FlareSolverr
Proxy server to bypass Cloudflare protection
FlareSolverr is a proxy server to bypass Cloudflare and DDoS-GUARD protection. FlareSolverr starts a proxy server, and it waits for user requests in an idle state using few resources. When some request arrives, it uses puppeteer with the stealth plugin to create a headless browser (Firefox). It opens the URL with user parameters and waits until the Cloudflare challenge is solved (or timeout). The HTML code and the cookies are sent back to the user, and those cookies can be used to bypass Cloudflare using other HTTP clients. Web browsers consume a lot of memory. If you are running FlareSolverr on a machine with few RAM, do not make many requests at once. With each request, a new browser is launched. It is also possible to use a permanent session. However, if you use sessions, you should make sure to close them as soon as you are done using them. It is recommended to install using a Docker container because the project depends on an external browser that is already included. -

Browserless
Deploy headless browsers in Docker
Browserless is an open-source browser automation platform for running headless browsers in Docker or through Browserless-hosted cloud infrastructure. It lets developers connect existing Puppeteer and Playwright code to remote browser sessions over WebSocket, which helps move heavy browser work away from local machines or application servers. The project also provides REST APIs for common automation tasks such as screenshots, PDF generation, scraping, crawling, and content export. Browserless is useful for teams that need scalable browser execution for testing, data collection, rendering, or AI-agent browsing workflows. Its deployment model supports self-hosting, private infrastructure, queues, concurrency controls, and enterprise-oriented configuration. The project’s main value is turning browser automation into a managed service layer that can be reused across applications and workflows. -

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. -

Gemma 4 Browser Assistant
On-device AI agent Chrome extension powered by Transformers.js
Gemma 4 Browser Assistant is an open-source browser extension that embeds an AI assistant directly into the browsing experience, powered by on-device machine learning models. It uses Transformers.js and Gemma models to run inference locally in the browser, eliminating the need for external servers and preserving user privacy. The extension includes a side panel interface that allows users to interact with the AI while browsing, enabling tasks such as summarizing pages and answering questions. It can access and analyze page content, browsing history, and tab state to provide contextual assistance. The architecture follows modern browser extension standards, with separate components for background processing, content scripts, and UI rendering. It also supports tool-calling capabilities, allowing the AI to perform actions such as navigating tabs or highlighting elements. Overall, it demonstrates how to build fully local, agent-based assistants inside web browsers. -

PostCSS
A tool for transforming CSS with JavaScript
PostCSS is a tool for transforming styles with JS plugins. These plugins can do a great number of things: transpile future CSS syntax, lint your CSS, support variables and mixins, and so much more. PostCSS works by taking a CSS file and providing an API to analyze and modify its rules (through its transformation into an Abstract Syntax Tree). The API can then be used by plugins to do a lot of useful things. With PostCSS, you can increase code readability by adding vendor prefixes to CSS rules; convert modern CSS so it's understood by more browsers; and avoid errors in your CSS via stylelint, a modern CSS linter. PostCSS currently has over 200 plugins, and is being used by industry leaders worldwide. -

YourInfo
Real-time browser fingerprinting demo with cross-browser tracking
YourInfo is a personal information management tool designed to let users securely store, structure, and retrieve their key data — such as contacts, credentials, personal notes, and preferences — while also enabling AI-assisted queries or reminders using that data. The platform prioritizes privacy by focusing on local storage or user-controlled databases, ensuring sensitive data stays under the user’s control rather than in third-party servers. Users can define types of information, tag entries for quick categorization, and perform intuitive searches when they need to recall something like a phone number, address, or secret detail. It also integrates with conversational models so that users can query “What’s my friend’s address?” or “Remind me of my travel dates” in plain language, and the system responds using secure data access while respecting permission boundaries. -

Browserosaurus
The browser prompter for macOS
Browserosaurus is an open-source (GPLv3 license), browser prompter for macOS. It works by setting itself as the default browser; any clicked links in non-browser apps are now sent to Browserosaurus where you are presented with a menu of all your installed browsers. You may now decide which app you’d like to continue opening the link with. Select from any of your installed browsers when clicking a link in a non-browser app. Download Browserosaurus from the GitHub releases page. Select x64 for Intel machines, or arm64 for Apple Silicon (M1) machines. Please note that Browserosaurus only officially supports the version of macOS that I currently use, which you can assume to be the latest stable version. -

A Node.js library to easily manage and rotate a pool of web browsers
Browser Pool is a small, but powerful and extensible library, that allows you to seamlessly control multiple headless browsers at the same time with only a little configuration, and a single function call. Currently it supports Puppeteer, Playwright and it can be easily extended with plugins. We created Browser Pool because we regularly needed to execute tasks concurrently in many headless browsers and their pages, but we did not want to worry about launching browsers, closing browsers, restarting them after crashes and so on. We also wanted to easily and reliably manage the whole browser/page lifecycle. You can use Browser Pool for scraping the internet at scale, testing your website in multiple browsers at the same time or launching web automation robots. -

Chromeless
Chrome automation made simple. Runs locally or headless on AWS Lambda
Chromeless is an open-source JavaScript library designed to simplify browser automation by controlling a Chrome or Chromium browser through an easy-to-use API. The project was created to make headless browser scripting more accessible for tasks such as automated testing, web scraping, and screenshot generation. Instead of manually interacting with browser debugging protocols, developers can use Chromeless commands to navigate pages, fill forms, click elements, and extract information programmatically. The library supports running Chrome locally during development or executing headless browser sessions remotely on cloud infrastructure such as AWS Lambda. This remote execution capability allows developers to run large numbers of browser automation tasks in parallel without managing their own browser servers. Chromeless was particularly notable for enabling serverless browser automation workflows that dramatically reduced testing times and simplified deployment pipelines. -

Sanity
Rapidly configure content workspaces powered by structured content
Sanity is an open-source real-time headless content management system that allows developers to manage structured content for websites, applications, and digital platforms. At the core of the system is Sanity Studio, a customizable editing environment built with React that can be configured to match the workflows and content models of different teams. Instead of using predefined content templates, Sanity allows developers to define schemas in code that determine how content is structured and stored. The platform stores data in a real-time backend called the Content Lake, enabling collaborative editing and instant updates across connected applications. Because the system separates content management from presentation, developers can use any front-end framework to display the data. Sanity also includes APIs and query tools that allow developers to retrieve content dynamically and integrate it into websites, mobile apps, and other digital services. -
