Browserbeam

Browserbeam is an AI simulation generator tool. A hosted REST API that puts a real browser behind your AI agent or scraper, returning scoped markdown, stable element refs, form structures and change diffs instead of raw HTML. Plain-language AI selectors are cached per domain, and blockers, stability waits and session cleanup are handled server side.

Browserbeam is a hosted browser automation API aimed at developers building AI agents and scraping pipelines. Instead of driving Puppeteer or Playwright yourself and passing a wall of HTML to a model, you call a REST endpoint that opens a real browser session and returns a compressed, LLM-ready view of the page: markdown content, a list of interactive elements with short stable refs, and grouped form structures. A single POST to create a session handles navigation, viewport setup and automatic dismissal of cookie banners and popups, so common setup work disappears from your codebase. After the session exists, actions run through an act endpoint that takes a list of steps: observe a scoped section, fill a form by field label, extract structured data, scroll through lazy-loaded content, take a screenshot, or close the session. Each step returns fresh page state plus a changes object describing what shifted since the last read, which keeps the token cost of follow-up calls low. A stability signal in every response tells the agent when the page is finished loading, replacing fixed sleeps and networkidle guesses. The scraper-facing feature most teams will notice is AI selectors. In an extract schema you describe fields in plain language using the ai >> prefix (for example "ai >> the price including currency") and the engine resolves and caches a selector per domain, so repeat scrapes of the same site reuse the cached selector at no extra cost. That sidesteps the usual breakage on single page apps with hashed class names. Cookie injection, custom JavaScript execution and smart wait conditions on expressions cover authenticated and framework-heavy sites. It competes with raw Playwright, hosted scraping APIs and general browser-agent frameworks. Browserbeam sits closer to infrastructure than to an autonomous agent product: it gives your own code or LLM a controllable browser and standardizes the payload. Sessions are metered in credits, which makes cost predictable but ties usage to a hosted service rather than a local headless install.
