AI Analysis
●●●BangerBig BrainWizardryZero to One
40x token reduction vs Playwright by returning tree deltas instead of DOM.
Strengths
- •State tokens and tree deltas cut HN frontpage from 2000 tokens to 50
- •Three native engines (WKWebView, WebKitGTK, WebView2) avoid Chromium bloat
- •Write operations verify tokens fail if page changed, preventing stale clicks
Weaknesses
- •Requires platform-specific WebView runtimes with different capabilities
- •Screenshot and layout features exist but text-first approach limits visual tasks

Post Description
I grew tired of numerous Chrome/Playwright/Puppeteer skills and MCP plugins, which for me felt quite heavy and unstable.
So I built this to allow my agents to efficiently test and work with websites.
