Lexmount: Give Your AI Agent a Real Browser

AI agents are great at reasoning — but much of the web still isn't built for APIs alone. Logins, dynamic pages, multi-step forms, and JavaScript-heavy sites require a real browser. Lexmount (browser.lexmount.com) provides exactly that: cloud browser infrastructure, purpose-built for AI agents.

What it is

Lexmount offers two complementary products:

Cloud Browser API — spin up isolated browser sessions on demand. Your agent can search, click, scroll, and fill in forms exactly as a human would, without you deploying or maintaining any browser infrastructure yourself.

Web Fetch API — when you don't need full interaction, extract a page's title, text, and links in a single request. Lightweight and fast for content extraction at scale.

Two engines, one API

When creating a session, you choose the runtime that fits the task:

• Chromium — full browser behavior and visual fidelity. Choose it when you need persistent contexts, extensions, downloads, or session recording and replay.
• Moli — a structure-first engine that keeps page structure and interaction state in memory and renders only when needed. In observations of internal RL training workloads, Moli used roughly one-seventh of Chromium's idle memory with about five times the average cold-start speed — ideal for DOM/text/link extraction, forms, and network responses where pixel-perfect rendering isn't required.

When in doubt, start with Chromium; reach for Moli when the task is structure-first.

Built for observability

Automation you can't see is automation you can't trust. The Lexmount dashboard lets you search sessions by ID or status, inspect a live view of a running browser, take over mid-run when needed, and review completed sessions with replay controls and run statistics.

Plugs into your stack

Connect your agent through Skills or MCP, or call the API/SDK directly from your own app. For example, you can install the Browser Skill in Codex, authorize once, and start assigning web tasks to your agent right away.

Who it's for

If you're building AI agents, web automation, or data extraction pipelines — and you're tired of maintaining your own browser fleet — Lexmount removes that undifferentiated heavy lifting so you can focus on the agent logic itself.
