# Limitations

> What agent-traffic can't tell you.

* **Agents inside a person's browser are invisible at the HTTP level.** Agentic browsers and extensions that run in a person's own browser send that browser's requests.
* **Some products share an identity.** Codex has been reported to fetch as `ChatGPT-User`, and Cursor through Exa as `ExaUser`. Results name only what can be proven.
* **Logs lose information.** Classifying stored logs from the user agent alone can't catch agents that borrow a browser user agent. See [Querying your logs](https://agent-traffic.mintlify.site/guides/querying-logs.md).
* **Very old browsers and feature phones count as bots.** User agents without a modern rendering-engine token, like Amiga browsers or MIDP phones, fall through to `bot`.
