, and return to a more user-friendly UI. We recognize that the ability to transfer your database from Stylish is important, so this is the one and only feature we've implemented from the new version. Two different optional code validators with user-configurable rules: CSSLint and Stylelint. Both validators use Web Worker API to run in a separate background thread inside the editor tab without blocking your interaction with the code.

    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.

    Dev Browser

    Dev Browser

    A Claude Skill to give your agent the ability to use a web browser

    Dev Browser is a browser automation skill/plugin that enables an AI agent to control a real browser for verification and testing during development. Its purpose is to close the gap between “code was written” and “the UI actually works,” by letting the agent navigate, interact with pages, and validate behavior in a live environment. A key idea is persistence: the browser can keep pages open so the agent can navigate once and then perform multiple interactions across scripts without losing state each time. It supports flexible execution modes, allowing full-script runs when tasks are straightforward and step-by-step exploration when the agent needs to inspect or iterate carefully. To make automation more reliable for language models, it provides LLM-friendly DOM snapshots that structure the page in a way that is easier for an agent to interpret than raw HTML dumps.

    Lightpanda Browser

    Lightpanda Browser

    Lightpanda: the headless browser designed for AI and automation

    Lightpanda is an open-source headless browser designed specifically for automation, artificial intelligence workflows, and large-scale web interaction tasks. Unlike traditional browsers that include full graphical rendering engines meant for human users, Lightpanda is built from scratch to operate entirely in headless mode, focusing only on the components required for programmatic web interaction. This design allows it to execute JavaScript and interact with web pages while avoiding the overhead associated with rendering images, fonts, and layout elements intended for visual display. The browser is implemented using the Zig programming language and integrates the V8 JavaScript engine to run modern web applications and scripts efficiently. Because it avoids graphical rendering and other heavy browser components, the system uses significantly less memory and launches almost instantly compared to conventional browsers such as Chrome.

Opera shares Chrome's underlying engine, so you can install uBlock simply by grabbing the latest release for Chrome.To benefit from uBlock's higher efficiency, it's advised that you don't use other blockers at the same time (such as AdBlock or Adblock Plus). uBlock will do as well or better than most popular ad blockers. It's important to note that blocking ads is not theft. Don't fall for this creepy idea. The ultimate logical consequence of blocking = theft is the criminalisation of the inalienable right to privacy.

    camofox-browser

    Headless browser automation server for AI agents to visit sites

    camofox-browser is a headless browser automation server built specifically for AI agents that need to interact with websites that often block standard automation stacks. It wraps Camoufox, a Firefox fork that performs fingerprint spoofing at the C++ level, which means many browser characteristics are altered before page scripts can inspect them, rather than relying on JavaScript-layer stealth patches. The project is designed around a REST API, making it easier for agents and external tools to create tabs, navigate pages, click elements, type input, scroll, capture screenshots, and manage browsing sessions programmatically. Instead of returning large volumes of raw HTML, it emphasizes accessibility snapshots and stable element references, which reduces token usage and creates more reliable interaction flows for AI-driven browsing. It also supports practical operational features such as per-user session isolation, cookie importing for authenticated browsing, proxy and GeoIP routing.

    user.js

    Firefox privacy, security and anti-tracking: a comprehensive user.js

    A user.js is a configuration file that can control Firefox settings - for a more technical breakdown and explanation, you can read more in the wiki. The arkenfox user.js is a template that aims to provide as much privacy and enhanced security as possible and to reduce tracking and fingerprinting as much as possible - while minimizing any loss of functionality and breakage (but it will happen). Everyone, experts included, should at least read the wiki, as it contains important information regarding a few user.js settings. Note that we do not recommend connecting over Tor on Firefox. Use the Tor Browser if your threat model calls for it, or for accessing hidden services. Also be aware that the arkenfox user.js is made specifically for desktop Firefox. Using it as-is in other Gecko-based browsers can be counterproductive, especially in the Tor Browser.

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.
