Hi Product Hunt 👋 I'm the maker of T3rnel Browser — an AI browser automation extension that turns the Chrome, Edge, Firefox, Opera or Brave you are already signed into into a Model Context Protocol (MCP) server, and a developer toolkit you'll use every day without an agent. Why: every AI browser tool I tried launched a fresh headless browser with no cookies, so the agent could never get past a login. T3rnel gives the agent your real browser, with guard rails — passwords and tokens redacted before they reach the model, page text flagged for prompt injection, an approval gate you can switch on, a local audit log and a time-travel timeline. Everything in it: • Hover any element and copy its real CSS — as Tailwind, styled-components, Emotion, CSS Modules, SCSS, Less or a JSX style object • Pick any colour as hex, rgb(), hsl() or a CSS custom property; palettes from the whole page • Full-page screenshots that pin sticky headers once, load lazy content and dismiss cookie banners — annotate, crop, blur, export PNG/JPG/WebP/PDF • NEW: WhatsApp Web chats captured as one flowing conversation, the contact's name on top • Record a flow once and export a real Playwright, Puppeteer, Cypress or Selenium test • React inspector, network and console capture, accessibility/performance/SEO audits, link and spelling checks, visual diffs • Fill or clear forms safely, clear cache and hard-reload, stop infinite scroll on feeds • Markdown viewer with Mermaid and math, encrypted vault (AES-256-GCM) • 97 MCP tools; 24 languages; light and dark Your pages stay on your machine. The core tools are free, no account. Pro is one payment for three machines — PayPal, card, or EcoCash and OneMoney through PayNow — and switches itself on when the payment clears. Launch offer: share T3rnel with three friends or join the mailing list, then email t3ratech.dev@gmail.com for a launch-price code. I'd love your feedback — especially on the safety model. What breaks for you today when agents work on logged-in sites?
