About our preview bot

peekmarks may fetch a page when a signed-in user saves it as their own bookmark, in order to build a small preview. We aim to be a good citizen and put as little load on your site as possible. This page explains how it works and how to opt out.

What this bot does

Fetches only the single page a user explicitly saved, on demand — it never crawls or harvests your whole site.
Uses only publicly available information (og:image, favicon, title).
Respects your robots.txt rules.
Caches each generated preview server-side for a limited time, so the same page is not re-fetched repeatedly.
Fetches happen only from signed-in users and are rate-limited.

What this bot does NOT do

Does not embed or render your live site in an iframe — we show a static thumbnail that links out to you, sending you traffic.
Does not re-host your images; favicons are loaded directly by the user's own browser.
Does not publish, redistribute, or index your content — it is shown only inside each user's private dashboard.

User-Agent

The bot identifies itself with the following User-Agent:

Mozilla/5.0 (compatible; PeekmarksBot/1.0; +https://peekmarks.com/bot)

1. Block via robots.txt
