Moli by Lexmount is our browser engine built from scratch for AI agents. It starts faster and uses less memory than Chrome. Use Moli through Lexmount Browser, our cloud browser platform. Run multiple isolated browser sessions with proxy support while we handle the infrastructure. Let your agents browse, fill out forms, and extract data. Try it in our Playground or connect through our SDK.









Can I run multiple cloud browsers at the same time?
@jojo_li Hi JoJo! Yes—you can run multiple cloud browser sessions at the same time. Each session is isolated, so you can run separate workflows without mixing cookies or login states. The number of simultaneous sessions depends on your plan; our Pro plan includes up to 25 concurrent sessions.
What kind of workflows are you looking to run in parallel?
How complex network tasks can I automate with the Lexmount browser?
@anthony_cai
Thanks for asking! Lexmount supports multi-step browser workflows involving navigation, forms, information gathering, and decisions based on what happens along the way. Our browsers offer broad compatibility with modern websites, including JavaScript-heavy pages and dynamic interfaces.
Our CAE protocol—Content, Action, Effect gives the Agent a structured view of the page, the actions it can take, and what actually changed after each action, helping it decide what to do next.
We’ve seen strong results in our research evaluation on real-website tasks adapted from Online-Mind2Web, WebVoyager, and WebGym, showing promising capabilities for demanding, multi-step workflows.
You can use Skills and Browser CLI with your existing coding agent, build your own workflows with our Python/Node.js SDKs, or delegate the goal directly to Cloud Browser Agent.
What website and workflow do you have in mind? I’d be happy to suggest a practical starting point!
Is it easy to migrate an existing browser automation workflow to Moli by Lexmount?
@mi_leeli Yes—our Python and Node.js SDKs handle cloud session creation and lifecycle. For compatible Playwright/Puppeteer workflows, migration mainly involves replacing local browser startup with a CDP connection. Choose light for Moli and check your workflow’s browser compatibility.

Do you offer an API or CLI to programmatically control browser sessions?
@carlvert Yes! We offer a browser API, Python and Node.js SDKs, and a Rust-based CLI for managing sessions and automating browser actions. Here are the SDK docs, runnable quickstarts, and CLI:

Node.js / TypeScript: SDK · Quickstart
CLI: browser-cli-rs
How does Moli by Lexmount compare to traditional cloud browser services?
@sarasolomaker Moli is a lightweight browser engine built for AI agents. Compared with running full Chromium in the cloud, it’s designed for faster startup and lower memory usage, reducing the overhead of running many sessions. Lexmount adds elastic scaling, usage-based billing, and SDK/CLI access. We also offer Chromium for workflows that need broader browser compatibility.
Hi everyone! 👋 I’m Julia, COO at Lexmount.
My focus is helping developers take Moli from “this looks interesting” to something useful in their own workflows.
We’d love to hear what you’re building—whether that’s a research agent, a data collection pipeline, or browser automation—and what’s making the browser part difficult today.
If you try Moli and hit a roadblock, please share it here. Our team is around to help, and your feedback will help us decide what to improve next.
What’s one browser task you’d like to try with Moli?
@julia_zhu4 Thanks, Julia! Excited to see how developers use Moli in real-world workflows. Looking forward to hearing their feedback and ideas!
Does Moli support modern web standards?
@wayne66 Yes!
Moli offers comprehensive support for modern web standards, with 100% compatibility with popular frontend frameworks like Vue, React, and Angular.
It works with Playwright and Puppeteer, and downstream projects already use it for frontend framework testing, with a much lighter resource footprint than Chromium.
