Analytics for AI-agent traffic
Google Analytics can't see your most important new visitors.
AI agents read your site every day — deciding whether to recommend you. Agentlens shows you which ones, what they read, and what they can't.

How it works
Two planes of traffic. Two ways to measure.
Crawlers and humans behave differently, so Agentlens measures them differently — at the server for agents that never run JavaScript, in the browser for the humans they send you.
PLANE 01 · SERVER
Crawlers never run JavaScript.
GPTBot, ClaudeBot and PerplexityBot fetch raw HTML and leave. One middleware line records them at the edge — matched by user agent, then verified against the IP ranges each operator publishes.
npm i @agentlens/next
// middleware.ts
import { withAgentlens } from "@agentlens/next";
export default withAgentlens({ siteKey: "al_…" });PLANE 02 · BROWSER
A cookieless snippet, under 2KB.
Catches the humans AI sends you — referrals from ChatGPT, Perplexity, Copilot, Gemini — and flags likely automated browsers. No cookies, no fingerprinting, no consent banner required.
<script defer
src="https://app.agentlens.1labs.ai/al.js"
data-site="al_…"></script>Verified means user agent and published IP range confirmed. Likely means heuristics only. We label them differently everywhere, because a guess is not a fact.
Agents overview
Know every agent on your site.
Who's crawling, how often, what changed. Each agent comes with its operator, its purpose, whether it respects robots.txt — and an alert the day a new one shows up.
- ~20 agents in the registry, refreshed weekly from operator sources
- First-seen alerts: know the day Amazonbot finds you
- Per-agent trends, page lists, and robots-compliance

AI referrals
The chart that proves AI sends you customers.
When ChatGPT or Perplexity recommends you, a human clicks through. Agentlens attributes those sessions by source and landing page — so "AI is sending us customers" stops being a feeling and becomes a number you can put in a deck.
Top landing page for voltaic.dev: /docs/quickstart — 387 sessions
Readability audit
Find out what agents can't read.
Agents only recommend what they can read. The audit checks your robots.txt against every agent in the registry, your llms.txt, and whether your content survives without JavaScript — then hands you the exact fix for every failure.
Each check is run against your live site, with a copy-paste fix card — not a score with no instructions.
robots.txt allows all 14 verified agents

FIX
Server-render your changelog — agents see a 217-byte shell. Your changelog is invisible to every crawler on this page.
Weekly report
Forward it to your CEO.
Every Monday: which agents read you, what they read, what AI sent you, and the one thing to fix. A public share link, a print-clean layout, and white-label on the Agency plan — built to be the email that gets forwarded.

FAQ
Fair questions, straight answers.
Can't a bot just fake its user agent? +
Yes — and that's exactly why we have two labels. "Verified" means the user agent matched AND the request came from an IP range the operator publishes (or passed a reverse-DNS check). Spoofed UAs fail that check. "Likely" means the signals point to an agent but we couldn't confirm the source, so we say so. We will never present a guess as a fact.
What exactly does "Verified" mean? +
OpenAI, Anthropic, Perplexity, Amazon, Google, Apple and others publish the IP ranges their crawlers use. When a request's user agent matches a known agent and its IP is inside that agent's published ranges, we label it Verified. User-agent match without IP confirmation is labelled Likely — a different chip, in every table, always.
How is this different from Google Analytics? +
GA runs in the browser, so it only sees visitors that execute JavaScript. AI crawlers don't — GPTBot, ClaudeBot and PerplexityBot are invisible to it by design, and GA actively filters known bots out of reports. Agentlens measures from the server, where crawlers actually appear, then adds AI-referral tracking on top. Keep GA for humans; use Agentlens for everything it can't see.
Do I need a cookie banner to use Agentlens? +
No. The snippet sets no cookies, stores no personal data, and does no fingerprinting. It counts visits, not people — there is no identifier to consent to. (This marketing site shows a notice anyway, to say exactly that.)
What data does the snippet collect? +
Per pageview: the path, the referrer hostname, and a user-agent classification. The IP address is used once — salted-hashed for bot classification — then discarded; we never store raw IPs. Under 2KB of JavaScript, sent via a beacon. The full list is in the privacy policy, and it's short.
Can I cancel anytime? +
Yes. Billing is handled by Polar, our merchant of record — cancel in one click from the customer portal, keep access until the end of the period you paid for, and export your data for 30 days after. No retention mazes.
