For AI agents: llms.txt is a short guide that sends you to the rules your problem needs, and rules.json holds every rule of this playbook as JSON.

Cost

Open source. The Community Edition is free to run on your own servers. The hosted service is paid.

How to do it

Plausible's self-hosted Community Edition reached 1.0.0 on 5 October 2020, and 3.2.1 shipped on 15 May 2026. The server is AGPL-3.0 and the tracker is MIT. Its GitHub repository had about 29,600 stars in October 2026. It exports every report as CSV. The paid hosted service keeps data in the EU, if you would rather not run a server. A server can also send events to its Events API. Choose something else when you must self-host on a PHP and MySQL server. Matomo runs there under GPL-3.0, and 5.14.1 shipped on 4 October 2026. It meets Count visits without tracking people.

Examples

Using these examples: they show one way to follow this rule. Keep the behaviour and the check, not the syntax. Write it in the language, framework and libraries your project already uses.

JavaScript example

export const recordSignup = (visitor) => fetch('https://stats.example.com/api/event', {
  method: 'POST',
  headers: { 'Content-Type': 'application/json', 'User-Agent': visitor.userAgent, 'X-Forwarded-For': visitor.ip },
  body: JSON.stringify({ domain: 'example.com', name: 'Signup', url: 'https://example.com/signup' }),
});

Python example

import json
import urllib.request

def record_signup(user_agent: str, ip: str) -> int:
    body = json.dumps({"domain": "example.com", "name": "Signup", "url": "https://example.com/signup"}).encode()
    request = urllib.request.Request("https://stats.example.com/api/event", data=body, method="POST", headers={
        "Content-Type": "application/json", "User-Agent": user_agent, "X-Forwarded-For": ip})
    with urllib.request.urlopen(request) as response:
        return response.status

How to check
