Reddit does not document this user agent. It is commonly reported to fetch pages for link post previews, but Reddit has not confirmed that.

Fetches a page when someone shares its link, to draw the preview card. Blocking it breaks your previews in that app.

## How to verify a request is really redditbot

Anyone can send any user agent, so the string alone proves nothing.

Reddit publishes no IP ranges or DNS names for redditbot that we could find, so there is no reliable way to tell a real redditbot from a scraper using its user agent.

## See when redditbot reads your site

Bots don’t run JavaScript analytics, so a script tag never sees them. invisit records crawler reads on the server instead, through its server SDK or a Cloudflare Worker, and shows which bots read which pages, next to your visitors.
