## Description

NoPoW is a lightweight Chrome extension that removes annoying Proof-of-Work (PoW) captchas by switching the browser's User-Agent for affected requests. When it detects a PoW challenge signature, the site is added to a whitelist and a fake `user-agent` header is applied, allowing the page to bypass the PoW check and often work without JavaScript.

Currently supports Anubis (full bypass for non-JS flows) and partial support for go-away. Installation is simple: add the extension and it runs automatically — detecting PoW gates, activating on affected sites, and refreshing pages as needed. No user interaction is required. NoPoW aims to improve accessibility and browsing convenience while keeping things unobtrusive and easy to use.
