If you want an AI agent to use websites, the usual answer is Playwright. It is a great tool. It is also a code library: you write a script, it starts a browser, and the agent needs that script around it.
NTXM Browser takes a different path.
What Playwright does well#
- The standard choice for automated browser tests.
- Works with several browsers and many languages.
- Full control from code.
What NTXM Browser does#
NTXM Browser Mini is a desktop browser built on Chromium that you keep open on your computer. It has a small HTTP contract at /v1, so any agent or script that can send a web request can use it:
- Observe: get a short map of the page instead of the full HTML or a screenshot.
- Act: click or type on an element by its short id.
- Extract: get the data back as JSON.
Your browser session stays on your machine. An experimental MCP endpoint is there too, but /v1 is the main way in.
