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. -

Open ChatGPT Atlas
Open Source and Free Alternative to ChatGPT Atlas
Open ChatGPT Atlas is an open-source toolkit and interface for working with OpenAI’s ChatGPT models in a more extensible, adaptable, and composable way than standard web UIs allow. It provides an architecture where developers and power users can manage state, tool integrations, and multi-turn workflows with more control, enabling custom UIs, automation layers, and advanced routing logic. Unlike a fixed chat app, Atlas is designed as a foundation that can be extended with plugins, external APIs, and custom logic to support domain-specific assistants, agent-like behaviors, and multi-task workflows. The project includes utilities for session management to preserve context across interactions, structured interfaces for streaming responses, and integration layers that let you plug in third-party tools and services. It often forms the basis for research, prototyping, or production systems where the default ChatGPT interface isn’t flexible enough. -

Tamper Dev
Extension that allows you to intercept and edit HTTP/HTTPS requests
If you are a developer, you can use Tamper Dev to debug your websites, or if you are a pentester, you can use it to search for security vulnerabilities by inspecting the HTTP traffic from your browser. Unlike most other extensions, Tamper Dev allows you to intercept, inspect and modify the requests before they are sent to the server. This extension provides functionality similar to Burp Proxy, MITM Proxy, OWASP ZAP, Tamper Data, and Postman Proxy, but without the need of additional software, with full support of HTTPS connections, and trivial to set-up (just install). -

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. -

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. -

JSONView
A web extension that helps you view JSON documents in the browser
A web extension that helps you view JSON documents in the browser. Normally when encountering a JSON document (content type application/json), Firefox simply prompts you to download the view. With the JSONView extension, JSON documents are shown in the browser similar to how XML documents are shown. The document is formatted, highlighted, and arrays and objects can be collapsed. Even if the JSON document contains errors, JSONView will still show the raw text. JSONView is a Web extension compatible with Firefox and Google Chrome that helps you view JSON documents in the browser. Once you've got JSONView installed, check out the example JSON file to see the extension in action! If you'd like to contribute to JSONView but don't want to code, consider contributing a translation. Copy the existing localization files from src/_locale and fill them in for your own language, then send a pull request. You can do it all from the GitHub interface. There's not many strings to translate! -

Choices.js
A vanilla JS customizable select box/text input plugin
Choices.js is a lightweight, configurable select box/text input plugin. Similar to Select2 and Selectize but without the jQuery dependency. Choices is compiled using Babel targeting browsers with more than 1% of global usage and expecting that features listed below are available or polyfilled in the browser. You may see exact list of target browsers by running npx browserslist within this repository folder. If you need to support a browser that does not have one of the features listed below, I suggest including a polyfill from the very good polyfill.io. Events fired by Choices behave the same as standard events. No jQuery dependency, configurable sorting, flexible styling, fast search/filtering, clean API, right-to-left support, custom templates. -

Easily import and export your cookie whitelist. Add the sites you want to keep cookies for to the whitelist (permanently) or greylist (until browser restart) Enable "Automatic Cleaning" in settings or "Auto-Clean" in popup. Watch those unused cookies disappear. Please keep in mind that at this time only Mozilla Firefox and Google Chrome (as well as its development branches e.g. Developer Edition, Canary) will be supported. Microsoft Edge Chromium will be considered partially official as it is using the same code as Google Chrome for now. -

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. -

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.
