Hi HN, Over the last 2 years, we observed computer use models improving at a rapid pace and saturating benchmarks. This new benchmark replaces Online-Mind2Web with our own Browserbase Benchmark v2 that better represents the complex tasks that browser agents face in the real world. It runs against 23 models (frontier and open-weight) and 9 harnesses (Claude Code to LangChain Deep Agents) on accuracy, speed, and cost. This new benchmark confirmed our belief that the choice of an harness is becoming as important as the choice of a model. For example: claude-opus-5 runs 74% at $1.50/task on LangChain deep agents but 71% at ~$10/task on fx. The eval harness is a CLI you can run yourself (pick harness + tools/mcps + model, pass high-level tasks, grades with LLM verifiers, has trials/concurrency/OTEL tracing): https://github.com/browserbase/stag

We also just added Jev support https://github.com/browserbase/stagehand/pull/2952 On the act/extract/observe evals it shows promising results being extremely efficient - act: 4.3x faster, 97% fewer LLM calls. Pass rate: 97.5% -> 98.3%. - heldout: 4.1x faster, 78% fewer LLM calls. Pass rate: 87.5% -> 97.5%. - observe: 11.1x faster, 69% fewer LLM calls. Pass rate: 75.0% -> 83.3%. - extract: 8.7x faster, 75% fewer LLM calls. Pass rate unchanged at 92%. cost effectively 0
In We made Playwright 2x faster and 80% more token efficient

Show HN: Stagehand – an open source browser automation framework powered by AI

Hi HN! I’m Anirudh — longtime lurker, first time poster, and I couldn’t be more excited to show you Stagehand. Stagehand is a TypeScript project that extends Playwright with three simple AI methods — act, extract, and observe. We’d love for you to try it out using the command below: npx create-browser-app --example quickstart Here’s a sample workflow: const stagehand = new Stagehand(); await stagehand.init(); // Stagehand overrides the Playwright Page and Context classes const { page, context } = stagehand await page.goto("instadash.com") // Regular Playwright // Take action on the page await page.act({ action: "click on taqueria cazadores" }) // Extract relevant data from the page const { price } = await page.extract({ instruction: "extract the price of the super burrito", sche

ma: z.object({ price: z.number() }) }) We built Stagehand because we loved building browser automations using Playwright and Selenium, but we grew frustrated at how cumbersome it is to just get started and write simple browser automations. These frameworks, while incredibly powerful, are built for QA testing and are thus notoriously prone to fail if there are minor changes in the UI or underlying DOM structure. The goal of Stagehand is twofold: 1. Make browser automations easier to write 2. Make browser automations more resilient to DOM changes. We were super energized by what we’ve been seeing with vision-based computer use agents. We think with a browser, you can provide even richer data by leveraging the information in the DOM + a11y tree in addition to what’s rendered on the page. However, we didn’t want to go so far as to build an agent, since we wanted fine-grained control over each step that an agent can take. Therefore, the happy medium we built was to extend the existing powerful functionalities of Playwright with simple and extensible AI APIs that return the decision-making power back to the developer at each step. Check out our docs: https://docs.stagehand.dev We’d love for you to join and give us feedback on Slack as well: https://stagehand.dev/slack

Browserbase | Multiple Roles | San Francisco | ONSITE We're building infrastructure that enables developers and LLMs to programmatically interact with the web using our hosted headless browsers. A headless browser is just like the browser you're using right now, but running on a server. Running a single one isn't too bad, but running many of them becomes a complex exercise in stateful, distributed systems. We handle that, as well as provide great observability and other helpful features (like cookies management) to make developer's lives easier. While the infrastructure product is how we make money, we also maintain Stagehand (https://github.com/browserbase/stagehand), the AI-powered successor to Playwright. We built it to show how you can use LLMs to build dynamic web automations that don't depend on deterministic code. We're looking for
