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. Your account's credit balance and request limits apply across tasks.

Sign up and generate a key in your dashboard.
- 02
Launch a browser locally

Node Mantis calls the moves
Describe your task in natural language. An LLM chooses the next browser action, and your client executes it locally.
Why Node Mantis
Everything you need to automate the web
Tasks in plain English
Describe a goal in natural language. The agent uses page context to choose browser actions, with an SDK and CLI for integrating those actions into your workflow.
Multi-step workflows
Navigate pages, interact with forms and widgets, and retrieve information through a real browser.
Usage-based credit
Start with $10 in free credit, valid for 30 days; add more credit any time from your dashboard.
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.
