How it works
Local browser, remote brain
Install the Node Mantis client and give it a task in plain language. The browser runs where you run it, and Node Mantis tells it which step to execute next. Run as many tasks in parallel as you need.
- 01
Get an API key
Sign up and generate a key in your dashboard.
- 02
Launch a browser locally
Install the Node Mantis client. It starts a real browser on your machine, headed or headless.
- 03
Node Mantis calls the moves
Describe your task in natural language. An LLM decides each step, your client executes it in the browser, and the loop runs until the task is done.
Why Node Mantis
Everything you need to automate the web
Tasks in plain English
Say what you want done, the way you'd brief a person. No investment in deterministic, fragile scripts that break every time a page changes.
High accuracy
Works where scripts fail: built for modern, complex UI. Iframes, shadow DOM, lazy-loaded content, and framework-heavy widgets are handled the way a person handles them, and long tasks of 20–40 steps stay on track.
Low cost
Expect 10–100 tasks in under $1, depending on task complexity. Pay only for the steps you run, with no minimums.
Flexible API
Drop Node Mantis into an existing workflow and decide how much to hand over: a whole task end to end, or only the steps you choose while the rest stays in your own automation.
Bring your own proxy
The browser runs on your machine, so you can route it through any third-party proxy provider you already use. Configuration stays on your side.
