Moli

What it does

Moli is a headless browser: it loads websites, runs their JavaScript and returns the content as text, Markdown, screenshots or PDF, without showing a window. It is meant for AI agents, web crawling and test automation, and tools like Playwright, Puppeteer and Selenium can control it. It is used from the command line or by connecting other programs to it, so it is aimed at developers and people who run AI agents. Ready-made versions exist for Windows, macOS and Linux. The company behind it also sells a managed cloud version, which the README says is not needed.

How easy it is to install

B · installer plus one simple step · Windows

There is a ready Windows zip (moli-x86_64-pc-windows-msvc.zip, about 42 MB) or one PowerShell install command, but it has no window: you use it by typing commands or by connecting an AI agent or automation script to it.

Infopowershell pipe iex
README.md, Direct installation: powershell -ExecutionPolicy ByPass -c "irm https://github.com/lexmount/moli/releases/latest/download/moli-installer.ps1 | iex" runs a downloaded script directly and bypasses the PowerShell script policy. Plain zip files are also offered in the releases.
AI review
Infoagent installs from repo instructions
README.md, Quick start: the suggested prompt tells your AI agent to "Install the skills under https://github.com/lexmount/moli/tree/main/skills, follow their instructions to download and install the latest prebuilt Moli binary", so the agent follows instructions written in the repository.
