Browserbase Skills

Browserbase just turned Claude Code into a real web agent. The browserbase/skills repo went live in October 2025 and exploded onto GitHub Trending the week of May 4-5, 2026 with a wave of new agent skills designed specifically for the Claude Code Agent SDK. 3,188 stars and 212 forks as of today. This is the production-grade browser-automation SDK that's been missing from the Claude Code ecosystem. You install the marketplace, pick the skills you need, and Claude gains real browser capabilities — not a sandbox, not a screenshot trick, but a full Browserbase remote session that can log into your accounts, scrape JavaScript-rendered pages, run adversarial UI tests, and deploy serverless browser functions. The 11 skills shipped today browser — CLI-driven web automation against remote Browserbase sessions. browserbase-cli — the official bb CLI for managing platform workflows from Claude. functions — deploy serverless browser automation to Browserbase's cloud, callable from any agent. site-debugger — diagnose and auto-fix failing automations. The skill that pays for itself in saved hours. browser-trace — capture full DevTools protocol traces. Critical for debugging flaky tests. safe-browser — local agent SDK with domain allowlist enforcement, so the agent can't wander off-policy. bb-usage — display real-time usage stats and cost forecasts inside Claude. cookie-sync — sync cookies from your local Chrome into a Browserbase session. The missing piece for "log in to authenticated pages" workflows. fetch — retrieve HTML or JSON from static pages. search — structured web search results, not just a markdown dump. ui-test — AI-powered adversarial UI testing. Feed it a git diff and it runs your changes against the live UI in a real browser. How to install One command inside Claude Code: /plugin marketplace add browserbase/skills Then install the browse plugin and restart Claude Code. Each skill is a folder under skills/ in the repo and each can be enabled independently. Why this matters The headline skill is ui-test. It takes a git diff, spins up a real browser, navigates to the affected page, and runs an adversarial test pass against your UI changes. That used to require a dedicated test engineer plus a CI pipeline plus Playwright/Selenium glue. Now it's one install. For frontend teams shipping multiple changes a day, this single skill changes the economics of testing. cookie-sync is the second sleeper hit. Headless browser agents have always struggled with authenticated pages — you either build a fragile credential injector, or you bake cookies into the agent's state. cookie-sync grabs them directly from your local Chrome profile. Claude can now legitimately log into your dashboards, scrape your data, file your tickets. How this differs from other Claude skills This is operational infrastructure, not opinionated configuration. Compare it to Matt Pocock's engineering skills (curated prompts and conventions for senior engineers) and Andrej Karpathy's single-file CLAUDE.md (prescriptive style guide). Those tell Claude how to think. Browserbase Skills give Claude what to do with a browser. Pairs with The parent platform: Browserbase — the cloud-browser infrastructure these skills run on. If you're not already on Browserbase, you'll want an account before installing — most of the skills require a remote session. Status Repo created October 12, 2025. Latest commit May 13, 2026. Active development from the Browserbase team. JavaScript primary language. No explicit license file in the repo as of today — the skills are published under Browserbase's standard terms, but if you're building commercial automation on top, confirm with their team.
