OpenTabs calls APIs.** Playwright, Puppeteer, and Stagehand simulate a human — click, type, read the screen. OpenTabs skips all that. It calls the same internal APIs the web app's own frontend calls, through your browser, using your existing session. Exposed as [MCP tools](https://modelcontextprotocol.io/). No screenshots. No DOM scraping. No pixel-guessing. <figure> <img src="assets/demo-hero.gif" alt="Demo: AI checks stocks, orders Panda Express, and sends a Discord message — all through the browser" /> <figcaption><p align="center">_{AI checking Robinhood, ordering Panda Express, and messaging on Discord — all through open browser tabs}</p></figcaption> </figure> --- ## Quick Start You need [Node.js](https://nodejs.org/) 22+ and Chrome. ```bash npm install -g @opentabs-dev/cli opentabs start ``` First run prints MCP config blocks you can paste into [Claude Code](https://github.com/anthropics/claude-code), Cursor, or Windsurf. Load the extension from `~/.opentabs/extension` via `chrome://extensions/` (Developer mode → Load unpacked). ```bash opentabs plugin install <plugin-name> ``` Five minutes, start to finish. See the [Quick Start guide](https://opentabs.dev/docs/quick-start). ## 100+ Plugins, ~2,000 Tools `discord_send_message` hits Discord's real backend — fast, deterministic, cheap on tokens. Slack, Discord, GitHub, Jira, Notion, Figma, AWS, Stripe, Robinhood, Panda Express, Airbnb, and [a lot more](plugins/). Plus built-in browser tools (screenshots, clicking, typing, network capture) that work on any tab without a plugin. ## Build a Plugin Point your AI at any website. It analyzes the page, discovers the APIs, scaffolds the code, and registers it. ```bash opentabs plugin create my-app --domain .example.com cd my-app && npm install && npm run build ``` Publish to npm and anyone can `opentabs plugin install` it. See the [Plugin Development guide](https://opentabs.dev/docs/guides/plugin-development). ## Security - **Everything starts off.** Every plugin is disabled by default — not "ask," actually off. - **AI-assisted code review.** Your AI reviews the adapter source before you enable it. - **Version-aware.** When a plugin updates, permissions reset. New code, new review. - **Three permission levels.** Off, Ask (confirmation dialog), or Auto. Per-plugin or per-tool. - **Runs locally.** No cloud. Everything in `~/.opentabs/`. Full audit log. Anonymous [telemetry](https://opentabs.dev/docs/reference/telemetry) (opt-out). ## How This Was Built Built entirely by AI agents — zero hand-written application code. Hundreds of PRDs executed by [Claude Code](https://github.com/anthropics/claude-code) workers via [Ralph](https://github.com/snarktank/ralph).
