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. -

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. -

Browser Pool
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. -

QA Wolf
Create browser tests 10x faster
Set up browser tests in minutes to find bugs before your users do. QA Wolf helps you create, run, and maintain end-to-end tests 10x faster. We found browser testing too difficult and often gave up on it entirely in our previous jobs. We built QA Wolf for developers like us who want to spend less time testing and more time shipping. QA Wolf is zero-effort automated QA. We get you to 80% coverage in four months, and keep you there, so your team can stay focused on shipping. 2/3 of tech companies have less than 50% test coverage. Why? Traditional QA strategies pit coverage against velocity. The more testing you do, the slower you ship. QA Wolf is different. By combining the best parts of in-house QA & test platforms, we deliver ultra-high end-to-end test coverage that never slows you down. First step is getting to know your app. You don’t have to have any kind of test plan; a short demo is all we need. -

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. -
