Cloud browser API for AI agentsAutomate real web tasks

Cloud Browser API provides isolated browser sessions on demand for browsing, clicking, and filling forms. Web Fetch API extracts titles, text, and links from public pages in one request. No browsers to deploy or maintain.

Web interaction and extraction

Use Cloud Browser to control cloud browsers for searches, clicks, and other interactions; use Web Fetch to extract public web content.

Perform web actions in a cloud browser

Let your agent search, click, and fill forms to gather the information it needs. This demo extracts search results with titles, links, and summaries.

    Keep web automation moving past CAPTCHAs

    Enable automatic CAPTCHA handling through the Lexmount SDK to keep web tasks moving when verification appears. Lexmount Cloud Browser completes verification and continues subsequent operations in the same session, without human takeover or restarting the task.

Browser engine selection

When creating a Cloud Browser session, choose Chromium or Moli based on your task’s compatibility, visual fidelity, and resource needs.

Runtime selection map: start with Chromium when unsure. Choose Moli only for structure-first tasks that do not require persistent Contexts, extensions, stored downloads, recording / Replay, or high-fidelity visuals.

When unsure which runtime fits, choose Chromium

  • Browser behavior and visual fidelity
  • Persistent Context
  • Extensions / downloads / recording / Replay

When your task is structure-first, choose Moli

  • DOM / text / links
  • Forms and network responses
  • Layout and screenshots on demand

Why Moli is lighter

Moli keeps the page structure and interaction state in memory, rendering only when a visual view or screenshot is needed. In observations of internal RL training workloads, Moli used about one-seventh of Chromium’s idle memory and one-third of its peak memory, with roughly five times the average cold-start speed.
